"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."

"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

Touching toxic mushrooms will generally not cause harm unless you consume them. It's important to thoroughly wash hands after handling any type of mushroom to prevent accidental ingestion.  

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.

Fiber cement siding is resistant to mold and mildew, so it won’t be as affected by these problems as something like wood siding. However, damage to your siding or improper installation can still lead to water getting behind your siding, in which case, mold can grow behind it and damage other building materials. Contact a siding repair professional if you suspect you have a leak.

Figuring out why you have a musty smell in your house is the first step to getting rid of it. Mold or mildew is most likely causing the unpleasant odor. People use these terms interchangeably, but they’re actually different.

Mold is a fungus that loves to grow in moist, humid places. It’s typically black or green and has a raised, uneven texture. Stay vigilant for signs mold may be growing in your home. 

You’ll find mildew growing on your shower walls and in your bathroom’s nooks and crannies. It’s a specific type of mold that grows flat. Mildew is usually white, gray, or yellow.

Some causes of brown well water—like excess tannins or dissolved iron—don’t pose a health risk. In other cases, harmful bacteria might be the culprit. If your well water has suddenly turned brown, it’s a good idea to use a home water test kit to get a better sense of what’s going on with your water. Consider calling a professional for an expert opinion before drinking the water and hoping for the best.
