"They were very nice and professional, but everything they said was wrong with the house I purchased, was wrong. Said there was a small gas leak on the water heater, spent $275 for a plumber to tell me nothing is wrong. They said the furnace was in good condition, but couldn't guarantee how long it would last because it was over 50yrs old. They were wrong again, there was a crack in the heater exchange, so unless we are a fan of carbon monoxide we can not use the furnace. So basically I paid $425 for them to turn things on and not actually inspect anything."

"Stacey and his son did a great job. He gave accurate advice and offered a solution and location for the system that was at a better price and place than I had been suggested by a competitor. The installation was done quickly, inconspicuously and well done. System lowered levels from high teens to less than 1."

"Bill was excellent! He was at the house when we arrived and was already walking and viewing the exterior. He was very knowledgeable, and patient in explaining what he was looking at and why. The house had some very serious issues that without his expertise, would have devastated us financially, down the road. We have used other inspectors in the past, but we will only call Bill at BC Warner Inspections from here on out!"

"It went very well! Tim came to the apartment and looked at the issue. He told me that he will place the order for the new and more efficient unit than the old boiler and install asap. Tim's crew came the following Monday to demolish the old boiler and installed the new boiler on the same day. The new boiler was up and running on the same day. It was a smooth startup!"

FAQs for radon gas testing projects in Dayton, OH

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
