Chimney Sweeping & Repair in Elsmere, DE

The Wilmington New Castle Co Ap station averages 92 nights a year at or below 32°F and 21 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 town of Elsmere was built in 1956, older than the U.S. median of 1980 and older than the Delaware 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.

Rainfall is substantial: about 45 inches a year, 12 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 20 inches a year.^1,2 Snow sitting against the stack keeps masonry wet for weeks; a cap, a sound crown and sealed counterflashing are what keep it out.

Heating dominates the year: about 4,647 heating degree days against 1,228 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 Elsmere are normally issued by the town building department.^4,5 Where a liner or rebuild needs a permit, the contractor files it with the city before work starts.
