RadonGuys/Chapin Environmental Company History
Chapin Environmental was opened in 1989 by John and Scott Chapin. The original office was located in Johnston Rhode Island and they served both the Eastern Massachusetts and Rhode Island areas. In 1992 the office was moved to Holliston MA to be closer to the majority of our customers.
In the early 2000's the company became known as "RadonGuys" and this website was launched. With the addition of email and mobile phones RadonGuys became more versatile and began to spend more time in the field supporting our thousands of customers and their installed radon systems.
In 2017 James Duffy became the principle owner of RadonGuys. With a promise to continue the quality work that RadonGuys is known for, Jim looks forward to serving Massachusetts communities and meeting their radon remediation needs.
