"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."

"They were quick and thorough and knowledgeable and tested air inside and out and then recommended mediation. They don’t do that so there’s no conflict of interest. They recommended a company but left it up to me."

"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."

"We were selling our house and the radon test came back high so we needed quick and effective service. The appointment was scheduled a week from our call. The technician arrived on time and helped identify the best location for the system that was both effective and as aesthetic as possible. The install went quickly and he took the time to explain how it worked and what we should look for in terms of monitoring and maintenance. Overall, it was a good experience."

Mold Testing and Remediation FAQs, answered by experts

If you notice increased energy bills, poor airflow, or frequent HVAC system issues, a professional assessment is advisable. Technicians can identify duct leaks or inefficiencies that require updating or maintenance.

Results typically come back within 48 hours, allowing for prompt remedial action.

The spread of wood rot results in a physical breakdown of the wood’s cellulose and lignin, causing it to become spongy or brittle. This can lead to structural damage. Water won’t damage the physical structure of the wood, while mold can eat away at the material and cause structural damage over a much longer timeframe. When further considering water damage versus mold versus wood rot, all three issues can create a musty or damp odor in the area. All three can also cause discoloration of the wood.

There are different types of mold, and not all humans are the same. For example, a more toxic type of mold may have less of an effect on a healthy person than a less toxic mold in the home of someone who is immunocompromised. If you recognize any symptoms of mold poisoning—sinus issues, brain fog, respiratory distress, constraint cough, migraines, or any others—call your doctor or go to the hospital before you attempt any removal.

Yes, carpet mold can spread if not addressed properly or quickly. Mold can spread to underneath the carpet, impacting the subfloor or attached walls. Mold and mildew can spread within the first 72 hours, so it is important to address the problem quickly and remove any affected carpet.
