VentMASTER - We Fix problem Attics -781-643-7501

About Us


VentMASTER was established in 1990 to inspect and provide ventilation solutions for a wide variety of attic problems. We began venting mainly for excess attic heat and ice dams, but as the need grew, we expanded our services to include removing moisture from homes. In early 2020, after 30 years of fixing problem attics, we decided to focus solely on attic inspections. We now use our expertise to provide our customers with the information they require to find issues and the best ways to solve them.

Please note that we will be happy
to contact you Monday through
Friday from 9:00 AM – 5:00 PM.
