"Great customer service, working with Don, the owner. He is very professional and very thorough and makes you feel comfortable the whole time by giving you exact details of everything he is doing and price breakdowns as well which I really appreciate. I had to hire him for mold, remediation and air quality testing, as well as home inspection, and all of these jobs were thoroughly thoroughly detailed and I was highly satisfied. I would definitely hire him again."

"We had mold in our basement. Joel, of Quality Air, came to our home, inspected every room in the house, tested inside and outside, and gave us an assessment of the problem and an estimate of the cost. The extent of the mold required more mitigation than initially expected, but Joel worked with us on scheduling additional mitigation visits and did not charge more than the original estimate. Joel was professional, courteous and very easy to work with. We now have a safe, breathable basement. I highly recommend Quality Air for anyone with a mold problem."

"The tech who came out for test for moisture, Jared, was one of the best. Very friendly and very knowledgeable. He provided us with a lot of options. The company was very easy to communicate through e-mail and the entire project was quick. I reached out on Monday, they came by on a Thursday to test and came back the next Thursday and Friday to perform the remediation. Top notch!"

"On a whim I decided to check our radon levels in our basement. I guess I assumed this would have been done by the previous homeowner. Apparently one should never assume. My test game back at 5.9 pCi/L. The acceptable level is 4. And I wasn't going to chance my family's health. So I did my research on radon mitigation and sent a quote request through Angi's platform. I received a phone call the owner, John Spokis within 30 minutes on the Friday before New Year's. He explained the entire process and provided me transparent pricing over the phone and in writing via email same day. He was able to schedule us that Monday after New Year's. The installer Derek called me an hour before arrival to let me know he was on his way. He arrived on time, explained the work that was to be performed, reviewed the location with me and made sure I approved of everything before he started. The installation itself took about two hours. This included patching some cracks we had in our concrete at no additional charge. Frankly, I wasn't terribly excited about having a big white fan unit and pipe installed along my house. But I also knew that this was the optimal solution for our needs. And Derek took the time to make it look as neat and clean as possible. I really couldn't have asked for an easier or more pleasant installation at a very fair price. Oh and they guarantee after install that your radon will be 2pCi/L or below. They even give you a kit to test and make sure it has been lowered. There is a lifetime warranty on parts and labor that is transferable if you sell your home. And the fan has a 5 year warranty. So, if you have unsafe radon levels in your home. Don't procrastinate like I did. Just call Radon Systems and get it done in two hours. You'll be glad you did. I am."

Mold Testing and Remediation FAQs, answered by experts

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

Yes, mold can easily grow under your hardwood floors, especially if your house has recently flooded or if there is a leak from a pipe under the floor. Hardwood floors can trap moisture beneath them, creating the perfect environment for mold to grow. Similarly, mold can also grow under your wood floor’s surface paint.

You can do more with a home test kit than just check your water’s hardness. There are a few types of tests. The first one is simple and involves a strip that checks your water’s pH balance. The second and more thorough option is a master test kit, which shows your pH plus the presence of nitrite, ammonia, and other elements through color shades. Unsurprisingly, the most thorough test is one you send to a proper lab for analysis

You might be wondering, “Is laminate flooring toxic?” The product does contain formaldehyde, which is found in the resins used to bind the wood fibers together. But the chance of overexposure and adverse reactions, such as allergy- or asthma-like symptoms, is low unless you are exposed to formaldehyde in other places, i.e., if you work with formaldehyde regularly outside the home. Keep in mind, too, that many household products have the potential to pose a health hazard, such as cleaning products.

Seeing black dots around the air vents is alarming, but don’t worry. It’s probably just a build-up of soot and darkened dust. Soot is just a byproduct of burning organic materials, so it tends to form in the winter months.
