Why Hearthstone Chimney Co. Is New Milford’s Preferred Chimney Liner & Rebuild Company
New Milford homeowners don’t need a sales pitch. They need someone who shows up when promised, explains what is actually wrong, and fixes it without callbacks.
We’ve worked on chimneys along Kinderkamack Road, up near the high school, and throughout the neighborhoods off Henley Avenue for decades. Our technicians are background-checked, uniformed, and carry the equipment to complete most liner installations and partial rebuilds in one visit. That matters in New Milford, where many of our customers are retired or working from home and don’t want their schedules disrupted across multiple days.
Our Chimney Liner & Rebuild in New Milford reputation is built on documentation. Every inspection ends with photos you can see and a plain-English verdict - no jargon, no scare tactics. If the liner is sound but the crown is cracked, we’ll tell you. If the clay tiles are deteriorated and flue gases are leaking into the masonry, we’ll show you the camera footage and explain exactly what a stainless steel relining will solve.
Calls are answered by a live person 24 hours a day, 7 days a week. Not a callback queue. Not an app. A real person who can dispatch a technician to New Milford, usually same day or next day.
Our Chimney Liner & Rebuild Services in New Milford
Stainless Steel Liner Installation
For most New Milford homes with deteriorated clay tile liners, a stainless steel liner is the permanent solution. We size the liner precisely for your heating appliance - critical here because so many local chimneys were built oversized for oil burners and now serve gas equipment that produces cooler, more acidic exhaust. An improperly sized liner causes condensation that destroys masonry from the inside. We use DuraFlex and Olympia Chimney products, installed with proper insulation and connectors to meet current NJ chimney codes. Most installations along Boulevard and River Road are completed in four to six hours.
Flexible Liner Systems
Some of New Milford’s older colonials have offset flues or tight cleanout passages that rigid pipe cannot navigate. A flexible liner, properly insulated and correctly connected, follows the chimney’s existing path without breaking through walls. We’ve installed flexible systems in homes near the Hackensack River where the original construction left almost no straight vertical run. The key is using professional-grade materials - we source from Famco and Copperfield - not the thin-wall products sold online that fail within seasons.
Liner Replacement & Upgrades
When an existing stainless or aluminum liner has corroded, separated at the joints, or was never properly insulated, replacement is often more involved than the original installation. In New Milford’s 07646 zip code, we regularly find liners installed by previous owners that were never properly capped, allowing rain and debris to pool at the bottom. Our replacement process includes a full camera inspection of the remaining flue, removal of the failed liner, and installation of a correctly specified new system with a proper top-sealing damper or cap. We also handle Chimney Repair in New Milford when the masonry itself has been damaged by years of leaking exhaust.
Partial Chimney Rebuild
When the upper courses of brick are spalling, the crown is cracked through, or the flue tiles have shifted but the lower structure is sound, a partial rebuild preserves what works and replaces what doesn’t. This is common in New Milford’s postwar housing stock where the chimney exterior has taken forty or fifty years of freeze-thaw cycling without maintenance. We rebuild from the roofline up, matching existing brick where possible, pouring a new concrete crown with proper overhang and drip edge, and installing a new liner system sized for current appliances. The 90-Day Done Right Promise covers everything - in writing, no arguing.

Trusted Brands We Service in New Milford
We don’t substitute builder-grade materials to hit a lower price point. Our trucks carry DuraFlex stainless liners, HeatShield cerfractory resurfacing products, and Famco and Copperfield fittings and caps - the same brands specified by chimney professionals nationwide. For New Milford customers, this means faster turnaround because we don’t need to special-order basic components. When we inspect your chimney and recommend a liner system, the materials are already in stock or available within a day from our regional suppliers. No waiting two weeks for a box to arrive while your heating season starts.
Common Chimney Liner & Rebuild Problems We See in New Milford Homes
- Oversized flues from oil-to-gas conversions. New Milford’s postwar colonials and Cape Cods were built with chimneys sized for 180°F oil exhaust. Today’s gas appliances send cooler flue gas up the same shaft, producing acidic condensate that dissolves clay tile and mortar. We regularly find liners in homes near the high school that have deteriorated to the point of flue gas leakage into wall cavities.
- Shared flues with multiple appliances. A configuration we see constantly in 1950s-era homes off Henley Avenue: one chimney serving a gas furnace, water heater, and occasionally a wood-burning fireplace through thimbles added piecemeal over decades. This creates draft competition, backdrafting risks, and violates current NJ chimney codes. Our Chimney Liner & Rebuild team separates these systems with properly sized individual liners.
- Spalling crowns and freeze-thaw masonry damage. New Milford’s location in the Hackensack River valley means persistently higher humidity than surrounding Bergen County towns. That moisture wicks into mortar joints, freezes, expands, and pops the face off bricks - especially on south- and west-facing exposures. Late-fall inspection catches this before heating season loads stress the structure further.
- Unlined or partially lined original construction. Some of the borough’s earliest postwar homes were built with no liner at all, or with a partial clay liner that only extends partway down the flue. Building codes at the time allowed this; current NJ standards do not. We document the condition with camera inspection and provide a clear path to compliance.

Yes, we work throughout the 07646 zip code, from the neighborhoods along Kinderkamack Road and Boulevard down to the lower-lying areas near the Hackensack River.

New Milford pricing typically falls in line with Dumont and Bergenfield, slightly below Tenafly and Cresskill where taller chimneys on larger lots are more common. The biggest cost driver here is the borough’s concentration of postwar homes with complex shared-flue configurations that require more labor to separate and reline correctly.
