"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

Yes, both mold and mildew can grow under outdoor rugs if they are exposed to water or humidity for a prolonged period of time. This is why frequently cleaning an outdoor rug and checking its state is important.

Powdery mildew tends to grow mostly on leafy plants. The mold itself isn’t particularly harmful, except for those who are allergic to mold. However, you should treat it like you’d treat the discovery of any other mold, and get rid of it immediately. Powdery mildew can spread to your home, which can cause expensive damage. 

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.

Knowing what to expect during a mold inspection can help make the process easier. Prepare by closing doors and windows for 48 hours, turning off HVAC systems for at least two hours, and avoiding disinfectant chemicals for at least 48 hours. 

The mold inspection process takes between 24 and 48 hours. Your professional will check walls, fireplaces, air ducts, vents, and windows for visible spores. They will also take an outdoor base air sample. Your pro will send these samples to a lab for testing and advise you on the findings.

Just because you find mold in your home does not mean you need to pursue professional remediation services. You can often clean small amounts of surface mold, such as in bathrooms or on windowsills, using household products. However, extensive mold growth, persistent odors, or mold caused by water damage require professional remediation. A good rule of thumb is to hire a pro when the mold is in an area larger than 10 square feet, poses health risks, or affects the structural integrity of your home.
