"They responded quickly to my inquiry and were very informative. They were able to address my mold problem within a week. I chose Mold One because they only needed a half day to address my problem and they did not need to tear out walls and other affected items. Our basement/workshop was full of stuff which we did not have to remove. When finished the moldy odor was absent from the basement. Their price was considerably lower than that of conventional remediators. Their warranty is for one year and I am hoping the process holds up as promised."

"They were quick and thorough and knowledgeable and tested air inside and out and then recommended mediation. They don’t do that so there’s no conflict of interest. They recommended a company but left it up to me."

Mold Testing and Remediation FAQs, answered by experts

Poor maintenance can cause some health concerns, although these are more common in commercial misters than residential versions. For example, stagnant water can become a breeding ground for bacteria, some of which can be dangerous to human health, especially when inhaled. Regular flushing of the system before seasonal use should prevent issues like these.

Otherwise, avoid using mosquito misters with pesticides or plant misters with fertilizers near humans. These misters are not designed for cooling sprays around decks or patios, but for more utilitarian purposes.

The best way to measure moisture levels in drywall is with a moisture meter. Moisture meters feature small probes that you insert into drywall (similar to pushing a pin into the wall). Ideally, you'll take moisture readings at several locations on the wall to get a general idea of the moisture level.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

Mold inspections are worth it because they can catch troublesome mold problems early before they get out of hand. It's worth it to address mold problems as soon as possible because mold can be hazardous to your health and cause damage to your home and its belongings. Mold testing and inspections are the best way to know if you have a mold issue in your house.

Yes, mold can grow on nonporous surfaces. Mold is extremely resilient and can survive just about anywhere. However, mold will not grow as quickly on a nonporous surface as on a porous one. Additionally, the nonporous nature makes it easier to remove. Keep the countertop clean and properly maintained, and you shouldn’t experience mold growth.
