"Fast response to inquiry. Flat rate fee and was able to schedule the work within 7-10 days. The installer was on time, finished on time and was very professional. Site was left clean and tidy. Retesting after 5 days had reduced the radon to below 2. The install worked great and as they warranted it would."

"Airtight did a great job from start to finish. Pre-mitigation testing showed radon levels ranging from 3-12 pCi/L, with an average above EPA recommendations. Accurate estimate, explained every step along the way. The actual job was complete in less than a day! Radon levels taken through the pilot holes were through the roof (150 pCi/L for one hole, average of 118 for all pilot holes)! Now the levels average at 1.7 pCi/L over a three day period, with only a single data point hitting 3. I highly recommend Airtight Radon Solutions, LLC for radon mitigation!"

"I hired Erickson Foundation for radon mitigation. Job went smoothly. They communicated well, were very professional, and reviewed all potential options for the job with me. The system installation was done on time, professionally done, and well cleaned-up. The equipment is high quality, with the 10-year warranty being a big plus."

"A and R Environmental was recommended to us by friends who have a construction business. They did not disappoint! <br /> Jordan came out to install a radon air system in the house we were in the process of purchasing. He was right on time and was very kind and professional. He determined where the best place for the system would be so it would not be intrusive and would be inconspicuous. He worked very diligently in order to finish without taking up a lot of our time. He did a beautiful job. Once it was done he set up a radon test and came back a few days later in order to check to make sure the system was working properly, which it was. <br /> We had a choice of several companies to use, most of which were less expensive, but we decided to go with A and R because of their good reputation, warranty, and professionalism. We highly recommend them. <br />"

"First off - DO NOT DO PAY FOR THEIR WATER AND RADON TESTS!  They are over-priced and take way too long for results.  In fact we never received our water report!  Do it yourself, get tests from a reputable and more reasonable lab, such as www.etrlabs.com/ in Leominster.  We paid PC&A almost as much for the tests as the inspection and didn't have results within a week! <br /> PC&A also are pretty big on CYA, so don't expect too much out of the inspection report.  They were very good one-on-one during the inspection.  Although they pulled the classic 'get there 30 minutes early and do the roof first'.  When you arrive on time they will tell you 'oh, we did the roof first and found this and that', but they won't take you up there.  This is annoying, if you are going to buy a house, and pay for an inspection, and the roof isn't crazy steep or high, then you MUST walk the roof.  Preferably aided by a professional who can walk you through the various issue.  In our case the roof had all sorts of problems.  I didn't get a clear idea what they were based on the inspection and report and therefore had to pay a roofer to come out and walk me through the problems.  So I paid twice! <br /> All the negatives aside, we really did find the remainder of the inspection helpful, both the inspectors were knowledgable and responsive to questions, and brought issues to our attention.  We did not end up purchasing the house, based in part on issues uncovered during the inspection, so it wasn't a total waste of money.  When we did find the right house for us, we had a different inspector and did the water/radon tests ourselves.  In total it came in $450 less than with PC&A and the inspection/report was just as good, plus we had our inspection and tests results emailed to use within 48 hours. <br />"

"Showed up on time, performed a nice clean install, explained the whole system, and sealed off my sump pit. Very informative, professional and prompt. They offered a $100 discount for referral that I got from my real estate agent, and I could not have been happier with the work."

"The design that was proposed at the initial visit for the estimate ended up being problematic when the technicians came to do the actual installation. It was only with my help that they were able to solve the problem. I was convalescing from knee surgery so it was somewhat inconvenient for me to have to get up and out to figure out the situation. It ended up all right in the end; they did good work with no mess. The post-installation test confirmed a significant reduction in the level of radon gas in the basement of our house."

FAQs for radon gas abatement projects in Still-river, MA

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
