"Have used HTI before and was familiar with their work. They did not disappoint as this was very hard needing encapsulation and numerous holes. Went from over 18 to less then .5pci/l over night. Made the whole basement smell better and they did a great job of hiding all the piping. By far the best out there and easy to work with. As honest as it gets. "

"Chuck Pacewicz performed a thorough analysis of our basement area and inspection regarding borderline radon readings. He was very patient and provided a complete and easy-to-understand description of what is required to mitigate the levels. I asked him several questions and he was very prompt with his responses. We signed a contract and will retest levels for verification before proceeding. I was very impressed with Chuck and recommend his services for any inspection issues."

"They were reasonably priced but I'd recommend skipping and saving yourself the heartache. I was having issues with the radon mitigation system they installed. After a few days of calling and leaving messages I had no response. Then we finally figured out when they installed the system it only received power when the light switch was on...instead of wiring it to run all the time. Still no response back from them and I am paying to fix the issue myself. Do not go with them."

We perform full service Mold remediation and ventilation. We can provide a quick inspection to check for mold and mold prevention. Mold Remediation Contractor Ventilation Ridge Vents Bath Vents Bath Fans

"Jon and his crew were absolutely amazing to work with! I was very pregnant/had a newborn for the duration of our house renovation and they kept me up to date every step of the way. They went above and beyond to fill in where needed and got things done quickly so that we could move back in with our baby. We hired them originally to help with mold remediation and ended up asking if they could do 5 or 6 additional projects, as they are skilled in many areas (putting up new drywall, stripping old wallpaper, painting, fixing a cracked basement beam, etc.). I would absolutely recommend them to everyone!"

Radon gas abatements FAQs

You need a professional radon test to determine if radon is present in your home or water. A qualified radon inspector can provide accurate measurements, costing between $150 and $800. This information helps you decide on the necessary steps to remove radon from your home when you hire a professional radon mitigation company.

Radon inspectors and radon treatment professionals have distinct roles. Inspectors measure radon levels and assess your home's risk, while treatment professionals install systems that reduce radon concentrations. In some cases, a single expert may perform both functions; however, each responsibility requires specific expertise to ensure accurate testing and safe system installation.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reduce radon levels reliably.
