Fast, Reliable Chimney Liner & Rebuild Across Malverne
Chimney liner installation and rebuild in Malverne typically runs $2,800–$7,500 depending on whether you need a stainless steel reline or a full masonry rebuild, and most jobs are completed in one to two days. Apex Chimney Cleaning Greater New York responds to Malverne calls within 24 hours, and Robert Garcia handles the inspection and work himself — not a subcontractor you haven’t met.
We’ve been working in Malverne’s 11565 ZIP code long enough to know what separates a quick liner job from a full stack rebuild. The village’s 1920s–1950s housing stock — Cape Cods along Norwood Avenue, Tudors near Malverne Avenue, Colonials off Hempstead Avenue — was built with chimneys sized for coal and oil furnaces, not modern gas inserts or EPA-certified wood stoves. That mismatch drives most of the liner failures we see here. If your Malverne home still has its original chimney and you’ve converted fuels or added a fireplace insert, there’s a strong chance the flue is undersized, unlined, or running on cracked clay tiles. Call (866) 884-9512 for a free camera inspection and estimate.
Why Apex Chimney Cleaning Greater New York Is Malverne’s Preferred Chimney Liner & Rebuild Company
Our Chimney Liner & Rebuild team has completed hundreds of liner installations and rebuilds across Nassau County’s South Shore, and Malverne represents a significant share of that work. The village’s aging masonry chimneys — single-wythe brick stacks with original clay liners — fail in predictable patterns that 17 years of chimney-only focus has taught us to diagnose quickly.
Robert Garcia, our owner and lead technician, personally carries out every Malverne inspection. Customers in Malverne don’t get a dispatched crew with a checklist — they get the decision-maker on the roof, the person who can authorize a scope change on the spot if the camera reveals collapsed mortar or spalled brick hidden inside the flue. That accountability shows in our numbers: 1,096 verified reviews averaging 4.7 stars, with Malverne homeowners specifically citing the thoroughness of our camera inspections and the clarity of our upfront pricing.
We’re typically on-site in Malverne within a day of your call, sometimes same-day for urgent situations like a blocked flue or visible chimney damage after a storm. Our trucks carry DuraFlex stainless steel liner stock, Gelco caps, and Olympia Chimney components, so most Malverne jobs don’t wait on parts.
Our Chimney Liner & Rebuild Services in Malverne
Stainless Steel Liner Installation
This is the standard solution for Malverne’s fuel-conversion jobs. Nearly every chimney built here between 1925 and 1960 was originally sized for a coal or oil furnace, so today’s homeowners converting to gas inserts often find the flue is undersized and unlined or has cracked clay tiles, requiring a full stainless steel liner installation rather than a simple reline. We install DuraFlex and Olympia Chimney stainless systems rated for the specific appliance — gas, wood, or pellet — and we size the liner to NFPA 211 standards, not to what fits easiest. A properly sized stainless liner in Malverne runs $2,800–$4,500 for a typical single-flue chimney, including the top plate, connector, and insulation wrap where required.
Flexible Liner Systems
Malverne’s older chimneys often have offsets — slight bends built into the stack during original construction — that rigid stainless pipe can’t navigate. For these jobs, we use DuraFlex flexible liner that bends around offsets while maintaining the full cross-sectional area your appliance needs. Flexible liners also handle the thermal expansion better in Malverne’s climate, where winter freeze-thaw cycles stress rigid connections. Expect $3,200–$5,000 for a flexible liner installation with offset navigation in a Malverne Cape Cod or Colonial.
Liner Replacement
When an existing metal liner has corroded through or a clay liner has collapsed, removal and replacement is the only safe option. In Malverne, we see premature metal liner failure from salt-laden air — uncoated or thin-gauge steel can rust through in 5–7 years on the South Shore, versus 15+ years inland. We replace these with properly insulated stainless systems and inspect the surrounding masonry before the new liner goes in. Liner replacement in Malverne typically costs $3,500–$5,500, depending on whether we need to rebuild the top courses of brick to get a sound anchoring surface.
Partial Chimney Rebuild
Many Malverne chimneys need more than a liner — they need the top 4–6 courses rebuilt, a new crown poured, and sometimes new flashing before any liner work makes sense. We call this a partial rebuild, and it’s common in Malverne where nor’easters have hammered the south-facing rooflines and salt air has eroded mortar joints for decades. A partial rebuild with liner installation runs $4,500–$7,500 in Malverne, depending on scaffold requirements and the extent of brick replacement needed.
Full Chimney Rebuild
When the stack is compromised below the roofline — spalled brick, leaning, or internal collapse — we rebuild from the foundation up or from the attic floor to the top. Full rebuilds in Malverne’s 11565 ZIP code average $8,500–$14,000, with the variance driven by height, access, and whether we’re matching historic brick for a village aesthetic review. Robert Garcia oversees every full rebuild personally, from tear-down to final liner connection.

Trusted Brands We Service in Malverne
We install professional-grade materials from Gelco, Olympia Chimney, and Famco — the same lines specified by commercial contractors and municipal building departments. Our trucks stock DuraFlex liner components, Gelco stainless caps, and Famco flashing kits, which means Malverne customers aren’t waiting a week for parts to ship. We specify coated or 316Ti stainless for Malverne’s salt-air environment, not the standard 304 alloy that corrodes faster within three miles of the Atlantic. That material choice adds maybe 10–15% to liner cost but doubles service life on the South Shore.
Common Chimney Liner & Rebuild Problems We See in Malverne Homes
- Salt-air corrosion of metal liners and flashing. Situated on Long Island’s South Shore roughly 3–4 miles from the Atlantic and Great South Bay, Malverne chimneys are exposed to salt-laden air that accelerates mortar joint erosion and metal flashing corrosion faster than inland Nassau County towns. Uncoated steel liners installed by budget operators often fail within 5–7 years here.
- Portland cement repointing debris clogging flues. A tech working Malverne regularly finds that the original oil-furnace chimney flue — often shared by the furnace and a fireplace — was repointed at some point with Portland cement mortar (too hard for brick movement), which cracks and falls inward, meaning the sweep often pulls debris that is crumbled mortar, not just creosote, and the homeowner needs a camera inspection before assuming the flue is clear.
- Nor’easter-driven rain destroying clay tiles through crown cracks. Original clay tiles, already brittle from decades of thermal cycling, are further weakened by nor’easter-driven rain seeping through crown cracks, causing tiles to spall and collapse — a common finding during any sweep in Malverne’s older homes.
- Undersized flues from fuel conversions. The 1938 Tudor on Malverne Avenue we recently worked on had an original clay liner cracked from decades of salt-air exposure and a previous Portland cement repoint that had fallen inward. The owner wanted to install a gas insert, so we pulled out the collapsed mortar debris, camera-inspected the flue, and ran a new DuraFlex stainless steel liner from top to bottom — a job that turned from a routine reline into a full rebuild inside the stack.

FAQs — Chimney Liner & Rebuild in Malverne
Most Malverne chimneys were built for coal or oil furnaces with flues that are too small, unlined, or lined with cracked clay tiles that can’t be salvaged. A “reline” assumes a sound existing flue to line over; Malverne’s original clay is usually too deteriorated from salt-air exposure and thermal cycling to provide that base. Call (866) 884-9512 and we’ll camera-inspect to confirm whether your flue can be relined or needs full replacement.
Salt-laden air from the Atlantic and Great South Bay accelerates corrosion of uncoated metal liners and flashing, leading to premature failure within 5–7 years if standard 304 stainless or galvanized steel is used. We specify coated or 316Ti stainless for Malverne installations specifically to counter this. If your current liner is showing rust at the cleanout or cap, it’s likely salt damage — call for an inspection.
Yes, especially if Portland cement was used. Portland cement is too rigid for the thermal movement of Malverne’s single-wythe brick chimneys; it cracks, falls inward, and clogs the flue with debris that looks like creosote but is actually failed mortar. We regularly pull pounds of this material from Malverne chimneys during sweeps. A camera inspection distinguishes mortar debris from creosote and reveals whether the underlying flue is intact.
We check three things: flue sizing against the stove’s output rating, structural integrity of the brick and mortar, and whether the existing liner (if any) can handle wood-burning temperatures. Most Malverne Cape Cods need a new insulated stainless liner sized to the stove, plus verification that the chimney isn’t shared with a furnace in a configuration that violates code. Robert Garcia handles this evaluation personally — call (866) 884-9512 to schedule.
Cracked or collapsed clay tile liners hidden by decades of accumulated debris, often worsened by salt-air spalling and failed Portland cement repointing. Homeowners frequently don’t know the liner is compromised until a sweep attempts to brush the flue and the brush hangs up on broken tile or mortar chunks. The fix is almost always a full stainless steel liner replacement with a camera-verified clear flue — not a quick reline.
