"We hired Pure Maintenance of Colorado after another remediation company failed to properly contain mold during cleanup. Pure Maintenance was everything we needed — professional, knowledgeable, compassionate, and extremely thorough. They spent three full days deep cleaning, doing small-particle removal, and fogging the entire house and ventilation system. What truly matters is the outcome: the air in our home feels fresh and clean, and our child, who has mold sensitivities, has had no reactions since the treatment. The difference is night and day. We are sincerely grateful and give Pure Maintenance of Colorado our highest recommendation."

"Did you know mildew is the gas given off from mold?? Joe offered great advice about the growth of mildew into mold, and my landlord's responsibility to remove it. I feel that he is knowledgable and would perform a thorough inspection. Based on my present economics and quotes from 2 other firms, and not to discount Mold Testing CO at all, I decided on another company. Joe at Mold Testing CO is definitely my second choice."

Mold Testing and Remediation FAQs, answered by experts

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.

The easiest way to know if it’s a leak or evaporation that’s causing low water levels in your pool is by conducting the bucket test. However, you can also monitor the chemicals in your pool for signs of imbalances or conduct a visual inspection of the areas around your pool in search of excessive moisture or cracks.

Black mold and wood rot are both types of fungi that thrive in damp areas, but they are distinct issues with different consequences. Wood rot specifically refers to the decay of wood caused by fungi, which compromises the wood's structural integrity. Black mold, on the other hand, is a fungus that grows on the surface of materials, including both rotting and non-rotting wood. The primary difference is their impact: wood rot affects the wood's structure, while toxic black mold is a health hazard. Inhaling black mold spores can cause severe respiratory issues, whereas wood rot spores are generally not harmful to people. Because mold can grow on rotting wood, the two issues can be interconnected, but they are not the same.

Yes. Over time, hidden moisture from a leak in your bathroom may lead to black mold, requiring a mold remediation company’s services and the removal of large wall sections, which can be costly. For example, 100 square feet of drywall can cost as much as $400 to replace, while mold remediation can run anywhere from $500 to $3,000.

Yes, drywall mud can get moldy—though the presence of moisture is required for this to happen. That’s why the best way to keep your powdered drywall mud fresh for as long as possible is to keep it in dry storage conditions. If you live in a humid area, it might not make sense to stockpile a lot of powdered drywall mud before you’re ready to use it. As for premixed drywall mud, avoid opening the container until you’re ready to use it—and don’t expect it to last longer than six months.
