Your information is kept private and used only for your chimney service request.

Sweep & Cleaning
Chimney Cleaning
For older Bergen County chimneys, the cleaning is paired with a close look at the tiles the soot has been hiding all winter. Creosote, soot and ash removed from the flue, smoke shelf and firebox — the deep clean that kills the campfire smell and the fire risk with it. That local standard is what chimney cleaning in Demarest, NJ means with Chimney Service Co.

Install & Replace
Chimney Cap Installation
A quality stainless cap keeps rain, birds and sparks where they belong. Fitted to your flue, secured properly, and screened against animals. Around Demarest, caps are secured against winter storm winds, because a cap lost in January leaves the flue open to every thaw.

Repair
Chimney Liner Repair
Cracked tiles, gaps at the joints, a liner that is shifting — liner faults found on camera and repaired so hot gases stay inside the Demarest flue where they belong. A tight liner also restores draw, so some smoking fireplaces in older homes trace back to tiles, not the firebox. Chimney Liner Repair in Demarest, NJ runs on one standard: done properly, checked, and shown to you before we leave.

Winter in Demarest 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.
Colonial, Victorian and early suburban homes give Demarest 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.
Coastal storms drive rain and wet snow sideways at Demarest chimney tops, tear at caps and soak crowns that are already cracked by freeze-thaw. After a big storm, the cap, crown and flashing all deserve a look before the next fire gets lit.
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 Bergen County that has had one needs a full camera inspection before it is used again, without exception.
Where salt air reaches Demarest - 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.

Usually a cold flue. A tall masonry chimney in Demarest 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.
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 Bergen County we inspect the entire flue after any chimney fire and report exactly what is damaged before anyone burns again.
Yes - in many Demarest 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.
Often ice and flashing working together: ice dams push meltwater against the chimney, flashing loosened by freeze-thaw lets it in, and saturated brick passes it through to the wall. The stain shows by the fireplace, but the repair belongs at the roofline and the crown, in that order.
Late summer or early fall, before heating season. Every neglected chimney in Bergen County seems to surface the same week in October, and that is when schedules fill. A sweep and inspection in September means your first fire is routine instead of a gamble on an unchecked flue.
No — and be wary of anyone who does. Every chimney fails differently, so a phone price is a guess that changes at your door. Our estimates are free: a tech looks at the actual problem, then gives you one clear price before any work starts.
