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 Chimney Liner & Rebuild Across Pleasantville
Chimney liner replacement and partial rebuilds in Pleasantville typically run $2,800-$7,500 depending on flue count, access, and whether the stack needs structural masonry work. Most liner jobs are completed in a single visit, and we dispatch to Pleasantville from our New York City office with crews that know the village’s specific housing stock.
We’ve been working on Pleasantville chimneys for over 42 years. We know the 1920s Colonials near Bedford Road, the Tudor Revivals along Manville Road, and the Craftsman-era homes tucked behind the village center. These houses share one thing: original masonry chimneys built for oil and coal heat, now asked to vent modern gas appliances they were never designed for. That mismatch causes damage you cannot see from the outside. We find it with a camera, show you the footage, and fix only what needs fixing. Call (914) 603-1360 - a live person answers, 24 hours a day.
Why Hearthstone Chimney Co. Is Pleasantville’s Preferred Chimney Liner & Rebuild Company
Pleasantville homeowners call us because we document before we recommend. Every Chimney Liner & Rebuild starts with a Level 2 camera inspection that ends with photos you can see and a plain-English verdict. No camera evidence, no sales pitch.
Our technicians are background-checked, uniformed, and complete most jobs in a single visit. We show up when we say we will, and the price on the estimate is the price on the invoice. The 90-Day Done Right Promise covers every liner and rebuild job in writing - if it’s not right, we make it right, no arguing, no paperwork chase.
Calls are answered by a live person, every hour of every day. Not a voicemail. Not a callback queue. A real person who can get a crew to Pleasantville.
We know the local conditions that age chimneys here faster than in other Westchester markets. The sustained freeze-thaw cycling in these rolling hills, the damp winters that run from October through April, and the specific problem of oversized oil-era flues converted to gas venting - these are not abstract hazards to us. We see them weekly on Pleasantville inspections.
Our Chimney Liner & Rebuild Services in Pleasantville
Stainless Steel Liner Installation
We install DuraFlex and Olympia Chimney stainless steel liners in Pleasantville’s older masonry stacks. These are not builder-grade substitutes. A properly sized stainless liner seals the flue, insulates it, and restores draft for modern gas appliances venting into chimneys built for oil heat. On a recent job near the Pleasantville train station, a 1930s Colonial had a gas furnace dumping exhaust into an oversized terra cotta flue running cold enough to condense moisture inside the stack. We measured, showed the homeowner the camera footage of spalling clay tile and soft mortar, then installed a DuraFlex liner sized precisely for the furnace’s BTU output. The stack now vents dry and hot, the way it should.

Flexible Liner for Tight Flues
Some Pleasantville chimneys have offset flues or narrow passages that rigid stainless cannot navigate. We use flexible liners from trusted manufacturers for these situations. The Craftsman bungalows near Grant Street often have chimney runs with slight offsets from settling over ninety years. A flexible liner follows the path without breaking the flue’s integrity. We still insulate and cap it properly, and we still show you the before-and-after camera proof.

Liner Replacement
This is our most common Pleasantville service. The original clay-tile liner in a 1920s or 1930s chimney was never meant to handle the cool exhaust of a high-efficiency gas furnace. The flue runs below the dew point, condensation soaks the mortar, and the liner spalls from the inside. Homeowners smell nothing. They see nothing. The furnace still heats the house. Then a sweep runs a camera and finds the damage. We replace the liner with a properly sized stainless system, rebuild the smoke chamber if needed, and install a new cap and crown to keep water out. Most liner replacements in Pleasantville run $2,800-$4,800 for a single-flue system, $4,200-$6,500 for multi-flue stacks.

Partial Rebuild
When the liner has failed and the masonry above the roofline or around the smoke chamber has deteriorated, a partial rebuild is the right fix - not a full tear-down that costs three times as much. We see this often in Pleasantville’s 1910-1950 housing stock: the flue is shot, but the structural brick below the roofline is sound. We rebuild what needs rebuilding, reline the flue with stainless, and restore the crown and flashing. A typical partial rebuild in Pleasantville runs $5,500-$7,500. We will not recommend one without camera evidence you can see for yourself, and we will tell you plainly when the masonry is sound enough that only a liner is needed.

Trusted Brands We Service in Pleasantville
We work exclusively with professional-grade materials from DuraFlex, Olympia Chimney, Famco, and Copperfield. No builder-grade substitutes, no off-brand liners that fail in five seasons. We stock common diameters and fittings so Pleasantville jobs do not wait on parts. A DuraFlex stainless liner carries a lifetime warranty when we install it. HeatShield cerfractory foam is available for smoke chamber parging when the masonry needs sealing but not rebuilding. Gelco caps and Gelco and Copperfield flashing components handle the water intrusion that accelerates damage in Westchester’s wet winters. Every material is chosen for the specific flue, appliance, and exposure of your Pleasantville chimney - not pulled from a generic kit.
Common Chimney Liner & Rebuild Problems We See in Pleasantville Homes
- The hidden gas-conversion failure. A furnace installed in the 1980s or 1990s vents into an oversized oil-era flue that never warms up. Condensation eats the clay tile and mortar joints from inside while the homeowner sees no symptoms. We find this on Level 2 inspections in Pleasantville constantly - it is one of the most common hidden failures in this zip code.
- Spalling terra cotta above the damper. The original clay liner cracks and flakes, opening gaps where creosote and condensation leak into the masonry. In Pleasantville’s freeze-thaw climate, that moisture expands, accelerates mortar decay, and can destabilize the stack. A camera inspection spots it before collapse.
- Smoke chamber deterioration. The area above the firebox, where the flue narrows, often has thin or crumbling parging in chimneys this old. We see this in Pleasantville’s Tudor Revivals especially - the corbelled brick was never meant to handle modern firing patterns. HeatShield cerfractory foam or hand-troweled parging restores it without a full rebuild.
- Upsold rebuilds based on age alone. A sweep tells a homeowner their 1925 chimney is “too old to save” and quotes $15,000-$25,000 for a full rebuild. We have found that many Pleasantville stacks have sound structural masonry and need only a properly sized liner and targeted masonry repair. Camera evidence separates real need from sales pressure.

FAQs - Chimney Liner & Rebuild in Pleasantville
Yes, almost certainly. The original clay flue was sized for oil heat, which runs hot enough to keep the stack dry. Your gas furnace exhaust is cooler and wetter, and the oversized flue never warms above the dew point. Condensation soaks the mortar and spalls the clay tile from inside. The furnace still works, but the chimney is deteriorating invisibly. We run a camera, show you the moisture damage and any cracked tile, then size a stainless liner precisely for your furnace’s output. Call (914) 603-1360 for a free inspection - estimates are free.
Demand camera evidence you can see, and a written estimate with line-item pricing. At Hearthstone, we show you the footage on a monitor while we explain what needs fixing, what can wait, and what does not need fixing at all. We have saved Pleasantville homeowners thousands by identifying sound structural masonry that only needed a liner, not a $20,000 tear-down. If a sweep cannot show you the damage, we recommend a second opinion - ours is free on any written estimate.
We install DuraFlex and Olympia Chimney stainless steel liners for most Pleasantville jobs, with flexible variants for offset flues. Stainless is the right material for gas appliances venting into old masonry - it resists corrosion, carries a lifetime warranty, and can be insulated to maintain proper draft. We size it to the appliance, not the old flue, which is the critical detail that prevents the condensation problem from recurring.
Yes, because the bigger risk is often the heating appliance, not the fireplace. In Pleasantville’s 1910-1950 housing stock, the same chimney that vents your occasional fire also vents your furnace or boiler daily through a separate flue. That flue is where we find the hidden gas-conversion damage. An annual Level 2 inspection covers all flues, shows you the condition of each, and catches problems before a liner collapse or masonry failure forces an emergency repair. Call (914) 603-1360 to book - estimates are free.
Often, yes. Many Pleasantville chimneys have sound structural brick below the roofline and need only targeted masonry repair plus a new liner. We rebuild what is actually failed - the crown, the top courses of brick, the smoke chamber parging - and preserve what is still sound. We will tell you plainly when a partial rebuild is sufficient and when the damage truly requires a full rebuild. The camera footage decides it, not the age of the house. Call (914) 603-1360 for an honest assessment.
