Freeze-thaw cycling is the governing condition. Water that gets into masonry, grout or a roof detail expands when it freezes and widens the gap it entered through.
Creosote is what burns in a chimney fire. Third-degree creosote is glazed and hot enough to crack flue tile, and removing it is the entire point of an annual sweep.
Most chimney leaks are not the brick. They are a failed crown, missing cap or bad step flashing where the stack meets the roof - which is why repointing a chimney that leaks through the crown fixes nothing.
What the job includes
- Annual sweeping and creosote removal
- Level 1 and Level 2 inspections
- Stainless cap and crown repair
- Flue liner installation
- Flashing and leak repair
- Dryer vent cleaning

Winters are long: the Manchester Ap station averages 129 nights a year at or below 32°F and 52 at or below 20°F.1,2 In long winters, chimneys work hard and masonry sees many freeze-thaw cycles; annual inspection and a sound cap and crown are the maintenance baseline. The median home in the town of Derry was built in 1983, newer than the U.S. median of 1980 and newer than the New Hampshire median of 1979.3 Derry's housing is newer than the national mix: 40% of units predate 1980 against 50% nationally, and 5% date from 2010 or later.3
Rainfall is substantial: about 40 inches a year, 8 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. Heating dominates the year: about 6,172 heating degree days against 773 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.
