VentMASTER Attic Ventilation Solving Heat, Mold, and Ice Dam problems

About Us

 VentMASTER was established in 1990 to identify and solve a wide variety of attic problems. We began creating ventilation solutions mainly for excess attic heat and ice dams, but as the need has grown, we have expanded our services to include addressing and removing moisture problems from homes’ interior spaces as well.

Our services are recommended by a number of Microbiologists and mold remediation companies (a list is available upon request). We provide our customers with cutting edge attic ventilation techniques by utilizing the latest research, contact with leading edge ventilation product manufacturers, and product research.

We regularly share our 30+ years of expertise by delivering attic ventilation seminars to a wide variety of industry organizations, consumer groups, and associations throughout the New England area. We have hundreds of satisfied customers, with references are available upon request.

VentMASTER does not perform mold testing or mold remediation services. However, we can recommend several excellent companies that have long records of mold testing and remediation services.

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