"Dave was extremely helpful in giving grounded, low cost solutions for my ongoing mold issue. Proving sound and reliable advice in a sea of so much overwhelming information was invaluable. He took the time to look over a previous report that provided misguided information and recommendations and took the time to walk me through the correct steps saving me so much time and headache. Thank you so so much. I highly recommend this company for their mold services and consult."

Mold Testing and Remediation questions, answered by experts

Yes. Musty smells in your home usually signal that mold or mildew is lurking somewhere. Both can cause allergy symptoms in those who are allergic. Mold can cause structural damage and serious health issues if left unaddressed.

If you're wondering about black stains on brick at your home, the answer is that you're not looking at efflorescence. While efflorescence can be darker when certain types of salt are involved, black staining is caused by carbon staining, pollution from vehicles, and chimney soot. Black stains can also be caused by organic materials like lichen, algae, or mold.

Mold can begin to grow in as little as 12 to 24 hours, especially if the room is warm, so drying the area is the first thing you should do after water damage. Because mold and mildew can cause a range of health issues, make sure you clean up any water damage as soon as possible and run blower fans and dehumidifiers for 24 to 72 hours to dry out the room and reduce the risk of mold growth.

No. When dry, mold enters a dormant state. While “sleeping,” the mold won’t multiply, but when it encounters moisture again, it springs back to life, releasing spores. That's why it's crucial to not only control humidity but also actively eliminate mold to prevent its resurgence and further growth inside your home.

Toxic drywall has a sulfur smell, similar to rotten eggs or poop. It’s often a sign that the drywall mud is expired, there’s mold or mildew growth, or there’s a leak in your home. Drywall can also absorb moisture during storage, transportation, or installation, resulting in a distinct musty odor.
