We are certified by the NEHA (National Environmental Health Association) through the National Radon Proficiency Program. This is your assurance that our company has demonstrated knowledge of radon mitigation techniques and follows proper protocol. We are also licensed by the State of Connecticut to perform radon mitigation for both air and well water. In addition, we offer various water treatment technologies to improve your drinking water.

We do not claim to be the largest or oldest mitigation company in Connecticut, however, we are confident that our quality and service is second to none. In fact, we were the first in the Connecticut market to advertise “satisfaction guaranteed” … since then our competition has followed our lead.

Customer service is paramount. HSW Radon Contractors, LLC is committed in providing the most effective, reliable, and affordable systems that exceed customer expectations. Each system is thoughtfully laid out and installed with fine workmanship. Your satisfaction is always guaranteed.

Whether you need a new installation, a repair/modification to an existing system, or simply would like to order a radon test/water analysis, please give us a call.
