"They did a very good job of remediation as far as I can tell, but David wasn't quite truthful about two things he told me. They also put my stuff back in the basement onto the floor while it was still wet from remediating. That didn't sit right with me."

"Mr. Frank Trust and his employee, Toby, were prompt, extremely thorough, polite, professional and so considerate. Due to a leaking garage roof, mold and mildew developed and much of the stored items were destroyed. Mr. Trust and Toby spent about 7 hours cleaning, decontaminating and power washing the structure. They even cleaned, sanitized, wrapped and packed the personal items that could be saved. They did a fantastic job. Mr. Trust is a genuinely kind man. I’ve already recommended him to a friend. Thank you so very much for the service."

Mold Testing and Remediation FAQs, answered by experts

Visible growth, musty odors, and water damage are common indicators.

No, it isn’t. This is one of those things that needs to be dealt with immediately because mold will spread at a rapid rate and can go from just one spot on the wall to a serious health risk in a matter of days. Prolonged exposure can be extremely dangerous, so any mold issues (or even suspected mold) need to be dealt with right away. 

Mold grows in areas with humidity levels above 60%, but ideal conditions for mold growth occur when humidity is between 70% and 90%, especially in poorly ventilated areas. To prevent mold growth, aim to maintain indoor humidity levels between 30% and 50% using dehumidifiers, proper ventilation, and temperature control. Regularly check your home's humidity with a hygrometer to help you monitor and avoid conditions conducive to mold.

If your home was built before 1989 and still has original vinyl, there’s a high probability of asbestos mixed into the old flooring, which can harm you and your family if it’s disturbed from removal. If you suspect that you have asbestos, you’ll want to call in an asbestos removal expert to evaluate the situation.

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.
