Brooklyn’s summer heat and humidity are tough on older brick chimneys, especially in homes built before 1980. We’re seeing more calls for liner checks and masonry repairs as moisture and heat stress the mortar. Book a free estimate today if your chimney’s over 10 years old.
Why Brooklyn’s summer weather hits older chimneys hardest
Older brick masonry in Brooklyn homes wasn’t built to handle today’s humidity swings. When temperatures spike, mortar joints expand and contract, cracking faster than in drier climates. Add summer storms, and water seeps into those cracks, freezing in winter and widening them. We’ve had three calls this week alone in Park Slope where homeowners noticed white efflorescence—salt deposits from dissolved mortar—on their chimney crown. If your chimney’s over a decade old, a chimney inspection should be on your summer to-do list. Ignoring it risks water damage to your flue liner, which can lead to carbon monoxide leaks.
Should I check my chimney now or wait for fall?
Don’t wait for fall’s first cold snap—Brooklyn’s summer humidity is already doing the damage. If your chimney’s brickwork looks uneven, the mortar’s crumbling, or you spot rust on the damper, call us now. We’ve seen too many homeowners in Ditmas Park regret skipping summer maintenance when their liner failed during a winter storm. A quick DIY inspection can spot surface issues, but a pro should check the flue and liner. We’re booking summer appointments now—don’t let a cracked liner turn into a costly repair.
