"Basement Doctor work crews were prompt and polite, accommodated my requests, and cleaned up beyond my expectations. There were, however, significant problems. Estimate was incomplete -- need for dehumidifier was not emphasized until after the work was in progress so was not in the contract. Cement dust was bad enough to injure my lung. However, Basement Doctor made what seemed like reasonable effort to contain the dust. The same might have happened no matter who did the work. After phase one was done, there was dampness along the crawlspace wall where drainage had been installed. I was told that it was not wet. In order for it to be wet, there had to be standing water. When examining the conditions in order make an estimate for phase 2, my project manager looked at the crawlspace drainage that had been installed in phase 1, he saw something that caused him to call the production manager, then told me that there was a problem with the drainpipe as installed in phase 1 and that it would be replaced in phase 2. This left me with worry about whether the rest of the work had been done correctly. When phase 2 was complete, I expressed disappointment that the appearance of the encapsulation did not live up to expectations. Primarily, the taped joint between the material used on the floor and part way up the wall and the silver insulated material used on the was not level, and was wavy to an unsightly extent The white material billowed out from the wall into the floor space rather than going down the wall consistently then out onto the floor. The project manager said that Basement Doctor guaranteed the function of the work, not its appearance. The foreman said that the white material would, over time conform to the wall. (It hasn't.) The project manager said the production manager (director?) would call me. It took three months and a nasty letter from me for that call to be received. When he came to my home the production manager reiterated that Basement Doctor stood behind the function of their work, not its appearance -- at least for the type of work done in my home. He said that there had been no problem with the drainage pipe that had been replaced, but that it had been replaced at my request. At that point I wondered who I should believe. He did improve the appearance of the encapsulation by adding tape so the joint was no longer wavy."

FAQs for radon gas testing projects in Newark, 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.
