Why Hearthstone Chimney Co. of New York City Is Sunset Park’s Preferred Chimney Liner & Rebuild Company
We’ve worked on chimney stacks from 44th Street to 65th Street, from the waterfront blocks facing Upper New York Bay to the interior streets around Sunset Park itself. Our technicians know the difference between a standard liner pull and the delicate work required when three flues share a single stack with party-wall construction. Sunset Park homeowners recognize our trucks, and they recognize our approach: photos you can see, a plain-English verdict, and a written estimate before any work begins.
Our reputation here was built slowly, the way good mortar cures. We arrive when we say we will. Our background-checked, uniformed technicians carry the professional-grade materials needed for most jobs - DuraFlex stainless liners, HeatShield crown sealant, Gelco caps - so we’re not making multiple trips through Sunset Park’s narrow streets. The 90-Day Done Right Promise governs every job: if it’s not right, we come back, in writing, no arguing.
Calls from 11220 reach our live dispatchers around the clock. We don’t use voicemail queues or callback apps. A real person takes your information, checks technician availability, and gives you a window we intend to keep. For emergency situations - carbon monoxide backdrafting from a collapsed flue, visible masonry collapse after a storm - we prioritize same-day response in Sunset Park because the density of these row houses means one compromised stack can affect multiple families.
Our Chimney Liner & Rebuild Services in Sunset Park
Stainless Steel Liner Installation
Most Sunset Park row houses were built with clay tile flues sized for coal heat, then adapted for oil burners without relining. Those original tiles are now cracked, missing sections, or deteriorated from decades of acidic condensation. We install DuraFlex stainless steel liner systems sized precisely for your current appliance - oil boiler, gas water heater, or fireplace - restoring proper draft and containing flue gases safely. In Sunset Park’s shared stacks, proper liner sizing is critical: an oversized flue for a modern appliance causes sluggish draft and condensation damage, while an undersized one creates a fire hazard. We measure twice and document everything with our Level-2 camera inspection.
Flexible Liner Systems
The offset flues common in Sunset Park’s converted row houses - shifts built in to navigate around floor joists and party walls - often rule out rigid liner sections. Our flexible DuraFlex liners navigate these offsets without compromising the smooth interior surface that proper draft requires. We’ve pulled flexible liners through flues with multiple bends in buildings along 7th Avenue and the side streets between, where rigid pipe simply wouldn’t make the turn. The installation is demanding work in tight spaces, but our technicians complete most jobs in a single visit with the materials stocked on our trucks.
Liner Replacement & Repair
Not every deteriorated liner needs full replacement. Where clay tiles are partially cracked but the flue structure is sound, we can install a HeatShield cerfractory resurfacing system - a specialized resurfacing material that fills gaps and restores a smooth, insulated flue surface at lower cost than full relining. For Sunset Park homeowners with decorative fireplaces that see occasional use, this can be the right middle path. We document the existing condition with camera photos, explain what we found in plain English, and give you a real choice. No pressure. The number on the estimate is the number on the invoice.
Partial & Full Chimney Rebuild
Sunset Park’s ridge-top exposure to harbor winds accelerates mortar spalling and crown deterioration beyond what inland Brooklyn neighborhoods experience. When the top courses of your stack are crumbling, or when multiple flues have suffered structural collapse, a rebuild becomes necessary. Our partial rebuilds address the crown and upper courses - the most common failure point here - using proper weather-resistant mortar and rebuilt crowns sealed with HeatShield. Full rebuilds, required when the stack has suffered extensive water infiltration or structural compromise, restore the chimney from the roofline up with matching brick and proper flue separation. We recently relined a shared stack on 5th Avenue where three flues - serving an oil boiler, gas water heater, and decorative fireplace - had cracked original clay tiles. The top courses were spalled from salt air, so we installed a full DuraFlex stainless steel liner system and rebuilt the crown with HeatShield sealant to prevent cross-unit CO backdrafting.

Trusted Brands We Service in Sunset Park
We stock professional-grade materials from the brands that chimney professionals actually trust: DuraFlex for flexible and rigid stainless liners, HeatShield for flue resurfacing and crown repair, Gelco for caps and termination fittings.

Every installation is documented with before-and-after photos, and every material choice is explained in your written report.
Common Chimney Liner & Rebuild Problems We See in Sunset Park Homes
- Cracked or missing clay tile liners in pre-1925 row houses - The original coal-era clay flue tiles in Sunset Park’s attached brick houses have endured 100+ years of thermal cycling and acidic flue gases. We regularly find tiles cracked diagonally, missing entire sections, or reduced to rubble at the base of the flue. This allows flue gases to leak into wall cavities and creates the conditions for cross-unit carbon monoxide backdrafting in shared stacks.
- Salt-driven mortar spalling on exposed chimney crowns - Sunset Park’s direct sightline to Upper New York Bay funnels harbor winds saturated with salt spray onto ridge-top chimney stacks. This accelerates spalling and mortar joint failure far beyond inland Brooklyn rates. Freeze-thaw cycles acting on salt-saturated brick destroy the top courses of stacks, allowing water infiltration that compounds the damage through successive winters.
- Oversized flues from original coal-heat design - The flues in these 1885-to-1925 row houses were sized for coal-fired boilers that produced massive volumes of hot flue gas. Modern oil and gas appliances run cooler and produce less volume, so the original flue is now grossly oversized. This causes poor draft, condensation of acidic moisture on flue walls, and accelerated deterioration of any remaining liner material. Proper relining with correctly sized stainless pipe solves this permanently.
- Cross-unit backdrafting in shared three-flue stacks - In the tightly packed row houses along 5th and 6th Avenues, a single shared chimney stack frequently serves three separate units with three separate appliances. When one flue is blocked or its liner has collapsed, combustion gases can be drawn into adjacent flues and from there into neighboring apartments. This is a genuine safety issue that demands immediate attention and proper liner separation.

FAQs - Chimney Liner & Rebuild in Sunset Park
Sunset Park’s chimney liners fail faster because the neighborhood sits on a high ridge with direct exposure to salt-laden winds from Upper New York Bay, which accelerates mortar spalling and crown deterioration, while the area’s century-old shared stacks with original coal-era clay tiles create chronic condensation and draft problems when adapted to modern appliances. The combination of salt-driven masonry damage and improperly sized flues means Sunset Park stacks require more frequent inspection and earlier intervention than inland Brooklyn neighborhoods. Call (855) 950-3861 to schedule a Level-2 inspection - estimates are free.
Yes, a liner can be installed for a single flue within a shared stack, and this is precisely the solution we regularly implement in Sunset Park’s multi-unit row houses where one appliance needs relining while adjacent flues remain functional. We use flexible stainless liners that navigate the existing flue without disturbing neighboring units, and we seal the top with proper termination fittings to maintain separation between flues. The critical step is verifying that adjacent flues are intact and properly drafted so your new liner doesn’t draw gases from a compromised neighbor flue. Call (855) 950-3861 - we’ll inspect the full stack and give you a written plan for your specific flue.
Tight alley access and parking restrictions in Sunset Park mean our crews arrive with materials pre-staged on the truck, use compact equipment for material handling, and coordinate timing to minimize disruption on narrow streets like those between 5th and 6th Avenues. We don’t need to block your neighbor’s driveway or occupy scarce curb space with a separate delivery; our trucks carry the brick, mortar, liner sections, and scaffolding components needed for most rebuilds. For full rebuilds requiring more material, we schedule off-peak delivery and stage in designated loading zones. We’ve done this work on these blocks for over 42 years. Call (855) 950-3861 and we’ll walk through the access plan for your specific property.
Most chimney liner replacements in Sunset Park do not require a permit if the work is contained within the existing flue and does not alter the chimney structure, but partial or full rebuilds that modify the stack above the roofline typically require a permit from the NYC Department of Buildings. We handle permit applications as part of our rebuild projects and include this in our written estimate so there are no surprises. For liner-only work, we’ll tell you explicitly if your specific situation triggers any filing requirement. Call (855) 950-3861 for clarity on your job - estimates are free.
Yes, we regularly reline decorative fireplace flues in Sunset Park’s original coal-fired row houses, and this is often the safest approach because the original clay flue was sized for coal combustion and is now oversized for occasional wood or gas fireplace use, creating draft and condensation problems. We install properly sized stainless liners - sometimes flexible, sometimes rigid depending on flue geometry - and can adapt the termination for your intended fuel. If the fireplace is purely decorative and will never be used, we may recommend a simpler vented cap solution after inspection. The right answer depends on what you actually intend. Call (855) 950-3861 for a free inspection and written recommendation.
