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.
Fast, Reliable Chimney Liner & Rebuild Across Sunset Park
A chimney liner or rebuild in Sunset Park typically runs $1,800-$6,500 depending on whether you’re relining one flue or rebuilding a shared party-wall stack, and most jobs are completed in a single visit with a camera inspection included. Hearthstone Chimney Co. has served Sunset Park homeowners for decades, and our crews are familiar with the 1890s-1920s brick rowhouses that define this neighborhood. Call (516) 613-3035 - a live person answers 24 hours a day.
Dispatch and scheduling are coordinated from our New York City office, but our technicians live and work in Brooklyn. They know the difference between a chimney on 44th Street facing the harbor and one tucked inland between 4th and 8th Avenues. That local knowledge matters when you’re deciding whether a liner will suffice or the brick itself is too far gone.
Why Hearthstone Chimney Co. Is Sunset Park’s Preferred Chimney Liner & Rebuild Company
We’ve been answering calls with a live person for over 42 years, and that hasn’t changed. When a Sunset Park homeowner calls at 9 PM because their carbon monoxide detector went off, someone picks up. No voicemail. No callback queue tomorrow morning.
Our technicians are background-checked, uniformed, and trained to document every inspection with photos and a plain-English verdict. In Sunset Park’s dense rowhouse blocks, that documentation is especially important - shared chases and multiple appliances tied to original flues create situations where a verbal “it looks fine” isn’t enough. You get photos you can see, a written report, and a 90-Day Done Right Promise backed in writing with no arguing.
Most jobs are completed in a single visit. We carry professional-grade materials from DuraFlex, HeatShield, and Gelco on our trucks, so we’re not ordering parts and making you wait. No-hassle upfront pricing means the number on the estimate is the number on the invoice.
Our Chimney Liner & Rebuild Services in Sunset Park
Stainless Steel Liner Installation
Stainless steel liners are the standard for Sunset Park’s converted heating systems. Original coal-era chimneys were never designed for the lower exhaust temperatures of modern gas appliances, and an unlined flue lets acidic condensation eat the mortar from the inside. We install DuraFlex stainless liners with proper top plates and chimney caps, sized correctly for the appliance. In Sunset Park’s shared chases, we also verify that our liner doesn’t compromise draft in the adjacent unit - a step cheaper operations skip.

Flexible Liner Systems
Some of Sunset Park’s older chimneys have offset flues or tight cleanouts that make rigid stainless difficult to fish through. Flexible liners solve that without demolishing walls. We use professional-grade flexible products that maintain their shape and draft performance, not the builder-grade substitutes that sag after two heating seasons. A typical flexible liner installation in Sunset Park runs $1,800-$3,200.

Liner Replacement
When an existing liner has failed - cracked, separated at the joints, or corroded through - replacement is often more cost-effective than repeated patch jobs. In Sunset Park, we see this frequently in buildings that had a cheap liner installed during a quick flip or boiler swap in the 1990s. We pull the old material, inspect the surrounding brick with a camera, and install a new liner only if the chimney structure itself is sound. If the brick is spalling from salt exposure off Upper New York Bay, we’ll tell you straight: the liner won’t outlast the stack.

Partial Rebuild
Partial rebuilds address the top courses of brick, the crown, and sometimes the interior wythe where salt-laden harbor air has done the worst damage. This is common on Sunset Park’s ridge-facing rowhouses, where maritime exposure accelerates mortar joint failure beyond what you’d see in Flatbush or Midwood. We rebuild with matching brick where possible, pour a proper concrete crown with drip edges, and install a new cap. A partial rebuild in Sunset Park typically runs $2,800-$4,500.

Full Chimney Rebuild
When the interior wythe is compromised or multiple flues in a shared chase have failed, a full rebuild may be necessary. This is the most significant investment, ranging $4,500-$6,500 in Sunset Park, and we don’t recommend it lightly. The camera inspection comes first. You watch the footage. Then we discuss options.

Liner Repair
Minor liner damage - localized cracks, small joint separations - can sometimes be addressed with HeatShield cerfractory resurfacing rather than full replacement. This saves money when the underlying structure is sound. We only offer this after confirming the flue is otherwise intact; in Sunset Park’s older chimneys, surface repairs over hidden damage are a recipe for callbacks.

These are the brands specified by manufacturers who warranty their products. We don’t substitute builder-grade alternatives to shave cost.

We stock common sizes and fittings locally, so most Sunset Park jobs don’t wait on parts.
Common Chimney Liner & Rebuild Problems We See in Sunset Park Homes
- Shared party-wall chases with cross-contaminated flues. On densely packed blocks between 4th and 8th Avenues, a chimney often shares a multi-flue chase with the building next door. A technician who clears only one flue without checking the shared chase can leave a neighbor’s unit with a blocked or backdrafting flue. We scope the full chase and document what we find.
- Original terra cotta flues carrying multiple appliances. Many Sunset Park rowhouses were subdivided into multiple units, and a single flue now serves both a furnace and a water heater - a configuration that violates modern code and creates real carbon monoxide risk. A proper rebuild separates these or installs a correctly sized liner.
- Salt-laden maritime air accelerating mortar failure. Sitting on an elevated ridge directly facing Upper New York Bay, Sunset Park’s chimneys endure sustained winds carrying corrosive salt. Spalling brick and eroded joints appear years earlier than in inland Brooklyn. Annual inspection here is structural maintenance, not just soot removal.
- Freeze-thaw damage compounding salt corrosion. Winter moisture works into salt-compromised mortar, expands when it freezes, and opens new paths for more water. Spring inspections in Sunset Park often reveal crown and joint damage that wasn’t visible the previous fall.

FAQs - Chimney Liner & Rebuild in Sunset Park
Yes, we can reline your flue independently, but we always scope the shared chase first to confirm our work doesn’t create draft problems or cross-contamination for the adjacent unit. On a 1910s attached rowhouse off 6th Avenue in Sunset Park, our crew dropped a camera down a shared chase and found the flue serving the boiler had no liner at all, drafting into the adjacent unit’s stack. We pulled the original terra cotta, set a DuraFlex stainless liner with a new top plate and chimney cap, and rebuilt the spalling crown - but we only quoted it after the homeowner watched the footage on our screen. Call (516) 613-3035 if you suspect your flue is shared; we’ll verify before recommending anything.
Yes, because in Sunset Park the bigger risk isn’t creosote from burning - it’s structural deterioration from salt-laden harbor air and freeze-thaw cycling on aging brick. Many Sunset Park chimneys vent gas appliances, not wood fires, and those produce acidic condensation that eats unlined flues from the inside. An annual Level-2 inspection catches this before it becomes a carbon monoxide issue. Call (516) 613-3035 to book; estimates are free.
You see the evidence yourself. Our Level-2 inspection includes photos you can see and a plain-English verdict - documented like an engineer, explained like a craftsman. Nothing is recommended without camera footage you review with the technician. If the brick is sound and the flue is intact, we’ll say so. The 90-Day Done Right Promise means we have to stand behind what we recommend; overselling creates callbacks we don’t want. Call (516) 613-3035 for an inspection with no pressure to buy.
Salt-laden maritime air accelerates mortar joint erosion and brick spalling on exposed chimney stacks, which can compromise the liner’s support structure even when the liner itself is sound. The liner may test fine while the surrounding brick is failing - a situation we flag specifically because relining alone won’t solve it. Sunset Park’s ridge-top exposure makes this more severe than in inland Brooklyn neighborhoods. A camera inspection reveals the full picture. Call (516) 613-3035 to schedule.
Yes, it’s a significant problem. Multiple appliances sharing one flue is a known carbon monoxide and backdraft risk, especially in Sunset Park’s original 1890s-1920s chimneys that were never designed for modern gas exhaust. During a rebuild or relining, we separate these appliances to their own properly sized flues or install a liner rated for the combined load. This isn’t optional if we find it - we’ll document it, explain why it matters, and quote the correction. Call (516) 613-3035 for a free estimate.
