Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

We’ve worked on chimneys along Jericho Turnpike, in the post-war neighborhoods south of Route 25, and throughout the split-level developments near the Jericho Preserve. Jericho’s housing story is unique: thousands of post-WWII colonials and split-levels built with masonry chimneys originally sized for oil-fired boilers, plus a wave of late-1990s and 2000s teardown-and-rebuild homes with factory-built fireplaces that look like masonry from the curb. That combination means generic fireplace service often misses what’s actually wrong. Our Fireplace Services team documents every inspection with photos and a plain-English verdict, so you see what we see.

Why Hearthstone Chimney Co. Is Jericho’s Preferred Fireplace Services Company
We’ve served Nassau County communities for over 42 years, and Jericho’s mix of aging oil-era chimneys and newer zero-clearance units is familiar territory. Our technicians are background-checked, uniformed, and trained to spot the difference between a traditional masonry fireplace and a factory-built unit that requires entirely different service protocols.
Every job carries our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back. No paperwork shuffle, no runaround. We also offer no-hassle upfront pricing: the number on the estimate is the number on the invoice.
Calls are answered by a live person, not a voicemail tree or callback queue. That’s been our practice for more than four decades, and it’s how we treat Jericho homeowners who remember a time when a business answered its phone.
Our Level-2 camera inspections end with photos you can see and a verdict you can understand. In Jericho, where abandoned oil-era flue liners and hidden factory-built units are common, that documentation matters more than a generic sweep-and-go.
Our Fireplace Services in Jericho
Gas Fireplace Service
Gas fireplace service in Jericho runs $180-$320 for a seasonal tune-up, which includes burner inspection, gas pressure testing, and venting verification. Many Jericho homes converted from oil to gas in the 2000s and 2010s, and we’ve found that new gas fireplaces installed into old chimney systems often vent through abandoned, oversized flue liners never meant for low-temperature gas exhaust. That mismatch causes condensation, corrosion, and draft failure. We inspect the full venting path with a camera before we sign off on any gas fireplace as safe to operate.

Wood Burning Fireplace
Wood-burning fireplace cleaning and inspection in Jericho typically costs $240-$380. Long Island’s cold, damp winters produce real creosote accumulation, and Jericho’s inland position exposes chimneys to nor’easter-driven freeze-thaw cycles that spall older mortar joints. Our techs check for this damage on every rooftop inspection. If you burn regularly through the heating season, annual sweeping is not optional - it’s what keeps creosote buildup from becoming a chimney fire hazard.

Fireplace Insert
Fireplace insert installation in Jericho ranges from $2,800-$4,500 depending on unit size, liner requirements, and whether the existing chimney needs modification. Inserts are popular in Jericho’s older colonials where the original fireplace is inefficient but the masonry is sound. We size every insert to the chimney with a proper stainless liner - often DuraFlex or Olympia Chimney components - and we never install an insert into an unlined or damaged flue. The result is a system that drafts correctly and meets manufacturer warranty requirements.

Damper Repair
Damper repair or replacement in Jericho costs $280-$520. A failed damper wastes heated air, lets cold drafts in, and can prevent proper fireplace ventilation. In Jericho’s post-war homes, we’ve found original throat dampers rusted solid from decades of oil exhaust condensation, or damaged by debris falling from deteriorated terra-cotta flue liners. We repair or replace with components sized to the original fireplace opening, and we document the condition with photos before recommending any work.

Fireplace Conversion
Fireplace conversion in Jericho - typically wood-to-gas or restoring an abandoned unit to functional use - runs $1,800-$5,500 depending on scope. This is one of the most common requests we receive in Jericho, and it’s where the town’s oil-to-gas history creates the most risk. Converting without inspecting the liner condition, sizing the venting correctly, and determining whether the chimney is shared with another appliance can create carbon monoxide hazards or code violations. We handle the full evaluation, permit guidance, and installation to Nassau County standards.

Firebox Repair
Firebox repair in Jericho ranges from $650-$2,400 for refractory panel replacement, tuckpointing, or structural rebuilding. Water intrusion from failed chimney caps or crown cracks - accelerated by freeze-thaw damage - is the leading cause of firebox deterioration we see in Jericho. We use HeatShield or similar professional-grade refractory materials, and we always trace the water source before repairing the firebox. Fixing the firebox without fixing the leak is a temporary patch, and we don’t do temporary patches.

Trusted Brands We Service in Jericho
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - no builder-grade substitutes that fail early. For Jericho homeowners, that means we stock liners, caps, dampers, and refractory components that match what your system needs, not what a supplier had on clearance. Most repairs are completed in a single visit because our trucks carry the right parts. When a 1960s Jericho colonial needs a stainless liner properly sized to a new gas insert, or a zero-clearance unit along Route 25 needs a factory-specific replacement part, we don’t order-and-wait. We fix it and stand behind it.
Common Fireplace Services Problems We See in Jericho Homes
- Abandoned oil-era flue liners left oversized and uncapped after gas conversion. These 8×13 terra-cotta liners were built for oil boiler exhaust and are dangerously oversized for modern gas appliances. Moisture, animals, and freeze-thaw cycles degrade the tile further. We find this on camera inspections in post-war colonials throughout Jericho, especially south of Jericho Turnpike.
- Factory-built zero-clearance fireplaces misidentified as masonry. The teardown-and-rebuild homes along the Route 25 corridor often have metal-framed fireplaces with refractory panels that look like brick from the living room. Homeowners call for a “chimney sweep” and get incorrect service that voids warranties or damages the unit. We identify the manufacturer and service to spec.
- Nor’easter-driven freeze-thaw spalling on older brick chimneys. Jericho’s inland position doesn’t protect chimneys from coastal storm moisture that freezes, expands, and cracks mortar joints. Corroded galvanized caps and flashing let water reach the firebox and smoke chamber. We flag this on every rooftop inspection.
- Damper failure from rust and debris in shared oil-era chimneys. Decades of sulfur-laden oil exhaust corrodes metal components and weakens throat dampers. Combined with falling tile fragments from deteriorated liners, the damper seizes or fails to seal. Repair requires addressing both the damper and the liner condition above it.

FAQs - Fireplace Services in Jericho
Yes, in most cases the original terra-cotta liner must be replaced or properly decommissioned. The 8×13 liners common in Jericho’s post-WWII homes were sized for oil boiler exhaust, not the cooler, wetter exhaust from gas appliances. An oversized liner causes condensation, corrosion, and draft failure that can spill carbon monoxide into living spaces. Our Level-2 camera inspection determines the exact condition and whether a stainless liner, direct vent, or other solution is appropriate. Call (934) 348-4832 to schedule - estimates are free.

Jericho’s specific housing history creates concentrated problems: the oil-to-gas conversion wave left thousands of chimneys with mismatched liners, and the teardown-rebuild boom along Route 25 installed factory-built units that are frequently misidentified and incorrectly serviced. Combined with Nassau County’s freeze-thaw exposure, these factors produce more liner, damper, and firebox issues than in towns with newer, uniform housing stock. Our techs know what to look for because we’ve documented it repeatedly in Jericho homes. Call for an inspection and we’ll show you exactly what your chimney needs.

Every chimney in Jericho should receive a Level-2 inspection annually if it serves a wood-burning fireplace, and every two years for gas fireplaces - or immediately after any chimney fire, earthquake, or major weather event. Given Jericho’s freeze-thaw exposure and the high incidence of abandoned oil-era liners, we recommend annual camera inspections for any home converted from oil to gas, even if the fireplace is no longer used. Unused chimneys with failed caps admit moisture and animals that cause hidden damage. Schedule your inspection at (934) 348-4832.

It may not be. Many late-1990s and 2000s teardown-and-rebuild homes along the Jericho Turnpike corridor have factory-built zero-clearance fireplaces with refractory panels that mimic brick. These metal-framed units require manufacturer-specific cleaning protocols, parts, and clearances. Incorrect service - including standard masonry sweeping or improper cap installation - can damage the unit and void warranties. We identify the manufacturer and model during our inspection and service to the correct specification. Call (934) 348-4832 to verify what you actually have.

Stainless steel caps last decades; galvanized steel caps corrode within 5-10 years in Jericho’s climate, especially with salt-laden coastal storm exposure. We’ve replaced hundreds of rusted galvanized caps on Jericho chimneys that failed prematurely and allowed water to destroy fireboxes, smoke chambers, and adjacent framing. We install only stainless caps - typically Gelco or similar professional-grade components - because replacing a cap twice costs more than doing it right once. For a cap inspection and replacement quote, call (934) 348-4832.
Our tech was called to a 1962 split-level off Jericho Turnpike where the homeowner had just converted from oil to gas heat. A Level-2 camera inspection revealed the abandoned 8×13 terra-cotta flue liner was cracked and oversized for the new gas boiler, causing draft issues and spillage. We relined with a DuraFlex stainless system properly sized to the appliance and installed a new stainless cap, restoring safe draft and closing out the oil-era mismatch.
