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.

Why Hearthstone Chimney Co. Is Yonkers’s Preferred Fireplace Services Company
We’ve been serving this region for over 42 years, and Yonkers’s chimneys have taught us lessons no classroom could. The city’s dense concentration of attached brick multi-family housing - particularly in Park Hill, Nodine Hill, and the southwest downtown corridor - means we routinely encounter shared party-wall flue stacks that were converted from coal to oil to gas across successive decades without proper relining. That layered fuel-conversion history inside aging urban masonry is far more prevalent here than in neighboring Westchester suburbs like Scarsdale or Bronxville, making liner integrity the defining safety issue for Yonkers fireplace work.
Our Fireplace Services in Yonkers team documents every inspection with photos and a plain-English verdict. No recommendation without camera evidence you can see for yourself. The 90-Day Done Right Promise backs every job in writing - if it’s not right, we make it right, no paperwork and no arguing. Background-checked, uniformed technicians. Most jobs done in one visit. A square deal: no surprises on the bill.
Our Fireplace Services in Yonkers
Wood Burning Fireplace Service
Yonkers’s Hudson River corridor channels cold northerly winds that create back-draft conditions in river-facing fireplaces, accelerating creosote accumulation beyond what inland Westchester homeowners experience. Westchester’s heavy freeze-thaw cycling each winter is especially hard on the century-old clay flue tiles and lime-mortar joints common throughout Yonkers, producing cracked liners that require relining rather than simple cleaning. We inspect with a Level-2 camera, show you the footage, and distinguish between first-degree creosote that brushes clean and third-degree glaze that needs mechanical removal - or indicates a deeper ventilation problem. No full reline recommended off a visual glance at a clay-tile flue that a camera would show is still sound. That’s the classic Yonkers upsell we exist to counter.

Gas Fireplace Service
Many Yonkers gas fireplaces were installed into chimneys never designed for them - converted coal or oil flues with inadequate draft, undersized liners, or no liner at all. In pre-1940 rowhouse blocks, one exterior brick chase often holds three or four separate flues serving different units, so the real hazard is misidentification. You can be cleaning a neighbor’s stack through the wrong hole and venting carbon monoxide into the wrong apartment. Our techs trace and label each flue before touching anything. We service direct-vent inserts, vent-free units, and gas log sets, and we stock parts from HeatShield and Olympia Chimney for fast turnaround on repairs.

Fireplace Insert Installation & Service
Inserts are popular in Yonkers’s older homes because they improve efficiency without rebuilding the firebox. But installation in a shared party-wall stack demands precise flue sizing and proper termination above the roofline - especially critical when three other households depend on the same chimney chase. We measure with a camera and a laser, not a tape measure and a guess. Our inserts use professional-grade materials from Gelco and Famco, and we handle the permit coordination where required.

Damper Repair
A stuck or rusted damper is one of the most common calls we get in Yonkers, and it’s often misdiagnosed. A damper that won’t open fully traps smoke and gases; one that won’t close bleeds heated air up the flue all winter and lets downdrafts carry chimney odors into your living room. In river-facing buildings, the Hudson corridor winds compound the problem, forcing cold air past a warped or corroded damper plate. We repair throat dampers, install top-sealing dampers for better energy efficiency, and replace rusted assemblies - most in a single visit with the part on the truck.

Firebox Repair
The firebox takes the direct heat, and in Yonkers’s century-old masonry, the refractory mortar between firebricks has often deteriorated to sand. Spalling brick, cracked sidewalls, and heat-compromised mortar joints are safety issues - they let heat reach combustible framing. We rebuild with proper refractory materials, matching the original construction where possible, and we document the damage with photos before quoting any work.

Fireplace Conversion
Converting a wood-burning fireplace to gas - or updating an old oil-converted flue to a modern gas insert - is common in Yonkers’s multi-family housing. But conversion without proper liner sizing and draft testing risks carbon monoxide spillage, especially in shared stacks where neighboring units may still be venting into the same chase. We run combustion analysis, size the liner to the appliance, and verify draft under worst-case conditions before signing off.

Trusted Brands We Service in Yonkers
We work exclusively with professional-grade materials from HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes. For Yonkers customers, that means we stock common parts locally and can often complete a repair same-visit that would take a week to order through a supply house. HeatShield’s cerfractory resurfacing system lets us restore a deteriorating clay flue liner without a full tear-out, which matters enormously in rowhouses where the chimney chase is embedded in a party wall. Olympia Chimney’s stainless steel liners handle the multi-appliance, multi-fuel configurations we see in Yonkers’s converted stacks. When we quote a repair, the brand and specification are in writing - not “equivalent or substitute” language that lets a technician downgrade on the job.
Common Fireplace Services Problems We See in Yonkers Homes
- Wrong-flue cleaning in shared stacks. A sweep brushes out what looks like the fireplace flue but misses the actual appliance vent behind a drafty damper and crumbling smoke chamber - leaving dangerous buildup in a flue still in use. We camera-locate and label every flue before cleaning.
- Freeze-thaw damage to century-old clay liners. Westchester’s winter cycling cracks flue tiles and opens mortar joints, especially on the river-facing side of buildings where wind-driven moisture penetrates the masonry. Camera inspection finds it; HeatShield or stainless relining fixes it.
- Back-draft from Hudson corridor winds. Cold northerlies push down river-facing flues, creating poor combustion and accelerated creosote glazing. We diagnose draft problems with a manometer and fix them with proper termination height, chimney cap selection, or damper upgrades - not just a brush pass that ignores the root cause.
- Upsold relines on sound clay tile. A visual glance at a stained flue does not mean the tile is failed. We camera every flue before recommending reline work, and we show you the footage. If the tile is sound, we say so. Done right - and we stand behind it.

FAQs - Fireplace Services in Yonkers
Yes, and we must. On a rowhouse block off Park Hill Avenue, we opened a shared brick chase to find four flues: two converted coal-to-gas units, one oil appliance, and a fireplace with a badly spalling firebox and a clay flue liner cracked through from fifty winters of freeze-thaw. Our tech ran camera footage, labeled each flue for both households, brushed out first-degree creosote in the gas-side liners, dropped a HeatShield liner in the failed fireplace flue, and rebuilt the smoke chamber - no reline sold on anything the homeowner couldn’t see on screen. We trace, label, and document every flue in a shared stack before cleaning. Call (914) 246-5794 to schedule - we’ll coordinate access with your neighbors if needed.

Yes, because frequency of use is not the only factor. In Yonkers, Hudson-corridor back-draft conditions can deposit creosote even in rarely used fireplaces, and freeze-thaw damage to clay liners progresses regardless of burn frequency. The National Fire Protection Association recommends annual inspection for all solid-fuel appliances. Our $89 Seasonal Tune-Up includes a Level-1 inspection that catches problems before they become dangerous. Call (914) 246-5794 to book - estimates are free.

First-degree creosote is light, fluffy soot that a standard brush removes easily - common with dry hardwood and good draft. Third-degree creosote is a hard, glazed tar that adheres to flue walls like enamel, significantly increasing fire risk and requiring mechanical removal with chains or rotary tools. In Yonkers’s river-facing buildings, back-draft from Hudson corridor winds often produces third-degree glaze even with proper fuel, because poor combustion from cold air infiltration creates the conditions for it. We identify the degree with a camera and match the cleaning method to the deposit - no one-size-fits-all brush pass. Call (914) 246-5794 for an inspection that tells you which you have.

It is a repair, though it may reveal a cleaning need too. A stuck-open damper lets downdrafts carry chimney odors - creosote, moisture, animal debris - into your living space, and it bleeds heated air up the flue all winter. In Yonkers’s older chimneys, we often find the damper plate rusted, the frame warped from heat, or the linkage corroded through. We repair or replace the assembly, and if the odor source is creosote buildup from a back-drafting flue, we clean that too. Most damper repairs run $220-$450 and finish in one visit. Call (914) 246-5794 for an exact quote - estimates are free.

Usually, yes. In Yonkers’s attached rowhouses, the chimney chase is often a party wall shared with a neighbor, so demolition is the last resort. We have two primary methods: a stainless steel liner dropped down the existing flue and properly connected at top and bottom, or HeatShield cerfractory resurfacing, which applies a new refractory surface to the interior of sound-but-deteriorated clay tile. The right method depends on what the camera shows - liner condition, flue shape, and clearance to combustibles. We show you the footage and explain both options before you decide. No reline sold on a visual guess. Call (914) 246-5794 to schedule a Level-2 inspection with camera - estimates are free.
