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 Elmsford’s Preferred Fireplace Services Company
We’ve been serving Westchester County communities for over 42 years, and Elmsford’s particular mix of aging masonry and oil-to-gas conversion history is familiar territory. Our technicians know what to expect when they pull up to a 1950s brick two-family near Route 9A: multiple flues, deferred tuckpointing, and a gas appliance venting into a terracotta liner that was sized for a fuel-oil burner decades ago.
Our Fireplace Services team documents every inspection with photos you can see and a plain-English verdict. The 90-Day Done Right Promise backs every job in writing - if it’s not right, we come back, no paperwork and no arguing. Background-checked, uniformed technicians complete most jobs in a single visit, and the price we quote is the price on the invoice.
Calls are answered by a live person, every hour of every day. Not a voicemail. Not a callback queue.
Our Fireplace Services in Elmsford
Gas Fireplace Service
Gas fireplaces in Elmsford’s converted homes often struggle because the flue is wrong for the appliance. That oversized clay tile liner installed for a No. 2 fuel-oil boiler draws cold valley air down the stack, condenses acidic moisture at the joints, and corrodes the system from inside. We run a Level 2 camera inspection, show you the footage, and tell you straight whether the flue needs relining or just a proper cap and sweep. Our gas service includes burner cleaning, pilot adjustment, and combustion testing with documented results.

Wood Burning Fireplace
The open hearths in Elmsford’s older homes were built for a different era of heating. Decades of Westchester freeze-thaw cycles have cracked crowns, spalled brick faces, and opened mortar joints that let smoke leak into wall cavities. We inspect the firebox, smoke chamber, and flue with a camera, then repair what needs repairing - firebox refractory panel replacement, smoke chamber parging, or crown sealing with flexible masonry coating. Nothing gets recommended without photo evidence you can see for yourself.

Fireplace Insert
For Elmsford homeowners tired of drafting problems and heat loss up the chimney, a fireplace insert is often the right fix. We size inserts to fit the existing opening and reline the flue with a properly sized stainless system - usually DuraFlex or Olympia Chimney components - so the appliance vents safely and efficiently. This is especially important in Elmsford’s oil-era chimneys, where the original flue is almost always too large for modern gas or wood-pellet inserts. We handle the full installation, including hearth pad, surround, and final inspection.

Damper Repair
A stuck or rusted damper wastes heat and lets cold Saw Mill River valley air pour into your living room. In Elmsford’s humid low-lying climate, we’ve found dampers frozen shut by rust, warped by heat, or clogged with fallen mortar from deteriorating throat frames. We repair or replace throat dampers and install top-sealing dampers that close at the chimney crown - a better solution for homes with persistent down-drafts.

Firebox Repair
The firebox takes the direct heat, and in Elmsford’s 60- to 80-year-old fireplaces, the refractory panels or firebrick are often cracked or deteriorated. We replace panels with HeatShield or professional-grade refractory materials rated for the temperatures your fireplace generates. Cracked fireboxes are a genuine safety issue - heat transfer to combustible framing - so we flag this immediately and show you exactly what we found.

Fireplace Conversion
Converting an open wood-burning fireplace to gas in Elmsford requires more than dropping in a log set. The flue must be assessed for proper sizing, the gas line must be routed safely, and the combustion air supply must meet Westchester County code. We handle the full conversion, from liner installation with Gelco or Famco components to final permit sign-off, and we explain every step before we start.

Trusted Brands We Service in Elmsford
We stock parts and materials from the brands that professional sweeps actually trust - no builder-grade substitutes. For Elmsford customers, that means fast turnaround on repairs using DuraFlex liners, HeatShield refractory systems, Gelco caps and dampers, and Olympia Chimney components. We carry Famco flashing materials and Copperfield masonry products on our trucks, so most jobs don’t wait for a parts run. When you’re dealing with a cracked crown before a forecast freeze, that matters.
Common Fireplace Services Problems We See in Elmsford Homes
- Wind-driven rain and displaced caps after nor’easters. Elmsford’s valley position funnels storm winds along the Saw Mill River corridor, and we’ve found chimney caps lifted or rotated on their bases, letting water pour down the flue. The water tracks through the smoke chamber and shows up as a stain on the ceiling below - sometimes months later, when the homeowner has forgotten the storm.
- Freeze-thaw crown cracking on a schedule newer suburbs don’t see. Temperatures in Elmsford oscillate around 32°F repeatedly through winter, saturating the masonry and expanding ice in micro-cracks. Crown caps fracture, brick faces spall, and the chimney degrades faster than it would at higher, drier elevations in Westchester.
- Failed flashing at the roof-to-chimney transition. The step flashing and counter-flashing on Elmsford’s older homes have often been patched rather than replaced, and severe weather opens the gap. The first sign is a brown ceiling stain near the chimney breast - by the time you see it, water has been entering for a while.
- Gas appliances venting into oversized oil-era flues. This is the near-universal finding on our Elmsford calls. The terracotta liner was spec’d for a boiler burning No. 2 fuel oil, and now a gas appliance vents into a flue that’s too large. Cold air draws back down, condensation forms acidic moisture, and the liner joints deteriorate. A routine sweep becomes a liner replacement estimate - not an upsell, a code and safety issue.

On a two-family brick home off the Saw Mill River Parkway corridor, our tech pulled a Level 2 inspection after a February nor’easter and found the chimney cap displaced by wind, a hairline crack across the crown, and water tracking down an exterior flashing joint into the ceiling of the second-floor bedroom. We reset the cap, sealed the crown with a flexible masonry coating, replaced the step flashing, and re-swept a gas-vented terracotta flue that had been drawing condensation for years - booking the homeowner a Fireplace Insert consult once the flue was verified dry.

FAQs - Fireplace Services in Elmsford
That smell is almost always down-drafting - cold air from the Saw Mill River valley being pulled down your chimney, picking up soot and creosote odors from the flue walls, and pushing them into your living room. In Elmsford’s oil-era chimneys, the oversized flue makes this worse because there’s more volume for cold air to move through. A top-sealing damper or properly sized liner usually fixes it. Call (914) 603-1360 and we’ll diagnose it with a camera.

It could be either, and often it’s both. Wind-driven rain in Elmsford’s valley corridor displaces caps and cracks crowns, while aging step flashing opens at the roof joint. Water enters at the top, travels down the masonry, and exits at the first convenient gap - usually the ceiling below. We run a Level 2 inspection to trace the exact path, show you the photos, and quote only what’s actually failed. Free estimates: (914) 603-1360.

Yes - especially here. Elmsford’s gas-converted flues deteriorate from acidic condensation whether you burn wood or not, and the freeze-thaw cycling cracks crowns and opens mortar joints on a schedule independent of fireplace use. An annual Level 2 inspection catches liner failure, cap displacement, and flashing gaps before they become interior water damage or carbon monoxide hazards. The $89 seasonal tune-up covers it.

First-degree creosote is flaky and sooty - it sweeps out easily with a brush. Third-degree creosote is hardened, glazed, and tar-like, often requiring rotary chain removal or chemical treatment. In Elmsford’s older, cooler-flue chimneys (especially those with oversized liners), combustion gases condense before exiting, which accelerates third-degree buildup. Glazed creosote is the fuel of chimney fires. We document what we find with photos and remove it completely - no shortcuts.

We can, and we do it regularly. The critical step is flue assessment: most Elmsford homes need a properly sized stainless liner installed before any gas appliance or insert can vent safely. We handle the full conversion - gas line routing, liner installation with DuraFlex or Olympia Chimney components, hearth pad, surround, and permit sign-off - and we verify the flue is dry and correctly sized before we leave. Call (914) 603-1360 for a free estimate on your specific fireplace.
