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 Yonkers Homeowners
A stainless steel chimney liner replacement in Yonkers typically costs $2,800 to $6,500, and a full chimney rebuild from the roofline up runs $12,000 to $28,000 depending on access and the condition of the masonry. Most liner jobs in Yonkers are completed in one day, and we protect your finished flooring and yard with ground tarps before the first ladder comes off the truck. Level Two Chimney Yonkers has documented more than 38,000 chimney inspections since 2009, every one with a written price before work started and a photo record when it was done. That practice became Clause 4 of the Haven Standard, and it’s the reason homeowners in Park Hill, Crestwood, and Lincoln Park call us when a camera scan shows a cracked terra cotta liner or a spalling crown. Call (551) 212-3526 for a no-obligation estimate with a written price.
What Our Chimney Liner & Rebuild Service Includes
Every liner and rebuild job in Yonkers begins with the same first move: a NFPA 211 Level 2 camera scan, because anything less is a guess. The camera finds the gap, the crack, or the section of disintegrating clay before we talk about a fix. You see the footage. You get a written price. You decide. That order never changes.
Stainless Steel Liner
We install rigid and flexible 316L stainless steel liners sized to the appliance and the flue’s interior dimensions, welded seams where needed and mechanically fastened at the top plate. In Yonkers, where winter freeze-thaw cycles have cracked more than a few original clay liners in older Colonials and Capes, stainless is the liner we recommend most often because it carries a lifetime warranty and doesn’t re-crack. We’re pulling liners from DuraFlex and Olympia Chimney because their steel comes with manufacturer transferable warranties we can put in writing for you. You need a stainless liner when the camera shows a cracked clay tile, missing mortar joints between tiles, or a flue that’s no longer sized correctly for the appliance it serves.
Flexible Liner
Flexible liners are single-wall stainless steel tubes that snake down through an existing flue, which means no masonry teardown and far less disruption to your finished basement or first-floor walls. They’re the right call when the original clay liner has failed but the surrounding masonry is still structurally sound. Level Two Chimney Yonkers installs flexible liners with an insulated wrap when the flue sits close to combustible framing, because Yonkers building code and NFPA 211 both require that clearance to be protected. We vacuum every flue before liner insertion, so the new liner goes into a clean chase, not one full of creosote dust from the old liner’s last season.
Liner Replacement
Liner replacement means one thing: pulling the old liner out and putting a new one in. It starts with the camera scan to see what’s actually failed, then a written scope that names the exact length, diameter, and alloy of the replacement liner, plus the top plate, rain cap, and termination height. If the old liner is clay tile, we remove the broken sections and open the chase without damaging the surrounding brick; if it’s an old steel liner, we disconnect it at the appliance, winch it out, and measure the existing chase for the correct replacement. Yonkers homeowners get a documented record of the before and after, because a liner replacement you can’t verify is just a story.
Partial Rebuild
A partial rebuild addresses the chimney above the roofline, usually from the crown down to the point where the brick is still sound. In Mount Vernon and Yonkers, we see partial rebuilds every spring after freeze-thaw has popped face brick loose from the mortar bed at the top two or three feet of the stack. We rebuild that section with type N mortar, replaced brick where needed, a poured crown with a drip edge, and flashing re-bedded into the masonry, not surface-caulked. A partial rebuild makes sense when the lower chimney structure is intact but the top is spalling, the crown is cracked through, or water has been getting in at the roofline for more than one season.
Full Chimney Rebuild
When the camera scan and a visual inspection show structural damage from the smoke shelf up through the termination, or when mortar joints from the roofline down are missing more than a third of their material, a full rebuild is the honest recommendation. We take the chimney down to the point where sound masonry remains, then rebuild with new brick and lime mortar sized for the existing footprint, reinstalling the liner, flashing, crown, and cap as one connected system. Corrine Halstead, who leads our Yonkers team, has walked more west-side rooflines than she can count, and she is the one who writes the rebuild scope you see before any brick comes down. A full rebuild in Yonkers and nearby Eastchester means scaffolding permits in some neighborhoods, and we handle that paperwork for you.
Liner Repair
Liner repair is for the cases where the damage is localized: a single cracked tile, a shifted joint, a stainless liner with a failed seam. We use HeatShield cerfractory sealing systems when the liner has minor joint failure but the overall flue is still sound, and that repair can often be completed in a single visit. You should not agree to a liner repair without seeing the camera footage first, because a patch over a structurally compromised liner just moves the fire risk further into the wall. Our repair scopes always include a follow-up camera scan after the repair cures, so you can see the sealed joint in the final photo record.

Brands We Service for Chimney Liner & Rebuild
We work with DuraFlex liners every week, from 4-inch furnace flues to 12-inch wood-burning stacks. Their flexible stainless steel is what we reach for on most Yonkers liner replacements because the alloy holds up to the high-moisture flue gases we get with older east-side boilers, and the warranty is one we can transfer to a new owner if you sell the home. We keep their top plates, termination caps, and connectors in stock, so a scheduled liner job doesn’t stall waiting on parts.
We specify Olympia Chimney rigid liners when the flue is straight or the chase is oversized, because a rigid liner has welded seams and no corrugation, which means less creosote accumulation and easier sweeping for the life of the liner. Gelco caps and chase covers round out most of our rebuilds, because their stainless and copper work holds up to nor’easter ice better than the stamped steel caps we see rusted through on older Riverdale and Kingsbridge homes. Whether you have these brands or any other make, the camera scan tells us what’s in the flue, and we quote the correct repair or replacement from there.

- Flakes of tile in the firebox. When you find thin, curved pieces of terra cotta in the firebox or on the smoke shelf, that’s a cracked clay liner shedding from inside the flue. Each missing tile is a gap between the flue and the house framing, and that’s the path a chimney fire takes out of the chimney and into the wall.
- White staining on the exterior brick. That white mineral residue is efflorescence, and it means water is moving through the chimney structure. Water plus freeze-thaw in Yonkers winters is what pushes brick faces off the stack and cracks the crown open, and once water is moving through the liner chase, the liner is already compromised.
- Draft problems that get worse, not better. If the fireplace smokes back into the room, or the boiler vent can’t hold a draft, something is physically blocking or changing the flue path. A camera scan in Yonkers most often finds a shifted tile, a bird nest, or a collapsed section of old liner, and none of those fix themselves.
- Rust on the damper or firebox walls. Rust inside the firebox means water has been running down the flue for months, not days. That water is coming in through a failed crown, missing cap, or cracked flue, and by the time you see rust, whatever is letting the water in has already started damaging the masonry from the inside.
- You can see gaps in the mortar joints from the ground. If the joints between bricks at the top of the stack look eroded, recessed, or missing entirely, the chimney is losing its weather barrier. Loose bricks and open joints are how the top of a chimney becomes a full rebuild instead of a repoint, and the sooner we document it, the smaller the written scope will be.
Our Chimney Liner & Rebuild Process - Step by Step
- 1
Camera scan first, every time. We run a NFPA 211 Level 2 camera from the appliance up to the termination, and you watch the screen with us. We note the liner material, the crack pattern, the creosote class, and the flue dimensions on a written condition report while the footage is still fresh.
- 2
Written scope with a written price. You get a line-item proposal that names every part: liner length and alloy, top plate, cap, mortar type, flashing, access notes. Nothing is verbal, nothing is “we’ll see when we get up there.” Clause 1 of the Haven Standard, in effect since 2009.
- 3
Site protection and demolition. We lay ground tarps around the chimney base and inside the house from the entry to the fireplace, then bag and lower demolition debris, never drop it. If you’re getting a full rebuild, the scaffold goes up with permits already filed.
- 4
Liner installation or masonry rebuild. The liner goes in mechanically fastened, with an insulation wrap where code requires it. Rebuilds go up in lifts, each one cured enough to hold the next, so the wall settles straight and the flashing seats properly into the mortar bed.
- 5
Follow-up camera scan and photo record. Before we pack the truck, we run the camera again so you can see the finished liner top to bottom, then hand you a digital photo record showing before, during, and after. Clause 4 of the Haven Standard, on every job, no exceptions.
How Much Does Chimney Liner & Rebuild Cost in Yonkers?
Here’s what we see with our Chimney Liner & Rebuild in Yonkers. A stainless steel liner replacement for a single-flue wood-burning fireplace runs $2,800 to $4,600, and a boiler or furnace flue liner runs $1,900 to $3,200 because the liner diameter is smaller and the run is shorter. A partial rebuild from the roofline up sits in the $6,000 to $12,000 range depending on brick condition and whether the crown needs a full repour. A full chimney rebuild in Yonkers starts around $12,000 and tops out near $28,000 on a three-story Victorian with a multi-flue stack, stucco over brick, and tight scaffold access. Liner repair with HeatShield sealer comes in lower, usually $800 to $1,800 per flue, when the damage is localized and the rest of the liner is structurally sound.
What moves the price is flue height, number of flues, scaffold or roof access, and whether the existing chase is large enough for an insulated liner or needs to be opened. The way to avoid overpaying is to get the camera scan before you get the price, because a company that quotes a liner without seeing the inside of the flue is guessing, and guessing costs you either a liner you didn’t need or a house fire you didn’t see coming. Every Level Two Chimney Yonkers estimate is free, written, and itemized. We also offer a Free Second Opinion on any written estimate, so if another company has quoted you a rebuild, bring us their written quote and we’ll tell you what we’d actually do.

Frequently Asked Questions - Chimney Liner & Rebuild in Yonkers
A chimney liner is the inner wall of the flue, the sealed path that carries smoke and combustion gases from the appliance up and out of the house. A rebuild is masonry work that replaces damaged brick, mortar, crown, or flashing on the chimney structure itself. Both come down to the same requirement: an intact, properly sized flue path that’s separated from combustible framing by the clearances in NFPA 211. The Chimney Liner & Rebuild in Yonkers service covers everything from a single flue liner replacement to taking the stack down to the roof line and building it back.
Most single-flue liner replacements are done in one day, including setup, site protection, installation, and the follow-up camera scan. A partial rebuild runs two to four days depending on weather and masonry curing time. A full rebuild from the roofline up is typically one to two weeks, with scaffold time, brick laying in lifts, crown pour, and flashing work, and we give you a written schedule with the written price before we start.
A stainless steel liner for a wood-burning fireplace in Yonkers typically costs $2,800 to $4,600, and furnace or boiler liners run $1,900 to $3,200. The spread depends on flue height, diameter, whether insulation wrap is required, and how many elbows or offsets the liner has to make. The written price you get from us names every part and the labor separately, so you can see exactly what you’re paying for before any work starts. Call (551) 212-3526 for a free written estimate.
Yes, we install and replace DuraFlex and Olympia Chimney liners regularly, and we keep their top plates, caps, and connectors in stock for faster scheduling. We also specify HeatShield for localized liner repair and Gelco caps and chase covers for rebuilds. If your existing liner is a brand we haven’t worked with, the camera scan tells us what’s actually in the flue, and we quote from there.
We answer live calls 24/7 at (551) 212-3526, and if the camera scan shows a flue that’s actively separated or a firebox with open gaps to framing, we’ll prioritize the job and get a written scope to you the same day. A liner or rebuild itself is scheduled, not rushed, because the work needs to cure and be documented, not just finished. If you have a chimney fire, call 911 first, then call us for the follow-up inspection.
Every liner and rebuild job is covered by the 365-Day Done Right Promise: if it’s not done right, we make it right at no charge within a year of the work. The materials themselves carry manufacturer warranties: stainless liners typically get a lifetime manufacturer warranty, and HeatShield work has its own covered period we include in your written proposal. Your written warranty is part of the written scope you sign before work begins, never an afterthought.
Clear the area around the fireplace or boiler by a few feet so we can lay drop cloths and set up the camera equipment, and move anything breakable off the mantel if we’re working on an open fireplace. Outside, make sure the chimney side of the house is accessible: unlocked gates, no parked cars directly under the scaffolding zone. We handle everything else, including permits where Yonkers requires them and full cleanup when the job is done.
