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.

A Chimney Liner & Rebuild - New City typically costs between $1,800 for a straightforward stainless steel liner replacement and $8,500 or more for a full chimney rebuild involving the firebox, smoke chamber, and exterior masonry. Most liner installations and partial rebuilds are completed in a single day by our background-checked, uniformed technicians. Call Hearthstone Chimney Co. at (845) 599-0930 for a free estimate with no-hassle upfront pricing - the number we quote is the number on the invoice.
We’ve been working on chimneys in New City and the surrounding Rockland County communities for over 42 years. In that time, we’ve pulled apart and rebuilt everything from 1920s masonry fireplaces in Upper Nyack to modern prefab units in Valley Cottage. Russell Haines founded this company in 1984 on a straightforward idea: document what you find, explain it in plain English, and stand behind the work. That hasn’t changed. Every chimney liner and rebuild job we take starts with a Level-2 camera inspection. You get photos you can see, a plain-English verdict, and an estimate that breaks down exactly what needs doing now, what can wait, and why. No surprises on the bill. No paperwork games if something needs correcting - our 90-Day Done Right Promise is in writing, no arguing.
New City’s freeze-thaw cycles are hard on chimney masonry. Water gets into hairline cracks, expands when temperatures drop below 20 degrees, and opens those cracks into real structural problems. We’ve seen this pattern repeat in neighborhoods from Bardonia to Hillcrest. If your liner is cracked or your exterior brick is spalling, the fix isn’t cosmetic - it’s about keeping combustion gases where they belong and keeping your home safe through another winter.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is a corrugated or smooth metal tube that runs from your appliance connection to the top of the flue, creating a sealed path for smoke and combustion gases. You need one when your original clay tile liner is cracked, when you’re installing a new high-efficiency appliance that requires a smaller flue, or when an inspection reveals gaps or deterioration that could allow carbon monoxide into living spaces. At Hearthstone Chimney Co., we measure every flue with a video scanner before ordering liner material - no guesswork on diameter or length. We use DuraFlex and Olympia Chimney stainless steel products, cutting and sealing each section on-site for a custom fit that meets NFPA 211 standards.
Flexible Liner
Flexible liner is a continuous, corrugated stainless steel tube that can navigate offset flues, chimney bends, and transitions that rigid sections cannot accommodate. This matters in older New City homes where chimneys were built around structural obstacles and don’t run straight from top to bottom. If your chimney has an offset near the smoke chamber or passes through a wall at an angle, flexible liner is often the only viable solution short of major masonry demolition. Our technicians have installed flexible liner in chimneys throughout Congers Chimney Liner & Rebuild projects and New Square where rigid pipe simply wouldn’t make the turn. We source from DuraFlex and HeatShield, and we pressure-test every installation before we call the job complete.
Liner Replacement
Liner replacement means removing the existing damaged liner - whether clay tile, old stainless steel, or poured refractory - and installing a new system sized correctly for your heating appliance. This becomes necessary when tiles are cracked by thermal shock, when a previous liner installation was done with incorrect sizing that causes creosote buildup, or when corrosion has compromised the liner’s integrity. In New Hempstead and Hillcrest, we’ve replaced liners that were installed by previous owners using off-brand materials that failed within five years. We document the condition of your existing liner with camera footage, explain why replacement is needed, and show you the new liner material before we begin. The old liner comes out, the new one goes in, and we verify the seal at every joint.
Partial Rebuild
A partial rebuild addresses specific failed sections of your chimney structure - typically the firebox, smoke chamber, or the upper courses of brick above the roofline - while leaving sound masonry in place. You need this when spalling brick, deteriorated mortar joints, or a cracked smoke chamber are localized rather than systemic. In Upper Nyack, we’ve rebuilt smoke chambers that were parged with outdated mortar formulations that couldn’t handle modern appliance temperatures, and we’ve replaced the top six feet of chimney on homes in Valley Cottage Chimney Liner & Rebuild projects where ice damming had destroyed the crown and upper courses. We match existing brick and mortar color where possible, and we always install a proper concrete crown with drip edge to protect the new work.
Full Chimney Rebuild
A full chimney rebuild is the complete teardown and reconstruction of your chimney from the foundation or fireplace floor to the cap, reserved for structures where damage is extensive or safety cannot be assured with partial repairs. This level of work is needed when multiple flues are compromised, when the chimney has separated from the house structure, or when decades of water infiltration have undermined the masonry throughout. We’ve completed full rebuilds in Ossining and Haverstraw on century-old chimneys that had been patched repeatedly until no sound original material remained. Our rebuilds use new firebrick in the firebox, properly engineered smoke chamber dimensions, and exterior masonry tied to the structure with wall ties. Every full rebuild gets a new stainless steel liner and a poured concrete crown as standard.
Liner Repair
Liner repair is the targeted restoration of a liner that is fundamentally sound but has localized damage - cracks in a few clay tiles, minor gaps at joints, or surface deterioration in a stainless steel liner. This can be appropriate when the damage is caught early and the surrounding liner material is in good condition. We use HeatShield cerfractory sealant for clay tile joints and small cracks, a product that cures to a ceramic-hard finish rated for flue temperatures. For stainless steel liners with isolated corrosion or joint separation, we can often cut out the damaged section and splice in new material without replacing the entire run. We never recommend repair over replacement unless we can show you camera evidence that the surrounding liner will last. If we can’t stand behind it, we won’t suggest it.

Brands We Service for Chimney Liner & Rebuild
We’ve installed and serviced hundreds of DuraFlex liner systems across Rockland County, from straightforward straight flue runs in New City colonials to complex installations with multiple bends in older homes near Congers Lake. DuraFlex’s 316Ti stainless steel construction holds up to the acidic condensate produced by modern gas appliances, and we keep common diameters and termination components in stock so we’re not waiting on freight when your job is scheduled.
Olympia Chimney and Famco are our go-to sources for rigid stainless steel liner components, chimney caps, and specialty termination hardware. Olympia’s smooth-wall liner reduces creosote accumulation compared to corrugated alternatives, which matters for wood-burning installations in Sleepy Hollow and Briarcliff Manor where homeowners burn cordwood through the heating season. Famco’s adjustable caps and draft-inducing terminals solve downdraft problems we’ve diagnosed in hillside homes from Upper Nyack to Valley Cottage. We also work with Copperfield supply for refractory materials and specialty tools, and with HeatShield for cerfractory repair applications. Whether you have one of these brands already or need guidance on what’s right for your system, we can help - and we’ll show you exactly what we’re proposing before any work begins.
Signs You Need Chimney Liner & Rebuild Right Now
- White staining or efflorescence on exterior brick means water is moving through your masonry and carrying dissolved salts to the surface. In New City’s climate, this freeze-thaw cycling accelerates every winter, turning minor moisture intrusion into spalling brick and compromised mortar joints. If you’re seeing white powder on your chimney exterior, the masonry is already saturated and the liner inside may be taking damage too.
- Flakes or pieces of clay tile in your firebox indicate that your original liner is deteriorating. Those tiles are your flue’s protective layer; when they crack and fall, combustion gases can reach the surrounding brickwork. We’ve found tile fragments in fireplaces from Bardonia to New Square where homeowners didn’t realize their liner had failed until we showed them the camera footage.
- Smoke or odors entering your living space when the fireplace or heating appliance is running means your chimney isn’t drafting properly. This can be a liner sizing issue, a smoke chamber problem, or a breach in the liner allowing smoke to leak into wall cavities. Carbon monoxide is odorless and invisible; if you’re smelling smoke, the same pathway may be allowing CO infiltration. This warrants immediate inspection.
- Visible cracks in the firebox brick or mortar expose the structural masonry behind to direct flame and heat. Firebox cracks don’t heal themselves - they widen with thermal cycling until the surrounding structure is compromised. In homes around Hillcrest and New Hempstead, we’ve rebuilt fireboxes where delayed repair had allowed heat to damage the adjacent framing, turning a $2,400 job into an $8,000 reconstruction.
- Your chimney crown is cracked or missing pieces and water is entering from the top. The crown is your chimney’s umbrella; without it, rain runs straight down the flue and saturates everything inside. A damaged crown is often the first domino - water gets in, liner deteriorates, masonry weakens, and you’re facing a full rebuild that could have been prevented with timely crown repair or replacement.
Our Chimney Liner & Rebuild Process - Step by Step
- 1
Schedule and confirm. Call (845) 599-0930 and a live person will answer, 24 hours a day, 7 days a week. We’ll ask about your chimney’s age, the symptoms you’re seeing, and what type of heating appliance you have. We schedule a two-hour arrival window and call 30 minutes before we arrive - we’ll be there when we say.
- 2
Level-2 camera inspection. Our technician runs a high-resolution video camera through your entire flue system, from firebox to cap. You watch the feed in real time on a tablet. We document cracks, gaps, creosote buildup, and structural conditions with timestamped photos. This isn’t a sales tool - it’s the evidence we both need to decide what actually needs doing.
- 3
Plain-English verdict and upfront estimate. We sit down with you and explain what the camera showed, what it means for safety and function, and what options you have. If the liner is cracked but the masonry is sound, we’ll say so. If we’re recommending a rebuild, we’ll show you exactly why. The estimate breaks out labor, materials, and any options. The number you approve is the number on the invoice.
- 4
Professional installation or rebuild. Our background-checked, uniformed technicians arrive with the materials and tools for your specific job - no running to the supply house mid-project. For liner installations, we drop the new system, make all connections with proper fasteners and sealants, and verify draft performance. For rebuilds, we work methodically, protecting your property with drop cloths and daily cleanup. Most jobs are completed in a single visit.
- 5
Final inspection, documentation, and warranty. We run the camera again to verify the new liner or rebuilt section. You get a photo report showing the completed work. We register your 90-Day Done Right Promise in writing - if anything isn’t right, we come back and make it right, no paperwork, no arguing. Done right, and we stand behind it.
How Much Does Chimney Liner & Rebuild Cost in New City?
A typical stainless steel liner installation in New City runs $1,800 to $3,400 depending on flue height, diameter, and whether the installation requires navigating offsets or multiple appliance connections - see how much Chimney Liner & Rebuild costs for a full breakdown. Flexible liner installations in older homes with complex flue geometry typically fall between $2,200 and $4,100. Liner replacement involving removal of existing damaged material adds $400 to $800 for extraction and disposal. Partial rebuilds - smoke chamber parging, firebox reconstruction, or upper course replacement - range from $2,800 to $6,500 depending on the extent of masonry involved and whether matching brick needs to be sourced. A full chimney rebuild in the New City area typically starts at $7,500 and can reach $15,000 or more for multi-flue structures with significant height or complex crown and flashing requirements.
Several factors move these numbers. Accessibility matters: chimneys on steep roofs or with limited staging area take more time. The condition of the existing structure affects whether we can anchor new work or need to rebuild from a lower point. Material costs for matching historic brick or specialty refractory products can add expense. And the appliance type - wood-burning, gas, or oil - determines liner specification and sizing requirements.
To avoid overpaying, get a second opinion on any estimate over $2,500. Hearthstone Chimney Co. offers a free second opinion on any written estimate from another company - bring us their paperwork and we’ll review it against what our camera inspection shows. We also recommend asking any contractor to show you camera evidence of the problem they’re proposing to fix. If they can’t or won’t, that’s information too.
Our free estimates include the Level-2 camera inspection, the photo report, and a written breakdown of recommended work with priority ranking - what’s safety-critical now, what should be scheduled within the season, and what can be monitored. There’s no obligation and no pressure. Call (845) 599-0930 to schedule.
