Family owned business since 1982 and 2016 Angie's List Super Service Award winner. All long term employees, no salesman and the two owners are on every job. We do not sub-contract unless it is a field of expertise outside of our field of business. We do offer financing and payment plans.

"The entire experience, from start to finish, was a pleasure, which we were not expecting. From the time Curt came out to take a look at our issue, from the time the team was wrapping up the work, everyone was extremely professional and friendly. We always heard from Curt when he said we would hear from him, and the team on-site was a hard-working group of professionals. The quote from Real Dry was about 3k less than competitors. There were no high-pressure sales tactics, and no surprise add-ons to the quote. And the work they performed is top notch! They did a fantastic job and they will be my go-to company for any services they offer. We are very happy with the entire experience!"

Soil, Water & Air Technologies provides solutions to customers in need of vapor intrusion services. We custom design sub slab depressurization systems to effectively mitigate radon gas, TCE, petroleum vapors, and various other VOC's. Most real estate transactions, financing and/or re-financing activities require an environmental review which includes air quality testing. Our experienced office staff understands the need for quick, complete, and accurate information in order to provide solutions so transactions are not put at risk. We offer detailed upfront pricing, best in class warranties, and proudly offer discounts to senior citizens, service members and repeat customers.

"Be careful. I called to have a radon mitigation system installed and the sales rep on the phone took down the information and scheduled the appointment. I was upfront about an interior drain being installed. When the technician arrived, he said he'd be happy to install the system, but that it would be worthless because of the interior drainage system. I then received a $200 invoice for the site visit. Frustrating scenario to have a sales rep schedule the appointment, knowing full-well that I had an interior drain, and then the technician tell me there's no point to install a mitigation system, but then charge me for the inconvenience of it all."

My goal is to educate as well as inspect. I will walk through the home in your presence and examine each system. I treat your new home like a big book, and we will turn the pages together so by the end of the inspection, you will know as much about your new home as I do. I then write a comprehensive, narrative report complete with color photos that is emailed to you that evening. I also offer follow up consultation for any report I write.

"Chris arrived early, well before we did (and we were early!), to start inspecting the exterior of the property. He explained up front what he could and could not do. In the process of the inspection he explained what he was looking at, the reasons for looking and what he might have found and then what he did find. We had lots of questions but he also repeatedly asked us if we had more questions. We feel that we have as good a grasp of what the pros and cons are about this new (for us) house as we can. The report is thorough (with pictures) and he will be sending us a bound copy that we expect will be our house book/bible from here on. We felt like we were his only concern. He had no skin in the game on whether we bought the house, his only concern was to educate us."

FAQs for radon gas testing projects in South-wellfleet, MA

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.
