"Chris & CJ from Stay Dry repaired a leak in our exterior gutter drain system that was originally installed by Stay Dry in 2021. They arrived on time and efficiently & neatly (had to dig to uncover about 12 ft of pipe) repaired the underground leak start to finish in about one hour, being careful not to damage nearby plants & flowers. This 5 star review is for Chris' & CJ's performance only. Cost is unknown as our condo assn would handle costs, if any. Should be zero as this should be warranty work."

"The crew took the time to answer my questions throughout my project. Including taking the time to send me videos of the progress in the crawl space as I do not go down there. The also we’re going to work to provide in house financing, although I did not end up using that service, it is nice to know they were going to work with me. My wife and I can already tell a difference in the air quality in the house. I would highly recommend the company and use them for future projects."

Mold Testing and Remediation FAQs, answered by experts

Slime mold will go away on its own within a few days to a couple of weeks. Generally, there is no need to use chemicals on this matter. If you want to get rid of it right away, rake over the slime mold and the surrounding area or hose off large patches of it.

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.

Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.

No, not all black mold is toxic. Although people often refer to stachybotrys chartarum as toxic black mold, there is little evidence that any one type of black mold has more toxicity than another. People who have an allergy to black mold would be more likely to have a dangerous reaction after inhaling it. Long-term exposure to black mold spores can lead to severe infection and disease. Some people only have minor health problems after black mold exposure. Ultimately, toxicity is rare with any kind of mold, but it is possible, so always take the appropriate precautions.
