Mold Testing and Remediation questions, answered by experts

The spread of wood rot results in a physical breakdown of the wood’s cellulose and lignin, causing it to become spongy or brittle. This can lead to structural damage. Water won’t damage the physical structure of the wood, while mold can eat away at the material and cause structural damage over a much longer timeframe. When further considering water damage versus mold versus wood rot, all three issues can create a musty or damp odor in the area. All three can also cause discoloration of the wood.

Mildew and mold are not different—mildew is a specific type of mold and yes, it can become dangerous if left untreated. It would be amazing if we were all biochemists but because we most likely aren’t, it isn’t wise to assume any mold is mildew on sight alone. Harmless mold and toxigenic mold (which can be deadly) look very similar, so if you see any new mold that looks even a little suspect, call a mold professional immediately.

The symptoms of mold exposure for sensitive parties include a skin rash, runny nose, coughing, sore throat, burning eyes, and even more severe allergic reactions. If you notice signs of mold exposure, contact a medical professional right away.

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

Air purifiers are meant to kill airborne mold, along with pollen and dirt. Air purifiers are a good option if you have allergies and need a whole-home solution, whereas dehumidifiers are best for naturally damp areas (like a bathroom). Consider getting an indoor air quality test to determine if an air purifier is right for you.
