"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."

Mold Testing and Remediation FAQs, answered by experts

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

The gasket and drum of a washing machine are ideal spots for mold to grow. They are dark, warm, and humid, conditions that mold thrives in. The products you use to wash your clothing, such as fabric softener and detergent, can also encourage growth by giving the mold a food source.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

Not all molds are inherently harmful, but their presence can lead to health issues, especially for individuals with allergies or respiratory problems. Black mold often garners attention due to its potential toxicity. However, other molds can cause health concerns too. Regular mold, appearing in various colors like green, gray, brown, or black, can trigger allergies and respiratory problems. Prompt removal and prevention measures are essential, regardless of mold type, to maintain a healthy indoor environment.

Yes, mold can grow in a wet dryer vent. Mold is a type of fungi, and fungi thrive in warm, moist conditions. Dryer vents need to be aired out so heat can escape and moisture can dry. If your dryer vents aren’t properly vented, the trapped heat and moisture will cause mold to grow, and the mold can spread to the dryer and even your clothes. Not only can this leave a musty smell on your freshly laundered clothes, but—more importantly—it also poses a health risk.
