Fast, Reliable Chimney Liner & Rebuild Across Hicksville
A chimney liner or rebuild in Hicksville typically costs between $1,800 and $6,500 depending on whether we’re resurfacing an existing flue or rebuilding from the crown down, and most jobs are completed in one to two days. If you’re smelling smoke in your living room, seeing white efflorescence on your exterior brick, or your HVAC technician flagged a cracked flue during routine service, the underlying problem is likely a deteriorated liner in a chimney built during Hicksville’s post-war construction boom. We’re based in New York City and regularly run out to Nassau County — call (866) 884-9512 for a free estimate, and we’ll have Robert Garcia, our owner and lead technician, on your property to assess it personally.
We’ve been working on Hicksville chimneys long enough to know the pattern: a ranch or Cape Cod near North Broadway or down by Clearview Village, built in 1952 or 1963, original clay tile liner, oil furnace swapped for gas sometime in the 1990s or 2000s. The flue’s too big for the new appliance, exhaust cools too fast, condensation forms, and that carbonic acid eats the tile from the inside out. Standard sweeping won’t fix it. We will.
Why Apex Chimney Cleaning Greater New York Is Hicksville’s Preferred Chimney Liner & Rebuild Company
Our Chimney Liner & Rebuild team has handled more than 1,096 verified jobs across Greater New York, maintaining a 4.7-star average, and a significant portion of those calls come from Nassau County’s post-war suburbs. Hicksville homeowners aren’t looking for a dispatcher sending an anonymous crew — they want the person who owns the company and stakes his reputation on every joint, every liner section, every mortar mix. Robert Garcia handles it himself. He’ll walk your roof, drop a camera down your flue, and explain exactly what you’re seeing on the monitor.
We know the local response landscape. From our base, we’re typically at Hicksville properties within 45 minutes to an hour, whether you’re off Hempstead Turnpike near the Eisenhower Park corridor or in the residential streets around Woodbury Oaks at Woodbury. That matters when you’ve got a backdrafting water heater or a chimney inspection contingency on a home sale.
Our familiarity with Hicksville’s housing stock runs deep. We’ve relined chimneys in Birchwood at Jericho, rebuilt crowns in Clearview Village, and diagnosed condensation-damaged flues in the original Levitt-era ranches that line streets between Newbridge Road and North Broadway. We don’t need a map to find your neighborhood, and we don’t need a manual to recognize what 60-year-old clay tile looks like when gas exhaust has been condensing inside it for two decades.
Our Chimney Liner & Rebuild Services in Hicksville
Stainless Steel Liner Installation
For most Hicksville homes with oil-to-gas conversion damage, a continuous stainless steel liner is the definitive fix. We install DuraFlex and Olympia Chimney-grade systems that drop down the existing flue and create a properly sized, corrosion-resistant passage for exhaust gases. In a typical Hicksville ranch with a 1950s brick chimney, the original clay flue might measure 8×12 inches — sized for an oil furnace running at 500°F plus. Your modern gas boiler needs a 5- or 6-inch round flue to maintain adequate draft and prevent condensation. Without it, that acidic moisture keeps destroying masonry. Our stainless installations run $2,200–$3,800 in Hicksville, including removal of damaged tile and proper top-sealing with an insulated crown connection.
Flexible Liner Systems
Not every Hicksville chimney is straight. Cape Cods with offset flues, or ranches where a previous homeowner added a second-story dormer, can present bends that rigid pipe won’t navigate. We use DuraFlex flexible stainless liners that conform to gradual offsets while maintaining the full structural integrity of their rigid counterparts. These are particularly valuable in Hicksville’s tighter lots where exterior rebuild space is limited and interior flue access is the only practical route. Flexible liner jobs in Hicksville typically fall between $2,800 and $4,200 depending on length, diameter, and whether we need to remove an existing damaged liner first.
Liner Replacement & Repair
Sometimes the liner isn’t fully destroyed — it’s cracked at the top, shifted at a joint, or damaged by a chimney fire that the homeowner didn’t realize happened. We evaluate with a video scan before recommending full replacement. In Hicksville’s climate, where salt air from Long Island Sound accelerates exterior mortar decay, we’ve found that water intrusion through a failed crown often masks as liner damage. Robert Garcia will distinguish between the two. Spot repairs with HeatShield cerfractory resurfacing run $1,800–$2,800 when the underlying clay structure is sound. If the tile is spalled more than 30% of its surface, replacement is the only honest recommendation.
Partial Chimney Rebuild
When the liner damage has progressed to the point of structural compromise — or when exterior spalling from freeze-thaw cycles has opened the chimney to persistent water entry — a partial rebuild becomes necessary. This typically means rebuilding from the roofline up: new crown, new brick or block to grade, new flashing integration, and a properly sized liner installed through the reconstructed flue. In Hicksville’s 60–75-year-old housing stock, we perform this work regularly. Partial rebuilds with liner integration run $4,500–$6,500 depending on height, accessibility, and whether we need to match existing brick. We’ve rebuilt chimneys visible from Newbridge Road and tucked into backyards off side streets in Woodbury Oaks at Woodicho — each with the same standard: Robert Garcia oversees every course of brick and every liner connection.
Full Chimney Rebuild
The most severe cases — typically where decades of deferred maintenance, multiple liner failures, and structural settling have compromised the chimney below the roofline — require complete teardown and reconstruction. This is less common in Hicksville than partial rebuilds, but we’ve done them, especially in properties where the original chimney was built without proper footings or where soil conditions have shifted the structure. Full rebuilds start around $8,500 and include engineered footing verification, code-compliant construction, and a stainless or flexible liner system sized precisely to your appliance. We pull permits, coordinate inspections, and warranty our work.

Trusted Brands We Service in Hicksville
We don’t source from big-box closeout bins. For Hicksville installations, we stock and install professional-grade materials from DuraFlex, HeatShield, and Copperfield — the same lines commercial masonry contractors specify for multi-unit buildings. DuraFlex gives us the flexible stainless inventory for Hicksville’s offset flues; HeatShield provides the cerfractory resurfacing compound for salvageable clay structures; Copperfield supplies our caps, dampers, and crown-forming materials. We keep common diameters and fittings on hand, which means most Hicksville liner jobs don’t wait on shipping. When you’re dealing with a heating system shutdown or a real estate deadline, that turnaround matters.
Common Chimney Liner & Rebuild Problems We See in Hicksville Homes
- Inside-out clay tile deterioration from gas conversion. Hicksville’s dominant housing type — the 1947–1965 oil-heated ranch or Cape Cod — presents a near-universal failure mode: clay flue tiles sized for 500°F oil exhaust now vent 250°F gas appliances, causing condensation that forms carbonic acid and spalls tile from the interior surface outward. Standard sweeping removes creosote but cannot restore structural integrity to acid-eaten clay.
- Salt-laden air eroding exterior mortar joints. Nassau County’s position between Long Island Sound and the Atlantic exposes Hicksville chimneys to persistent salt air, especially for properties east of Newbridge Road with less tree buffering. Mortar joints degrade faster here than in inland suburbs, accelerating the path to water intrusion and liner damage that requires full rebuild rather than simple repointing.
- Freeze-thaw crown and flashing failures. Long Island winters deliver dozens of freeze-thaw cycles annually. Water enters hairline cracks in chimney crowns or gaps in step flashing, expands when frozen, and progressively opens the chimney to bulk water entry. By March, we’re fielding calls from Hicksville homeowners who noticed new interior water stains directly below their chimney chase.
- Undersized or absent liners in converted systems. Many Hicksville oil-to-gas conversions were performed by HVAC contractors who focused on the appliance, not the venting. We regularly find gas water heaters or high-efficiency boilers connected to original clay flues with no liner at all — a code violation and a carbon monoxide risk that demands immediate correction.
Pricing for Chimney Liner & Rebuild in Hicksville, NY

These ranges reflect Hicksville’s market specifically — labor costs in Nassau County run higher than Suffolk or farther east, but lower than Manhattan or immediate Brooklyn. Material costs are consistent across our service area. What drives variation is condition: a chimney with intact exterior masonry and a straight flue sits at the lower end; one with spalled brick, multiple offsets, and water-damaged interior structure requires more labor and moves toward the upper end. We provide written, itemized estimates before any work begins. Call (866) 884-9512 to schedule — estimates are free, and Robert Garcia will assess your chimney personally.

FAQs — Chimney Liner & Rebuild in Hicksville
Your clay flue tiles are deteriorating from inside-out carbonic acid corrosion, not surface creosote buildup — a condition caused by gas appliance exhaust condensing in an oil-era flue that’s too large to maintain adequate temperature. In Hicksville’s converted ranches and Cape Cods, this is the most common liner failure we diagnose, and sweeping alone cannot restore acid-eaten tile. Call (866) 884-9512 for a video inspection — we’ll show you exactly what’s happening inside your flue.
Most 1950s Hicksville chimneys need a liner replacement, not a full rebuild, provided the exterior masonry is sound and the structure hasn’t shifted. Robert Garcia evaluates this with a combined interior video scan and exterior condition assessment; if mortar joints are tight, bricks aren’t spalling, and there’s no visible lean, we’ll recommend liner installation and crown repair rather than reconstruction. Schedule an inspection for a definitive answer — estimates are free.
Yes — the vast majority of Hicksville liner installations are performed by dropping a continuous stainless or flexible liner down the existing flue from the top, with no structural demolition required. We remove damaged clay tile through the cleanout or break it carefully in place if it’s fully detached, then thread the new liner through and seal it at the crown and appliance connections. Most jobs are completed in a single day with no interior disruption.
Salt-laden air accelerates mortar joint erosion on exterior brick chimneys, which means properties closer to Long Island Sound or with eastern exposure near major corridors like Jericho Turnpike may see faster deterioration than inland locations. We account for this in our rebuild specifications, using Type S mortar with higher cement content and recommending copper or stainless flashing over galvanized materials for longer service life in Hicksville’s coastal environment.
We install DuraFlex flexible liners and Olympia Chimney rigid systems, both 316Ti or AL29-4C stainless alloys rated for condensing appliance exhaust in high-humidity environments like Nassau County. For salvageable clay flues with minor cracking, we apply HeatShield cerfractory resurfacing, which creates a monolithic, acid-resistant interior surface. These are the same products we specify for coastal New York conditions where condensation and salt air create a harsher operating environment than inland installations.
