How to Seal Leaky Ductwork | Ask This Old House

Richard Trethewey shows an innovative new way to seal ducts from the inside. (See below for steps.) SUBSCRIBE to This Old House: http://bit.ly/SubscribeThisOldHouse Richard uses a new technology to seal ducts from the inside. Steps for How to Seal Leaky Ductwork: 1. Remove the grilles from all of the supply and return registers. 2. Plug each duct register with foam rubber and wide strips of tape. 3. Pressurize the duct system with a blower fan. 4. Use a computer to analyze the data to determine the amount of air leaking from the ducts. 5. Use the blower fan to mist the inside of all the dust with liquid-rubber sealant. 6. The sealant will find and plug all air-leaking holes, cracks, and seams. 7. After applying the sealant, run another pressurized blower test to verify the improved results. Richard demonstrated sealing ducts using the Aeroseal System [https://aeroseal.com/]. Expert assistance with this project was provided by Boucher Energy Systems [https://boucherenergy.com/].
