"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."

"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 />"

"Gary, the install tech, was great. He arrived on time, was professional, and went above and beyond to ensure everything was done right and I was satisfied. He installed a new radon pipe, and ensured the clamps were not directly against the house and the top of the pipe was properly away from the gutter. After the pipe was installed I noticed a rattling noise coming from the motor...Gary checked it and cleaned out debris multiple times until the noise was gone. You could tell Gary takes pride in his work and wanted to do the job right the first time (I feel like you don't see this very often). A job well done."

"Overall A+ experience from start to finish. Terry replied to my email and voicemail promptly as well as explained the scope of his work. On the day of inspection, I arrived 15 minutes early and found Terry was already busy working; inspecting and talking pictures of the outside structure and front yard. After a few minutes of observing him, I felt very good and confident that I picked the right person for the job. This was the guy who really knew what he’s doing and paid attention to all the details. As a female who didn’t know anything about home maintenance and improvements, Terry explained everything to me patiently and answered all my questions. He pointed me to issues that needed to be addressed soon and things that I needed to keep an eye out as well as some basic maintenance. The property had a finished basement and I’m glad that Terry had an infrared sensor to check for heat loss and moisture; those issues might not be visible because the basement wall was finished/painted. <br /> I chose Radstar Radon Monitor to eliminate the wait. Both home inspection and radon result were delivered promptly via email. I’m very satisfied and highly recommend Seacoast Inspection. <br /> <br />"

"We live in a townhouse condominium and are not allowed to make any modifications on the exterior, which is frankly, the easiest way for a radon mitigation company to do their job quickly. No problem at all! The owner John came to our home to do the evaluation and provide an estimate. He’s been doing this since the 90’s and knows his stuff! It was easy peasy and we booked our work for a couple weeks out. The technician, Bryan (who's also been doing this since the 90's!), arrived promptly at 8am, as scheduled and set to work. He was very professional and patient with me, a DIYer with a ton of questions. His work is impeccable. Honestly, I wasn’t sure what to expect and was very nervous about the whole thing, especially since he had to go through several floors inside a couple of closets and my new hardwood floors. He was so accurate and efficient that I actually didn’t know he’d gone through the floors and ceiling until I saw the holes. They were neat, no jagged edges, no damage to the floors or ceiling. I was shocked – in the most positive way. I can’t recommend this company highly enough. I’ll use them for any home I ever have and recommend them to everyone I know!"

"MKC made the whole home inspection process extremely easy.  We needed to have an inspection in a short timeline (we were calling Thursday for the following week) and contacted MKC after reading reviews here and on Yelp.  MKC was able to accommodate this short timeline by scheduling us for the following Monday at 9:00 am. <br /> While our realtor had recommended other inspectors and MKC's price was a slightly higher than others, I was very happy we went with MKC.  We worked with Morgan, who was extremely thorough, detailed, and professional.  He was very attentive to all aspects of the house (from small items such as dishwasher positioning to larger drainage issues) and explained everything to us in detail.  He also took his time to check everything carefully, rather than rush the process, while taking thorough notes and photos.  The end result was a detailed and clear punch list report, which he prepared within 24 hours. <br />   <br /> We had planned to perform a radon test that day as well but unfortunately were unable to do so because of the amount of work still in progress on the house. We plan to have Morgan back both for the radon test and to check the results of the work on punch list items. <br />"

FAQs for radon gas abatement projects in Westwood, 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.
