Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Liner & Rebuild Across Paterson
A typical chimney liner replacement in Paterson runs $2,800-$4,500, while a partial rebuild of a spalled crown or upper stack costs $1,800-$3,200. Most jobs are completed in a single visit after our Level 2 camera inspection confirms exactly what needs doing. If your Paterson row home has an original coal-era chimney venting a modern gas furnace or boiler, the flue is almost certainly oversized, unlined, or both, and that mismatch is the root cause of most draft failures and moisture damage we see.
We’ve been working on chimneys in Paterson for decades. Our crews know the difference between a 1890s silk-mill-era triple-decker on Broadway and a 1920s two-family on East 18th Street, and we know how the Passaic River valley wind patterns affect draft in taller stacks. Dispatch and scheduling are coordinated from our New York City office, but our technicians live and work in northern New Jersey, so we’re not learning your neighborhood on your dime. When you call (973) 604-2986, a live person answers, 24 hours a day, every day.
Why Hearthstone Chimney Co. Is Paterson’s Preferred Chimney Liner & Rebuild Company
Paterson homeowners have long memories for contractors who oversell or disappear. We’ve been serving local communities for over 42 years, and we plan to be here in thirty more. That changes how we treat every job.
Our Chimney Liner & Rebuild team documents every inspection with photos you can see and a plain-English verdict. No camera evidence, no recommendation. In a city where one chimney breast often serves multiple households across property lines, that discipline matters more than anywhere else. A cracked liner in your unit can vent carbon monoxide into your neighbor’s flue, and an unscrupulous sweep can use that fear to sell work neither party needs.
We back every liner and rebuild job with our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork to dig up, no arguing. Our technicians are background-checked, uniformed, and carry professional-grade materials from brands like DuraFlex, HeatShield, and Gelco on every truck. Most jobs finish in one visit. The number on your upfront estimate is the number on your invoice.
Calls are answered by a live person, 24/7. Not a callback queue, not an app.
Our Chimney Liner & Rebuild Services in Paterson
Stainless Steel Liner Installation
For most Paterson gas furnace and boiler retrofits, we install a DuraFlex stainless steel liner sized precisely to the appliance’s BTU output and venting requirements. The original coal-era flues in Paterson’s row homes are typically 8×12 inches or larger, while a modern 80% efficient gas boiler needs a 5- or 6-inch round flue to generate enough velocity to carry exhaust up and out. Dropping an oversized flue without a liner guarantees condensation, freeze-thaw spalling, and eventually carbon monoxide spillage. Our stainless liners come with a lifetime warranty when properly maintained, and we seal the top with a Gelco or Famco termination cap sized to Paterson’s wind exposure.
Flexible Liner Installation
Some Paterson chimneys have offset flues, narrow cleanouts, or structural obstacles that make rigid stainless tubing impossible to fish through. For these, we use a DuraFlex flexible liner that navigates offsets while maintaining the smooth interior surface exhaust needs. Flexible liners are especially common in the older three-story row homes near the Great Falls Historic District, where chimney runs are long and often dogleg between floors. We always perform a camera inspection first to map the flue path and confirm a flexible liner will draft correctly for your specific appliance.
Liner Replacement
Clay tile liners from the 1920s crack, shift, and spall with age, and in Paterson’s freeze-thaw climate, the damage accelerates. A cracked clay liner in a party-wall chimney is not merely a maintenance item. It’s a shared carbon monoxide pathway. We remove deteriorated clay tile in sections, drop a new stainless or flexible liner, and seal the smoke chamber and thimble with HeatShield refractory mortar. The old flue becomes a structural chase; the new liner handles exhaust. This preserves the masonry while solving the safety problem, which matters in historic districts where exterior alterations face scrutiny.
Partial Rebuild
When the crown, upper courses, or shoulder of a Paterson chimney have spalled beyond sealing, we rebuild with matching brick and proper crown slope to shed water. Northern New Jersey’s freeze-thaw cycles destroy flat or improperly sloped crowns, and Paterson’s exposed brick stacks suffer more than most because the original coal-era construction used softer, more porous mortar mixes. We form a concrete crown with minimum 2-inch overhang and drip edge, flash the chimney-to-roof junction with copper or lead, and guarantee the workmanship under our 90-Day Done Right Promise. A partial rebuild typically addresses the top 3-6 feet of stack and crown, preserving the lower structure when it’s sound.

Trusted Brands We Service in Paterson
We stock professional-grade liner and rebuild materials from Olympia Chimney, Famco, and Copperfield on every service truck, so most Paterson jobs don’t wait on parts. Olympia Chimney’s stainless liner systems carry UL listings for both gas and solid-fuel venting, which matters in Paterson’s mixed housing stock where some units still burn wood or have pellet stove inserts. Famco termination caps and draft-inducer fittings handle the wind channeling that comes with Passaic Valley geography. Copperfield supplies the refractory cements and smoke chamber sealants we use for HeatShield applications. We don’t substitute builder-grade materials to hit a price point. The liner is buried inside your chimney where you can’t see it, so its quality matters more, not less.
Common Chimney Liner & Rebuild Problems We See in Paterson Homes
- Oversized unlined flues condensing moisture inside the stack. Original coal-era chimneys in Paterson’s 1885-1935 row homes were built to vent high-temperature, high-volume exhaust from coal stoves and furnaces. Modern gas appliances produce cooler, wetter flue gas that never warms the oversized flue enough to maintain draft. Moisture condenses on the brick, freezes during Passaic Valley cold snaps, and spalls the interior from the inside out.
- Party-wall flues creating cross-property carbon monoxide hazards. In Paterson’s attached row homes, one chimney breast commonly serves flues for two or three adjoining units across separate property lines. A liner cracked in one unit leaks exhaust into the shared masonry cavity, and that exhaust can enter the neighbor’s flue. Neither household realizes the problem until a CO alarm sounds, and neither owner wants to pay for a repair that benefits both.
- Chronic downdraft from flue gas volume mismatch. A gas water heater producing 35,000 BTU routed into a flue sized for a 150,000 BTU coal boiler simply doesn’t generate enough buoyancy. The exhaust stalls, reverses, and spills back into the basement or living space. We see this constantly in Paterson’s converted two- and three-family homes where the original chimney was never resized for modern appliances.
- Spalled crowns and eroded mortar from freeze-thaw exposure. Northern New Jersey’s winter temperature swings, combined with Paterson’s aged, porous brick and original lime-based mortars, destroy chimney crowns and upper joints faster than in newer construction. The Passaic River valley also creates localized wind patterns that drive rain into crown cracks that would drain dry in calmer locations.

We were called to a three-story brick row home on East 18th Street where the gas-fired boiler was spilling exhaust back into the basement. A Level 2 inspection with our camera showed the original coal-sized flue had no clay tile liner at all, just eroded mortar joints and a cracked smoke chamber, and the run was shared with the neighboring unit’s water heater flue. We dropped a DuraFlex stainless liner sized to the boiler’s BTU output, sealed the smoke chamber with HeatShield, and rebuilt the spalled crown. Draft readings normalized and the CO alarm stopped tripping.

FAQs - Chimney Liner & Rebuild in Paterson
The liner serving your appliance is your responsibility to maintain, but the masonry chase containing both flues is typically a shared structure with joint liability for structural integrity. In Paterson’s attached housing, we document which flue serves which unit with our camera before any work begins, and we flag cross-leakage between flues that creates a carbon monoxide hazard for both households. If shared masonry needs repair, we provide a written report both owners can use to coordinate cost. Call (973) 604-2986 for a free inspection and documented findings.
Your chimney was designed for a coal-burning appliance that produced exhaust at 600°F or higher, and the flue is probably 8×12 inches or larger. Your gas furnace produces exhaust at 300-400°F with much lower volume, so the flue never warms up enough to create upward draft. The exhaust stalls, cools further, and sinks back into your basement. A properly sized stainless steel liner fixes this by reducing the flue diameter to match the appliance’s output, creating the velocity needed to carry exhaust up and out. We see this exact pattern on virtually every residential block in Paterson’s older neighborhoods.
Clay tile from the 1920s has served its design life and is almost certainly cracked, shifted, or spalling in Paterson’s freeze-thaw climate. Even intact clay tile was never tested or listed for modern gas appliance exhaust, which is wetter and more acidic than coal flue gas. The National Fire Protection Association recommends a listed liner for any appliance connected to a chimney. We don’t recommend replacement without camera evidence you can see, but in Paterson’s housing stock, the camera almost always shows deterioration that warrants a liner. Call (973) 604-2986 for a free Level 2 inspection.
Our Level 2 inspection camera shows the interior surface of every flue tile joint, the condition of mortar between tiles, cracks or gaps in the smoke chamber, creosote or debris accumulation, and whether the flue is properly sized for the connected appliance. In Paterson’s party-wall chimneys, we can also identify whether exhaust is leaking from one flue into the shared masonry cavity or an adjacent flue. You receive photos of every finding and a plain-English verdict. No recommendation is made without evidence you can review yourself.
The National Fire Protection Association recommends annual inspection for all chimneys, flues, and venting systems. In Paterson’s older housing stock with coal-era masonry, party-wall configurations, and freeze-thaw exposure, we endorse that schedule without reservation. An annual Level 1 or Level 2 inspection catches liner deterioration, crown spalling, and draft problems before they become carbon monoxide hazards or require costlier rebuilds. Call (973) 604-2986 to schedule your inspection; estimates are free.
