We’ve worked on Malverne chimneys for over 42 years. We know the 1920s Cape Cods near Norwood Avenue, the Tudor colonials along Hempstead Avenue, and the post-war bungalows tucked behind the Malverne train station. These homes were built when coal and oil heat were standard, and their chimneys tell that story in the mortar, the liner size, and the flue configuration. That history matters when we’re diagnosing what’s wrong and what it’ll take to fix it right.

Our Fireplace Services in Malverne
Gas Fireplace Service
Malverne’s conversion from oil to gas heat has brought us hundreds of gas fireplace installations and service calls over the past decade. The village’s 1920s-1950s housing stock wasn’t built for gas exhaust - the original terracotta liners are oversized for high-heat oil combustion and dangerously wrong for the cooler, moisture-laden exhaust of modern gas appliances. We service direct-vent and vent-free gas fireplaces, inspect gas lines and valves for leaks, and verify proper draft before we sign off. A gas fireplace in Malverne that isn’t drafting correctly risks carbon monoxide backing up into the living space. We test with calibrated equipment and show you the readings.

Wood Burning Fireplace
The open wood-burning fireplaces in Malverne’s pre-war colonials and Capes were built for a different era of heating. Decades of Long Island’s hard, mineral-rich groundwater seeping through aging mortar joints has left many fireboxes cracked, parged surfaces crumbling, and smoke shelves deteriorated. We inspect with Level-2 camera equipment, document every defect with photos, and give you a plain-English verdict: what needs repair now, what can wait, and what it costs. If you’re burning wood in a Malverne home built before 1955, we also check for the creosote buildup that older, slower-drafting flues accumulate.

Fireplace Insert Installation
A fireplace insert - wood, gas, or pellet - is often the right solution for a Malverne homeowner with a drafty, inefficient open fireplace. But inserts require a properly sized and lined flue. In Malverne, that frequently means relining the chimney with a DuraFlex or HeatShield system before the insert goes in. We’ve installed inserts in Cape Cods near Norwood Avenue and Tudor colonials along Hempstead Avenue, and every job starts with a Level-2 inspection to confirm the flue can handle the insert’s exhaust profile. Skip this step and you’re looking at poor performance, smoke spillage, or worse.

Fireplace Conversion
This is the work that defines our Malverne calendar. When PSEG Long Island brings natural gas to a neighborhood, homeowners convert - and then discover their chimney needs serious attention. The oversized terracotta liner sized for oil can’t handle gas condensate. The shared flue between fireplace and heating plant, once legal, now violates Nassau County and New York State code. We handle the full conversion: gas line coordination, insert or direct-vent installation, chimney relining with professional-grade materials, and permit filing with the Nassau County Building Department. We took over a Malverne Tudor colonial on Hempstead Avenue where the homeowner had just decommissioned the oil tank for gas. The shared flue - once legal - now violated code, and the liner was cracked from years of salt-laden nor’easter rain. We separated the fireplace flue with a DuraFlex 316L liner and sealed the unused oil flue, passing the Nassau County inspection on the first try.

Firebox Repair
The firebox takes the direct heat, and in Malverne’s 80- to 100-year-old fireplaces, the refractory panels or parged surfaces are often failing. We rebuild fireboxes with HeatShield refractory mortar or replace cracked panels with factory-matched materials. A compromised firebox lets heat reach combustible framing - a genuine safety hazard we flag immediately. Our firebox repairs in Malverne typically run $1,800-$3,200 depending on whether we’re repointing, parging, or rebuilding from the lintel down.

Damper Repair
A stuck, rusted, or misaligned damper wastes heat and can make your fireplace unusable. In Malverne’s coastal climate, dampers corrode faster than inland. We repair or replace throat dampers, install top-sealing dampers for better efficiency, and handle the rare cases where a damper frame has warped from decades of heat cycling. Most damper repairs in Malverne are done in under two hours, with the technician still on site.

Trusted Brands We Service in Malverne
We stock and install professional-grade materials from the brands that last: DuraFlex stainless steel liners, HeatShield refractory systems, Gelco chimney caps, and Famco dampers and termination kits. For Malverne homeowners, that means no waiting on special orders for standard repairs. Our trucks carry the common sizes and configurations for the village’s typical chimney profiles, so we can often complete a cap replacement, liner connection, or damper installation without a return trip. We don’t use builder-grade substitutes. The materials we put in your chimney are the same ones we’d put in our own.
Common Fireplace Services Problems We See in Malverne Homes
- Cracked terracotta liner from freeze-thaw damage: Nassau County’s winter temperatures oscillate around 32°F repeatedly, pumping water into micro-cracks in liner tiles. In Malverne’s original oil flues, the oversized terracotta can’t handle gas condensate, accelerating spalling and cracking season after season.
- Deteriorated crown and flashing from nor’easter exposure: Malverne’s location three miles from the South Shore puts chimneys in the path of wind-driven, salt-laden rain. We’ve replaced dozens of cracked concrete crowns and re-flashed chimney-to-roof junctions on homes near Lakeview Avenue where water had been leaking for years undetected.
- Illegal shared flue surfacing during oil-to-gas conversion: Many Malverne homes ran fireplace and oil burner through a single flue - legal when built, prohibited now. When the oil tank gets decommissioned and gas comes in, that violation surfaces on inspection. Every such job requires Nassau County Building Department permitting for relining and flue separation.
- Firebox deterioration from decades of direct heat: The refractory mortar in Malverne’s pre-1955 fireplaces has often exceeded its service life. We find crumbling parging, cracked side walls, and heat-damaged lintels that threaten to let fire reach the structural framing.

FAQs - Fireplace Services in Malverne
Yes, almost certainly. The original terracotta liner in your 1940 Malverne home was sized for the high temperatures of oil combustion. Modern gas exhaust is cooler and carries more moisture, which condenses inside that oversized flue, saturates the terracotta, and destroys it through freeze-thaw cycling. We’ve relined dozens of Malverne chimneys following oil-to-gas conversions, typically with a DuraFlex 316L stainless liner properly sized for the new appliance. The job requires a Nassau County Building Department permit, which we handle. Call (855) 950-3861 for an exact quote - estimates are free.

Separate flues for fireplace and furnace are correct and current code. The problem we find in Malverne is the opposite: many older homes have one flue serving both, which was legal when built but violates present Nassau County and NYS code. When you convert to gas or sell your home, that shared flue gets flagged. We separate the systems, reline the active flue, and properly terminate the abandoned one. Call (855) 950-3861 and we’ll inspect to confirm your configuration.

Wind-driven rain found a path through your chimney’s crown, flashing, or deteriorated mortar joints. Malverne’s coastal position means salt-laden air accelerates the deterioration that lets water in. We inspect the crown for cracks, the flashing for lifted seams, and the mortar for voids - then show you photos of what we found. Most water-intrusion repairs in Malverne run $650-$1,800 depending on whether we’re repointing, recrowning, or reflashing. Call (855) 950-3861 to schedule before the next storm makes it worse.

No, not safely or to code. A gas insert requires a properly sized flue liner matched to the insert’s BTU output and exhaust temperature. Your existing terracotta liner is almost certainly the wrong size, and in Malverne’s older homes, it’s often cracked or deteriorated from decades of use and weather exposure. We install the insert and the liner as a matched system, with one permit and one crew. Typical combined cost in Malverne: $3,800-$6,500. Call (855) 950-3861 for a free inspection and exact quote.

We repair when possible, replace when necessary. Corrosion and creosote buildup can often be cleaned and the mechanism freed. If the frame is warped from heat cycling or the throat is rusted through, we install a new damper - sometimes a top-sealing model that seals tighter and saves heat. Most damper work in Malverne is completed in a single visit for $180-$450. Call (855) 950-3861 and we’ll tell you which category yours falls into.
