How much does Home Inspection Mold Testing Lakeway cost?

The cost for mold removal will differ dependent upon many factors, for example, what number of square feet of mold was discovered, was asbestos tried and comes about were sure, is lead paint an issue, does it stretch out in behind kitchen or restroom cupboards, can the region be sealed off effectively, is there a great deal of materials to be cleaned and disinfected, has additional damage happened because of the mold damage, and so on. With such a large number of factors, it is exceptionally difficult to nail down a cost unless an expert evaluation has been.

The greatest concern a mold remediation is containing the mold and setting a negative pressure environment to prevent further contamination. The use of HEPA filtration units are essential in ensuring the health of workers and building tenants. The reason this is so imperative is that individuals are more inclined to health concerns when exposed to specific species as well as vast amounts of mold spores and amid the removal procedure the spores become airborne.

  1. Distinguish the cause of the mold growth
  2. Decide whether moisture source has been removed
  3. Determine the type of mold

Ordinarily, a private mold assessment will cost from $350 to $2000. Business mold assessments will commonly go from $750-$5,000.

The three most critical factors in deciding a definitive cost of a mold remediation venture are the accompanying:

  1. What amount of the house or business has mold?
  2. What sort of materials is contaminated?
  3. How simple is it to get to the mold?

Mold remediation undertakings can extend from two or three thousand dollars over ten thousand dollars.  The mold remediation undertaking will run from $1,700 to $9,000 while most business ventures are typically more. On the off chance that asbestos containing materials are found to be present the cost will  rise. You shouldn’t simply run with the least expensive quote, enlist the firm that will do the best mold removal and guarantee that the activity is done well and remain behind their work!

Mold & Moisture

The crawl space is the number one source for potential moisture entering your home. The moisture may be equal to gallons of water but in vapor form and not even visible. A seal tight liner kit will instantly stop the moisture in the crawl space from entering home as well as eliminating radon gas, musty odors, mildew and mold.

"The U.S. EPA states: "Molds are usually not a problem unless mold spores land on a wet or damp spot and begin growing. Molds produce allergens, irritants and potentially toxic substances. The key to mold control is moisture control. The mold will not grow if moisture is not present (source: EPA " A Brief Guide to Mold, Mildew and Your Home," publication #402-K-02-003)."

Eliminate the Existing Mold

To eliminate and prevent future mold growth, spray the affected areas with a mold killing and growth preventing spray, there are good products for purchase at your local building supply house.

My Take on the Problems with Bleach

The Myth Of Using Bleach To Kill Mold! Mold has a root system that actually grows into the surfaces of wood, drywall, concrete, etc..., like tree roots grow into the soil. The roots are not killed by bleach alone because the bleach does not penetrate the surface of porous materials. The bleach chemical portion sits on the surface until gassing off, killing only the mold on the surface leaving the roots intact, while the water portion of the bleach soaks into the material giving the mold roots a food source to start growing again. Think of it this way, if you were to cut a tree, plant, grass, or anything that has roots down and you water the area, you will see what you cut start to grow again. This is because the roots were not killed. The other problem with using bleach for an extended period is that if sprayed on wood and other building materials it actually starts to break down the products.

STOPPING MOLD AT THE ROOTS IS THE ONLY WAY!!!

Chlorine Bleach is NOT a registered EPA Mold Killing product!

If you think that we're just knocking bleach. Don't take our word for it! Go to http://epa.gov/mold/moldcourse/index.html and read what the EPA has to say about using bleach to kill mold. The EPA says that "The use of bleach is not recommended as a routine practice during mold clean-up" http://iaq.custhelp.com question #7.

Now you might ask: How do I kill mold if not with bleach?

Answer: Use an EPA approved and registered fungicide to kill the mold at its roots.

Mold Mitigation

Interesting Facts About Home Inspection Mold Testing Lakeway

Mold: it's everyone's worst enemy. So what should you do when you discover that you have a problemin your home?

Most people tend to think that you can take care of the problem yourself. With so many mold removal "How To" articles on the internet, if you're brave enough, you might just go for it. Unfortunately, most people do not have access to proper protection gear or even proper removal disinfectants. Well what about bleach? Unfortunately, the notion that bleach kills fungus is false. Bleach merely "bleaches" the color out while the roots remain intact and continue to grow. Furthermore, you need to do more than just kill it, you have to remove it.

To remove mold, a series of steps must be taken with great safety. From properly removing the fungus and the affected surface to proper disposal (even dead fungus gives off volatile organic compounds and is a potential allergen). For example, a common misconception that consumers come across is that you can effectively remove mold from your bathroom tile. Again, most so called mold killers commonly available on the market are made of bleach. Truly, the only way to remove the fungus from your shower stall is to completely remove the grout and re-grout the tile with a new application.

If you have a small mold problem, then perhaps removing it yourself is the best choice for you. If you do decide to remove mold by yourself, be sure to wear a proper respirator or mask especially made for mold spore protection, as well as eye protection and industrial rubber gloves. Also, keep in mind that the clothing you are wearing will need to be washed immediately after your procedure. If, however, you have a sprawling mold problem, like black mold growing around all of your windows, as well as in your bathrooms, it would be wise to contact a mold removal company. Mold is not only unsightly; it poses health risks as well such as severe headaches, fatigue, sinusitis and asthma to name a few. Taking care of your mold problem today will lead to a happier and healthier tomorrow.

Mold is a type of tiny living organism from the fungi family. The spores thrive on moisture and they spreads rapidly with the presence of moisture. They can grow on any materials and surfaces, in particular on objects made of cellulose.

Recent studies show that most of the homes are having some sort of mold infections due to unknown indoor moisture problems. This leads to the rapid growth in damp areas like bathroom, water-damaged basement, leaking pipes and roofs. Indoor mold growth poses great health threats and should be removed quickly to prevent it from spreading. Thus mold detection is very important, one should be very observant to the presence of this tiny organism and take appropriate actions to stop it from mushrooming.

5. DIY test kits for mold detection.

Get yourself a do-it-yourself test kit to help detecting harmful molds in your home. These test kits can be obtained from most of the home improvement and hardware stalls. They are easy to use, by following the instructions you are able to get the results instantly.

6. Get help from certified inspector.

When you are experiencing mold exposure like symptoms but fail to detect any presence of this hazardous living organism, you can get help from certified mold inspectors. Their expertise in mold detection can help to identify the exact spots of possible hidden growth.

Mold Damage

Which Home Inspection Mold Testing Lakeway service provider is performs 24/7 water damage services?

As a new homeowner, you are probably trying to learn as much as possible about your house and its inner workings. Unfortunately, most people overlook the complexities of their ductwork. With air conditioning and heating units becoming a necessity for modern life, it is important to be aware of the importance of maintaining your air passages for optimal living conditions. Take a look at the following five facts concerning these important structures:

1. Ducts are enclosed passages that channel air throughout your home.

The first step to learning about your ductwork is being able to understand what a duct is. All homes with HVAC hold ducts within their walls. These are enclosed passages that move air. When your unit blows cold (or hot) air into the home, it needs to be able to remove the old air to ensure not only energy efficiency but also maintain the quality of air. Therefore, a duct system is able to supply air, remove air, and ventilate the atmosphere. The ductwork simply refers to the entire system, including the planning, sizing and layout of the channels.

2. Dirty ductwork can be responsible for sinus problems.

Since these tubes transport air, there is always a risk of mold, dirt and dust building up within the system. If you do not properly maintain the channels, you run the risk of creating an environment perfect for allergens. This may not affect some people, but others who are prone to allergies may suffer issues with their sinuses. Small children and the elderly may be particularly vulnerable to poor air circulation and dirty ducts. If you find yourself suffering from allergies more than usual, you may want to consider having your ductwork professionally inspected and cleaned.

3. Sheet metal is the best material for a duct.

These insular tubes can be comprised from different materials. Some are made of galvanized steel, while other structures utilize aluminum. Fiberglass is another option, as well. However, sheet metal is probably the best option for constructing the airflow. With this material, leaks seem to be less common and mold growth is limited. As a bonus, sheet metal lasts longer and is easier to maintain.

4. Poor ductwork can cause significant problems with AC units.

Just like moldy ducts can irritate sinuses and exacerbate allergies, poorly maintained ductwork can interfere with your HVAC unit. Mold and other dust and allergens can back up into your system, causing malfunctions. Broken tubes will also cause systems to run for longer times, causing the potential for an early blowout and overheated units. To mitigate the problems of your ductwork, have someone inspect the channels regularly. Paying to prevent a problem may be less expensive than dealing with an actual issue.

5. Cleaning the ducts in your home can improve airflow and save you money.

Again, the most important thing for a homeowner to realize about their home air supply is that regular maintenance can save money and time. Not only does cleaning your ductwork regularly help your AC unit to run more efficiently, but it also improves the air quality in your home, thereby improving the health of all who live in your house.

Best Tips for Home Inspection Mold Testing Lakeway

Before a person ever decides to search for the best mold inspection company in their area, they should first know a few facts:

1. In the author's opinion, every house on the planet has mold in it. Mold is a member of the Fungi family and exists naturally in our environment. It is airborne and enters our houses whenever a door or window is open and in numerous other ways.

2. Inside of a house, mold will not be a problem unless it has been exposed to water for more than 48-72 hours. So, if you have seen, or know of evidence of water inside your house and you suspect that it has been there for at least 48 hours, you are most certain to have harmful (toxic) mold.

3. Even if you can't see any water, it still may be lurking behind your walls, sinks, or tubs; perhaps under windows or other locations. If you can smell a musty or unpleasant odor (some in the family may detect it while others can't), you have a harmful mold problem.

4. If you or other members of your house have asthma, other respiratory problems, coughing, runny nose or eyes, headaches, or tend to feel much better when you are away from the house and worse when you are in it, you almost certainly have a mold problem.

Knowing that you likely have a mold problem but not knowing what to do next, speaks volumes in favor of hiring a professional. But which one? You could likely have several mold inspection companies to chose from on sites like Yahoo or Google; but how does a homeowner find the best one for their needs?

My advice is: First I recommend that the company specializes in mold. Not mold and/or radon, lead, air ducts, etc. Next, I recommend that they have both education and experience at least equal to or better than their competitors. While most every state requires that home inspectors be licensed, only two states require so of mold inspectors.Are they certified? This would tell you that they cared enough about their profession to acquire knowledge and training to meet standards. Experience counts. How long has the inspector been certified? How many jobs have they performed? Not just the company, but the individual inspector? Can they get references? Have they been cited by the Better Business Bureau for any deceptive, misleading, or dishonest practices?

The next criteria is critical: Are they also in the business of mold remediation or removal? If they are it could be a blatant conflict of interest. Wouldn't it be to there interest to overstate the level of mold problems and/or the amount of remediation needed if they were in line to pick up a job worth several thousands of dollars? Therefore, I recommend that you find a professional who only inspects for mold.

OK, so now how should your inspector look for and find your problem? When they are finished will they be able to tell you for certain where your mold is and why you have the problem? Isn't that how you would like to spend your money?

Testing for mold is most often done by the old fashioned method called air testing. This procedure sucks air into a machine that then traps it into a laboratory testing dish, which in turn gets sent to a laboratory for culturing. This process can take a week or more for the results. When air testing is performed, the inspector should always take one test outside of the house in order to determine a benchmark as to what mold(s) are prevalent in your area. They then will try to take as many tests inside of the house as the customer can afford. In most areas of the country, these tests cost about $100 each. Some of the problems with air testing are:

1. The more tests that are performed, the more costly the job.

2. Air testing is highly inaccurate. All it can do is to tell you what was in the air at that location at that moment in time. Results can vary widely over time and method used. Airborne fungal spore concentrations vary greatly over the course of hours, days, weeks, and seasons.

3. In colder climates when there is snow on the ground, the results of the outside test will be useless in that spore count is greatly or totally reduced. I have yet to hear that a customer was told this fact.

4. There are no numerical standards to which tests can be prepared, making interpretation difficult.

5. Even the best tests can not determine how much exposure people in the house have had in the past.

6. Fungal air tests are expensive.

7. Results are slow to receive.

8. Knowing the type of mold does not change the way that you would respond. All mold that is active, or was active, is bad mold.

Then what does represent a professional, accurate, and helpful mold inspection? The most intelligent inspections should: Find all mold. Determine the cause; i.e. Where is the water problem(s). Explain how to fix the problem(s).

This inspection requires work, experience, and knowledge. It is also labor intensive; lasting about 2 hours or more on average. It begins with an intensive investigation of the property outside of the house. It finds flaws in roofs, chimneys, gutters, downspouts, foundations, and/or landscaping. In short, anywhere and any way that water could get into the house and cause a problem. Then, moving inside the inspection closely is conducted looking throughout the house, basement, and attic for issues under windows, sinks, tubs, showers, washer and dryers. Tools such as moisture meters, hygrometers, and boroscopes should be utilized as appropriate.

Following that, in my inspections, I work with a Certified Mold Dog. Together we systematically cover every inch of the house. Dogs such as mine have the ability to detect the scent of mold in one part per trillion. Humans are limited to one part per hundred. Two university studies are known that matched dogs scenting ability versus that of machines. Dogs won easily both times. Dogs have the ability to detect the scent of mold from behind walls, floors, or ceilings where it often is found. No machine can do that. With their ability to pinpoint the location of the mold, remediation costs are reduced to a fraction of what they may have been, or eliminated entirely.

Lastly, the customer should ask for, and receive a professionally written report that captures all that was seen, found, and measured during the inspection and remediation recommendations. This is how my company, Mold Rover, Inc. operates. It is what I think the customer needs and deserves for their money.

Interesting Facts About Home Inspection Mold Testing Lakeway

In order to remove bathroom mold, you will need a solution that can remove the source of the black mold. When cleaning mold and mildew, you have to observe the perimeter wall and also look for any sources of moisture. If you have black mold and mildew in your bathroom, it is most likely causing a problem with you and your family. By having these toxins which the spores produce, it will cause serious mold health effects. When removing mold, you will have to be sure to remove the source of the problem. Since mold and mildew are attracted to moisture and also need something to eat, you will have to find these sources. In more times than most, black mold and mildew grows on the wall because the wall is a building material which is a food source. When you have a high humidity value inside the areas of the bathroom, you will see dark spots of the black mold growing.

If you were to live with black mold in your house, you would feel some signs and symptoms of the toxins which the black mold delivers. These symptoms are caused from the excrement of the mold and mildew. Excrement is really the digestion of the mold and mildew. After eating off the walls of the home, the black mold delivered excrement which is toxic. Thus, while you and your family have mold issues.

In order to effectively remove the spores of the mold, you will need to find the source of the problem. If you have a water leak or some type of moisture intrusion, then you will need to find the source of this problem. By just removing the mold on the walls, and ignoring the source of the problem, you will still have a mold problem guaranteed. What mold inspections are about is finding the source of the problem. If you are clever enough to know there is a moisture problem you can then go ahead and attack the area using a natural cleaning product. Be sure when using natural cleaning products that they are strong enough to remove black mold effectively. Natural cleaning products are all about using regular household ingredients, but will effectively remove and prevent mold and mildew. The challenge with most green cleaning products is that they are not tough enough to destroy mold and mildew. Let me give you an example, most people will use bleach to remove the spores of the mold and mildew. But what happens here, is the mold is only removed temporarily. By using bleach you are only removing the topical surface of the problem. It is not attacking the source or changing the DNA make up of the mold and mildew. There is a natural ingredient out there which cleans mold and mildew and also creates a barrier to prevent mold growth.

By removing mold spores effectively, you will need to make sure the source is controlled. In order to control the source of the problem with mold. You will need a solution that creates a clear barrier or shield from you and the mold. This process is called an encapsulate. The encapsulate is a way which mold and mildew will suffocate because there is no source of food allowed. By protecting the walls of your bathroom, walls of your house, and other building materials, you have an ability to prevent the growth of mold and mildew. The challenge with black mold and mildew is taking away the source of the problem. Using bleach will only remove mold temporarily. If you are serious and have bathroom mold on your walls and in your house, then you need a strong natural cleaning product to kill mold. The natural cleaning product should be organic due to the harsh chemicals in other cleaning products. Have a look at Safe Shield to use as an effective natural cleaning product against mold and mildew. Safe Shield is also an organic solution and combined with Molderizer, it is a strong combination to effectively remove black mold and also prevent it from coming back. To increase the indoor air quality of your home, try an organic cleaning solution that will remove and prevent mold from ever coming back.

There may be many times when indoor mold growth may be difficult to find. It can be hidden behind walls, under surfaces, and inside unreachable areas where the visibility is almost impossible. Just because it's invisible doesn't mean it's undefeatable, however. Here's how to spot hidden mold dangers and make your home a little more livable in this toxin filled world.

One of the most common indications that you may have invisible mold growing in your home is a water leak. If you've had any recent flooding, roof damage or a plumbing leak, you may have a mold problem. Look around the areas where the leak occurred for moisture.

If you still can't find the source of the problem, you may want to call on a professional to help you find any hidden mold dangers in your home. This may seem like an expensive alternative, but remember that mold can turn into a serious problem if they are not resolved quickly. It's always better to be safe than sorry.

Mold Home Inspection

  (Redirected from Mold growth, assessment, and remediation)

Mold (American English) or mould (British English) is part of the natural environment. Outdoors, molds play a part in nature by breaking down dead organic matter such as fallen leaves and dead trees; indoors, mold growth should be avoided. Molds reproduce by means of tiny spores. The spores are invisible to the naked eye and float through the air. Mold may begin growing indoors when spores land on moist surfaces. There are many types of mold, but all require moisture for growth.

Molds are ubiquitous, and mold spores are a common component of household and workplace dust. In large amounts they can be a health hazard to humans, potentially causing allergic reactions and respiratory problems.

Some molds produce mycotoxins that can pose serious health risks to humans and animals. "Toxic mold" refers to molds which produce mycotoxins, such as Stachybotrys chartarum.[1] Exposure to high levels of mycotoxins can lead to neurological problems and death. Prolonged exposure (for example, daily exposure) can be particularly harmful.

Symptoms of mold exposure may include nasal and sinus congestion; runny nose, eye irritation; itchy, red, watery eyes, respiratory problems, such as wheezing and difficulty breathing, chest tightness, cough, throat irritation, skin irritation (such as a rash), headache, and persistent sneezing.[2]

Infants may develop respiratory symptoms as a result of exposure to Penicillium, a fungal genus. Signs of mold-related respiratory problems in an infant include a persistent cough or wheeze. Increased exposure increases the probability of developing respiratory symptoms during the first year of life. Studies have indicated a correlation between the probability of developing asthma and exposure to Penicillium.[3]

Mold exposure has a variety of health effects, and sensitivity to mold varies. Exposure to mold may cause throat irritation, nasal stuffiness, eye irritation, cough and wheezing and skin irritation in some cases. Exposure to mold may heighten sensitivity, depending on the time and nature of exposure. People with chronic lung diseases are at higher risk for mold allergies, and will experience more severe reactions when exposed to mold. Damp indoor environments correlate with upper-respiratory-tract symptoms, such as coughing and wheezing in people with asthma.[4]

Molds are found everywhere, and can grow on almost any substance when moisture is present. They reproduce by spores, which are carried by air currents. When spores land on a moist surface suitable for life, they begin to grow. Mold is normally found indoors at levels which do not affect most healthy individuals.

Because common building materials are capable of sustaining mold growth and mold spores are ubiquitous, mold growth in an indoor environment is typically related to water or moisture and may be caused by incomplete drying of flooring materials (such as concrete). Flooding, leaky roofs, building-maintenance or indoor-plumbing problems can lead to interior mold growth. Water vapor commonly condenses on surfaces cooler than the moisture-laden air, enabling mold to flourish.[5] This moisture vapor passes through walls and ceilings, typically condensing during the winter in climates with a long heating season. Floors over crawl spaces and basements, without vapor barriers or with dirt floors, are mold-prone. The "doormat test" detects moisture from concrete slabs without a sub-slab vapor barrier.[6] Some materials, such as polished concrete, do not support mold growth.

Significant mold growth requires moisture and food sources and a substrate capable of sustaining growth. Common building materials, such as plywood, drywall, furring strips, carpets, and carpet padding provide food for mold. In carpet, invisible dust and cellulose are food sources. After water damage to a building, mold grows in walls and then becomes dormant until subsequent high humidity; suitable conditions reactivate mold. Mycotoxin levels are higher in buildings which have had a water incident.[7]

Although this home experienced minor exterior damage from Hurricane Katrina, small leaks and inadequate airflow permitted mold infestation.

Mold is detectable by smell and signs of water damage on walls or ceiling, and can grow in places invisible to the human eye. It may be found behind wallpaper or paneling, on the inside of ceiling tiles, the back of drywall, or the underside of carpets or carpet padding. Piping in walls may also be a source of mold, since they may leak (causing moisture and condensation).[8]

Spores need three things to grow into mold: nutrients - cellulose (the cell wall of green plants) is a common food for indoor spores; moisture - To begin the decaying process caused by mold; time -mold growth begins from 24 hours to 10 days after the provision of growing conditions.

Mold colonies can grow inside buildings, and the chief hazard is the inhalation of mycotoxins. After a flood or major leak, mycotoxin levels are higher even after a building has dried out.[7]

Food sources for mold in buildings include cellulose-based materials such as wood, cardboard and the paper facing on drywall and organic matter such as soap, fabrics and dust-containing skin cells. If a house has mold, the moisture may originate in the basement or crawl space, a leaking roof or a leak in plumbing pipes. Insufficient ventilation may accelerate moisture buildup. Visible mold colonies may form where ventilation is poorest and on perimeter walls (because they are nearest the dew point).

If there are mold problems in a house only during certain times of the year, the house is probably too airtight or too drafty. Mold problems occur in airtight homes more frequently in the warmer months (when humidity is high inside the house, and moisture is trapped), and occur in drafty homes more frequently in the colder months (when warm air escapes from the living area and condenses). If a house is artificially humidified during the winter, this can create conditions favorable to mold. Moving air may prevent mold from growing, since it has the same desiccating effect as low humidity. Molds grow best in warm temperatures, 77 to 86 °F (25 to 30 °C), although growth may occur between 32 and 95 °F (0 and 35 °C).[9]

Removing one of the three requirements for mold reduces (or eliminates) new mold growth: moisture; food for the mold spores (for example, dust or dander); and warmth since mold generally does not grow in cold environments.

HVAC systems can produce all three requirements for mold growth. The air conditioning system creates a difference in temperature, encouraging condensation. The high rate of dusty air movement through an HVAC system may furnish ample food for mold. Since the air-conditioning system is not always running, warm conditions are the final component for mold growth.

The first step in assessment is to non-intrusively determine if mold is present by visually examining the premises; visible mold helps determine the level of remediation necessary. If mold is actively growing and visibly confirmed, sampling for its specific species is unnecessary.[8]

Intrusive observation is sometimes needed to assess the mold level. This includes moving furniture, lifting (or removing) carpets, checking behind wallpaper or paneling, checking ventilation ductwork and exposing wall cavities. Detailed visual inspection and the recognition of moldy odors should be used to find problems. Efforts should focus on areas where there are signs of liquid moisture or water vapor (humidity), or where moisture problems are suspected.

The United States Environmental Protection Agency (EPA) does not generally recommend sampling unless an occupant of the space has symptoms. Sampling should be performed by a trained professional with specific experience in mold-sampling protocols, sampling methods and the interpretation of findings. It should be done only to make a particular determination, such as airborne spore concentration or identifying a particular species. Before sampling, a subsequent course of action should be determined.

In the U.S., sampling and analysis should follow the recommendations of the Occupational Safety and Health Administration (OSHA), National Institute for Occupational Safety and Health (NIOSH), the EPA and the American Industrial Hygiene Association (AIHA).

Types of samples include air, surface, bulk, and swab. Air is the most common form of sampling to assess mold levels. Indoor and outdoor air are sampled, and their mold-spore levels compared. Air sampling often identifies hidden mold. Surface sampling measures the number of mold spores deposited on indoor surfaces, collected on tape or in dust. Bulk removal of material from the contaminated area is used to identify and quantify the mold in the sample. With swab, a cotton swab is rubbed across the area being sampled, often a measured area, and subsequently sent to the mold testing laboratory. Final results indicate mold levels and species located in suspect area.

Multiple types of sampling are recommended by the AIHA, since each has limitations; for example, air samples will not identify a hidden mold source and a tape sample cannot determine the level of contamination in the air.[10]

Mold remediation

The first step in solving an indoor mold problem is to remove the moisture source;[11] new mold will begin to grow on moist, porous surfaces within 24 to 48 hours. There are a number of ways to prevent mold growth. Some cleaning companies specialize in fabric restoration, removing mold (and mold spores) from clothing to eliminate odor and prevent further damage to garments.

The effective way to clean mold is to use detergent solutions which physically remove mold. Many commercially available detergents marketed for mold cleanup include an EPA-approved antifungal agent.[12]

Significant mold growth may require professional mold remediation to remove the affected building materials and eradicate the source of excess moisture. In extreme cases of mold growth in buildings, it may be more cost-effective to condemn the building than to reduce mold to safe levels.[13]

The goals of remediation are to remove (or clean) contaminated materials, preventing fungi (and fungi-contaminated dust) from entering an occupied (or non-contaminated) area while protecting workers performing the abatement.[14]

The purpose of cleanup is to eliminate mold and remove contaminated materials. Killing mold with a biocide is insufficient, since chemicals and proteins causing reactions in humans remain in dead mold. The following methods are used.

Equipment used in mold remediation includes: moisture meter: measures drying of damaged materials; Humidity gauge: often paired with a thermometer; borescope: Camera at the end of a flexible snake, illuminating potential mold problems inside walls, ceilings and crawl spaces; digital camera: Documents findings during assessment; personal protective equipment (PPE): Respirators, gloves, impervious suit, and eye protection; thermographic camera: Infrared thermal-imaging cameras identify secondary moisture sources.

During mold remediation in the U.S., the level of contamination dictates the protection level for remediation workers.[16] Contamination levels have been enumerated as I, II, III, and IV:[17]

After remediation, the premises should be reevaluated to ensure success.

According to the EPA, residential mold may be prevented and controlled icy cleaning and repairing roof gutters, to prevent moisture seepage into the home; keeping air-conditioning drip pans clean and drainage lines clear; monitoring indoor humidity; drying areas of moisture or condensation and removing their sources; treating exposed structural wood or wood framing with an EPA-approved fungicidal encapsulation coating after pre-cleaning (particularly homes with a crawl space, unfinished basement or a poorly-ventilated; attic).[8]
