Sealing Air Ducts: A Comprehensive Guide for DIYers

Some homeowners opt for duct sealing as a DIY project. To get started, seal air leaks with putty or metal tape and insulate any ducts you can access (such as those in attics, mezzanines, unfinished basements and garages). We recommend using a putty sealer for the best results, as adhesive tape is not a durable option. Most people don't think about sealing their home's air ducts, but it is essential to maintain their home's energy efficiency. Once you know the process and have determined that duct sealing is the best solution for your home, you can decide whether to hire a professional or do it yourself.

Professional duct sealing companies use special technology to seal all duct connections from the inside. Generally, the best way to seal ducts is to hire a professional to internally seal the entire duct system. Having your ducts properly sealed will help you balance the air temperature in your home and improve air quality. Even perfectly sealed and insulated ducts lose some heating and cooling, especially if they are in unconditioned areas of the house, such as attics and mezzanines. According to the EPA, “about 20 to 30 percent of the air moving through the duct system is lost due to leaks, holes and poorly connected ducts.”If you are looking for more information on duct sealing for your home or business, contact Service Champions.
