Winter in Dunellen 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.
Ice dams at the roof edge push meltwater under shingles and against chimney flashing all winter in Middlesex County. The leak that shows by the fireplace in February often starts at frozen flashing, not the flue - and it returns every thaw until it is fixed.
Colonial, Victorian and early suburban homes give Dunellen 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 Jersey 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.
A chimney fire can crack flue tiles and warp metal liners without leaving much evidence in the room - the fire burns up, not out. Any chimney in Middlesex County that has had one needs a full camera inspection before it is used again, without exception.

Once a year at minimum for a fireplace in regular use - and after about every cord of wood burned, whichever comes first. Dunellen fireplaces work for months in a cold flue, and creosote builds steadily the whole season. The sweep and inspection together are the safety check.
Serious enough to fix before another winter. Mortar is the sacrificial layer that keeps water out of the brickwork, and freeze-thaw in New Jersey 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 before a full camera inspection. Chimney fires crack tiles, warp metal liners and open mortar joints, often with no sign visible from the room. In Middlesex County we inspect the entire flue after any chimney fire and report exactly what is damaged before anyone burns again.
Yes - in many Dunellen 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.
