Fast, Reliable Fireplace Services Across New Cassel
Fireplace services in New Cassel, NY typically range from $180 for damper repairs to $3,800 for full firebox rebuilds, with most standard jobs completed in a single visit. We’re Hearthstone Chimney Co., and we’ve been driving to New Cassel since 1984. From the postwar Cape Cods along Maple Avenue to the ranch homes near Prospect Avenue, we know the chimneys here because they’re the same ones we serviced decades ago. Many are still original. Call (855) 950-3861 and a live person will pick up, 24 hours a day.
New Cassel’s housing stock tells a specific story. The hamlet’s 1940s-1960s Cape Cods and ranches overwhelmingly retain original single-wythe brick chimneys with clay flue tiles, many still serving both a fireplace and an oil-to-gas converted boiler. This creates chronic condensation and acidic deposits from oversized cold flues, a problem less common in neighboring Westbury or Garden City where teardowns are frequent. If you own one of these homes, your chimney likely needs attention even if it looks fine from the street.
Our Fireplace Services team carries the parts and materials to handle legacy systems on the spot. We don’t order and return. Most calls to New Cassel from our dispatch point mean same-day or next-day arrival. And when we get there, we document everything with photos and a plain-English verdict so you know exactly what you’re looking at.

Our Fireplace Services in New Cassel
Gas Fireplace Service
Many New Cassel homeowners converted from wood to gas in the 1990s and 2000s, but the chimney work didn’t always keep pace. A gas fireplace needs proper venting, draft, and combustion-air supply, especially when it’s sharing a flue with a boiler. We inspect gas logs, valves, pilot assemblies, and venting configurations, and we test for carbon monoxide spillage. If your gas fireplace was installed without a proper liner, we’ll tell you straight and give you a price to fix it.
Wood Burning Fireplace
The original wood-burning fireplaces in New Cassel’s postwar homes were built for a different era of heating. Decades of use, combined with Nassau County’s coastal humidity and freeze-thaw cycles, have taken a toll on mortar joints and flue tiles. We perform Level-2 camera inspections that end with photos you can see and a plain-English verdict. If the flue is cracked or the firebox is deteriorated, we’ll document it and explain your options. No scare tactics. Just facts.
Fireplace Insert
A fireplace insert can transform an inefficient open hearth into a useful heat source, but installation in a New Cassel legacy chimney requires careful sizing and proper liner connection. The insert must match the flue, and the flue must be sound. We measure, we inspect, and we install inserts from trusted manufacturers with stainless steel liners sized correctly for the appliance. Done right, an insert cuts drafts and heating bills. Done wrong, it’s a safety hazard. We do it right, and we stand behind it.
Damper Repair
The original throat dampers in New Cassel’s 1950s and 1960s homes were steel castings that rust solid in our humid climate. A stuck-open damper loses conditioned air year-round. A stuck-closed damper traps smoke and carbon monoxide. We repair or replace throat dampers, and we install top-sealing dampers when the original assembly is too far gone. Most damper work is completed in one visit, with parts we carry on the truck.
Firebox Repair
The firebox, where the fire actually burns, takes the most direct heat abuse. In New Cassel’s aging chimneys, we routinely find cracked refractory panels, deteriorated mortar joints, and spalling brick that lets heat reach combustible framing. We patch what can be patched and rebuild what must be rebuilt, using professional-grade refractory materials. We’ll show you the photos and tell you which category you’re in.
Fireplace Conversion
Converting a wood fireplace to gas is one of the most common requests we get in New Cassel, but it’s not a simple hookup. The existing flue must be evaluated for proper sizing and condition, especially in homes where an oil-to-gas boiler conversion left an oversized flue behind. We handle the gas line coordination, the appliance selection, the liner installation, and the final testing. And we know the local permit requirements in Nassau County, so nothing gets held up at inspection.
Trusted Brands We Service in New Cassel
We work exclusively with professional-grade materials from industry-trusted brands. For stainless steel relining, we use DuraFlex. For firebox restoration and ceramic sealing, we use HeatShield. For chimney caps, dampers, and ventilation hardware, we stock Gelco and Famco products. These aren’t builder-grade substitutes from a big-box store. They’re the materials we trust in our own homes, and we keep them on our trucks so New Cassel customers don’t wait for special orders. When a chimney needs a part, we install what’s right, not what’s convenient.
Common Fireplace Services Problems We See in New Cassel Homes
- 80-year-old clay flue tiles cracked from freeze-thaw cycles. Nassau County’s position between the Long Island Sound and the Atlantic subjects New Cassel to repeated freeze-thaw cycles through winter, plus high year-round humidity and coastal salt air. All of this accelerates mortar joint erosion and brick spalling. Cracked flue tiles allow carbon monoxide into living spaces through gaps in single-wythe brick walls.
- Oversized oil flues left after gas conversions cause acidic condensate accumulation. Oil-to-gas conversions done in the 1980s and 1990s frequently left original oversized oil flues untouched. An undersized gas appliance venting into a large cold flue produces chronic condensation and creosote-like acidic deposits on tile walls. Nassau County inspectors flag this, and homeowner insurance companies increasingly require relining before they’ll renew.
- Decades of deferred maintenance on original spring-operated damper assemblies. The humid Nassau climate rusts steel damper hardware solid. We’ve found dampers that haven’t closed in twenty years. The homeowner just stopped using the fireplace. We replace or upgrade these with modern assemblies that actually function.
- Nor’easter-driven moisture entering open or poorly capped flues. Coastal storms tracking up the Atlantic routinely drive rain directly into uncapped or improperly capped chimneys. This worsens interior flue tile cracking season over season and accelerates deterioration of the smoke chamber and firebox. A proper Gelco or Famco cap installation stops most of this.
On a 1955 Cape Cod on Maple Avenue, we found an unlined terra-cotta flue where a 1980s oil-to-gas conversion left an oversized 8×8 flue serving a 4-inch gas boiler vent. Chronic condensation had eaten through the tile mortar joints, and the homeowner’s insurance flagged it. We relined the flue with a 4-inch DuraFlex stainless steel liner and sealed the fireplace opening with a HeatShield blanket, saving the chimney from a full rebuild.

FAQs - Fireplace Services in New Cassel
Yes, almost certainly. New Cassel’s original clay flue tiles were sized for wood fires or oil boilers, not modern gas appliances. An undersized gas vent in an oversized flue creates chronic condensation and acidic deposits that destroy the remaining tile. We install a properly sized stainless steel liner, typically 4-inch for most gas inserts, and we coordinate with your plumber or HVAC contractor for gas supply. Call (855) 950-3861 for an exact specification and estimate - estimates are free.
Probably. Smoke odor after rain in a New Cassel home usually means water is entering through cracked flue tiles, a missing or damaged chimney cap, or deteriorated crown mortar, then mixing with creosote residue. The smell is your warning that combustion gases may also be escaping through the same gaps. We perform a Level-2 camera inspection to locate the exact breach and show you the photos. Call (855) 950-3861 to schedule - we’ll know within an hour of arrival.
Most of the time, we can replace just the damper. In New Cassel’s 1940s-1960s homes, we install either a new throat damper assembly or a top-sealing damper, depending on access and condition of the smoke chamber. A top-sealing damper often makes more sense when the original frame is corroded in place. Either way, it’s typically a single-visit repair. Call (855) 950-3861 and we’ll tell you which applies to your chimney after a quick look.
Yes. Nassau County requires a permit for any fuel conversion, and the work must pass inspection. We pull the permit as part of our standard fireplace conversion service, and we coordinate the inspection scheduling. We’ve worked with Nassau County building inspectors for decades. The paperwork doesn’t delay the job. Call (855) 950-3861 and we’ll walk you through the timeline.
It depends on the extent of deterioration. Minor spalling and mortar joint erosion can be patched with HeatShield refractory sealant or targeted repointing. If the rear wall is bowed, panels are cracked through, or multiple courses of brick are compromised, partial or full rebuild is the only safe option. We photograph the damage and give you both options when they exist. Call (855) 950-3861 for a free inspection and honest assessment.
