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.

AfterTrusted Chimney Liner & Rebuild for Mount Vernon Homeowners
Chimney Liner & Rebuild in Mount Vernon typically costs between $1,800 for a basic stainless steel liner installation and $8,500 or more for a full chimney rebuild, with most liner replacements completed in a single day. Hearthstone Chimney Co. has been serving Mount Vernon and surrounding Westchester County communities since 1984, and our background-checked, uniformed technicians complete most liner and rebuild jobs in one visit with no-hassle upfront pricing.
We’ve worked on chimneys up and down the hills of Mount Vernon, from the older Colonials near Fleetwood to the brick row houses off Sandford Boulevard. The freeze-thaw cycles here are hard on masonry. Water gets into hairline cracks in the fall, expands when winter hits, and by spring you’ve got spalling brick and a liner that’s pulled away from the wall. We’ve seen it hundreds of times. Russell Haines started this company in 1984 with the belief that a chimney job should be explained plainly, priced honestly, and guaranteed in writing. That hasn’t changed. Our 90-Day Done Right Promise means if it’s not right, we come back and make it right, no paperwork, no arguing. Call (914) 246-5794 and a live person will answer, 24 hours a day.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is a continuous metal tube inserted down the flue to contain combustion gases and protect the surrounding masonry from heat and corrosion. In Mount Vernon, we install stainless steel liners in homes where the original clay tile liner has cracked or deteriorated, which is common in houses built before 1960. Our technicians use DuraFlex and Olympia Chimney stainless steel products, measured and cut on-site for an exact fit, and we back every installation with our 90-Day Done Right Promise.
Flexible Liner
Flexible liners are corrugated stainless steel tubes that can navigate offsets and bends in chimney flues that rigid liners cannot pass through. We recommend flexible liners for Mount Vernon homes with older chimneys that have shifted over decades, particularly in the Fleetwood and Chester Heights areas where we’ve encountered flues with multiple offsets. Our team uses professional-grade flexible products from HeatShield and Olympia Chimney, and we document the entire installation with photos you can see.
Liner Replacement
Liner replacement becomes necessary when the existing liner, whether clay tile, metal, or poured refractory, can no longer safely contain flue gases. In Mount Vernon, we replace liners that have failed due to age, chimney fires, or corrosion from condensing gas appliances, a problem we see frequently in homes that were converted from oil to gas heat in the 1980s and 1990s. We remove the damaged liner, inspect the surrounding masonry with our camera system, and install a new liner sized correctly for your appliance, with a plain-English verdict on anything else we find.
Partial Rebuild
Our Chimney Liner & Rebuild in Bronxville and Mount Vernon addresses damage confined to a specific section of the chimney with partial rebuilds, typically the top few courses of brick, the crown, or one wall that has suffered severe spalling or leaning. Mount Vernon’s exposure to coastal weather patterns off Long Island Sound accelerates deterioration at the chimney top, and we’ve rebuilt the upper sections of dozens of chimneys in the North Side and South Side neighborhoods. We match existing brick and mortar where possible, install a proper concrete crown with correct overhang and drip edge, and guarantee the workmanship for 90 days.
Full Chimney Rebuild
A full chimney rebuild is required when the structure has suffered comprehensive damage, severe leaning, or deterioration that makes partial repair unsafe or impractical. We’ve completed full rebuilds on Mount Vernon homes where decades of neglected maintenance, combined with our harsh coastal winters, left chimneys structurally compromised. Our team dismantles the chimney to the roofline or below, salvaging usable brick when appropriate, and rebuilds to current code with proper flue sizing, a new liner, and a poured concrete crown, documenting each phase with photos.
Liner Repair
Liner repair addresses localized damage without full replacement, using techniques such as HeatShield cerfractory resurfacing for clay tile flues or spot welding for metal liners. In Mount Vernon, we often repair liners in chimneys that are otherwise sound but have minor cracks, gaps between tiles, or isolated corrosion, particularly in homes that have been well-maintained with regular sweeping. We perform a Level-2 camera inspection first to determine if repair is viable, and we never recommend repair when replacement is the safer option.

Brands We Service for Chimney Liner & Rebuild
We work exclusively with professional-grade materials from manufacturers who have earned their reputation over decades in the field. Our technicians are experienced with HeatShield cerfractory resurfacing systems, which we’ve applied to restore deteriorated clay flues in Mount Vernon homes where full replacement would require significant masonry demolition. We’ve installed hundreds of Gelco stainless steel liners and caps, and we keep common Gelco components on our trucks so we’re not making a second trip. Our familiarity with Olympia Chimney products means we can source and install their full range of flexible and rigid liners efficiently, with the confidence that comes from repeated hands-on experience.
We also service and install Famco chimney caps and accessories, which we often pair with liner installations to protect the rebuilt system from water intrusion. Whether your chimney has one of these brands or another make entirely, our diagnostic process is the same: camera inspection, photos you can see, a plain-English verdict, and a written estimate with no surprises on the bill.
Signs You Need Chimney Liner & Rebuild Right Now
- Pieces of clay tile in your fireplace or cleanout. This means the original liner is deteriorating and shedding material into the flue. Those fragments can block airflow, cause dangerous backdrafting, and indicate that the liner is no longer protecting your home from heat transfer to combustible framing.
- White staining or efflorescence on exterior brick. That chalky residue is minerals left behind when water moves through the masonry and evaporates. In Mount Vernon, where we get driving rains off the Sound followed by freeze cycles, efflorescence often signals cracked mortar joints and a compromised liner system that is letting moisture penetrate.
- Rust stains on the chimney breast inside your home. Rust indicates water is getting in and reaching metal components, which means the crown, cap, or liner system has failed. If the liner itself is metal, rust may mean the liner has corroded through, allowing flue gases to contact the masonry.
- A strong smoke or tar odor when the fireplace is not in use. This suggests creosote buildup, but it can also mean the liner is no longer drafting properly due to cracks, gaps, or incorrect sizing. In Mount Vernon homes with gas conversions, improper liner sizing for the new appliance causes chronic odor problems we diagnose with our camera system.
- Visible cracks or gaps in the chimney crown or mortar joints. The crown is your chimney’s umbrella. Once it fails, water enters and accelerates every other problem. We’ve rebuilt crowns and the upper chimney courses on homes throughout the Hutchinson Parkway corridor where this damage was caught before it required full rebuilds.

How Much Does Chimney Liner & Rebuild Cost in Mount Vernon?
A typical stainless steel liner installation in Mount Vernon runs $1,800-$3,400, depending on flue height, diameter, and whether the installation requires removing an existing damaged liner. For details on how much Chimney Liner & Rebuild costs across all service types, see our pricing guide. Flexible liner installations for offset flues generally fall in the $2,200-$4,000 range. Liner replacement where we must also address surrounding masonry damage typically costs $2,800-$5,500. Partial rebuilds of the chimney top run $3,500-$6,500, while full chimney rebuilds start around $7,500 and can exceed $12,000 for tall or complex structures.
Several factors move the price. Height matters: a three-story home on one of Mount Vernon’s hills requires more liner material and longer scaffolding setup than a two-story ranch. Accessibility affects labor time. The condition of the existing liner determines whether we can insert new material or must first remove damaged components. And the appliance being served, wood-burning versus gas versus oil, dictates the liner specification.
To avoid overpaying, get a Level-2 inspection with photo documentation before committing to any work. We’ve given free second opinions on written estimates from other companies, and we’ve found cases where a full rebuild was recommended when a liner replacement would suffice, and vice versa. Our estimates are free, detailed, and come with no obligation. Call (914) 246-5794 for yours.
