With Knoxville’s August heat and humidity, older brick and masonry garage doors take a beating. Sullivan W. Garage Door’s Repairs Inc. urges homeowners to inspect hinges, liners, and weather seals now—before cracks or misalignment turn into costly repairs.
Why Knoxville’s August humidity is brutal on vintage garage doors
Knoxville’s late-summer humidity swells wood frames and warps metal tracks, while brick and masonry garage doors often develop hairline cracks in mortar joints along Kingston Pike or in older neighborhoods like Bearden. These small gaps let in moisture that rusts springs and seizes rollers—especially in homes built before 1980. Sullivan W. Garage Door’s Repairs Inc. recommends checking weather seals and liners now; a quick replacement of worn seals can prevent water damage that leads to costly brick masonry repairs.
What Knoxville homeowners should test before Labor Day weekend
Start by running a full cycle with the door closed—listen for grinding or uneven movement that signals worn rollers or misaligned tracks. Next, inspect the brick facade for loose mortar near the lintel above the door; Knoxville’s older homes along Sutherland Avenue often show early wear here. Finally, test the auto-reverse safety feature by placing a 2x4 on the floor—if the door doesn’t stop and reverse within two seconds, it’s time for a safety inspection. Sullivan W. Garage Door’s Repairs Inc. offers free estimates and serves all of Knoxville and nearby areas like Farragut and Sevierville.
