"The professionalism and work performed were fantastic...The work was performed in a timely manner, and everything was cleaned up when it was completed. Everything was explained to us in detail as to what we could expect from your work, and we were not disappointed. The retesting revealed that the radon in the air and water were below normal and the exterior of the house was minimally effected. Thank you again for doing such a quick and great job!"

D & M, Southbury, May '10

"Thanks for completing our recent mitigation project. It was done in a very professional manner and Ken was available to answer every question we had. We were very pleased with the work as well as the outcome. He was able to reduce the radon to below 1pic/L. We would recommend it to anyone whom needs this kind of service; quick, reliable, efficient and affordable."

Maria, Southbury, April '10

"I recently had a radon in water reduction system installed by HSW. All my questions were answered promptly prior to purchasing the product. The installation work was neat, concise and carried out as according to plan. The results of my re-tested water far exceeded my expectations."

Sue, Oxford, April '10

"We were very pleased with all aspects of our radon mitigation system, from the quotation process, to scheduling and installation...The install itself was very clean, with no dust or debris afterwards, and high quality workmanship ... the follow-up air test came back at less than 0.4 pc/l, quite an improvement over the 6 to 11 pc/l levels before the system was installed. Thanks for a job well done!"

Mike, Southbury, March '10

"Thank you for all the effort you put into correcting this problem for me. I’m very happy that you were able to find the cause and correct it. I will certainly keep you in mind for any future work that I have done in this area. It’s difficult to find people who show up when they say they will, stick to their estimates, do what they say they will do and see the job through to completion in a timely manner. You’ve exceeded my expectations. Thanks again."

Jesse, Harwinton, December '09


"We are very happy with the work Ken and HSW did. They were very prompt, came the same day to take a look at the basement, and installed the system a week later. Our radon went from over 40 to 2 pCi/l. The system is quiet and less ubstrusive than I thought... and there was no clean up at all. The whole process was quicker and easier than I expected."

George, Southbury, August '09

"Dealing with HSW was a pleasure. Ken was extremely knowledgeable, professional, and more than willing to answer questions and explain what he was doing and why. The radon system that was installed cut the level down to almost zero. I recommend HSW to anyone who needs radon mitigation."

Jim, Middlebury, August '09

"In the midst of selling our townhouse we needed to fix our current radon remediation system to satisfy our buyer. We were under a very strict time constraint and HSW acted as quick as we could ask. The work performed was impeccable, done within one day, and post install tests confirmed the quality. My agent and I will be sure to recommend HSW to everyone we know."

John, Danbury, July '09

"I'm extremely pleased with our radon system (water)...workmanship is nothing but of the highest quality. Ken was both personable and professional and addressed any concerns or questions I had. I highly recommend using HSW Radon Contractors for your mitigation project. You will not be disappointed."

Tony, Harwinton, May '09

"You did an excellent job. It was very professionally done, well placed and well executed. Best of all, the results in my basement went from 27 to 0.4 ...Thank you."

Joe, Woodbury, October'08

"...we were pleased with the rapid scheduling you offered us, given the concern of radon exposure to our new baby girl! Also, the job was finished entirely in 2 days (water and air systems), which had no interruption of our life/home. The products were top of the line, the communications you gave us regarding the systems was clear from our first consultation, through the work, to finish when you explained the workings of the products & the expected lowered radon findings post-installation ... We could not be happier with our decision to use HSW & have already recommended your services to several of our friends."

M&J, Woodbury, September '08

"Finding high levels of radon in our water, especially during the sale of our house, was a stressful situation. Ken did an outstanding job minimizing our stress and costs as well. Not only was he able to come see us the day we called, he gave us a very reasonable estimate on the spot. More importantly, he recommended just addressing the water radon first, to see if that reduced the air radon... Upon retesting the fix for the water radon, our air level was fine. He saved us nearly $2,000 by his advice. When it came time to do the work, he was on time, did a fantastic job and his estimate was right-on. Overall, we could not be happier with Ken and HSW! I would give them my highest recommendation!!!!"

Bob, New Hartford, August '08

"We had HSW Radon Contractors install our recent mitigation project. It was done in a very professional manner. We were very pleased with the work as well as the outcome. We would recommend it to anyone whom needs this kind of service."

Marge & Bob, Wolcott, August '08

"...the Radon mitigation system met my expectations very well. The work was performed on time, the areas were left clean and the work appears to be of very high quality. I appreciated the flexibility with the installation schedule. Since we were relocating, scheduling was tough and you worked with me very effectively. Two added benefits that I did not expect, but were very welcome, was the potential for reduction in water acidity and the increase if home water pressure...

Craig, Woodbury, July '08

"It truly was a pleasure having your company and you remediate our problem. Your response was immediate, your workmanship professional, and your concern for our situation genuine. Thank you for your prompt, courteous service.

Michael, Torrington, June '08

The HSW experience was beyond any expectations I had for a contractor installation. Ken was superbly businesslike and accommodated my unique needs as executor to my Mom's estate. He saved the sale of the estate home and I am forever grateful to Ken and HSW."

Ron, Torrington, May '08

"I wanted to thank you for a most professional and successful execution of our radon mitigation project. I would highly recommend your services to anyone requiring or desiring such work."

HSW Radon takes every step possible to provide you and your family with the highest quality of materials and protection from radon. They are courteous, clean, and always on time. As a builder, I would highly recommend HSW Radon Contractors to any individual or home builder."

Curt, Construction Mgr. at Nation’s leading builder of luxury homes, Newington, February '08

"... the work you did for me was better then expected. The radon report I got back from the radon test after you completed your work at my house was less than 1 pCi/L (originally ~ 79 pCi/L). I'm very pleased with your fast and efficient work and wouldn't hesitate to recommend you."

Art, Wethersfield, January '08

"In the process of selling our home, we were shocked and surprised that our buyer's home inspection revealed a high level of radon gas in our home (>10pCi/L). Mitigation of this problem was a critical contingency for the sale of our home and we had to resolve it quickly... Ken at HSW Radon Contractors was by far the first to respond and he provided a reasonable written quotation within hours. Ken installed the mitigation system in a professional, courteous, neat and efficient manner several days later. The system reduced the radon level in our home to less that one-tenth of the pre-mitigation reading and along with HSW's 5 year warranty to ease our buyer's mind, the transaction for the sale of our home closed without a hitch."

Ken, New Milford, December '07

"As a real estate professional I must be confident in those contractors to whom I refer my clients. After all, my reputation is at stake. When my clients' home was recently tested for radon and the results were not favorable, they naturally looked to me for advice. Because of your superb work ethic, reliability and honesty, I immediately asked them to call you. Your prompt service, professional manner, and realistic quote put them at ease. They were shocked when you completed the task within a week of your visit. I was not. This is what I expected from you. Thank you once again for another job well done."

- Mary Ellen, Real Estate Agent, Burlington, December '07

- Ram, South Windsor, August '07

"We are very satisfied with the radon abatement work that you did for us back in July 2007. You were professional, reasonable in your pricing, and very neat in your job performance. Your follow-up on your work was very reassuring to us. We no longer have a radon problem and for that we are extremely grateful. We would not hesitate to recommend you to anyone who has a radon problem and in fact we have done so on many occasions. Our son was extremely pleased with the work you did removing the radon in his water supply".

-Bob and Anne, Watertown, August '07


"Ken's service was very important to close the purchase of my current home. During the inspection process of the home I just bought Radon levels in the water showed very high levels. I contacted HSW to get an estimate to solve the problem while I negotiated with the seller. Ken helped me with estimates, retest and finally installing a remediation system that satisfied both the seller and myself. During the whole process Ken was always courteous, available and flexible for coming to the site. He was also excellent providing explanations and offering advice over very specialized issues. I strongly recommend HSW if you have a radon problem".

-Julien, Weston, July '07
