Air sealing is the systematic finding and sealing of air leakage points in a home or building. Electricians, HVAC contractors, and plumbers will drill and saw their way through floors, walls, and ceilings, creating channels for the wires, heating ducts, water lines, and waste pipes that need to be run throughout the house. While these penetrations in the building envelope do not compromise the building’s strength, they result in air leakage that can make the building inefficient and uncomfortable.
Air sealing reduces drafts and heat loss by eliminating air leaks in the building around the chimney, plumbing penetrations, and recessed lights. Our experts use a variety of materials, including caulk, spray foam, metal flashing, weather stripping, and rigid foam. Some materials are more suitable than others for specific locations or trouble spots. For example, fire-rated caulk and metal flashing are used in high-temperature situations like around the chimney. This one-time process effectively seals for the lifetime of the building and is one of the most cost-effective means to ensure a home is energy efficient.
Air sealing is one of the most inexpensive strategies you can employ to help you save money on your utilities and feel more comfortable as soon as it is completed. Not only does the process help lower your utilities and make the home comfortable, but it can also help improve the air quality inside the home, help prevent moisture problems and prolong your HVAC system.
