Mold Testing: How To Test Your Home or Business for Mold

If you believe you are experiencing poor air quality or have noticed water stains or recurring leaks in your home or office building, it is important that you have samples collected for mold. While most mold types are not harmful under typical outdoor conditions, increased levels of mold in your home and certain types of mold can exacerbate allergies and, lead to more serious respiratory or other conditions. If you have decided to test your mold, there are two approaches that you can choose.

Mold Testing Option #1: (Self Inspection)

One option available to you is to collect the samples on your own and then take them to a laboratory for analysis. The obvious locations to collect samples are near any leaks or where you have noticed water stains. In addition, you may want to collect samples anywhere that you detect an unusual odor. The difficulty in collecting mold samples on your own, however, is that you may not test all the necessary locations and the interpretation of results is difficult to a non-professional. The average person may overlook hidden mold sources, or may have difficulty testing certain inaccessible areas.


Is less expensive


Difficult to do correctly without training

Can easily overlook certain suspect areas or hidden mold sources

Complication with interpreting laboratory results & tough decisions about how to remedy mold problems

Mold Testing Option #2: (Professional Mold Inspection)

The other option available for mold testing is to contact a professional mold inspector to collect samples and thoroughly evaluate the indoor environment. They are familiar with current guidelines and have the necessary knowledge and skill to gather samples from your carpet, wall and ceiling cavities, all types of surfaces, as well as the air for potential mold problems. Since mold growth can occur almost anywhere, only an experienced person will be capable of identifying if the levels in your home or place of business are irregular.


Familiar with current guidelines

Can find hidden mold sources

Have the equipment to test rugs, walls, ceilings, air, etc.

Provide detailed description of recommendations to mitigate mold and reduce future mold growth


Is more expensive, although doing it yourself may ultimately cost more because you may still need to hire the professionals to interpret results more thoroughly evaluate the home, and give detailed recommendations.

What to Look for in a Mold Testing Company

Choose a mold testing company that does their lab work in house for faster results

Choose a company that specializes in mold testing, and does not perform mold remediation, because of the potential conflict of interest.

After you get your results from your mold testing company, you can then contact a mold remediation company in your area if the results determine you have a mold problem.

Why Hire A Mold Inspector?

While collecting samples on your own for mold may be less costly than hiring a professional experienced mold inspector, you will not be able to collect samples from all of the locations where mold is potentially growing. Mold inspectors are aware of current guidelines and practices for testing for mold, including mold that can be hidden within the walls, in your attic, or in your basement. It is important to keep in mind that mold does occur naturally, and only a professional can determine if the indoor levels of mold detected exceed normal levels.

If you previously had mold detected, when you sell your home you legally maybe required to disclose this information. You should expect that some buyers may be concerned to see that you previously had a problem, and that may affect their purchase decision or the price that they offer. After having the mold removed, you will want to contact a professional mold inspector to evaluate the remediation process so that you can provide documentation that your home was examined and found to be free of the mold problem. Having proof that your home was independently and professionally inspected goes a long way toward making potential buyers feel comfortable with purchasing your home.

In addition to preparing for a real estate transaction, there are many other reasons homeowners should contact mold inspectors. You should call a mold inspector if you notice any of the following:

A moldy or musty odor, especially after a heavy rainfall or during the hot humid weather

Stained or discolored walls or ceilings

Leaking windows

Siding that has not been properly maintained

Evidence of chronic leaks

Building materials exposed to moisture for longer than 48 hours

A qualified mold inspector will come to your home and test many areas for mold including floors, walls, ceilings, attics, basements, wall cavities, rugs, and the air. If excessive mold is identified, you will likely need to hire a mold remediation company to have the mold completely and safely removed. After remediation, it is recommended that you have your home inspected a second time to make sure that remediation was successful.
