In a continued effort to help our customers achieve better indoor air quality our mission is to provide quality duct-cleaning utilizing advanced cleaning equipment and procedures. Through the use of the Wolverine Robot duct cleaning and inspection system and the “Source Cleaning Method” we can obtain results unmatched by traditional methods. The Source cleaning method is the physical removal of dirt and debris from the air ducts using mechanical agitating devices such as pneumatic powered brushes or air activated air whip hoses that are passed through the ducting while the air handling system is under HEPA filtered negative pressure. The use of HEPA filtered negative pressure and zone bags controls the movement of the dust while cleaning to prevent contaminants from entering the living space. As opposed too old methods when the majority of the work was performed from the exterior of the ducting. While using the Wolverine robot we are able to inspect the inside of the ducts through a video camera installed on the robot. This allows us to determine the appropriate scope of work, as well as making the cleaning process much easier and provides a video documentation of cleanliness (where accessible). GB Environmental has been involved with indoor air quality since 1990 when it first started doing asbestos abatement projects. In 1998 GB added mould abatement to its portfolio of indoor air quality concerns. Now after more then 1000 projects from a team with more then 50 years experience, GB has added duct cleaning to the services we offer our customers. We feel that with our experience, dedication and understanding of indoor air quality, GB Environmental will be able to excel at providing quality services to our customers.
