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 Chimney Liner & Rebuild Company
We’ve been answering the phone with a live person for over 42 years, and that hasn’t changed. Elmsford homeowners know us because we show up when we say we will, document every inspection with photos they can see, and explain the verdict in plain English - no contractor jargon, no pressure to book.
Our technicians are background-checked, uniformed, and carry professional-grade materials from brands like DuraFlex, Gelco, and Olympia Chimney on every truck. Most liner replacements and partial rebuilds in Elmsford finish in one visit because we stock the right parts rather than ordering after the fact.
The 90-Day Done Right Promise governs everything we do: Krafted right, Every time, Your home first, Standing behind it. If it’s not right, we come back. In writing, no arguing.
Dispatch and scheduling are coordinated from our New York City office, but our crews live and work in Westchester. That matters on Elmsford’s narrow village streets and in the tight access yards behind those 1940s-1960s brick two-families where a ladder truck won’t fit.
Our Chimney Liner & Rebuild Services in Elmsford
Stainless Steel Liner Installation
A stainless steel liner is the standard fix for Elmsford’s oil-era chimneys. We install DuraFlex and Olympia Chimney stainless liners sized precisely for your gas appliance, not the oversized terracotta flue left behind from a 1960s oil boiler. In Elmsford, this is the repair we quote most often. The new liner drops from the top, connects to your appliance below, and brings the venting into compliance with Westchester County code. A typical stainless steel liner installation in Elmsford runs $2,200-$3,800 for a single-flue residential job.
Flexible Liner Systems
Some Elmsford chimney stacks have offsets or bends that a rigid liner won’t navigate - common in the older brickwork near Route 9A and the village center. Flexible liners solve that. We measure the flue with a video camera first, then spec a flexible stainless system that bends with the chimney without losing draft performance. Flexible liner jobs in Elmsford typically fall between $2,800-$4,200 when offsets or multiple bends are involved.
Liner Replacement
Full liner replacement means removing the damaged terracotta or pulling a failed previous liner, then installing a new system from top to bottom. In Elmsford, we do this when acidic condensation from a gas appliance has eaten the mortar joints between clay tiles - something we find routinely in houses near the Saw Mill River Parkway corridor where the original flue was sized for No. 2 fuel oil. Replacement cost depends on flue count and height; most Elmsford single-family jobs land between $2,500-$4,500.
Partial Rebuild
Not every damaged chimney needs to come down. When freeze-thaw cycling in the Saw Mill River valley has spalled brick faces or cracked the crown but the structural shell is sound, we rebuild the upper courses, repour the crown, and reset the cap. Partial rebuilds in Elmsford typically range $1,800-$3,200. We pair this with liner work when the flue is also compromised - one crew, one visit, one invoice.

Trusted Brands We Service in Elmsford
We don’t use builder-grade substitutes. Our trucks carry DuraFlex stainless liners, HeatShield cerfractory resurfacing products, Gelco chimney caps, and Famco hardware - the same materials specified by Westchester’s best masons. For Elmsford customers, that means no waiting on special orders. If your crown needs a Copperfield pour form or your cap is a Gelco unit torn loose in last winter’s wind, we likely have it on the truck. The number on the estimate is the number on the invoice.
Common Chimney Liner & Rebuild Problems We See in Elmsford Homes
- Oil-era flues failing gas-venting code. Elmsford’s post-WWII chimneys were built with oversized clay tile flues sized for oil boilers. When a gas appliance vents into that same liner today, it draws cold air down from the Saw Mill River valley, condenses acid, and fails Westchester code. This is why a routine sweep here so often turns into a liner replacement estimate - a mismatch that simply doesn’t exist in newer suburbs where flues were sized for gas from the start.
- Freeze-thaw damage to crowns and brick faces. Elmsford sits in the low-lying Saw Mill River valley where winter temperatures oscillate around 32°F for weeks. That cycling spalls brick faces, fractures clay tile liners, and cracks chimney crowns. A liner that passed inspection in October can leak by March.
- Storm-driven cap displacement and flashing failure. Wind funnels down the valley and drives rain into chimney stacks. Displaced caps and torn flashing let water track down the flue and show up as a ceiling stain that looks like a roof leak until we run a Level-2 inspection.
- Multiple-flue stack deterioration. Many Elmsford two-families have a single brick stack serving both a basement boiler and a living-room fireplace. When one flue fails, the other is often close behind. We inspect both, document both, and quote only what needs doing.

FAQs - Chimney Liner & Rebuild in Elmsford
Because your oversized clay tile flue was sized for a 1960s oil boiler, not your current gas appliance. When gas vents into that large terracotta liner, it draws cold air down from the Saw Mill River valley, condenses acidic moisture, and eats the mortar joints between tiles - failing Westchester code in the process. This is nearly universal in Elmsford’s post-WWII housing stock and rare in newer suburbs where flues were sized correctly from the start. Call (914) 603-1360 and we’ll run a camera to confirm exactly what you’ve got.
Look for three things: a cracked or missing chimney cap, a ceiling stain near the chimney breast, and any white efflorescence or spalled brick on the exterior stack. Elmsford’s freeze-thaw cycling and valley wind make all three more likely here than in higher, drier Westchester towns. But don’t climb the roof yourself. A Level-2 camera inspection from our Chimney Liner & Rebuild team takes 45 minutes and gives you photos you can see plus a plain-English verdict on whether that first fire is safe.
Yes, if the structural brick below the roofline is sound. We repour crowns with professional-grade forms and reset caps with proper counter-flashing. On a two-family brick house near the Saw Mill River Parkway corridor, we opened a multiple-flue stack and found the gas boiler venting into a terracotta liner originally sized for a No. 2 fuel-oil burner - acidic condensation had eaten the mortar joints between tiles. We installed a correctly sized DuraFlex stainless steel liner in the boiler flue, repaired the cracked chimney crown and displaced chimney cap, and the homeowner finally stopped seeing a ceiling stain from flashing failures on the adjacent fireplace flue. Partial rebuilds in Elmsford typically run $1,800-$3,200.
First-degree creosote is sooty, dusty, and brushes off easily - common with dry hardwood and hot fires. Third-degree is shiny, tar-like, and glazed to the flue wall; it requires chemical treatment or mechanical removal and is a genuine fire hazard. In Elmsford, we see more third-degree buildup than expected because oversized oil-era flues run too cool for gas appliances, letting creosote condense rather than vent. A camera inspection tells you which you’ve got. Call (914) 603-1360 to book one - estimates are free.
Yes. Elmsford’s low elevation and valley position mean temperatures hover around freezing for longer periods than in higher Westchester towns. Water seeps into micro-cracks in clay tile, expands when it freezes, and fractures the liner. A liner that passed inspection in fall can be cracked and leaking by spring. Post-winter inspection is a genuinely urgent need here, not a sales tactic. The 90-Day Done Right Promise covers our liner and rebuild work in Elmsford just as it does everywhere else - in writing, no arguing.
