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.
Fast, Reliable Chimney Liner & Rebuild Across Sunset Park

Why Top Hat Chimney Is Sunset Park’s Preferred Chimney Liner & Rebuild Company
Wendell Pike founded Top Hat Chimney in 1999, and he still answers the phone. That matters in Sunset Park, where a lot of the work we do involves telling a landlord or homeowner the truth about a flue that’s been ignored for decades. We’re not a franchise that rotated in last spring. We’re a locally owned, owner-operated shop with a published address and license number, and Wendell puts his name on every job. Ask anyone on your street.
Sunset Park customers consistently tell us the same thing: they got burned by a national chain that quoted one price on the phone and a different one at the door. Our pricing works the opposite way. The number you hear on the phone is the number on the invoice. Every technician who shows up is background-checked, uniformed, and gets a real arrival window. If that window slips, we call you. Wendell and his crew work the same neighborhoods week after week, which means you’ll likely run into him again on Saturday.
Our Chimney Liner & Rebuild Services in Sunset Park
We handle the full range of Chimney Liner & Rebuild work, but in Sunset Park three services dominate the call volume: stainless steel liners, full rebuilds, and liner repair. Here’s what each one actually involves for the homes you’ll find along 4th, 5th, 6th, and 7th Avenues.
Stainless Steel Liner
For Sunset Park’s converted multi-family row houses, a 316L stainless steel liner is almost always the right call when the original terra-cotta flue has failed. These liners handle the condensation that gas boilers and water heaters produce far better than clay ever did. We size the liner to the combined BTU load of every appliance venting into that stack, and we show you the camera footage of the old flue before we quote a single dollar. A typical stainless liner install in Sunset Park runs $2,800-$5,200 depending on height and access.

Flexible Liner
Many Sunset Park chimneys have offset flue tiles, which makes rigid liners difficult or impossible to install. A flexible liner can snake through those offsets without tearing open the chimney. It’s a common solution for 1920s row houses on the side streets off 5th Avenue where the original masonry has shifted over a century of settling. Flexible liner work generally falls in the same $2,800-$5,200 range as rigid, though unusually tight offsets can add to the labor.

Liner Replacement
If your Sunset Park building still has its original unlined or terra-cotta flue and you’ve switched from oil or coal to gas, the liner is probably already failing. We see it constantly: crumbling clay tiles, gaps at the joints, and condensation eating the mortar from the inside. Liner replacement costs $2,800-$5,200 in most Sunset Park homes. You get the camera footage and a plain-English verdict, every time, no exceptions.

Partial Rebuild
A partial rebuild typically means reconstructing the chimney from the roofline up: crown, top courses of brick, and sometimes the first few feet of the stack. On Sunset Park’s harbor-facing slope between 4th Avenue and the water, salt-laden southwest winds off Upper Bay accelerate mortar erosion. That means crowns and top courses fail faster here than in inland Brooklyn neighborhoods at the same latitude. Expect $1,800-$4,000 for a partial rebuild, with scaffolding extra if roof access is tight.

Common Chimney Liner & Rebuild Problems We See in Sunset Park Homes
- Coal-era flues venting gas appliances. Sunset Park’s rows of 1890s-1925 attached brick homes were built with multi-flue chimney stacks sized for coal fireplaces. Most now vent gas boilers and water heaters through oversized, unlined, or crumbling terra-cotta flues. This coal-to-gas mismatch creates chronic condensation and liner deterioration block after block.
- Shared stacks serving multiple rental units. Along the dense rental corridors of 4th and 5th Avenues, a single deteriorated chimney stack commonly serves 3-4 converted apartments simultaneously. NYC DOB boiler registration requirements mandate periodic flue inspections tied to boiler permits, so landlords juggling multiple tenants on one stack face real compliance liability, not just a seasonal cleaning question.
- Salt-driven crown spalling on the west slope. Sunset Park sits on a glacial ridge directly above New York Harbor. Persistent southwest winds carry salt-laden moisture off Upper Bay, which accelerates spalling and mortar erosion on chimney crowns and top courses noticeably faster than inland Brooklyn. A crown that looks fine from the street can be structurally gone once you’re up there.
- Deferred maintenance from rental turnover. In a neighborhood where many buildings are 2-4 unit rentals, liner and crown work often gets pushed off until a boiler permit inspection forces the issue. By then, tenants in converted units may have been living with backdrafting risk for months. A camera inspection takes less than an hour and ends the guessing.
Pricing for Chimney Liner & Rebuild in Sunset Park, NY
Here are the numbers we typically quote in Sunset Park, based on the housing stock and roof access conditions we see every week:
| Service | Typical Sunset Park Range |
|---|---|
| Stainless steel liner (installed) | $2,800-$5,200 |
| Flexible liner (installed) | $2,800-$5,200 |
| Liner repair (joint sealing, minor) | $600-$1,400 |
| Partial rebuild (crown + top courses) | $1,800-$4,000 |
| Full chimney rebuild (roofline up) | $5,500-$12,000 |
What actually moves the number inside these ranges? Roof access is the big one. A steep-pitched roof on a 54th Street row house with no rear yard means scaffolding, and scaffolding costs real money. Height matters too: a four-story stack costs more to work on than a two-story one. When you call us, you’ll get upfront pricing before a single tool comes off the truck. We also offer $40 off any repair over $200, a free second opinion on any competing written estimate, and 10% off always for seniors and veterans. Ask for details when you call (516) 289-9316.

FAQs - Chimney Liner & Rebuild in Sunset Park
No, you don’t need separate liners. A single properly sized stainless steel liner can handle multiple gas appliances, provided the liner diameter matches the combined BTU load of everything venting into that stack. What matters is that the liner is sized correctly and installed with proper termination at the top. In Sunset Park’s converted multi-family row houses, we regularly see one shared stack serving three or four apartments, and the fix is usually a single 316L liner sized for the total load, not three separate ones. Call (516) 289-9316 and we’ll walk you through what your specific setup requires.
On 54th Street between 4th and 5th Avenues, we found a three-family brick row house with one shared stack venting three gas boilers through a collapsed terra-cotta flue. The liner had offset at the second-floor level, so we installed a 316L stainless steel liner sized for the combined BTU load and rebuilt the chimney crown with a proper cast-in-place wash to stop the salt-driven spalling from the harbor winds. One liner, one crown, three apartments served safely.
You’ll typically see water stains on ceilings or walls adjacent to the chimney chase, peeling paint, or efflorescence on interior brick. On Sunset Park’s west slope, salt-driven spalling eats crowns faster than most people expect, so a crown that looked serviceable five years ago may be letting water in today. The only way to know for certain is a camera inspection from the top down and the bottom up. We’ll show you the footage and give you a plain-English verdict, every time, no exceptions. Call (516) 289-9316 for a free estimate.
Yes, in most cases. Flexible liners are designed specifically to navigate offsets and irregularities in older flues, which is why they’re common on Sunset Park’s 1920s row houses where a century of settling has shifted the original terra-cotta tiles. There are limits: severe collapses or extreme angles may require partial demolition or a rigid liner instead. We’ll tell you which one your chimney actually needs after the camera shows us what’s in there. Reach us at (516) 289-9316 to schedule an inspection.
It can be. Occasional CO detector alarms in a converted Sunset Park rental often trace back to backdrafting caused by a deteriorated or collapsed flue liner, especially where a single stack serves multiple units and appliances. Carbon monoxide is odorless and the risk is real. If your detector is going off, don’t wait for the landlord or the next boiler permit inspection. Call (516) 289-9316 and we’ll help you figure out the next step, including whether a camera inspection is warranted now. Your flue doesn’t care how the fire looks. It cares how it breathes.
Because Sunset Park sits on a glacial ridge directly above New York Harbor, and the harbor-facing side absorbs persistent southwest winds carrying salt-laden moisture off Upper Bay. That combination attacks chimney crowns and mortar joints far more aggressively than inland Brooklyn neighborhoods at the same latitude. The fix isn’t just repointing; it’s usually a proper cast-in-place crown and possibly replacement of the top courses of brick. We see this pattern on 4th and 5th Avenue buildings repeatedly. Call (516) 289-9316 and we’ll give you an honest read on what your stack actually needs.
