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.

AfterHow Much Does Chimney Liner & Rebuild Cost in Long Island?
Chimney liner installation in Long Island typically runs $2,500 to $7,000, depending on flue length, liner material, and whether the masonry above the firebox needs partial or full rebuilding. Our Chimney Liner & Rebuild services cover everything from the firebox up through the crown, with full rebuilds landing between $4,500 and $12,000 for most Long Island homes. We give you the exact number before a single tool comes off the truck, so there are no surprises on invoice day.
If you want a quick read on what’s involved in the work itself before you dig into pricing, our Chimney Liner & Rebuild in Long Island service page lays out the process from inspection to finished flue.
Chimney Liner & Rebuild Cost Breakdown (2026)
Long Island’s housing stock skews older - a lot of Cape Cods and colonials in Levittown, Massapequa, and Farmingdale that were built in the late 1940s and 1950s with single-wythe terra cotta tile liners that are now 70-plus years old. Replacement costs here reflect that reality: longer flues, tighter chases, and stricter Suffolk and Nassau County permit requirements all factor into the final number. Here’s how the line items stack up in this market right now.
| Service | Typical Range (Long Island, 2026) |
|---|---|
| Stainless steel flexible liner (gas appliance, per flue) | $1,800 – $3,200 |
| Stainless steel flexible liner (wood-burning, per flue) | $2,500 – $4,500 |
| HeatShield flue resurfacing (cast-in-place system) | $2,800 – $6,500 |
| DuraFlex liner system (all-fuel rated) | $2,900 – $5,200 |
| Partial chimney rebuild (firebox to roofline) | $3,500 – $6,500 |
| Full chimney rebuild (firebox through crown) | $4,500 – $12,000 |
| Firebox rebuild only | $1,200 – $3,800 |
| Crown replacement (as part of liner project) | $350 – $850 |
| Liner plus chimney cap (Gelco or Olympia Chimney) | Add $180 – $420 |
| Permit filing (Nassau or Suffolk County) | $150 – $400 (varies by municipality) |
Those ranges are real Long Island numbers, not national averages ported in from a content farm. Labor rates on Long Island run higher than upstate or out-of-state benchmarks - figure roughly 40 to 60 percent of your total bill is labor when a full liner installation is involved. Materials make up the rest, and that split shifts toward materials when you’re going with a premium cast-in-place system like HeatShield or a heavy-gauge DuraFlex all-fuel liner rated for wood, oil, and gas.
A few things pull the number toward the top of the range fast: two-story colonials with 30-foot flues, offset chimneys with more than one bend (common in older ranch-style homes in Wantagh and Seaford), and any rebuild that requires scaffolding above the roofline. A single-story Cape with a straight, accessible flue sits closer to the floor of those ranges.
What Affects Chimney Liner & Rebuild Pricing in Long Island
- Flue height and diameter. Most Long Island homes have flues between 20 and 35 feet. Every additional foot of liner material adds cost, and wider flues (8-inch versus 6-inch, for example) require heavier-gauge stainless that costs more per linear foot. A two-chimney Colonial in Syosset or Huntington with separate flues for the fireplace and the furnace means two separate liner runs - plan for it.
- Number of offsets. A straight shot from firebox to cap is the easiest and cheapest install. Some Long Island homes, particularly older ones in Merrick and Baldwin that were retrofitted with gas inserts, have one or two bends built into the chase. Each offset requires a flexible liner system rather than a rigid one, and the extra fittings and labor add $300 to $700 per bend in this market.
- Liner material and fuel type. Gas appliances can use a lighter-gauge single-wall liner; wood-burning fireplaces require a heavier double-wall or all-fuel-rated liner. If you switch from gas to wood - or add a pellet stove insert - the liner spec changes entirely. We see this often in Smithtown and Commack where homeowners are adding wood stoves and finding the existing liner isn’t rated for solid fuel.
- Extent of masonry damage. A liner job that uncovers spalled brick, deteriorated mortar joints, or a cracked smoke chamber becomes a liner-plus-rebuild job. On Long Island’s coast - think Freeport, Bellmore, Wantagh - salt air accelerates mortar erosion faster than it would ten miles inland. A video inspection before the quote catches this early and keeps the estimate honest.
- Permit requirements. Nassau and Suffolk Counties both require permits for liner installations and structural chimney rebuilds. The filing fee alone ranges from $150 to $400 depending on the municipality, and some villages in the Five Towns area have additional inspection steps that add a week or two to the timeline. We handle permit filing - we’re not going to leave you to sort that out on your own.
- Access and scaffolding. A chimney that’s tall, steeply pitched, or positioned awkwardly over a flat roof requires scaffolding rather than ladder access. That adds a real cost - typically $400 to $900 for a residential setup on Long Island. It’s a safety requirement, not a upsell, and any contractor skipping it on a tall chimney should raise a flag for you.
How to Save on Chimney Liner & Rebuild
The biggest savings on a liner or rebuild job come from catching problems early, not from shopping for the lowest-bid contractor. A deteriorating liner that gets addressed in year one of showing wear costs a fraction of what the same flue costs to replace after a chimney fire or carbon monoxide event. That’s not a scare tactic - it’s the straightforward math of repair-versus-replacement that Wendell has run through with Long Island homeowners since 1999.
That said, here’s where legitimate savings exist without cutting corners:
- Bundle the liner with a chimney sweep and inspection. If the sweep is already on site, the video inspection and pre-liner assessment usually costs nothing extra. You’re paying for one trip, not two. We do this routinely on Long Island - the sweep happens first, the camera goes up, and you get a full condition report before anyone talks liner pricing.
- Get the work done in late summer or early fall. September and early October are our busiest weeks on Long Island because everyone realizes winter is six weeks out. Scheduling in July or August - when sweeps have more flexibility - sometimes means a faster appointment and, on bundled jobs, a better overall price.
- Ask about combining a liner job with crown or cap work. If the crown is cracked and the cap is corroded, doing both at the same mobilization as the liner saves a return trip. One truck, one job, one permit cycle where applicable.
- Take the $40 off any repair over $200. If your liner job includes any repair component - and most do - that standing discount applies. Seniors and veterans get 10% off always, no paperwork required.
- Get a free second opinion on any written estimate. If a national chain handed you a quote that felt high or vague, bring the paper. We’ll tell you what the number should look like for your specific chimney, on Long Island, in 2026. That opinion is free, no strings attached.
- Verify what the quote actually includes. Some contractors quote liner-only and add cap, permit, and disposal separately. Ask for an itemized, written quote before you agree to anything. Ours is always itemized, upfront, and the number you hear is the number on the invoice.

FAQs – Chimney Liner & Rebuild Cost
How much does chimney liner installation cost in Long Island in 2026?
A stainless steel liner installation in Long Island costs $1,800 to $4,500 for most residential flues, with the lower end covering gas appliances on shorter, straight flues and the upper end covering wood-burning systems with offsets or longer runs. HeatShield cast-in-place resurfacing runs $2,800 to $6,500 for the same reason: it’s a more labor-intensive process and takes longer to cure. Both numbers include labor and materials but not permit fees, which vary by municipality in Nassau and Suffolk. Call (516) 968-5380 for an exact quote – estimates are free.
How much does a full chimney rebuild cost on Long Island?
A full chimney rebuild on Long Island – from the firebox up through the crown – typically runs $4,500 to $12,000. The range is wide because rebuild scope varies enormously: a two-story home in Huntington with a 35-foot masonry chimney that needs scaffolding is a very different job from a single-story ranch in Wantagh where the damage is confined to the top two feet above the roofline. Partial rebuilds (roofline to crown only) run $3,500 to $6,500 for most Long Island homes. Call (516) 968-5380 for a written, itemized estimate – it’s free, and the number doesn’t change at the door.
Do I need a permit for chimney liner installation in Long Island?
Yes, in most Long Island municipalities you need a permit for a new liner installation or a structural chimney rebuild. Nassau and Suffolk County both require permits, and filing fees generally run $150 to $400 depending on the specific village or town. Some areas in the Five Towns and North Shore communities have additional inspection steps. We handle permit filing as part of the job – it’s not something we push back to you to figure out.
Is it cheaper to reline or rebuild a chimney?
Relining is almost always cheaper than rebuilding, assuming the masonry structure is still sound. A liner installation runs $1,800 to $4,500 for most Long Island flues; a full rebuild starts at $4,500 and can reach $12,000 for larger chimneys. The question becomes rebuild-versus-reline only when a video inspection shows structural deterioration in the brick or mortar that relining alone can’t fix. We run a camera every time before quoting so you know exactly which category your chimney falls into – and we’ll tell you honestly if a reline is all you actually need. Call (516) 968-5380 to get that inspection on the schedule.
How long does a chimney liner or rebuild take in Long Island?
A standard liner installation – straight flue, single appliance, no significant masonry work – takes one day for most Long Island homes. A liner with partial masonry repairs typically runs one to two days. A full chimney rebuild can take two to four days depending on chimney height, scaffold setup, and permit inspection timing. If your municipality requires a mid-work inspection (some North Shore villages do), that can add a few days of waiting even after the physical work is done. We’ll walk you through the realistic timeline before we start, not after.
Does Top Hat Chimney offer any discounts on liner or rebuild jobs?
Yes. We take $40 off any repair over $200, which applies to most liner and rebuild jobs that include repair work – and most do. Seniors and veterans get 10% off, always, no special request needed. We also offer a free second opinion on any written estimate you’ve received from another contractor. There’s no trip charge for jobs inside our home service county. Call (516) 968-5380 and ask – the person who picks up will go through all of it with you.
Who Should You Trust with a Liner or Rebuild Job on Long Island?
This matters more than most homeowners realize when they’re getting quotes. A chimney liner is a life-safety component. A bad liner installation – undersized, wrong material for the fuel type, improperly sealed at the appliance connection – can cause carbon monoxide to back-draft into a living space or allow flue gases to contact combustible framing. High-tension liner installation also carries real physical risk, which is why trained sweeps and masons handle the work rather than homeowners doing it themselves. This is one job where “close enough” isn’t an option.
Wendell Pike has been doing this work on Long Island since 1999. Not a franchise, not a rotating crew of strangers, not a call center that books the job and sends whoever is available. Top Hat Chimney is locally owned and owner-operated, which means Wendell runs into the same homeowners at the hardware store on Saturday morning that he worked for on Thursday. That’s a different kind of accountability than a national outfit with a 1-800 number provides.
Every job comes with the 90-Day Done Right Promise in writing: if something isn’t right after we leave, one call brings us back at no additional cost. That’s not a marketing phrase – it’s a written commitment stamped on every single job, and it’s been that way since 1999. We work with liner systems and materials we trust: DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. Those are names the industry respects for a reason, and they’re what goes into your flue when we do the job.
If you’ve already had a quote that felt vague, or a price that changed when the truck showed up, bring that written estimate to us. The second opinion is free. We’ll read it, tell you what it should say, and give you a number for your specific chimney – not a national average, not a range so wide it’s useless. A real price for a real flue in Long Island.
