Chimney Liner & Rebuild Cost - Camera Evidence Before Any Quote

Every visit starts with

Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed

Worth knowing

Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

How Much Does Chimney Liner & Rebuild Cost in Yonkers?

Chimney liner installation in Yonkers, NY typically costs $1,800 to $5,500, depending on liner type, flue height, and the condition of your existing masonry. A full chimney rebuild – our Chimney Liner & Rebuild services cover new liner, smoke chamber, crown, and repointing – runs $6,500 to $18,000 for most Yonkers homes. Level Two Chimney Co. puts the price in writing before any work starts, on every job, no exceptions.

Chimney Liner & Rebuild Cost Breakdown (2026)

The table below reflects what homeowners in Yonkers are actually paying in 2026 – not a national average copied from a content farm. Prices are based on work completed in Westchester County, covering neighborhoods from Park Hill to Nodine Hill to Crestwood. Your flue height, liner diameter, and chase condition will move your number within these ranges.

What pushes the price up

Most price surprises in Yonkers come from one of three things: flue height, access, and what the camera finds inside. Older homes in Getty Square or the Hollow neighborhoods tend to have taller chimneys than newer construction further east near Scarsdale Road – every additional foot of liner adds material and labor cost. If your roofline is steep or the chimney sits at an awkward peak, rigging takes longer. And if a camera scan reveals a collapsed tile section or active moisture damage deep in the flue, that’s a different job than a clean liner drop.

Permits are worth mentioning here. New York State requires that liner installations on fuel-burning appliances meet NFPA 211 standards, and the City of Yonkers Building Department may require a mechanical permit depending on scope – specifically when work is connected to a gas appliance or a wood-burning insert. We handle permit navigation as part of every quoted job. If a competitor’s estimate doesn’t mention permitting, ask them about it before signing anything.

What Affects Chimney Liner & Rebuild Pricing in Yonkers

• Liner type and material: Flexible stainless steel liners (DuraFlex is our primary source) are the most common choice for gas and oil-burning appliances. Cast-in-place poured liners cost more but are the right call for irregular or oval-shaped flues, which show up often in Yonkers homes built before 1940. HeatShield resurfacing sits in the middle – it’s not a full liner, but it can restore a structurally sound flue to code compliance at lower cost.
• Flue diameter and height: A standard 6-inch single-flue liner on a two-story Yonkers colonial runs about 25 to 30 feet of material. An 8-inch liner for a larger wood-burning system on a three-story home near North Broadway can be 40 feet or more. Material cost alone scales with those numbers.
• Pre-existing damage found during camera scan: We run a Level 2 inspection camera down every flue before quoting liner work. In Yonkers, we regularly find mid-flue tile collapses in homes where the original clay liner hasn’t been serviced in 15-plus years. A collapse changes the liner installation from a straightforward drop to a partial demolition-and-rebuild scenario – and that’s priced differently. You want to know that before the job starts, not after.
• Chimney height and roof access: The older neighborhoods in southwest Yonkers – Nodine Hill, the Hollow, Ashburton – have some of the tallest chimney stacks we work on in Westchester County. Extra height means more liner material, more anchor points, and in some cases, scaffolding rather than ladder access. Scaffolding alone can add $400 to $900 to a job.
• Scope of rebuild work: A liner replacement on a chimney with solid masonry is one job. That same chimney with spalling brick, a crumbling crown, and a deteriorated mortar bed is a different job. We see a lot of the latter in Yonkers: the freeze-thaw cycle in this part of Westchester is aggressive, and chimneys that were last repointed 20 or 30 years ago often need crown work and repointing done at the same time as the liner. Bundling that work into one visit typically costs less than scheduling it separately.
• Number of flues: Some Yonkers homes – particularly larger colonials and Tudors in the Park Hill and Crestwood areas – have two or three separate flues serving different appliances. Each flue is a separate liner. A two-flue job is not double the price of one, but it’s not far off for materials.

How to Save on Chimney Liner & Rebuild in Yonkers

Get the inspection camera result before you commit to anything

The single biggest mistake Yonkers homeowners make is agreeing to a liner or rebuild scope based on a visual inspection from the firebox opening or the roof. A flashlight look tells you almost nothing about what’s happening in the middle 20 feet of your flue. At Level Two, the NFPA 211 Level 2 camera scan is standard on every visit – included, not an add-on. The camera footage and photo record are what the written price is based on. You’re not buying a guess; you’re buying a quote tied to documented findings.

If you’ve already got a written estimate from another company, bring it to us. Our Free Second Opinion offer is straightforward: we’ll send a tech, run the camera, and give you a written comparison. No charge. If their price is better and the scope is equivalent, say so – we’ll tell you honestly whether it’s apples to apples.

Don’t stage work unnecessarily

If your chimney needs both a new liner and crown replacement, doing those in the same visit is almost always cheaper than two separate trips. Mobilization – getting the tech, the materials, and the access equipment to your Yonkers address – is part of every job’s cost. One trip, two tasks, lower total bill. We’ll tell you upfront which items make sense to combine and which don’t.

Ask about HeatShield before defaulting to a full liner

Not every Yonkers flue needs a full liner replacement. If the tile liner is structurally intact but shows hairline cracks and surface spalling – which is common in flues on gas appliances that haven’t been serviced in years – HeatShield resurfacing can restore the flue to NFPA 211 compliance at $1,200 to $2,400 less than a full liner install. The camera scan will tell us which category your flue falls into. We’re not going to recommend a liner if resurfacing is the right call.

Schedule before peak season

Late September through early December is the busiest period for chimney work in Yonkers, when homeowners light their first fire and realize something’s wrong. If you’re reading this in spring or summer and you know your chimney needs attention, scheduling now means faster availability and, in some cases, better material lead times on specialty liner sizes. We don’t run seasonal promotions or pressure pricing – the written estimate reflects current material costs whenever you call. But availability is genuinely better off-peak.

Verify the scope covers permits and cleanup

Some Yonkers contractors quote the liner and leave out the permit application, disposal fees, and post-job cleanup. Those aren’t optional. Ask before you sign anything: does this price include permit filing, flue debris removal, and a photo record on completion? At Level Two, the answer is yes, and it’s in the written scope before work starts – Haven Standard Clause 1 requires it.

FAQs – Chimney Liner & Rebuild Cost in Yonkers

How much does chimney liner installation cost in Yonkers, NY?

Chimney liner installation in Yonkers costs $1,800 to $5,500 for most homes, depending on liner type (flexible stainless, cast-in-place, or HeatShield resurfacing), flue diameter, and height. A flexible stainless liner for a gas appliance on a two-story home – the most common job we do in Yonkers – typically comes in at $2,000 to $2,800. A wood-burning liner on a taller stack runs closer to $3,200 to $3,800. The number on your written estimate will be based on camera footage, not a visual guess. Call (551) 212-3526 for a free, written estimate.

How much does a full chimney rebuild cost in Yonkers?

A full chimney rebuild in Yonkers – from the firebox or foundation up through the cap – costs $10,000 to $18,000 depending on height, masonry condition, and whether the smoke chamber and liner are included in the scope. A partial rebuild limited to the section above the roofline (the most common scenario in Yonkers, where freeze-thaw spalling damages the top several feet) runs $3,500 to $8,000. We’ll camera-document what we find and give you a line-item written price before any work starts. Call (551) 212-3526 for a free estimate.

Is it cheaper to reline or rebuild a chimney in Yonkers?

Relining is almost always less expensive than rebuilding – $1,800 to $5,500 for a liner versus $6,500 to $18,000 for a rebuild. The right answer depends on the masonry. If the brick structure and mortar are sound and only the flue liner is damaged, relining is the correct call. If the masonry itself is cracked, shifted, or structurally compromised – something we see on older stacks in southwest Yonkers that have gone decades without maintenance – then rebuilding the affected sections is unavoidable. The camera scan and a written scope will tell you exactly which category you’re in. Call (551) 212-3526 – estimates are free and in writing.

Does Yonkers require a permit for chimney liner installation?

Yes, in many cases. New York State requires liner installations on fuel-burning appliances to meet NFPA 211 standards, and the City of Yonkers Building Department typically requires a mechanical permit when liner work is connected to a gas appliance, oil burner, or wood-burning insert. The permit requirement depends on scope and appliance type. Level Two handles permit navigation as part of every quoted job – if a permit is required for your work, it’s included in the written scope before we start. If your current estimate from another company doesn’t address permitting, that’s a question worth asking before you sign.

How long does chimney liner installation take in Yonkers?

Most liner installations in Yonkers take 4 to 8 hours in a single visit. A straightforward flexible stainless liner drop on a standard two-story home is typically on the shorter end – 4 to 5 hours including the Level 2 camera inspection before and the photo documentation after. A cast-in-place poured liner or a liner paired with smoke chamber parging and crown work can run a full day. We’ll tell you the expected time window in the written scope so you’re not guessing. For a same-week appointment, call (551) 212-3526.

Why Yonkers Chimneys Wear Out Faster Than You’d Expect

Yonkers sits at the lower edge of Westchester County, close enough to the Hudson that winter moisture gets into mortar joints harder than it does further inland. The freeze-thaw cycle here – temperatures that drop below freezing at night and climb above it during the day, sometimes multiple times in a single week between November and March – is genuinely aggressive on masonry. Water works into the smallest mortar gap, freezes, expands, and widens the crack. Repeat that 40 or 50 times in a winter and you understand why chimneys in Park Hill, Nodine Hill, and the Hollow often need partial rebuilds by the time they’re 30 to 40 years old, even if they were well-built originally.

The flue liner takes a different kind of abuse. Clay tile liners – standard in Yonkers homes built before the mid-1980s – are not designed to handle the thermal cycling and condensate produced by modern high-efficiency gas appliances. Those appliances burn so efficiently that their exhaust gases are cool enough to condense inside the flue before they exit, producing acidic moisture that degrades tile liner joints over time. We’ve run the camera down flues in Crestwood and Dunwoodie that looked fine from the firebox opening but had mid-flue tile joint separations and partial collapses that made the system non-compliant and, frankly, unsafe to operate. The camera finds what a flashlight inspection won’t.

Since 2009, Level Two Chimney Co. has completed more than 38,000 chimney inspections and cleanings in the New York metro area, every one with a written price before work started and a documented photo record on completion. Corrine Halstead leads our Yonkers operation, and that consistency – camera down the flue, written price, documented record – is what Haven Standard Clause 4 codified years before it became standard industry practice.

What You Get From Level Two on Every Liner or Rebuild Job

Before we quote anything, we run a Chimney Liner & Rebuild in Yonkers assessment using the NFPA 211 Level 2 camera. You see what we see. The written price is tied to those findings, not to a general scope that gets revised once the job starts.

• Written price before work starts – always, on every job, no exceptions. This is Haven Standard Clause 1 (H.A.V.E.N.: “Have it in writing”).
• Documented photo record on completion – Haven Standard Clause 4, included as standard. Not an optional add-on.
• Written scope and written warranty – delivered before anyone touches your chimney.
• 365-Day Done Right Promise – if it’s not right, we make it right. Stamped on every job.
• Background-checked, uniformed technicians – a named tech assigned to your job, with a text when they’re on the way.
• Free Second Opinion on any written estimate from a competitor – bring us the paper, we’ll run the camera and compare.
• Materials sourced from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield – procured through Haven’s buying network to keep material costs honest.
• Live phone support, 24/7 – a real person answers at (551) 212-3526, not a voicemail.

We’re not the company that shows up with a flashlight and calls it an inspection. The camera has been standard since 2009 because it’s the only way to give you a price that reflects what your flue actually needs – not what it looks like it needs from the firebox.
