Fast, Reliable Chimney Liner & Rebuild Across Gravesend
Chimney liner installation and rebuild work in Gravesend typically runs $2,800–$7,500 depending on whether you need a stainless steel liner dropped through an existing flue or a partial rebuild of a salt-damaged stack, and Robert Garcia usually completes standard relines in one day. We’re on the road throughout southwest Brooklyn every morning, which means we can often inspect your chimney on Avenue U, McDonald Avenue, or the blocks off Coney Island Avenue the same day you call. Gravesend’s tight row-house lots and shared party-wall chimneys demand a technician who understands clearance limits, directional mortar damage, and how to thread liners through century-old flues without disturbing your neighbor’s system. If you’re seeing brick flakes on your roof or getting DOB notices about an unlined flue, call (866) 884-9512 for a free estimate.
Why Apex Chimney Cleaning Greater New York Is Gravesend’s Preferred Chimney Liner & Rebuild Company
We’ve been climbing Gravesend roofs for 17 years, and the salt-laden Atlantic wind from Coney Island has taught us patterns that inland Brooklyn techs rarely encounter. Our Chimney Liner & Rebuild team knows which blocks near the Belt Parkway see one-sided spalling and which 1920s two-family stacks have the narrow coal flues that make flexible liner installation tricky.
Homeowners in Gravesend have left us 1,096 verified reviews averaging 4.7 stars, and many mention Robert Garcia by name because he’s the one who shows up, diagnoses the problem, and does the work. We’re not dispatching anonymous crews from a central office. When you book in Gravesend, Robert handles it himself.
Our response time to the 11223 zip code is typically same-day or next-morning, because we’re already working in Bath Beach, Bensonhurst, or Brighton Beach most days. That matters when you’ve got a boiler down in January or a DOB violation notice with a deadline.
Our Chimney Liner & Rebuild Services in Gravesend
Stainless Steel Liner Installation
Gravesend’s attached brick two-family homes were built with coal flues that are too small and too rough for modern gas appliance venting. We install 304 or 316-grade stainless steel liners—often DuraFlex or Olympia Chimney systems—that create a sealed, correctly sized passage from your boiler or water heater to the top of the stack. On the row houses near Avenue U and Coney Island Avenue, we regularly drop 6-inch round liners through 8×8-inch square flues originally designed for coal-fired furnaces, then seal the gap with proper insulation to meet NFPA 211 standards. The salt corrosion from Coney Island’s onshore winds makes stainless steel essential here—aluminum or clay tile simply don’t survive.
Flexible Liner Installation
Some Gravesend chimneys have offset flues, corbelled shoulders, or tight bends where rigid stainless pipe won’t pass. For these, we use DuraFlex or Gelco flexible liner systems that navigate obstructions while maintaining a continuous, sealed vent path. We see this often in the 1930s attached homes between McDonald Avenue and the Belt Parkway, where builders used stepped corbels to shift the flue around floor joists. Flexible liner installation in Gravesend typically costs $2,800–$4,200, compared to $3,500–$5,500 for rigid systems, and Robert can usually tell you which you’ll need after a 15-minute camera inspection.
Liner Replacement & Repair
Not every unlined or damaged flue needs full replacement. In Gravesend, we sometimes find that a previous homeowner installed a liner that was never properly connected to the appliance collar, or that salt corrosion has eaten through a section near the crown while the lower flue remains sound. HeatShield cerfractory flue sealant lets us resurface cracked clay tile or patch localized liner damage without a full tear-out. For a two-family shared stack on West Street or Van Sicklen Street, this can mean repairing one flue while leaving your neighbor’s system untouched—a significant cost savings when a full replacement isn’t necessary.
Partial Chimney Rebuild
Here’s where Gravesend’s coastal geography changes everything. The salt-laden Atlantic wind from Coney Island damages only the south and southwest-facing sides of chimneys, creating one-sided spalling that often requires directional repointing instead of a full rebuild. We’ve rebuilt dozens of partial stacks in Gravesend where the north face is solid 1920s brick and the south face is crumbling from freeze-thaw salt damage. Robert assesses each stack individually—if we can save three sides and rebuild one, you’ll spend $3,500–$5,500 instead of $8,000–$12,000 for a full teardown. We worked on a 1930s attached row house on Avenue U near the Belt Parkway that had severe crown cracking and brick face-scaling on the south face only. Our crew installed a 6-inch DuraFlex stainless steel liner through the original coal flue, sealed the crown, and tuckpointed only the damaged side—extending the stack life without a full rebuild.

Common Chimney Liner & Rebuild Problems We See in Gravesend Homes
- Undersized flues from 1950s gas conversions crack or separate because they were never lined for modern appliance BTU output. The original coal flue in your Gravesend two-family was designed for a slow, cool burn, not an 80,000 BTU gas boiler. Relining with flexible metal isn’t optional—it’s code compliance.
- Shared party-wall stacks with two flues often have one flue unlined, and NYC DOB inspections flag this code deficiency. We’ve relined the “owner’s side” flue in dozens of Gravesend two-families while coordinating access with the neighbor to avoid disturbing their venting.
- Partial rebuild fails if the new liner isn’t continuous through the shared stack. We’ve been called to fix other contractors’ work where a liner was dropped only to the first floor, creating a dangerous gap where combustion gases can leak into the party wall cavity.
- Salt-spalled bricks on south-facing sides flake off during winter freeze-thaw cycles, leading to chimney leans if one-sided mortar is not addressed quickly with directional tuckpointing. The blocks closest to Coney Island Avenue and the Belt Parkway show this pattern most severely.
Pricing for Chimney Liner & Rebuild in Gravesend, NY

What moves you up or down within these ranges? Flue height is the big one—Gravesend’s three-story two-families need more liner material than a single-story bungalow. Accessibility matters too: if we’re working off a ladder on a narrow lot versus setting a scaffold on a wider driveway. Shared stacks cost more because we coordinate two households and ensure both flues are safe before we leave. The salt damage pattern common near Coney Island can mean directional tuckpointing saves money, or it can reveal hidden structural issues that require more extensive work. We give exact quotes after inspection, and estimates are always free. Call (866) 884-9512 to schedule.

FAQs — Chimney Liner & Rebuild in Gravesend
Yes, we can reline only your flue in a shared Gravesend stack, provided the work doesn’t compromise the structural integrity of the common chimney or your neighbor’s venting path. Robert will inspect both flues with a camera to map the internal layout, then install a continuous liner from your appliance to the top of the stack, sealing around the penetration to prevent cross-flue leakage. We coordinate access with your neighbor and document the work for both households. Call (866) 884-9512 to arrange a joint inspection—estimates are free.
Yes, if your Gravesend chimney was built for oil or coal and you converted to gas, relining is typically required by NYC code and necessary for safe operation. Gas appliances produce more moisture and cooler flue gases than oil, which condense on unlined masonry and accelerate the freeze-thaw damage already worsened by Gravesend’s salt-laden coastal air. We’ve relined dozens of post-conversion chimneys in 11223 where the original clay tile was cracked or missing entirely. Call (866) 884-9512 for a camera inspection and exact quote.
One-sided cracking on the south or southwest face is extremely common in Gravesend due to directional salt-wind exposure from Coney Island, and it often means you need targeted tuckpointing rather than a full rebuild. The north face of the same stack is frequently intact because it’s shielded from the prevailing Atlantic winds. Robert looks for this pattern on every Gravesend inspection—saving the solid brick and rebuilding only the damaged side cuts costs significantly. Call (866) 884-9512 to confirm whether your damage is directional or structural.
Yes, chimney liner installation in Gravesend requires a NYC DOB permit, and if you’re in a two-family home with a shared stack, the work may trigger a Type 2 inspection. Robert handles permit filing as part of our service—we’ve done enough Gravesend jobs to know the 11223 district office’s requirements and typical turnaround. The permit cost is usually included in our quoted price. Call (866) 884-9512 and we’ll confirm whether your specific job needs full permitting or qualifies for a simpler filing.
A partial rebuild with liner installation on a Gravesend row house near the Belt Parkway typically takes two to three days: one day for demolition and liner installation, one day for bricklaying and mortar curing, and sometimes a half-day for final sealing and cleanup. Robert works with a small, consistent crew, so the same people who start your job finish it—we don’t rotate unknown subcontractors through your home. Weather matters in Gravesend’s exposed coastal zone; we watch the forecast and won’t start mortar work if overnight temperatures threaten freeze. Call (866) 884-9512 to check current scheduling.
