Aeroseal Tech specializing in Aeroseal Technology and other ways to improve Air Quality, Air Volume and Velocity for residential and commercial buildings. We take on jobs ranging from simple to complicated and perform all work with the utmost attention to detail and customer service. This way we are able to achieve the best results for our customers which we guarantee for 10 years! Aeroseal Duct Sealing is a patented breakthrough technology that tackles leaks from the inside out. Aeroseal software allows the technician to accurately measure the duct leakage in residential homes and commercial buildings. The Aeroseal process puts escaping air under pressure and causes polymer particles to stick first to the edges of a leak, then to each other until the leak is closed. The technology was developed within the Indoor Environment Program at Lawrence Berkeley National Laboratory, whose IAQ scientists tested it. The research was funded by US Environmental protection agency, US dept. of Energy, Electric Power Research Institute and California Institute of Energy and Environment. The University of California was granted initial patents in 1996 and 1999, and Aeroseal holds an exclusive license to the technology.
