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 New York City Homeowners
A chimney liner replacement or partial rebuild in New York City typically runs $3,800 to $9,500 depending on the flue size, liner material, and how much of the crown or brickwork has failed - similar to our Chimney Liner & Rebuild in Los Angeles pricing structure. Most liner jobs in the five boroughs take one full day, though a full chimney rebuild from the roofline up can run three to four days. We’ve inspected over 38,000 chimneys since 2009, every one with a written price before work started. If you’re seeing flue tile fragments in the firebox, white staining on the exterior brick, or your carbon monoxide detector keeps reading low but present, call (980) 580-8641 and we’ll bring a camera up the flue.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is a continuous metal flue installed inside the existing chimney to contain heat and combustion byproducts. You need one when the original clay tile liner has cracked, spalled, or separated at the mortar joints, which is common in New York City’s prewar and mid-century housing stock. We size the liner to the appliance and flue dimensions, install it with a proper top plate and rain cap, and document the full run with camera footage before and after. We stock DuraFlex and Copperfield liner systems because their wall thicknesses and alloy grades hold up to the thermal cycling a New York chimney sees between a January cold snap and a July heat wave.
Flexible Liner
A flexible liner is a single continuous corrugated steel tube used when the flue has offsets or bends that a rigid liner can’t navigate. It’s common in older New York City row houses and converted brownstones where the original flue was routed around structural beams. The tradeoff is real: flexible liners can trap slightly more creosote in their corrugations, so the sweep interval matters. We recommend flexible only when the flue absolutely requires it, and we note the sweep cadence in writing so there’s never a guess about maintenance.
Liner Replacement
Liner replacement means removing the old, failed liner and installing a new one, whether that’s a stainless steel tube, a poured cast-in-place liner, or a HeatShield cerfractory coating. In New York City we frequently find clay tile liners from the 1920s through 1960s that have horizontal cracks at every third joint, usually from decades of hot fires followed by cold air. The written quote spells out exactly what comes out and what goes in, including the liner diameter, gauge, and termination cap model. That specificity is Clause 1 of the Haven Standard: a written scope before anyone starts work.
Partial Rebuild
A Chimney Liner & Rebuild in Huntington Park style partial rebuild addresses the top section of the chimney, typically from the roof line up: the crown, the top three to five courses of brick, and the flue tile that sits above the roofline. In Queens and Brooklyn, we regularly rebuild crowns that were poured with plain concrete instead of a proper overhanging crown with a drip edge, which is why water has been getting behind the brick face. A partial rebuild in New York City often costs between $2,200 and $4,800, and we provide a documented photo record of every course as it goes back in. Corrine Halstead, who leads our crew, will walk you through the photos on site.
Full Chimney Rebuild
A Chimney Liner & Rebuild - South Gate type full chimney rebuild is what it sounds like: taking the structure down to the roofline or further and rebuilding it with new brick, new mortar, a new liner, and a new crown. This is the right call when the brick has lost its structural integrity, often visible as spalling, bulging, or a visible lean from the street. In New York City, full rebuilds are most common on exposed exterior chimneys in The Bronx and Staten Island where wind-driven rain and freeze-thaw cycles have worked on the mortar for decades. We do the structural assessment first, with photos of the brick face, the mortar bed, and the interior flue, and only then does a rebuild quote come together.
Liner Repair
Liner repair covers targeted fixes rather than full replacement: patching a cracked tile joint, sealing a gap at the smoke chamber, or resurfacing the flue walls with a ceramic coating. It’s a legitimate option when the liner is mostly intact and the failure is localized, though it’s not a fix for a liner with multiple vertical cracks. We’ll tell you plainly when a repair will hold and when it won’t, because the camera footage doesn’t lie. If a repair is recommended, you’ll see the before and after images and get the product data sheet for the material we used.

Brands We Service for Chimney Liner & Rebuild
We work extensively with DuraFlex products, specifically their 316L and 316Ti alloy liner systems. DuraFlex is a common spec in New York City because the alloy holds up to the acidic condensate produced by modern high-efficiency gas appliances, which can eat through a standard aluminum liner in a few seasons. We’ve installed and serviced hundreds of DuraFlex liners since 2009 and stock their termination caps, top plates, and connector hardware on our trucks.
Copperfield is the other liner system we regularly install, particularly for wood-burning fireplaces where the creosote and thermal load are heavier. Copperfield’s smooth-wall rigid sections are our default when the flue is straight enough to accept them. If your liner is Famco, HeatShield, or any other make, we service those too, and the inspection process is identical: camera up the flue, written report, written price. The brand of liner matters less than the condition of the installation, and that’s what we document.
BeforeAfterSigns You Need Chimney Liner & Rebuild Right Now
- Flue tile fragments in the firebox. You sweep the ash and find small, sharp pieces of terracotta that look like broken flower pot. That means the clay liner has cracked somewhere above the damper and pieces are falling back down. A cracked liner is an open channel for heat and combustion gases to reach the brickwork behind it.
- White staining (efflorescence) on the exterior brick. Efflorescence is the mineral salts left behind when water moves through masonry and evaporates. It tells you water is inside the brick, not on the outside. In New York City’s freeze-thaw winters, that trapped water expands, and the brick face spalls off in sheets over a few seasons.
- Low but consistent carbon monoxide readings. If a CO detector in the room near the fireplace reads consistently even at 5-10 ppm, the flue isn’t drafting properly. That’s often a cracked liner, a blocked flue, or a negative pressure issue in a tight New York apartment. It is not something to wait on. Call (980) 580-8641 and we’ll run a camera and a draft test.
- Visible cracks in the chimney crown or missing mortar joints. Stand across the street and look at the top of your chimney. If the concrete crown looks like a dry lake bed, water is getting behind the brick face. If you can see daylight through the mortar joints from an angle, the chimney has lost structural bonding.
- A smell you can’t place when the fireplace isn’t in use. A properly functioning chimney doesn’t smell like anything. A damp, sooty, or acrid smell that comes and goes with the weather usually means creosote or water is sitting somewhere in the flue, and the first thing to check is whether the liner is still intact.
Our Chimney Liner & Rebuild Process - Step by Step
- 1
Camera inspection of the entire flue. We run a Level 2 camera scan from the firebox to the termination cap, recording the full length. You watch the screen with us. We’re looking for cracks, separations, blockages, and the condition of the smoke chamber. This is what NFPA 211 calls for, and it’s been our standard practice since 2009, before most of the industry adopted it. Home page has more on how we work.
- 2
Written scope and written price, before any work starts. After the inspection, you get a document that names the liner material, the diameter, the length, the termination cap model, the crown specification, and the exact dollar figure. No verbal ballpark, no “we’ll see when we get up there.” Clause 1 of the Haven Standard: have it in writing.
- 3
Site protection and access setup. We lay drop cloths from the entry to the hearth, mask off the work area, and set up ladder points or roof anchors as needed. In New York City, roof access varies block by block: some brownstones have hatch access, some require a 40-foot extension ladder from the sidewalk. We’ve done all of it.
- 4
Liner installation or rebuild work. The old liner comes out where feasible, or we install the new liner alongside the existing passage as the flue dimensions allow. Brick work is re-pointed, the crown is poured with a 2-inch overhang and a drip edge, and the rain cap is installed and sealed. Photos at every stage.
- 5
Final camera pass and documented record. We run the camera a second time to verify the liner is seated, connected, and free of obstructions. You receive the photo record, the written scope, the written warranty, and the maintenance schedule. That documented archive is Clause 4 of the Haven Standard, the practice we started in 2009 and have kept on all 38,000+ jobs since.
How Much Does Chimney Liner & Rebuild Cost in New York City?
A stainless steel liner replacement in New York City typically runs $3,800 to $6,500 for a single-story flue, and $5,500 to $9,500 when scaffolding or a multi-story roof access is required. A partial rebuild, crown and top courses, adds $2,200 to $4,800 on average. A full chimney rebuild from the roofline up runs $8,000 to $18,000 or more depending on brick availability and access. These are real numbers for this market, not national averages with the edges shaved off.
What moves the price: roof access (walk-up brownstone vs. mid-rise), whether the existing liner can be removed or must be left in place, the flue diameter, and whether the crown is being replaced at the same time. The way to avoid overpaying is to get the scope in writing before you sign anything. We do that on every job, no exceptions. And if you have a written estimate from another company, we’ll give you a free second opinion on it. The estimate we write is the price you pay, with the warranty named before work begins.

Frequently Asked Questions - Chimney Liner & Rebuild in New York City
A chimney liner is the flue passage inside the chimney that contains heat, smoke, and combustion gases. Rebuild work - like a Chimney Liner & Rebuild in Bell - is the masonry repair or reconstruction of the chimney structure itself: the crown, the brick courses, or the full stack from the roofline up. At Emberly Chimney Cleaners, we inspect, replace, and rebuild both, documenting every step with camera footage and a written scope.
A standard stainless steel liner installation takes one day from setup to final camera pass. A partial rebuild takes one to two days depending on how many brick courses are involved and whether custom brick matching is needed. A full chimney rebuild takes three to four days, plus a day for the mortar to cure before the cap is sealed.
A liner replacement in New York City typically costs $3,800 to $9,500 when you factor in the liner, the termination cap, the crown work if needed, and the access. The exact number depends on the flue length, the liner diameter, and whether your roof access requires laddering or scaffolding. Your written quote from us names every line item before work starts. Call (980) 580-8641 for an exact quote, free of charge.
Yes. We install and service both DuraFlex and Copperfield liner systems, and we keep their termination caps and connector hardware stocked on our trucks. If your existing liner is a different brand like Famco or HeatShield, we inspect and repair those as well. The inspection process is the same regardless of brand: camera up the flue, written photos, written price.
A cracked liner is a safety issue, not necessarily a 911 emergency, but the risk scales with use. If you’re burning wood or running a gas appliance through a compromised flue, heat and carbon monoxide can reach the structure behind the liner. If you have a low CO reading or visible tile fragments in the firebox, call (980) 580-8641 and we’ll schedule an inspection as soon as we can get a crew to your borough.
Every job includes the 365-Day Done Right Promise: if the work isn’t done right, we make it right within one year of completion. The specific liner manufacturer warranty is named in the written scope before work starts, because it varies by product line and alloy grade. We don’t hide warranty terms behind a phone call; they’re in the contract you sign.
Clear the area around the fireplace about six feet back, remove decorations from the mantel, and make sure there’s a clear path from the entry to the hearth. If roof access will be through an interior hatch or bulkhead, have that path clear too. We’ll text you when the crew is on the way, and every technician arrives in uniform with a visible license number.
