Above all, we are watchful of our customers' interests and make their concerns the basis of our business.

"We had our radon fan replaced by Radon Bros in January 2025. From the beginning, the new fan was noticeably louder than the previous one. At that time, the technician advised us that the increased noise was due to the fan being stronger than our prior unit. Over time, the fan became increasingly louder and ultimately stopped working in early December 2025. When a technician returned to replace the fan, we were informed that the fan originally installed was defective and that Radon Bros had stopped using that manufacturer due to known issues. Despite this, we were charged a $99 labor fee for the replacement. We do not understand why we were responsible for this charge when the failure was due to a defective fan that your company was already aware of and no longer installs. We felt we had no choice but to pay the $99 in order to have our radon mitigation system restored and functioning properly. "

Quality Workmanship, Problem Solving Solutions, Works With You In Planning, Designing And Staying Within Your Budget

"Our HOA hired Gary Nolder to repair and renovate our 2BR 1BA unit that had succumbed to uneven flooring over the years and a flooded kitchen. From the start, Gary seemed perfect, attentive and detailed with great designs. However the second he received the money is when the problems. Coordinating with Gary became slower due to his frequent vacations and inability to get ahold of him several times over 3 months. We had to reach out to his subcontractors and he scolded us for doing this! The cardinal sin is that Gary's team either purposely choose to not level the flooring substrate by simply adding new subfloor on-top of the old structurally problematic base, which would have kept the problem unresolved! We and our HOA ended up breaking ties and cutting our losses with him, very sad because we lost countless weeks with him. We don't recommend Gary to anyone."

"The self-test product was as expected. The reports require additional research to interpret and understand, so seemed more targeted at professionals."

FAQs for indoor air quality testing projects in Northumberland, PA

You should test your home's air quality if you or your family experience health problems like allergies or respiratory issues, as these could be linked to indoor contaminants. Also, consider testing if you're concerned about mold, radon, carbon monoxide, or if you've recently had home construction, demolition, excavation, or remodeling that could have released chemicals into your indoor air.

An indoor air quality test typically takes one to three hours to complete. After the inspection, you'll receive a detailed written report within two to 10 days. The evaluation includes comprehensive air sampling from all designated areas in your home. Your specialist will review the findings with you and provide clear guidance on steps to take if any issues are found, helping ensure your indoor environment meets health and safety standards.

A certified indoor air quality consultant or inspector is the right professional to perform your indoor air test. While some home inspectors have certifications, they often subcontract this specialized work to trained professionals with advanced tools. This expert will thoroughly evaluate air samples from every area in your home and clearly explain the findings to you. Be sure to confirm your tester's credentials before scheduling your service.
