Berkshire Radon LLC does radon mitigation. Its Massachusetts home improvement contractor registration, number 197899, is active on the state registry, with Berkshire Radon LLC as the holder of record. A recent customer said Justin fixed their radon problem during a two-and-a-half-hour visit and left the place looking better than before. A recent customer said the company gave a fair quote quickly and did the work quickly with no mess. A 2025 customer said Justin confirmed their radon levels were elevated with his testing equipment and installed a radon vent, and that their levels were below.5 pCi/L afterward. That 2025 customer also said Justin measured a nearby family member's home at over 150 pCi/L and fit in a vent installation there quickly. A 2023 customer said Justin first recommended a solution that came in under budget and, when the system needed to be expanded, returned and completed the added work under his original estimate. A 2019 customer said Justin explained up front what the work would cost and how the system would be installed.
If I could give a bazillion stars, I would! Justin is awesome and did a super amazing job. He made two and a half hours fly by in what seemed more like thirty minutes. The guy is just that good at what he does. He fixed my radon problem for me instantaneously and also located my missing keys at the same time. He is super cosmic. Hire him now and you will have virtually no problems for the rest of your days. He also has class, he doesn’t spit or smoke and he left the place looking better than before. I would recommend him to the queen and king of the universe, and they’d call me personally to thank me for it. Thank you Justin!!! Much appreciation!!! A gajillion stars on everything! 😎🙏✨💫🌟🌟💫🌟💫💫⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️🌟⭐️🌟⭐️🌟⭐️✨✨💫✨💫✨💫💫💫⭐️💫⭐️💫⭐️🌟🌟⭐️🌟⭐️💫💫💫✨💫💫💫✨✨✨✨
Gave a fair quote quickly. Scheduled and performed the work quickly and efficiently. No mess no hassle, what more can you ask for. A plus contractor
Justin is great to work with. We had an issue with our radon level and reached out to Berkshire Radon for some help. He was responsive and easy to communicate with. Once Justin confirmed our levels were elevated with his testing equipment, he made a plan to address it. Installation of a radon vent was clean, relatively quick and painless for us, even with little kids and multiple dogs at home. Results were almost instant, and our levels are below .5 pCi/L now. We then had him measure a family member who lives very close to us and the levels were over 150 pCi/L, which is significantly higher than they should be. He squeezed us in very quickly for a vent installation, knowing that the family member wouldn't be comfortable living in their home now that they knew how bad it was. 11/10. Would recommend Justin to anyone who needs radon help.
We worked with Justin at Berkshire Radon and from our first call during the home inspection process all the way through the actual work, he was incredibly helpful and responsive. Being cost-conscious for his customers, Justin recommended we try an initial solution that would come in under budget to first see if that would effectively lower the radon levels. When we ultimately needed to expand the system, Justin promptly returned to our home and completed the additional work under his original estimate. Justin is a pleasure to work with and I highly recommend anyone needing radon mitigation to use his services.
We had a great experience with Justin at Berkshire Radon. He was very quick to respond to us each time we contacted him which we really appreciated. He helped us feel comfortable knowing up front what things would cost and how it would be installed. He was also thorough and thoughtful with how he placed the system in our house which we were grateful for. We're so glad we found Justin and recommend him to anyone else looking to have radon mitigation done!
