Chimney Sweeping & Repair in Knoxville, TN

The Knoxville Mcghee Tyson Ap station averages 67 nights a year at or below 32°F and 10 at or below 20°F.^1,2 Repeated freeze-thaw cycles open small masonry cracks; an inspection should include the crown, the cap and the condition of the flue tiles. The median home in the city of Knoxville was built in 1974, older than the U.S. median of 1980 and older than the Tennessee median of 1987.³ Older masonry chimneys may be unlined or have cracked clay tile liners; a Level 2 camera inspection is the standard way to confirm the liner before the first fire of the season.

Somewhat more of Knoxville's housing predates 1980 than the national share: 59% against 50%, with 11% built since 2010.³ Rainfall is substantial: about 52 inches a year, 14 days of it an inch or more.^1,2 Heavy rain tests the flashing and crown; most chimney leaks enter there rather than through the brick, and the inspection report should say which. Snowfall averages about 5 inches a year.^1,2

Heating dominates the year: about 3,528 heating degree days against 1,574 cooling degree days (base 65°F).^1,2 In a heating-led climate, insulation and air sealing carry most of the energy-code weight for any work that opens the envelope. Building permits in Knoxville are normally issued by the city building department.^4,5 Where a liner or rebuild needs a permit, the contractor files it with the city before work starts.
