Why Apex Chimney Cleaning Greater New York Is Elmont’s Preferred Chimney Liner & Rebuild Company
We’ve been climbing Elmont roofs for 17 years — long enough to know which houses on Alden Avenue were built in the same 1952 batch, which chimneys on Meacham Avenue still have their original clay tile liners, and how the freeze-thaw cycles coming off Jamaica Bay hit western Nassau County harder than points east. That specificity matters when you’re deciding between a liner repair and a full rebuild.
Our 1,096 verified customer reviews average 4.7 stars, and a significant share come from Elmont homeowners who found us after another company missed the real problem — usually an unlined oil flue still venting gas, or a cracked clay liner hiding behind what looked like “just a draft issue.” Robert Garcia doesn’t send crews; he’s the one on the ladder with the camera, reading the flue condition and making the call on the spot.
Response time to Elmont is typically same-day or next-day for inspections, because we’re already working in Franklin Square, North Valley Stream, and Cambria Heights most weeks. We don’t route you through a dispatch center. You call, you talk to someone who knows chimneys, and Robert schedules the visit himself.
Our Chimney Liner & Rebuild Services in Elmont
Stainless Steel Liner Installation
For most Elmont Cape Cods and colonials, a stainless steel liner is the right fix — especially when the original clay tiles are cracked from decades of freeze-thaw cycling. We install DuraFlex and Olympia Chimney stainless systems sized precisely for your appliance, whether it’s a gas furnace, boiler, or fireplace insert. A typical Elmont installation runs $2,800–$4,200 for a single-flue gas appliance, including removal of fractured clay tiles and proper top-sealing with a stainless cap. These liners carry a lifetime warranty when properly maintained.
Flexible Liner Systems
Elmont’s older chimneys often have offset flues or slight bends from settling — common in homes built on 40×100-foot lots with minimal footings. Flexible liners navigate these irregularities without breaking the flue wall, and we use them when a rigid stainless pipe won’t make the turn. Flexible installations in Elmont typically cost $3,200–$4,800, depending on flue length and whether we need to repair the smoke chamber above the fireplace. We’ve fitted these in chimneys from Dutch Broadway to the edges of Belmont Park’s residential blocks.
Liner Replacement
Not every liner failure demands stainless steel. When the existing liner is structurally sound but has localized damage — a cracked section near the top, a deteriorated connection at the appliance — we can replace segments using HeatShield cerfractory sealant or targeted stainless inserts. This is often the right call for Elmont homeowners whose chimneys were relined once already in the 1990s or 2000s and need a refresh rather than full replacement. Partial liner replacement in Elmont runs $1,800–$3,500.
Partial and Full Chimney Rebuild
Sometimes the liner isn’t the problem — it’s the chimney around it. Elmont’s 60-plus-year-old brickwork shows the damage: spalled crowns, crumbling mortar joints, leaning stacks. We see this especially on homes near Hempstead Turnpike where decades of road salt spray and coastal moisture have accelerated deterioration. A partial rebuild (crown replacement, upper course repointing, new cap) runs $3,500–$5,500. A full rebuild from the roofline up, including new flue construction and stainless liner, ranges from $6,500–$12,000 depending on height and accessibility. Robert assesses whether rebuild or relining is the smarter investment — he’s not interested in selling you a liner if the stack itself is failing.

Trusted Brands We Service in Elmont
We install professional-grade materials from DuraFlex, HeatShield, and Famco — the same lines commercial contractors use, not hardware-store substitutes. For Elmont customers, this means we can source replacement components quickly without waiting on national drop-shipping. A cracked DuraFlex connector or damaged Famco cap doesn’t turn into a two-week delay because we’ve built relationships with regional distributors who stock what our market needs. When we relined that Cape Cod on Alden Avenue, the DuraFlex stainless system was on the truck the next morning.
Common Chimney Liner & Rebuild Problems We See in Elmont Homes
- Cracked clay tile liners from freeze-thaw cycling. Nassau County winters cross 32°F dozens of times per season, driving water into hairline cracks and expanding it. In Elmont’s 60-plus-year-old chimneys, this fractures the original clay tiles and creates gaps where exhaust can leak into wall cavities or living spaces.
- Unlined oil flues left after gas conversions. A large share of Elmont’s Cape Cods were built with a single chimney stack housing both a fireplace flue and the original oil-burner flue side by side. When the oil system was swapped for gas — often without a proper relining permit — the oversized oil flue was left bare. Sweeps here routinely find that same unlined, draft-starved flue still venting a gas furnace decades later, invisible until a camera inspection reveals dangerous deterioration and backdrafting risk.
- Spalled brick crowns and crumbling mortar from coastal moisture. Western Nassau County receives enough damp air from Jamaica Bay and the Atlantic to keep masonry chronically wet. Deferred maintenance on crowns and pointing accelerates structural failure, turning a $3,500 crown-and-repoint job into a $10,000 full rebuild if ignored too long.
- Improperly sized flues after appliance upgrades. Modern high-efficiency gas appliances need narrower, properly sealed flues than the original oil or coal systems. An oversized flue venting a 90% efficient furnace creates condensation, acidic runoff, and liner deterioration — a pattern we see constantly in Elmont’s converted post-war housing stock.

FAQs — Chimney Liner & Rebuild in Elmont
Yes — almost certainly. The original clay tile liner sized for an oil burner is too large and too porous for a modern gas appliance, and the temperature difference causes acidic condensation that destroys the tiles from the inside out. In Elmont’s 1950s Cape Cods, we also commonly find the oil flue was never properly lined at all during conversion. Call (866) 884-9512 for a camera inspection — estimates are free, and we’ll show you exactly what your flue looks like inside.
Cracked clay tile liners from decades of freeze-thaw cycling, combined with unlined or improperly lined flues left after oil-to-gas conversions. The combination is nearly universal in Elmont’s 1945–1965 housing stock and creates a backdrafting risk that homeowners often mistake for “a drafty house.” We relined a classic Elmont Cape Cod on Alden Avenue where the original clay tile liner for the gas furnace was so cracked from freeze-thaw that the homeowner smelled exhaust in the basement. Our crew removed the fractured tiles and installed a 5-inch DuraFlex stainless steel liner, restoring proper draft and eliminating backdraft risk.
Yes — and in Elmont, this is exactly the configuration we see most often. The fireplace flue and the former oil-burner flue are separate channels within the same brick stack, and each needs its own properly sized liner. We can install stainless steel liners in both flues during the same project, typically completing the work in 1–2 days. The key is sizing each liner correctly for its appliance — one size does not fit both. Call (866) 884-9512 to schedule an inspection.
Repair if the spalling is superficial and the crown’s structural concrete or mortar cap is intact beneath; replace if the crown has cracked through, allowing water into the flue or between the chimney walls. In Elmont’s climate — with repeated freeze-thaw and coastal moisture — a compromised crown rarely stays minor for long. Robert Garcia will give you a straight assessment on the ladder: patch now and monitor, or rebuild the crown before winter. A crown replacement runs $3,500–$5,500 as part of a partial rebuild; delaying it can mean a full rebuild at double the cost.
A single-flue stainless steel liner installation for a typical Elmont Cape Cod — one story with accessible roof, standard gas furnace or boiler — runs $2,800–$4,200, with most homeowners landing near $3,400. Two-story sections, steep pitches, or the need to navigate an offset flue add labor and material. We use DuraFlex or Olympia Chimney systems with lifetime warranties. For an exact quote on your specific chimney, call (866) 884-9512 — inspections are free and we’ll have your written estimate before we leave.
