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.
Fast, Reliable Fireplace Services Across Jericho
Fireplace service in Jericho typically runs $180-$650 depending on whether you need a routine cleaning, gas-log adjustment, or full liner replacement, and most appointments are completed in a single visit. Our technicians are already working in Nassau County most days of the week, so Jericho properties from the split-levels near Cantiague Lane to the colonials off Jericho Turnpike are within our regular route. Call (845) 757-0998 and a live person will answer, 24 hours a day.
We’ve been serving this market for over 42 years, and we’ve learned that Jericho homes reward patience and punish shortcuts. The post-war colonials and raised ranches built during the 1950s-1970s suburban boom here weren’t designed for today’s gas inserts and high-efficiency appliances. Their masonry chimneys are now 50-70 years old, and the original clay tile flue liners are reaching the age where they crack, spall, and fail just as homeowners are adding gas-log sets and fireplace inserts they assume will “just work” in old flues. They won’t - not without inspection, and not without honest documentation of what the chimney can and cannot safely vent.
That’s why our Fireplace Services team treats every Jericho property as a unique system. We don’t brush and run. We photograph, we permit, and we explain.

Why Hearthstone Chimney Co. Is Jericho’s Preferred Fireplace Services Company
Jericho homeowners call us back because we document what we find and stand behind what we do. Our 90-Day Done Right Promise is in writing, with no arguing - if it’s not right, we come back. That matters in a hamlet where the median home value supports careful stewardship, not quick fixes.
Our reviews from Jericho customers consistently mention the same things: the technician arrived in a marked truck and uniform, explained the camera footage in plain English, and the price matched the estimate exactly. No surprises on the bill. That’s the square deal we offer.
Dispatch and scheduling are coordinated from our New York City office, but our crews serve Jericho locally and know the area. We understand the freeze-thaw cycle that hits Nassau County chimneys harder than points south, and we’ve seen what nor’easter-driven rain does to aging mortar joints on Jericho colonials that sit exposed through winter. When you call (845) 757-0998, you’re talking to someone who can get a technician to your property without a geography lesson.
We also know the local landscape well enough to anticipate problems. Properties near the Jericho Turnpike corridor, the subdivisions off Cantiague Lane, and the larger lots toward Old Westbury all present different chimney configurations - single flue, double flue, or multiple independent stacks - and we come prepared for what your house actually has.
Our Fireplace Services in Jericho
Gas Fireplace Service
Gas fireplaces in Jericho are often retrofitted into wood-burning masonry chimneys that were never designed for them. The venting requirements differ, the draft patterns differ, and the inspection protocol differs. We service gas-log sets, direct-vent inserts, and vent-free units, checking burner orifices, pilot assemblies, and - critically - the flue condition that carries exhaust gases out of your home.
In Jericho’s 1960s and 1970s split-levels, we regularly find gas-log sets installed in basement fireplaces that share a chimney stack with the main-floor wood burner. Two appliances, one masonry column, and often only one flue ever inspected. We inspect both. Every time.

Wood Burning Fireplace
Jericho’s original wood-burning fireplaces are aging gracefully in some homes and dangerously in others. The clay tile flue liners installed in the 1950s-1970s are now past their designed service life, and Nassau County’s harsh freeze-thaw cycle accelerates the spalling and cracking that lets creosote penetrate masonry and lets combustion gases leak into wall cavities.
Our wood-burning service includes a Level-2 camera inspection, professional-grade sweeping with rotary equipment, and a written verdict on liner condition. If the liner is failing, we explain exactly what we see, show you the photos, and discuss relining options using HeatShield or DuraFlex - never builder-grade substitutes.

Fireplace Insert
Inserts are popular in Jericho for good reason: they improve efficiency and reduce particulate emissions. But an insert is only as safe as the chimney that vents it. We install and service wood-burning inserts, pellet inserts, and gas inserts, with particular attention to the liner transition - the connection between insert collar and flue liner that so often gets botched by installers who don’t understand the appliance’s specific venting requirements.
Many Jericho homeowners are on their second or third insert in the same chimney. Each installation leaves its mark. We assess the cumulative condition and recommend relining when the existing flue can’t support another adaptation.

Damper Repair
A stuck or rusted damper wastes energy and can prevent proper draft. In Jericho’s older chimneys, we find throat dampers corroded shut from decades of moisture intrusion, top-sealing dampers with failed cables, and - in homes that converted to gas - dampers that were improperly locked open or bypassed entirely. We repair and replace dampers with Gelco and Olympia Chimney hardware, sized to your flue and your fuel type.

Firebox Repair
The firebox is where combustion happens, and its refractory panels or brick lining take the direct heat. In Jericho homes with 50+ year-old fireboxes, we see cracked refractory, deteriorated mortar, and heat-compromised brick that can allow flames to reach framing members. We repair with HeatShield refractory restoration or full firebox rebuild when the damage exceeds what patching can safely address.

Fireplace Conversion
Converting a wood-burning fireplace to gas is common in Jericho, but the chimney must be evaluated for gas-appliance venting before any conversion begins. Gas burns cooler and wetter than wood, producing different condensation patterns that can accelerate deterioration in an already compromised liner. We assess, we permit through Town of Oyster Bay when required, and we install only after the flue is proven suitable or properly relined.

Trusted Brands We Service in Jericho
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - brands that hold up in real chimneys, not just on specification sheets. For Jericho customers, this means we stock common liner diameters, damper sizes, and cap configurations locally, so most repairs don’t wait on freight. When a Cantiague Lane colonial needs a DuraFlex liner drop or a Jericho Turnpike property needs a Gelco damper replacement, the part is already on the truck or available within a day. No chasing, no substitutions, no “close enough.”
Common Fireplace Services Problems We See in Jericho Homes
- Multi-flue properties inspected as single-flue systems. Many Jericho custom homes and even some larger split-levels have two or three separate flues under one roofline. A technician who cleans the main fireplace and ignores the basement gas-log set or the master-bedroom insert leaves active hazards unexamined. We map every flue and inspect every appliance.
- Spalling clay tile liners brushed until they collapse. Original 1950s-1970s liners in Jericho are fragile. Aggressive brushing of a liner that’s already shedding tile fragments can turn a repairable spall into a full tear-out. Our camera inspection precedes any mechanical work.
- Gas inserts venting through damaged liners. The convenience of a gas-log set masks the condition of the flue carrying its exhaust. Carbon monoxide doesn’t smell, and a partially blocked or cracked liner won’t announce itself until it’s dangerous. We test draft and inspect visually on every gas appliance.
- Unpermitted reline work in Town of Oyster Bay jurisdiction. Jericho’s tight subdivisions have engaged homeowners who know the permit process and will report unpermitted work. We pull permits for every liner replacement and significant repair, post them as required, and schedule inspections before we call the job complete.

FAQs - Fireplace Services in Jericho
Yes. We inspect every flue and every appliance in a single appointment, and we charge for the work we do, not the number of trips. On a 1968 split-level off Cantiague Lane, the homeowner called for a routine cleaning on the main fireplace but mentioned the lower-level gas-log set smelled odd on first fall use; our tech found two separate flue systems under one masonry stack, with the original clay tile flue liner serving the wood-burning fireplace already spalling and the gas insert flue coated in third-degree creosote glaze that no brush could touch. We pulled a Town of Oyster Bay permit, sealed the wood flue with HeatShield, dropped a DuraFlex liner into the gas-appliance chase, and returned a week later to confirm draft on both before the first cold snap - a job that would never have been caught by a single-flue cleaning. Call (845) 757-0998 to schedule a full-property inspection.

Gas appliances produce carbon monoxide, water vapor, and acidic condensation that damage flue liners differently than wood creosote but just as seriously. In Jericho’s 50-70 year-old chimneys, the original clay tile liners are already at end-of-life, and the cooler, wetter exhaust from gas accelerates spalling and mortar deterioration. A gas fireplace without a sound liner can leak exhaust into wall cavities or fail to draft properly during wind events common to exposed Nassau County properties. We camera-inspect every gas appliance flue and test draft before signing off. Call (845) 757-0998 to book.

Yes. Town of Oyster Bay requires permits for liner replacements and significant chimney repairs, and inspectors are active in Jericho’s tight, well-watched subdivisions. In Jericho’s tight, well-watched subdivisions, a neighbor can and will call Town of Oyster Bay code enforcement the moment a reline job runs without the required permit - so every multi-flue job here gets permitted and posted before we pull a single tile. We handle the permit application, scheduling, and inspection sign-off as part of our standard process. Skipping this step risks a stop-work order mid-project and complicates future home sales. Call (845) 757-0998 and we’ll walk you through what your specific job requires.

Those white patches are efflorescence, mineral salts left behind when water migrates through masonry and evaporates at the surface. They’re a symptom, not the disease. In Jericho’s climate, efflorescence means water is getting into your chimney structure - through cracked crown mortar, deteriorated flashing, or spalling brick - and that water will eventually compromise the liner, the firebox, and potentially adjacent framing. We trace the water source, repair it, and assess whether the interior damage requires intervention. Some cases need only crown sealing and repointing; others reveal liner failure that demands relining. Camera inspection tells the difference. Call (845) 757-0998 for a free evaluation.

No. Frequency of use affects creosote buildup, but it doesn’t stop the freeze-thaw cycle from cracking your liner, stop water from intruding through a failed crown, or stop a gas insert from producing carbon monoxide through a compromised flue. Jericho’s chimneys are 50-70 years old. Age, not use, is the primary risk factor at this stage. An annual inspection catches deterioration before it becomes dangerous or expensive, and our Level-2 camera documentation gives you a dated record of condition that protects your home value and your family’s safety. The $280-$380 cost of inspection is minor against the cost of a chimney fire or unpermitted repair discovered at sale. Call (845) 757-0998 to schedule.
