Chimney sweep in Lynn, MA

Chimney care in the 781 area

Long heating seasons and repeated freeze-thaw cycles are hard on masonry around Lynn, Malden and Waltham. Water that soaks into a cracked crown or open mortar joint freezes, expands and breaks brick apart (spalling), and nor'easter rain drives water in at the flashing. An annual inspection before the first cold snap catches crown cracks and creosote build-up from a winter of wood burning.

The Census Bureau counts about 485,600 homes and apartments in the 781 territory. 72.5% were built before 1980 and 30.6% before 1940, close to the Massachusetts figure of 68.9% built before 1980. The median home here dates from the 1950s, and 55.1% of homes are single-family detached houses.

56.1% of occupied homes heat mainly with utility gas and 24.2% with fuel oil or kerosene. Wood is the main heating fuel in 0.2% of homes, lower than the national rate of 1.5%.

With 30.6% of homes built before 1940, many chimneys here are older masonry. Older flues can be unlined or have clay tile liners that have cracked over the years, which a camera inspection of the flue will show.

Under the 2021 International Energy Conservation Code, the territory is in climate zone 5A (cool, humid).
