Winter in Larchmont is long and hard, the housing stock is old, and many chimneys predate modern liner standards entirely. This is what we actually find here, and what we check on every visit.
Water enters mortar joints and crown cracks across Larchmont, freezes hard, expands and pries the masonry apart a little further with every cycle. By late winter the evidence is spalling brick, open joints and leaks that were hairlines back in the fall.
Colonial, Victorian and early suburban homes give Larchmont some of the oldest chimneys in daily use - hand-laid brick, clay tiles, fireboxes built before modern codes. They reward careful inspection and punish shortcuts, and we report honestly what is sound and what is not.
Some older New York chimneys were built with no liner at all, and others carry liners that stop short or crack at the joints. Hot gases and sparks reach mortar and framing through those gaps, so the camera inspection comes before the first fire, not after.
Where salt air reaches Larchmont - the shore towns and harbor neighborhoods - stainless caps, dampers and liner tops corrode years faster than they do inland. The failure is quiet: a seam opens, rain follows, and the flue starts taking water every storm.

Serious enough to fix before another winter. Mortar is the sacrificial layer that keeps water out of the brickwork, and freeze-thaw in New York opens failed joints fast once they start. Repointing sound brick is a repair; waiting until bricks loosen and shift turns it into a rebuild.
Not until a tech has seen how extensive the cracking is. Tiles are the barrier between hot gases and the masonry and framing behind them, and hard freeze-thaw cracks them in most older Larchmont chimneys eventually. Many cases call for liner repair or relining, which is a real fix.
Usually a cold flue. A tall masonry chimney in Larchmont holds heavy cold air that pushes down until a fire warms the flue, so the first minutes spill smoke. Creosote narrowing, a stuck damper or a missing cap make it worse. We check the whole path before suggesting fixes.
Yes - in many Larchmont homes the furnace, boiler or water heater vents through its own flue in the shared stack, and oil and gas liners crack, soot up and block with age. A blocked appliance flue can spill exhaust indoors, so we inspect every flue in the chimney.
