"I had a problem with the water pressure fluctuating. Come to find out, it was the holding tank. The professionals at Waterdrct came out (Dennis) promptly and found the tank was old and waterbound. They were like lightening (in a good way) and had the tank replaced in like 30 mins. These guys are GOOD !!! The water pressure was more than I thought the well could produce. Excellent job and very informative. They are true professionals !! I highly recommend them."

"In late October, when outside spore counts are almost as high as in September, PureOne completely emptied, scrubbed, and disinfected my basement and garage. Two years prior, I had had a water event, when a flooded kitchen wet down part of the basement. The remediation was completely effective, judging by a subsequent air quality test. The basement spore count fell from 4,461 to 66. Special thanks to Joe, O.B., Damyon, Kyle, Ben, and Alysia."

"This review is from a seller where an inspection was performed. The heat was not shut off after the inspection and my family and I walked into 90 degree temperatures because the heat was never turned off when the inspection was complete and it was on for 7 hours until we got home. In addition the mud room has a thermostat and electric heater and that was also left on high which we did not realize until the next day. In addition, to prove a point to a potential buyer he forced a hole through the wood in our detached garage reporting that there are signs of water damage. The garage is from 1930, there has been water in the garage especially when we had the hurricane last year but they could have just written that in the report not damage our property to prove a point. Coincidentally, the same inspector came back with another interested buyer and yet another piece of wood was pulled off from the garage. If that is not bad enough, the same inspector gave confidential information from a previous inspection to a new potential buyer which led to another buyer terminating the deal. I know this as our lawyer communicated with the potential buyers attorney and said that the inspector passed on information about a previous inspection he did at our house a week earlier.. in addition, our neighbor and friends were outside during the outside portion of the inspection and they heard the inspector give the potential buyers and their real estate broker information about the last inspection and what the other potential buyers said. So much for confidentiality."

FAQs for radon gas testing projects in Sterling, CT

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.
