"Robert explained a person who checks for mold cannot, ethically, remediate the mold. It would be a conflict of interest. I appreciated that information. He was thorough and explained what he was doing. Luckily, I did NOT have an air quality problem. I highly recommend his services."

"The team from Stay Dry was very professional. They were informative and transparent when describing what the work would entail and sent me pictures and updates throughout the day. They went out of their way to provide a thorough service. It is hard to know who to trust when having mold remediated because the levels of training and expertise are very different across companies. They are skilled and they care about the quality of their work and customer service. I will hire them again for the next project."

"I know that I'm being picky but there were a few paint splatters left behind. But it was ceiling work so splatters are probably expected. Other than that the work was good and I am confident no mold will return. The work was also quickly scheduled and finished quickly."

Mold Testing and Remediation FAQs, answered by experts

No—there are key things that help you determine if it’s mold versus mildew. Mildew is a specific type of mold. Both can trigger allergies, asthma, and respiratory symptoms, though mold is typically more severe than mildew.

A mold inspection costs an average of $660, with a typical range between $300 and $1,025. However, costs can be as low as $150 or as high as $2,800 depending on several factors. These include the size of your home, the type of mold, the extent and accessibility of the affected area, your location, and the number and type of samples required. Hard-to-reach areas like air ducts, crawl spaces, and wall cavities can increase the cost. Specific tests have different prices; for example, swab testing typically costs $200 to $300 per area, while more extensive air testing can range from $250 to $700. A thorough inspection is crucial for determining the scope of the problem and identifying the best remediation method.

It is safe to remove old linoleum, but it may require the help of a specialist due to the risk of asbestos in the material. Before you cut into linoleum or try to peel it up, have it tested for asbestos. If it tests positive, professionals will need to remove it to prevent the risk of health issues from airborne toxic particles. If it’s asbestos-free, DIY removal is possible and safe.

Many peel-and-stick wallpapers aren’t moisture-resistant, so if you install them in high-humidity rooms, mold can grow behind the wallpaper. It’s best to reserve peel-and-stick wallpaper for bedrooms, living rooms, and other rooms with lower humidity levels. Not only does this minimize the risk of mold growth, but it also keeps the wallpaper from bubbling or peeling.

Black mold appears in areas with constant moisture and has a slightly fuzzy texture. It’ll have a primarily circular pattern. While it’s known to have a black color, it can also appear dark green, or dark brown, although a few types include orange or white flecks. Identifying black mold is important because people who inhale the spores could suffer respiratory issues or neurological problems. Black mold is a toxic material and requires a professional to remove it.
