"Tony did a great job assessing the mold risk with a townhouse we were in the process of buying. He recommended testing 5 different areas, and we are glad he did. He found issues with not just the crawl space but also the living room above the crawl space. Tony also will be doing the remediation work for us. Tony knew that a comprehensive evaluation was important to us because of the health issue of two of our family members, and he responded accordingly."

"I hired him because he explained how he would remedy the problem and his method seemed the most logical. I interviewed 2 other companies. His also turned out to be the least expensive, by far. But that was not my main reason for hiring him. Also, he was the only one that guaranteed his work for 5 years."

"Pete was very up front and open about the mold issues we had and what the services would include. We had a bit of a lag getting service scheduled, but I assume they are busy and short-staffed, as many places are right now. Crew was professional and arrived on time for the work."

"Henry came to our house. He was very knowledgeable about mold and what to look for. He answered all my questions and was very helpful. Peter who called me with the results was very nice and answered my questions. He even called back the next day when he noticed that an email he sent me didn t go through. They gave me a lot of information to help me continue my search to get rid of my mold and poor air flow."

Mold Testing and Remediation FAQs, answered by experts

Mildew is a type of mold that forms in areas of excessive moisture and poor ventilation. Although it commonly exists in household air, it can’t take hold and spread if a surface is clean and dry. Generally, if you have any mildew or mold issues, it’s because the humidity in either your house, room, cabinet, or cupboard is above 50 percent. Common areas where you’ll find mildew are around water sources, which is why it’s commonly found near showers and in kitchen sinks.

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.

Yes, if installed correctly. Moisture barrier padding blocks dampness from reaching the padding core and subfloor, where mold loves to grow, especially in humid environments like basements. However, poor installation with gaps or loose seams can do the exact opposite, trapping moisture and creating mold problems. So, make sure to do your installation carefully or hire a professional.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

Efflorescence itself won’t turn into mold, but it can cause moisture problems, which can lead to mold. It’s important to address an efflorescence problem as soon as possible, as mold can pose health risks and even compromise the structure of your home.
