"This job was completed efficiently and professionally. A design specialist came to test and measure every detail for the project. The crew arrived with everything needed for the job. They worked very hard to install Waterguard in the concrete floors inside around the foundation to the sump pump basket. They also installed Geo-lock anchors to support a block wall that was bowed. This company has 36 years in business and provides excellent results and professional customer relations. Call Amer. Wtrwrks for a free estimate. You will not be disappointed. A wise investment of $11,270."

"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."

Radon Detection and Reduction questions, answered by experts

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.
