Fast, Reliable Chimney Liner & Rebuild Across North Bellmore
Chimney liner installation and rebuild services in North Bellmore typically run $2,800–$8,500 depending on scope, and most projects are completed in one to two days. If your 11793 home still runs its original postwar chimney on a converted gas system, that oversized flue is likely trapping moisture and deteriorating from the inside out — a pattern we correct weekly across this neighborhood.
We’re Robert Garcia and the team at Apex Chimney Cleaning Greater New York, and our Chimney Liner & Rebuild crew knows North Bellmore’s chimneys inside and out. From the Cape Cods lining Charles Street to the split-levels off Newbridge Road, we’ve spent 17 years working on the exact oil-to-gas conversion failures that define this 1945–1965 housing stock. When you call (866) 884-9512, you’re talking to Robert directly — the same person who’ll show up with the inspection camera and make the call on whether you need a stainless steel reline or a full rebuild. No dispatched crews, no subcontractors, no runaround.
Why Apex Chimney Cleaning Greater New York Is North Bellmore’s Preferred Chimney Liner & Rebuild Company
Our reputation in North Bellmore was built one chimney at a time — 1,096 verified reviews averaging 4.7 stars, with a significant share coming from repeat customers right here in the 11793 zip. These homeowners aren’t impressed by slogans; they’re impressed because Robert handles the work himself, from the initial Level II inspection to the final mortar joint.
Response time matters when you’ve got water staining your interior walls or a spalling crown letting drafts into your living room. We typically schedule North Bellmore inspections within 48 hours, and we carry the full inventory to complete most liner replacements and partial rebuilds in a single trip. That matters on Fairway Drive, where narrow driveways and tight property lines make multiple visits a genuine headache.
What separates us from competitors who rotate anonymous crews? Seventeen years of chimney-only focus means we’ve seen virtually every failure mode these postwar masonry chimneys can throw at us. We know which houses on the South Shore have the original clay tile liners sized for 1950s oil boilers, and we know exactly how those wide flues behave once a gas insert gets dropped in without proper relining. That local knowledge saves North Bellmore homeowners from the “band-aid repair that fails in two seasons” cycle.
Our Chimney Liner & Rebuild Services in North Bellmore
Stainless Steel Liner Installation
Stainless steel liners are our most common solution for North Bellmore’s converted gas systems. A typical 11793 installation runs $2,800–$4,500 for a straightforward single-flue reline, using DuraFlex or Olympia Chimney-grade 316Ti alloy that withstands the acidic condensation these oversized flues produce. We size the liner precisely to your appliance’s BTU output — critical on these postwar chimneys where the original 8×12 or 10×10 flue is now three times too large for a modern gas furnace. Robert measures every job himself; no guesswork on diameter or length.
Flexible Liner Systems
Some North Bellmore chimneys have offset flues, corbelled smoke chambers, or minor shifts from decades of freeze-thaw — especially in the ranch homes near the Meadowbrook Parkway corridor where clay soil movement isn’t unusual. Flexible liners from DuraFlex navigate these offsets without breaking the flue path, typically costing $3,200–$5,000 installed. We always run a video scan first to map the interior geometry; if the offset’s too severe, we’ll tell you upfront rather than force a solution that fails.
Liner Replacement
When an existing liner has corroded through, cracked at the joints, or separated from the appliance connector, replacement isn’t optional — it’s a carbon monoxide and fire hazard. In North Bellmore, we replace liners that were improperly installed during 1980s and 1990s gas conversions, often finding the original clay tiles still in place and deteriorating behind a thin aluminum sleeve. Replacement costs range $3,500–$6,000 depending on whether we need to remove the failed insert and rebuild the smoke chamber entrance. We document the entire process with before-and-after video; you’ll see exactly what was failing and why.
Partial Chimney Rebuild
Not every failing chimney needs to come down to the roofline. Partial rebuilds target the crown, the top few courses of brick, and the flue tile transition — the exact zones where North Bellmore’s salt-air corrosion and freeze-thaw cycling do their worst damage. A partial rebuild typically runs $4,500–$6,500 and preserves sound masonry below. Robert makes this call in person; we’ve saved more than one homeowner from an unnecessary full rebuild by catching the damage early enough to limit scope.
Full Chimney Rebuild
When the structural shell has compromised mortar joints throughout, spalled brick on multiple faces, or a leaning condition that indicates foundation settlement, full rebuild is the only safe path. In North Bellmore, this most often follows years of deferred maintenance on chimneys that were unlined after oil-to-gas conversion — the moisture damage works from inside and out simultaneously. Full rebuilds range $7,500–$12,000+ and include a new DuraFlex or Gelco stainless liner sized correctly for your current appliance. We handle permits, match existing brick where possible, and rebuild to current Nassau County code.

Trusted Brands We Service in North Bellmore
We install professional-grade materials — the same lines commercial contractors specify for Long Island’s coastal conditions. DuraFlex flexible and rigid stainless systems, HeatShield cerfractory flue resurfacing for minor tile degradation, and Gelco rigid liners for straight flue applications. We stock common diameters and fittings locally, which means most North Bellmore jobs don’t wait on parts. When we find spalled clay tiles on a 1960s chimney off Bellmore Avenue, we don’t have to order and return; we’ve got the liner and the refractory mix on the truck. Fast turnaround isn’t a slogan here — it’s inventory discipline built over 17 years.
Common Chimney Liner & Rebuild Problems We See in North Bellmore Homes
- Unlined oil-to-gas conversions with chronic condensation damage. The original wide flues designed for 1950s oil boilers now vent cooler gas exhaust, which condenses on clay tile surfaces all winter. That moisture freezes, expands, and spalls the tile from within — a failure pattern we find on nearly every block of North Bellmore’s postwar neighborhoods.
- Salt-laden coastal air accelerating metal and mortar deterioration. North Bellmore’s proximity to the South Shore bays means chimneys here corrode faster than inland Nassau County. We replace flashings and liner caps that failed prematurely, and we specify marine-grade stainless where standard 304 would struggle.
- Crown cracks from freeze-thaw cycling compounded by internal moisture. When an unlined flue sends damp exhaust against cold masonry, the crown takes the worst of it. We see horizontal cracking and spalling that lets water straight into the structure — often the first visible sign that prompts a call.
- Deferred liner replacement escalating to full rebuild scope. Homeowners who wait until exterior brick spalls or interior water stains appear are usually past the point of simple relining. We document this honestly; our 4.7-star average reflects customers who appreciate straight talk about whether a reline will suffice.

FAQs — Chimney Liner & Rebuild in North Bellmore
Yes — if your chimney was converted from oil to gas without a proper liner, the original oversized flue is almost certainly causing condensation damage that’s destroying your masonry from within. We find this exact scenario on the majority of 1945–1965 North Bellmore homes we inspect; the wide flue designed for high-temperature oil exhaust now runs too cool for gas, and the resulting moisture freezes in the clay tiles every winter. A properly sized stainless steel liner — typically 5″ or 6″ diameter for residential gas — corrects the draft, eliminates condensation, and protects the structure you’ve got left. Call (866) 884-9512 and we’ll video-scan it to confirm.
Look for horizontal cracking across the top surface, spalled or flaking concrete, or gaps between the crown edge and the brick courses below — and take any interior water stain on a ceiling or wall near the chimney seriously. In North Bellmore, crown damage accelerates because salt-laden coastal air penetrates micro-cracks, and internal moisture from unlined gas exhaust adds a second freeze-thaw cycle from inside. Robert checks crown condition on every inspection; early crown repair runs $800–$1,500, while deferred damage that reaches the flue liner typically escalates to partial or full rebuild scope.
Yes, and this is one of our most common North Bellmore scenarios — the 1950s boiler chimney with a 1990s gas insert that was never properly lined. We disconnect the appliance temporarily, remove any failed or undersized existing liner, and install a correctly sized stainless steel system that meets current NFPA 211 standards. The key is matching liner diameter to appliance BTU output and ensuring proper connector alignment; Robert handles this coordination personally rather than delegating to a subcontractor who might not understand the original masonry geometry.
Not always — but a leaning chimney is never something to monitor from the ground and hope for the best. We first determine whether the lean is structural (foundation settlement, compromised footing) or superficial (separated veneer, failed ties). In North Bellmore’s clay-heavy soils, minor settling is common on 60-year-old foundations; if the lean is under 2 degrees and the mortar joints are sound, we may recommend stabilization and a new liner rather than full teardown. Robert assesses this with a plumb line, crack monitoring, and structural evaluation during inspection. Call (866) 884-9512 — estimates are free, and leaning chimneys get priority scheduling.
A partial rebuild addresses the crown, top 2–4 feet of brick, and flue tile transition — the zones most exposed to weather and internal moisture — while preserving sound masonry below. A full rebuild removes the structure to the roofline or foundation and reconstructs with new materials, including a complete liner system. In North Bellmore, partial rebuilds typically suffice when damage is caught early and confined to the upper courses; full rebuilds become necessary when internal moisture has compromised mortar throughout, or when structural lean or foundation issues are present. Our 4.7-star review average reflects customers who appreciate that we don’t upsell full rebuilds when partial scope will solve the problem safely.
