The Georgetown TX Difference in Duct Sealing
Georgetown attics regularly reach 130 to 150 degrees Fahrenheit on a July or August afternoon, and every seam, joint, and connection in your duct system sits inside that heat for months at a stretch. Unsealed or poorly sealed ductwork does not just leak air, it leaks conditioned air into that superheated attic space while simultaneously drawing hot, dusty attic air back into the return side through the same gaps. That two-way exchange is why sealing pays for itself faster here than in milder climates. The Department of Energy estimates typical homes lose 20 to 30 percent of the air moving through the duct system to leaks, and in a Central Texas summer that lost air is some of the most expensive air a home produces.
We seal ducts using one of two methods depending on the joint type and access. Mastic, a paint-like adhesive compound, goes on with a brush at every metal-to-metal seam, collar, and boot connection, and it stays flexible for decades without the cracking that eventually affects tapes. For factory seams on rigid duct board and for connections that need to be serviceable later, we use UL 181 rated foil tape, which is a mesh-reinforced tape rated for HVAC use, not the cloth duct tape sold at hardware stores, which fails within a year or two of attic heat cycling. Every seam gets pressure tested informally by feel and, on larger jobs, verified with a duct blower test that measures cubic feet per minute of leakage before and after sealing.
The most commonly missed leak points are not the obvious ones. Return plenum seams, the connection where flex duct meets a metal collar at the air handler, and the boot-to-drywall interface at each register are where we find the largest single leaks, often larger than all the small gaps in the trunk line combined. A full sealing job typically covers the accessible trunk line, all boot connections, and the return plenum, and runs from about 300 to 800 dollars depending on the size of the duct system and the number of leak points found. Homeowners typically notice more even room-to-room temperatures within the first cooling season after sealing, along with a reduction in the fine dust that settles on furniture when the return side has been pulling in attic air.
