Air sampling is the most popular way to measure the amount of mold in a room and perform a mold test. The number of mold spores inside the building is compared to the outside air to confirm the presence of hidden mold. Additionally, samples are taken to determine the number of mold spores on interior surfaces and perform a mold test. The mold assessment begins with an inspection by the mold inspector, during which they will observe any visible signs of mold growth and perform a mold test. They will also be on the lookout for leaks and moisture issues that could be contributing to the spore count.
In most cases, if there is visible mold growth, there is no need to take samples. Since no EPA or other federal limits have been established for mold or mold spores, samples cannot be used to verify that a building complies with federal mold regulations. Surface sampling can be useful in determining if an area has been properly cleaned or remediated. Mold sampling should be done by professionals with specific experience in designing mold sampling protocols, sampling methods, and interpreting the results.
Sample analysis should follow the analytical methods recommended by the American Industrial Hygiene Association (AIHA), the American Conference of Governmental Industrial Hygienists (ACGIH), or other professional organizations. When a mold inspection is needed, it's about making sure that potential spores are intact when professionals arrive. However, the remediation process will generally involve the contractor determining the extent of the problem, which actually consists of an inspection of the mold. The cost of mold inspection may vary slightly from region to region, but the difference is usually quite small. Humidifiers increase the moisture content of the air, which can accelerate mold growth and distort results.
If you suspect mold, a professional mold inspection is the first step to keeping your home spore-free. Mold is a serious issue, and detecting mold contamination before it spreads uncontrollably can save you thousands of dollars. Bathing or showering creates excess moisture, making it difficult to detect possible pipe leaks if the professional discovers any mold. When the spore trap is sent to the mold analysis laboratory for analysis, the mold laboratory opens the spore trap, applies some stains to the sticky surface that mold spores can absorb, and then identifies and quantifies the types of mold spores captured during the sampling process. Once mold samples arrive at the mold testing laboratory, there are many ways to test them.
Mold grows quickly in humid conditions after rain, so this could hide a problem if there are higher concentrations of mold in indoor air. If mold is detected, the inspector will try to find out what is causing it and will talk to the homeowner to develop a remediation plan. It would be virtually impossible to remove all mold spores from a home without installing some type of massive industrial filtration system for clean rooms. Nobody wants to know that you have mold in your home, but finding it early means addressing the problem before it gets worse. As a rough guideline, a mold inspection costs about as much as a normal home inspection, which is done when buying a new home. Check with your state's health department or labor department to see if mold inspectors should have a special license or certification.
