Call (888) 975-6389 for a free estimate.
We’ve been crossing the Sound to work in Kings Park for years, and we know the housing stock here: post-war ranches along Old Northport Road, split-levels near the Nissequogue River, and Cape Cods tucked behind Sunken Meadow State Parkway. These homes weren’t built for today’s heating systems. Gary Murphy, our owner and lead technician, handles every liner and rebuild job personally — 14 years in the chimney trade, one specialty, no subcontractors. When you’re staring at a cracked flue or a chimney crown that’s shedding mortar into your yard, you want the person whose name is on the truck, not a rotating crew.

No chasing down forms, no surprises at inspection.
Our Chimney Liner & Rebuild Services in Kings Park
Stainless Steel Liner Installation
Kings Park’s oil-to-gas conversion wave has made stainless steel relining our most requested service in 11754. The original clay tile liners in these 1950s–1970s chimneys were sized for 400°F+ oil-burner exhaust; switch to a 90% efficient gas unit, and the flue temperature drops below 200°F. The result is a river of acidic condensate running down walls that were never designed for it. We install DuraFlex and Olympia Chimney stainless steel liners — 316Ti alloy for gas, 304 for solid fuel — properly insulated and sized to the appliance’s BTU output. This isn’t a slip-in fix; we calculate draft requirements, verify clearances to combustibles in these older chase enclosures, and install a proper top plate and rain cap that seals against Kings Park’s driving north-shore weather.
Flexible Liner Systems
Not every Kings Park chimney is straight. The ranches and Cape Cods along the bluffs near Long Island Sound often have offset flues, dogleg offsets around second-floor additions, or chimney shifts from decades of freeze-thaw movement. Flexible liners — DuraFlex’s corrugated stainless or Gelco’s smooth-wall systems — navigate these obstacles without breaking the flue’s integrity. We pull these with controlled tension, never the brute force that kinks or ovalizes the liner. For a home near Commack Road with a 3-foot offset into the attic, a flexible system can mean the difference between a same-day relining and a $15,000 teardown.
Liner Replacement
Sometimes the liner isn’t just cracked — it’s gone. We’ve pulled collapsed clay tile out of Kings Park chimneys where the bottom six feet had turned to rubble, blocking draft and forcing carbon monoxide into the basement. Liner replacement starts with a full video scan so we show you exactly what we’re seeing: spalled tile, missing mortar joints, or the black acidic staining that signals condensate damage. We remove the failed material, clean the flue walls, and install a new system with proper connectors to your appliance. In Kings Park’s older single-wythe brick chimneys, we often find the original liner was never listed to any standard — just field-laid clay tile with no insulation. We bring it to current NFPA 211 and local code.
Partial Chimney Rebuild
The salt-laden air off Smithtown Bay doesn’t negotiate. We’ve rebuilt crowns, rebuilt the top four to six courses of brick, and replaced deteriorated wythes on chimneys from Elwood to the edges of Sunken Meadow. Partial rebuild makes sense when the lower chimney structure is sound but the upper section — the part most exposed to wind, rain, and salt — has lost mortar integrity. We match existing brick where possible, repoint with Type N mortar formulated for coastal exposure, and integrate a new liner system that doesn’t repeat the original failure. For a Kings Park homeowner, this preserves the chimney’s footprint while solving the root problem.
Full Chimney Rebuild
When a 60-year-old single-wythe stack has shifted off its foundation, when multiple wythes have separated, or when the cost of piecing repairs exceeds 60% of replacement, we recommend full rebuild. We’ve done this on homes near Old Northport Road where the chimney had essentially become a decorative brick column with no structural connection to the flue. Full rebuild means new footing if needed, reinforced block or brick construction to current code, proper clearance to combustibles that the original builders ignored, and a liner system sized for your actual appliance — not the oil burner that was scrapped in 2019.

Trusted Brands We Service in Kings Park
We don’t source from hardware store shelves. Our Kings Park jobs use DuraFlex stainless liners and components, HeatShield cerfractory resurfacing systems for flue walls that need structural restoration without full replacement, and Gelco caps and flashing kits. These are the brands specified in chimney professional supply houses, not marketed to homeowners in big-box aisles. We stock common diameters and fittings — 6-inch and 7-inch round, oval adapters for fireplace inserts, top plates for both square and rectangular flues — which means most Kings Park liner jobs don’t wait on shipping. When we find a problem during inspection, we can often return and complete within 48 hours.
Common Chimney Liner & Rebuild Problems We See in Kings Park Homes
- Acidic condensate from oil-to-gas conversions. The single most dangerous pattern we find in Kings Park: a high-efficiency gas appliance venting into a flue built for hot oil exhaust. The cooler flue gas condenses into sulfuric acid that eats clay tile, corrodes unprotected metal, and stains interior masonry black. Homeowners smell “something odd” or notice water in the cleanout — by then, the liner is often compromised.
- Salt-air mortar erosion on exposed brick. Chimneys within a half-mile of Smithtown Bay show accelerated joint deterioration. The salt doesn’t just discolor; it hygroscopically attracts moisture, expands in freeze-thaw, and pops mortar joints loose. Loose mortar means liner movement, which means gaps and leaks.
- Crown cracking from north-shore freeze-thaw cycling. Kings Park’s climate is moderated enough by Long Island Sound that freeze-thaw cycles repeat dozens of times per winter — not one deep freeze, but constant assault. Crown mortar cracks, water enters behind the liner, and the next freeze pops the liner off its support or cracks tile from the outside.
- Undersized flues after insert or stove installations. A wood-burning insert rated for a 6-inch liner gets shoved into a fireplace with an 8-by-12 clay flue. The oversize flue cools the smoke, creosote condenses on the liner walls, and the effective draft drops below safe levels. We see this in Kings Park’s 1960s ranches where homeowners added inserts for supplemental heat without relining.
Pricing for Chimney Liner & Rebuild in Kings Park, NY
| Service | Typical Range in Kings Park |
|---|---|
| Stainless steel liner installation (gas appliance, standard height) | $2,800 – $4,500 |
| Flexible liner with offset navigation | $3,200 – $5,200 |

These ranges reflect Kings Park’s typical two-story ranch and Cape Cod heights — roughly 18 to 24 feet from foundation to crown. Taller chimneys, multiple flues, or chase enclosure modifications add cost. What drives the final number: liner diameter and alloy, whether the flue is straight or offset, condition of existing masonry, and whether the appliance connection requires a custom adapter. We don’t guess from photos. Every estimate starts with a camera inspection — free, no obligation, and you’ll see what we see on the monitor. Call (888) 975-6389 to schedule.

FAQs — Chimney Liner & Rebuild in Kings Park
The original clay tile liners in Kings Park’s 1950s–1970s homes were sized for 400°F+ oil-burner exhaust, but high-efficiency gas appliances produce flue gas below 200°F that condenses into sulfuric acid. Stainless steel — specifically 316Ti alloy for gas applications — resists that acidic condensate, maintains structural integrity through thermal cycling, and can be properly insulated to maintain adequate draft temperature. Call (888) 975-6389 for a free inspection if you’ve converted without relining.
Salt-laden air accelerates mortar joint erosion on exposed brick chimneys, which allows liner movement, gaps, and eventual flue gas leakage into the home. The salt also hygroscopically attracts moisture, amplifying freeze-thaw damage to crowns and top courses that protect the liner assembly. We address this with galvanized or stainless caps, proper crown overhangs, and repointing with coastal-formulated mortars when we integrate a new liner. Call (888) 975-6389 for an inspection if your chimney is within a half-mile of the water.
Yes — in most Kings Park homes, we install a new stainless or flexible liner through the existing flue without masonry demolition. The exceptions are chimneys with structural failure, separated wythes, or insufficient clearance to combustibles that can’t be resolved with an insulated liner system. Our camera inspection determines which path applies to your chimney. Call (888) 975-6389 to schedule that inspection.
We install DuraFlex and Olympia Chimney stainless steel liners, HeatShield cerfractory resurfacing systems for flue walls that need structural repair without full replacement, and Gelco caps and flashing components. These are professional-grade materials sourced through chimney-industry supply channels, not retail hardware stores. Call (888) 975-6389 to discuss which system fits your appliance and flue configuration.
Yes — partial rebuild is often the right solution for Kings Park’s 50–70-year-old chimneys where the lower structure remains sound but the upper section has suffered salt-air erosion or freeze-thaw damage. We rebuild from the roofline up, matching existing brick where possible, integrating a new liner system, and sealing with a proper crown and cap. Gary Murphy evaluates each chimney personally to determine whether partial or full rebuild is the better investment. Call (888) 975-6389 for that evaluation.
