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.

AfterFast, Reliable Chimney Liner & Rebuild Across Elmhurst
A chimney liner replacement or rebuild in Elmhurst typically runs $1,800 to $6,500 depending on whether we’re relining a single flue or rebuilding a shared party-wall chimney crown-to-wash. Most jobs on the attached brick rowhouses that define this neighborhood take one to three days once we’re on the roof. If you’ve been told you need a liner before a boiler permit will go through, or you’ve seen black streaking inside your flue, call (929) 822-6306 and Wendell or one of the crew will walk you through exactly what’s involved, with upfront pricing before a single tool comes off the truck.
We work Elmhurst every week, and we know this housing stock. That matters more here than almost anywhere else in Queens, because these are not standalone homes. They’re attached. They share walls, they share parapets, and far too many of them share flues that were never meant to carry a modern gas appliance.
Why Top Hat Chimney Is Elmhurst’s Preferred Chimney Liner & Rebuild Company
Top Hat Chimney has been owner-operated since 1999. Wendell Pike puts his name on every job, publishes his license number, and backs the work with a 90-Day Done Right Promise in writing. If it’s not right, one call brings the crew back at no additional cost. That’s the kind of accountability that matters when you’re about to spend several thousand dollars on a liner and rebuild, and it’s why homeowners in Elmhurst keep our number.
We answer the phone with a live person, around the clock. Not a call center. Often it’s Wendell himself. When you schedule a liner inspection or rebuild in Elmhurst, the sweep who shows up at your door is background-checked, in uniform, and gave you a real arrival window. If that window slips, we call. You’ll never be left waiting on a four-hour “sometime” window.
Ask anyone on your street. Elmhurst homeowners have dealt with national outfits that quote one price on the phone and a different one at the door. We do the opposite: the number you hear is the number on the invoice, and it’s locked before work begins. Our Chimney Liner & Rebuild team has been inside more of these rowhouse flues than we can count.
Our Chimney Liner & Rebuild Services in Elmhurst
Stainless Steel Liner
A stainless liner is the right fix for the vast majority of Elmhurst rowhouses, especially the ones built in the 1920s and 1930s where a gas boiler got connected to an unlined masonry flue. We pull a DuraFlex or Gelco stainless liner through the existing flue, insulate it where the code requires, and connect it properly to your appliance. For a typical two-story rowhouse off Broadway or Whitney Avenue, that’s a one-day job in most cases.
Flexible Liner
Elmhurst’s attached homes often have flues with slight offsets or irregular interior dimensions, which makes a flexible liner the practical choice. We stock the common lengths so we’re not running back to a supplier mid-job. Flexible stainless liners from Famco or Olympia Chimney handle the acidic condensate from gas appliances far better than the old terra cotta or unlined masonry ever did.
Liner Replacement
When the existing liner is cracked, delaminating, or simply missing, replacement is not optional. It’s structural. In Elmhurst, we see liners that were installed during 1980s and 1990s oil-to-gas conversions, and many have failed. The black streaking you see during a cleaning is often the first sign. We’ll show you the camera footage and give you a plain-English verdict, every time.
Partial Rebuild
When the flue itself is salvageable but the crown has spalled or the top courses of brick are loose, a partial rebuild makes sense. On Elmhurst’s rowhouse blocks, we’re typically rebuilding the exposed stack above the roof line, repointing the brick, and pouring a proper concrete crown with a drip edge. This stops water from getting into the shared party wall and frost from cracking it further.
Full Chimney Rebuild
Some of Elmhurst’s oldest attached homes need the whole stack rebuilt from the roof up, or even from the firebox to the cap. It’s a bigger job, usually two to three days with scaffolding set in a narrow rear yard or on the roof. We’ll walk you through the actual condition with photos before recommending something this involved. Nothing gets recommended without camera evidence you can see for yourself.
Liner Repair
Not every liner problem requires full replacement. We use HeatShield and other proven repair materials to seal minor cracks and gaps in otherwise sound clay liners. But we’ll be honest with you: on Elmhurst’s unlined and oversized flues, a patch is sometimes not the right fix. When it won’t hold, we’ll tell you that and show you why.

Trusted Brands We Service in Elmhurst
We install and service products from DuraFlex, HeatShield, Gelco, Olympia Chimney, and Famco. These are the brands we trust, and we stock the common parts locally so an Elmhurst job doesn’t stall waiting for a shipment. Whether it’s a DuraFlex stainless liner going into an unlined rowhouse flue or HeatShield sealing a cracked clay liner, we use materials sized for the appliance, not whatever’s on the truck. For Elmhurst’s converted gas flues, the liner material matters more than most people realize.
Common Chimney Liner & Rebuild Problems We See in Elmhurst Homes
- Oversized flues from fuel conversions. Many Elmhurst rowhouses were built for coal, switched to oil, then switched to gas. The flue was sized for coal and oil, which means a modern gas appliance vents into a cavity far too large. The result is acidic condensate that eats mortar from inside and triggers DOB liner requirements when you pull a permit for a new boiler.
- Shared party-wall chimneys with multiple flues. On attached brick homes, several units may vent through one shared stack. Identifying which flue belongs to which apartment requires camera work and sometimes access to a neighbor’s roof. Misdiagnosis here is dangerous; exhaust can end up in the wrong unit.
- Crown and cap deterioration from Queens freeze-thaw cycles. The repeated freezing and thawing of water on exposed brick crowns and caps accelerates spalling. On many Elmhurst rowhouses, crowns have gone 30 to 50 years without repointing. By the time we’re called, water has already worked into the shared party wall.
- Rooftop access problems on narrow streets. Getting to the chimney on an attached rowhouse often means working across a neighbor’s parapet or setting up from a rear yard with barely enough room for a ladder. It takes someone who’s done it before. We do it all the time in Elmhurst.
Pricing for Chimney Liner & Rebuild in Elmhurst, NY
Here’s what you’re looking at in Elmhurst, honestly. A straightforward stainless steel liner replacement in a single-family rowhouse runs $1,800 to $3,400, including the liner, insulation, top plate, and connection work. A partial rebuild with repointing and a new crown runs $2,200 to $4,800. A full chimney rebuild, where we’re taking the stack down to the roof line and rebuilding it, runs $4,500 to $8,500 depending on height, access, and the condition of what we’re tying into. Liner repair with HeatShield starts around $800 and goes up depending on how many feet of flue need sealed. These ranges reflect Elmhurst’s specific reality: attached homes, shared stacks, and the compliance work that often comes with a liner discovery. Call (929) 822-6306 for an exact quote. Estimates are free, and we’ll show you the camera footage that justifies every recommendation.

FAQs - Chimney Liner & Rebuild in Elmhurst
Usually yes, but it depends on the stack’s internal layout. Most Elmhurst party-wall chimneys have separate flues for each unit, even though they share brickwork. We camera each flue to identify exactly which one is yours, then reline only that flue. We don’t touch the neighbor’s side unless there’s a safety issue that requires it, and in that case we’ll talk through your options before doing anything. Call (929) 822-6306 and we’ll camera your flue first.
Yes. If your existing flue is unlined, oversized, or cracked, the NYC Department of Buildings will require a code-compliant liner before it will issue a permit for a replacement boiler or water heater. This is one of the things that makes Elmhurst different from Nassau County. The flue that worked for an old oil burner often can’t legally serve a new gas unit, and a permit triggers the compliance work. We install the liners that satisfy the DOB requirement, and we’ll give you the documentation your contractor needs.
In most cases, you need the liner replaced and the surrounding masonry evaluated. The black streaking comes from acidic condensate eating the mortar from inside, which means the liner has failed or was never there. If the brick is still structurally sound and the crown is intact, a stainless liner fixes the problem without a full rebuild. We’ll show you the camera footage so you can see exactly what we’re seeing before you spend a dollar. Call (929) 822-6306 for a free estimate.
Carefully, and with the right equipment. Most Elmhurst rowhouses give us roof access from a rear yard or via a neighbor’s parapet with their permission. We carry narrow scaffolding sections sized for Queens rear yards. Sometimes we need a day to coordinate access before we start. It’s part of why working with a crew that knows Elmhurst’s layout beats a franchise that rotates a new tech through every spring.
Yes, and this is exactly the kind of issue we look for on Elmhurst party-wall stacks. If a new gas boiler was connected to an oversized or unlined shared flue, condensation and draft problems can push exhaust into the wrong unit. Or the neighbor’s flue may have been misidentified and tapped into yours. Stop using your fireplace until we’ve looked at it. Call a licensed sweep immediately. We’ll camera the shared stack, identify which flue is which, and fix the cross-contamination properly. Call (929) 822-6306 and we’ll come out.
If you’re in Elmhurst and you’ve got a liner problem, a draft problem, or a contractor telling you that your chimney needs work before a permit will go through, call us at (929) 822-6306. We’ll send the camera up, give you an honest read on what’s there, and price the job before any tool comes off the truck. The number you hear is the number you’ll pay. And the 90-Day Done Right Promise is in writing, on every single job.
