"It went great. I highly recommend them. They were a pleasure to deal with. The person that came out for the estimate answered all of my questions. The estimate was fair. The work was done on schedule and with no problem. At completion, everything was explained to me. I used their electrician which worked out fine. After completion the radon test showed that my level was now undetectable."

"We hired PureTech to advise us on a real estate inspection that included a radon test. That test came back over the safety threshold. After meeting with Zach C, he advised us to make some repairs in the basement and to schedule a retest. We did and the results speak for themselves; the levels came back well into the safe zone. I couldn't be more pleased with the recommendations made by PureTech and Zach C specifically. Saved us a bundle in what could have been a nightmare, and now the sale of our home can proceed. Thank you PureTech!"

"I very rarely write endorsements, but in this case, my experience was so satisfying that I felt an obligation to share. I have no connection to Marty, other than hiring him and his company, I have not been paid or discounted to write this and I never would sell my opinion. I had massive amounts of water leaking into my finished basement during the July 2017 record rainfalls. It wasn't the first time to get some water, but this was way more than normal. Carpet smelled really bad. I was sneezing and couldn't spend more than a few minutes downstairs to do my laundry. I contacted 2 contractors listed on Home Advisor. Marty from ATI called first thing the next day. He rearranged his schedule to see the damage after I told him I was anxious to get it fixed asap. He arrived on time and texted before he arrived. Very professional. Highly qualified. I was impressed with his scientific knowledge of the problem. He was NOT selling me on his services, he explained how the damage occurred, how to clean it up and what would need to be done to fix it. He discovered potential asbestos tile underneath the soaked carpet. I told him to take it all out and remediate mold and asbestos. I chose to forgo the prior testing to expedite the repair. He gave me a quote on site and I gave him a down payment. He and his employee, Wyatt, arrived 10 days later and worked more than 12 hours that day in hazmat suits and masks. The amount of work needed was unbelievable. They sealed off the basement with plastic and put up notices of the hazards. They came back another day to complete outside drainage of gutters. I asked about some other asbestos abatement and Marty prepared a proposal for exactly what I requested. I didn't hesitate to sign another contract for the additional work based on the quality of their work. I'm extremely pleased with their work and the results. I could add so much more to this review for all the things they did above and beyond the contract. One thing they did was to help move an old commercial oven from the basement when a buyer showed up in the midst of their remediation work. I thought the pricing was reasonable. The other quote I received was from someone who outlined a completely bogus remediation using essential oils and a $1000 fan. The other contractor told me he would not be wearing the hazmat suits and masks. That contractor's proposal was close in price to ATI, but I am certain the outcome would have been horrible. I spent $3250 on the first remediation and will spend another $4000 on the second part of the remediation."

"i checked out quite a few inspectors and was looking for not just a home inspection but also a radon test. this company had the best price on the combined requested services by a pretty decent margin. the report given was very detailed, with color pictures that was very well organized so it was easy to find and easy to understand. it was quite a few pages, which may discourage some, but if you want to know what you're looking at when purchasing a home, you'll appreciate the extra detail spent to get a large report. i was very impressed at how nice, and prompt it was because we were under some pressure with our closing date and he managed to get all this completed within just a few days. i was very thankful and appreciative for the services i got. give paul a call, he'll o right by you."

Radon Detection and Reduction questions, answered by experts

Mitigation reduces radon levels, protecting your health and complying with safety standards.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.
