"I monitored the radon in my house for about a month with a Radon Monitor made by AirThings. After a month, the average stayed around 4 pCi/L. I have a friend who recently had a radon reduction system installed in his house, so I asked who did the work for him. He told me that Radon Abatement Services did the work and that he could not have been happier with the work. He gave the owner's (John Swett) direct number. I called John and told him that I would like an estimate to have a radon reduction system installed. John immediately gave me the information that I needed to start the process. Within an hour, an employee (Nikki) called me and patiently, knowledgably, and professionally provided me with step-by-step instructions to get the ball rolling. Nikki is very responsive, and she follows through with everything she says she is going to do. I was provided an estimate, installation date, and within a few days I had a new system installed. The crew arrived on time and impressed me from the minute they got out of the truck. The team leader (Walter) knew me by name and introduced me to his crew. The crew is AMAZING! From start to finish, they respectfully treated my house as if it was theirs. Drop cloths were laid everywhere they were working. Walter and I walked throughout my basement, and he explained in great detail the extent of the work that he and his team would be performing. He explained the tests that he was performing (i.e. material under slab, air suction). Once he gathered the data he needed, he explained to me the entire process, and then he and his crew went to work. Walter is an expert through and through. Not just with his knowledge of radon abatement, but as a professional craftsman. The attention to detail, precise placement of all holes, piping, and electrical are very impressive. The efficient manner in how the job was carried out is second-to-none. The precision and amount of work that they accomplished in just under 4 hours is phenomenal. Since my basement slab did not have gravel underneath, the installation required two suction points. Walter's design, calculations, and fabrication of the two-suction system were brilliant. The work, both inside and outside, looks like a masterpiece. When the job was complete, Walter walked me to each portion of the job (inside and outside) to show and explain all aspects of the system. I'm 59 years old. During my lifetime I have hired many companies to perform a variety of services. Radon Abatement Services ranks in the top 5% of all companies I've ever hired. If you are considering getting a Radon Reduction System, or have Radon Reduction needs of any kind, LOOK NO FURTHER! Radon Abatement Services is the only place to go. The owner, employees, and services are beyond compare."

"After my basement test come back with significantly elevated radon, I contacted radon abatement services at the recommendation of a neighbor. A day and a half later, they were on site. While performing the initial walk through, the experienced and thoughtful professionals adapted their plan to utilize my sump pump. This was an effective strategy as it addressed the main source of radon and concealed the system in completely unfinished space. I just received my post mitigation radon results, and the system is working phenomenally. To sum it up, I was blown away by the responsiveness, thoughtfulness, and reasonableness and can't say enough positive things about this company. I don't ever post reviews, but in this circumstance I absolutely had to."

Hello my name is Jason William Hornung. Buying a home is a big investment. I want to help you make a well informed decision. I have been in the residential construction field for 17 years, and have an intimate knowledge of the homes in our area having done so much work in them myself. I stay continuously trained studying current information to give the best reports out there. I've seen many things that other inspectors have missed both as a home inspector and a contractor. My inspections meet or exceed the ASHI standards of practice. WWW.Homeinspector.org/standards WWW.JWHInspections.com

"The work has not yet been done - scheduled for two days from now. Very pleased with the estimate and service to date. The work has now been completed. An excellent job configuring the stacks to be as unobtrusive as possible, sealing cracks and floor drain, and installing a radon flow alarm. An independent radon test has been scheduled now that the work has been finished. Excellent company. Highly recommended."

"I was very pleased with the service and work done by SWAT environmental. Lance was very helpful in explaining the process when he booked my appointment and the two techs who installed the radon remediation system were professional and courteous. The system itself isn't inconspicuous but I feel safer knowing that our radon levels are significantly lower now."

Radon Detection and Reduction questions, answered by experts

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

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.

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.

Yes, many systems include warranties for performance. Confirm terms with your installer.

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.
