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 has grown, we have since expanded our services to include removing moisture from homes. This moisture is the main reason mold forms in attics. Hot attics cost money in engergy costs and other issues. 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 up to date research, contact with ventilation product manufacturers, ventilation seminars and product research.

We deliver attic ventilation presentations to a wide variety of industry and consumer groups and associations throughout the New England area. We have hundreds of satisfied customers, with references 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.
