In a perfect world you could trust everyone, but it's not a perfect world. Like every industry, the mold business has its share of scammers and con men seeking to profit from your lack of knowledge about mold. Here are the top mold scams and tips on how to avoid them.
D A N G E R !
Mold Scam # 1:
“Duct Cleaners” using a “Field Test Kit” or “Instant Mold Test”
Many Duct Cleaning companies are owned and operated by honest and reliable owners and they offer a valuable service. However, some “Duct Cleaners” or other untrained mold inspection service providers have perfected this scam. They offer a very low “Duct Cleaning” service to get their foot in your door. When they show up to clean your ducts they offer you a free mold test OR they claim to find hidden mold in the duct work. They basically scare you into a very expensive “spray treatment” and sign you up for a regular “treatment service”. This is a very bogus and risky proposition.

How To Avoid It:
The best way to avoid this scam is to avoid using a service provider that uses “Instant Mold Tests” to conclusively determine if you have a mold problem or not. The manufacturers of these field test kits specifically state in their literature that a positive test result should be followed up with laboratory testing. Furthermore the EPA specifically recommends AGAINST using a biocide as the sole source of remediation. The biocide used by these scam artists may be much more dangerous than the mold that it is being used to control. The EPA recommends “physical removal” of any mold or mold damaged building materials. Another interesting note is that many modern homes use a vinyl or plastic “flex duct” that will not even support mold growth, but can also be damaged by improper duct cleaning. If you are going to use a firm to clean your ducts make sure that they are a National Air Duct Cleaners Association (NADCA) member and verify this yourself online – don’t take their word for it. We have had reports from consumers that these con-men always seems like the nicest and most believable guys in the industry.
 

Mold Scam # 2: Off-Site Sampling
Off-site sampling is the most blatant form of deliberate mold fraud. It is a scam often perpetuated by mold inspectors who are either in the remediation business themselves or receive referral fees from remediation contractors. It works like this: The inspector has a private shed where he stores construction materials such as drywall. The materials are periodically sprayed with water and left inside the shed where mold is allowed to grow rampant. Before coming to your property, the inspector collects samples from the shed that are sure to have very high counts of dangerous molds and then passes them off as your samples. After frightening you with the alarming results, he then urges you to take immediate action, which of course includes remediation, either by him or a contractor he is in cahoots with. The result is tens of thousands of dollars in mold remediation that never needed to be done.

How To Avoid It:
The best way to avoid this scam is to always check licensing, customer references, trade references, Better Business Bureau, and Certifying Bodies that contractors claim to be certified by. Another safeguard against off-site sampling is to ask your inspector to show you the sampling media he uses at your property. Air sampling media such as spore traps have a unique serial number printed on the by the manufacturer to identify the location from where the sample was collected. The location and corresponding serial number should be written on a Chain of Custody form and sent to an AIHA EMLAP accredited laboratory* for analysis. Ask you inspector to show you the sampling media serial numbers and confirm that the same numbers are written on the chain of custody. When you get you lab results from the lab, make sure the same serial numbers on the documents match the numbers on the sampling media and the chain of custody. Most inspectors do not supply the client with a copy of the chain of custody, so you may have to write the serial numbers down yourself, but a little bit of writing is worth the peace of mind. Some sampling media, such as tape, swabs and dust collectors, are not marked with serial numbers, which is fine, but make sure your inspector writes an identifying mark on the media and that the same mark is written on the Chain of Custody to identify its origin.

*AIHA's EMLAP accredited laboratories specialize in analysis of microorganisms commonly detected in air, fluids and bulk samples, as part of IAQ investigations. The AIHA accreditation program is a rigorous, thorough and lengthy process involving all operations and personnel of the accredited site.


Mold Scam # 3: Using Heat to Remediate Mold
Some contractors claim that applying heat to a structure is an effective way to remediate mold. This is an unsubstantiated claim. While mold can be killed by heat, as can every other living organism, there is no evidence to support the notion that heat treating a house will kill the entire mold amplification sites. Short of burning down your home, heat will not destroy all of the allergens, mycotoxins, and irritants that may be associated with mold growth.

Killing Mold Is Not the Same as Remediating Mold:
The goal of remediation is not to "kill" mold, it is to remove it. If mold is not removed, it has not been remediated - it is still in your house. The only good news about dead mold is that it stops “eating” the construction materials in your home. But mold spores, whether viable or non-viable (alive or dead) still have the same harmful effects on humans and animals.

Even if killing mold was the goal of remediation (and it is not), but even it was, there is no documentation available that supports any claim that whole-house heat treatments actually kills hidden mold. In fact, some studies indicate that hidden growth inside walls is still culturable (alive) after heat treatment.

Traditional Drying Methods Are Best:
Heat treatment technologies can help dry out a structure and slow mold growth, provided sufficient ventilation is factored into the process into remove the water vapor resulting from the heat. However, in the final analysis, traditional methods of drying, such as dehumidifiers and fans, will also dry out a building without subjecting the entire structure to the thermal stress that heat treatments cause.

How To Avoid It:
If you want to avoid exposure to molds that can affect your health, you must physically remove all mold growth (dead or alive) inside your building. If mold is not removed, it has not been remediated, and could return if moisture from humidity or water intrusion ever reoccurs. The best way to avoid this scam is with a standard remediation protocol that involves the actual removal of mold growth.


Mold Scam # 4: “FREE” Mold Inspection & Mold Testing
When it comes to mold, the general public knows little to nothing other than what they read on the internet or hear from someone who makes money selling mold-related products or services. Most people who call a mold inspector or mold removal contractor are not really sure if they have a mold problem or not. Maybe they smell something, maybe they had a toilet back up in the past, or had a flood. Perhaps they’re experiencing some unexplained health condition that they believe might be caused by mold growing in their home. It's one thing to know for certain that you have a mold problem, but quite another to not know for sure. And between the ‘not knowing’ and all the hype and scare tactics that are used to sell mold services (both inspections and remediation), it’s only natural for people to be somewhat ‘fearful’ when they call a mold removal company.

Fear is a powerful motivator and many unscrupulous mold contractors are masters at playing the fear card to create a sense of urgency in order to motivate you sign a contract right away. That is not to say that all mold remediation contractors are unscrupulous. There are many excellent contractors out there. But in these slow economic times, it is wise to beware of anyone using words like; “FREE MOLD INSPECTION”, “FREE CONSULTATION”, “FREE TESTING”, and “FREE SAMPLES” in their pitch. More often than not, free comes with a hefty price that ends up costing far more than you thought it would and never has that been more true than in the mold business.

How To Avoid It:
The safest thing consumers can do whenever the word “FREE” is used to sell a mold remediation job is to avoid that contractor all together. Think about it. No one is in business to do anything for free. Anyone offering something for free is doing so to sell you something else. While that may be fine when it comes to "buy one - get one free" deals offered on TV infomercials, in the mold business a free inspections and testing can end up costing you thousands of dollars for remediation work that may be grossly exaggerated or in some cases doesn’t need to be done at all.


Mold Scam # 5: “FREE” Post-Remediation Clearance Testing
The final step in the mold removal process is a post-remediation survey done to verify and document that the remediation was in fact successful. The survey should be done before any re-construction work begins so the inspector can visually see that there is no mold left on the remediated materials. Many mold remediation contractors offer "FREE" post-remediation clearance testing. Clearance testing is vital to the mold remediation process. Insurance companies, mortgage lenders and prospective buyers of your property in the future will want to see written confirmation that the mold issue was resolved. Post-remediation clearance testing should never be performed by a mold removal contractor waiting to get paid for his work. With thousands of dollars on the line, it is highly unlikely that a contractor will fail his own work.

How To Avoid It:
Have your post-remediation survey and clearance test performed by a Certified Mold Inspector who does not work for your remediation contractor.


Mold Scam # 6: Encapsulating Fungal Growth
Encapsulation is a trade term used by some mold remediation contractors. The goal of encapsulation is to essentially glue any remaining mold in place to prevent the release of spores. This is possible to do and may even be the preferred (or the only realistic or economic) method of choice is some cases. However, if you have fixed the water problem, dried the remediated materials and removed all of the mold growth, encapsulation should not be necessary. As a rule, encapsulation is not an acceptable stand-alone solution for a successful remediation project. For prevention purposes, there are now proven treatment products that work to prevent the return of mold to the newly installed building materials – these are not encapsulants as they are not designed to cover the mold.


Deciding To Encapsulate:
In the remediation process, contractors will scrape, sand, grind, and wire brush as much mold as they can from salvageable construction materials such as studs, ceiling and floor joists. At some point they determine that they have removed as much mold growth as possible for the amount of money they are charging you. At that point, if your contractor is confident in his work, he will inform you that your project is ready for a post-remediation survey and clearance test. If they are not completely confident that the job will pass a post-remediation air test, often times they will spray a sealant (or encapsulate) over the construction materials inside the containment area. There are four reasons and one scam reason why contractors decide to encapsulate:

The Legitimate Reasons:
• He suspects that there may still be traces of mold left in areas that cannot be accessed without major demolition and encapsulating those areas will inhibit spore release.

• He suspects there is a possibility that moisture is still a factor in or around the remediated area and, as a precautionary measure, he wants to apply a water seal treatment to the salvaged materials to protect them from that moisture.

• There are contractors who process their work to exemplary levels and then apply ‘shields’ for future prevention purposes – these contractors will allow for testing at the client’s discretion as they normally pass whether at the end of remediation or after applying their final step products.

The Scam Reason:
His work is sub-standard. He simply did a bad job of remediation the mold and to hide his poor workmanship, he uses encapsulation (usually a solid color) to "paint over" it.

How To Tell the Difference:
When encapsulation is done properly by a responsible remediation contractor, the encapsulant product preferably should be clear so that a third-party Inspector can visually see the remediated materials in this post-remediation survey and confirm that no mold growth remains. When encapsulation is done to cover up a bad job, the contractor will use a solid color encapsulant product to hide whatever mold they left behind, making it impossible for the Inspector to verify that all mold has been removed. Some actually use regular paint which insidiously provides additional moisture in support of the underlying mold issue – worsening an already costly situation.

How To Avoid It:
Before your remediation contractor begins, ask him if he intends to use an encapsulant and, if so, insist that whatever product he uses must dry clear. No solid color encapsulates. Secondly, before your contractor applies an encapsulant, ask him to take you into the containment area (the work area) and explain to you why he believes encapsulation is necessary. This is different than a professional contractor who has performed the necessary remediation and then applies a preventive shield – ask about their warranty coverage to uncover any suspect disclaimers or restrictive limits of liability.


Tips on Encapsulation:
Before encapsulation can be considered:
• Whatever water problem that occurred which led to mold growth must be corrected so that it is unlikely to occur again. Mold will grow on encapsulating materials if the get wet.

• All mold growth has been removed from surfaces where it is possible to remove it. Encapsulating is not an alternative to mold removal.

• The substrate or surfaces to be encapsulated must be completely dry. Otherwise mold will grow right through the encapsulant.

• Encapsulating mold growth may not be safe or an adequate safeguard where immunocompromised people live.

• Encapsulating should be considerably less expensive than actually removing all of the mold contaminated materials. Encapsulation is not a permanent fix. Completely removing all of the contaminated material is always best.

• Encapsulants are very limited in their effectiveness and should not be confused with anti-microbial bonding agents that work specifically to deny mold spores the ability to grow by separating them from their food sources. Encapsulants, by their nature and design, leave mold spores in place on their food sources and are not effective in inhibiting future growth and damage.


Mold Scam # 7: Ozone Generators Being Provided Directly to Consumers
There are many legitimate uses and professional users of Ozone; however, some distributors of ozone generators have jumped on the mold bandwagon and are selling their products DIRECTLY to untrained consumers.

Resellers and dealers of ozone generators may make false statements about the ability of ozone air purifiers to kill mold, this may be true, but Ozone is as harmful to you as it is to the mold. False advertisements of ozone devices often use misleading terms such as "energized oxygen" and "pure air" suggesting that ozone is a healthy kind of oxygen. The fact is, ozone is a toxic gas with vastly different chemical and toxicological properties from oxygen. Claims that ozone generators sold as air purifiers are effective at controlling indoor air pollution are simply not true. Companies that provide ozone treatments as part of their service usually are well trained in the application and do not allow pets, people, or your priceless oil paintings to be in the area during ozone application

Several federal agencies have established health standards or recommendations to limit human exposure to ozone. The U.S. Food and Drug Administration (FDA) has established an ozone level of .05 ppm (parts per million) as the maximum level allowable in an enclosed spaces. Relatively low amounts of ozone can cause chest pain, coughing, shortness of breath, and, throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections. Exercise during exposure to ozone causes a greater amount of ozone to be inhaled, and increases the risk of harmful respiratory effects (US EPA, 1996a, 1996b).

Some manufacturers and resellers of Ozone Generators sold as air purifiers claim that these products help to control mold. According to the Environmental Protection Agency, however, (EPA) these products may very well add to indoor air pollution.
In fact, results from controlled studies show that some ozone generators produce unsafe concentrations of ozone even when a user follows the manufacturer’s operating instructions.

Buyer Beware:
Beware of misleading advertising claims stating of implying that a particular brand of ozone generator is "EPA APPROVED". Several brands of ozone generators have EPA establishment numbers on their packaging. This number helps EPA identify the specific facility that produces the product.

THE DISPLAY OF THIS NUMBER DOES NOT IMPLY EPA ENDORSEMENT OR SUGGEST IN ANY WAY THAT EPA HAS FOUND THE PRODUCT TO BE EITHER SAFE OR EFFECTIVE.

The EPA does not certify air cleaning devices, recommend air cleaning devices or endorse manufacturers of air cleaning devices. For more information from the EPA regarding the use or effectiveness of ozone generators, please visit their web site at: http://www.epa.gov/iaq/pubs/ozonegen.html


Mold Scam # 8: Insurance Scams
It's hard to imagine insurance companies doing anything improper or unethical. But like any company in business to make money, what is proper or improper, ethical or unethical, right or wrong, is not defined by moral absolutes or standards. It is defined by legal technicalities. Fairness, integrity, and conscience are nice words to flaunt. But the bottom line is always comes down to profit margins, not nice words.

Here are some profit-driven business practices of insurance companies to look out for. (DISCLAIMER: Not ALL insurances companies)

1. Hiring only "preferred" inspectors and remediators who are loyal to the insurance companies (not the insured) and who will not look too hard for mold.

2. Requiring preferred testers to restrict the air flow of their sampling pump to purposely lower the spore count in air samples.

3. Requiring the inspector to inspect only, and not sample.

How To Avoid It:
The best way to avoid getting one-sided mold information is to hire your own professionals. More unbiased reporting, hire a mold inspector board certified by the American Council for Accredited Certifications (ACAC). For proper mold removal, hire a mold remediation contractor trained by the Institute of Inspection, Cleaning and Restoration Certification (IICRC) or ACAC Certified. For reconstructing your project after remediation, hire a professional licensed by the Contractors State License Board.
