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 Hempstead
A chimney liner replacement or rebuild in Hempstead typically costs $2,800 for a basic stainless steel liner install and runs upward of $7,000 to $12,000 for a partial or full rebuild, depending on how much of the original masonry is still sound. That’s the honest range before anyone has looked at your flue, and it’s the range we’ve been working in since Wendell Pike started Top Hat Chimney in 1999. If you’re in Hempstead and suspect your liner is failing or your chimney is spalling, call (516) 968-5380 and we’ll schedule a camera inspection first.
We work the older neighborhoods here regularly, the Cape Cods off Peninsula Boulevard, the colonials west of Clinton Street, the split-levels near Hempstead Turnpike. Our Chimney Liner & Rebuild team knows what these houses are hiding before we even set up the ladder. Hempstead’s housing stock was thrown up fast after the war, and the chimneys are now well past their intended service life. We’ll show you exactly what’s happening inside yours before we quote a single dollar of repair.
Why Top Hat Chimney Is Hempstead’s Preferred Chimney Liner & Rebuild Company
Ask anyone on your street. Wendell has been inside more Hempstead chimneys than he can count, and he runs into the same homeowners again on Saturday. That changes how we work. We don’t send a stranger in a wrapped van who quotes one number on the phone and another at the door. Wendell puts his name and license number on every job, and the office is answered by a live person around the clock. It may well be Wendell himself picking up.
Our Hempstead customers tend to be people who’ve already been burned by a national outfit once. They want a name they can verify and a face they’ll see again in town. That’s what we are. Every completed job carries our 90-Day Done Right Promise in writing. If the liner draft or the rebuilt crown isn’t right, one call brings the crew back at no additional cost. We also offer a free second opinion on any written estimate you’ve received from another company. No trip charge inside the county. Ten percent off always for seniors and veterans.
We don’t ask you to trust us on faith. We ask you to watch the camera footage with us. The camera footage and a plain-English verdict, every time, no exceptions. If your chimney doesn’t need a liner, Wendell will tell you that too. That’s the difference between a sweep who lives with his reputation and a franchise that rotated in last spring.
Our Chimney Liner & Rebuild Services in Hempstead
Stainless Steel Liner
The workhorse repair for Hempstead’s aging chimneys. A stainless steel liner sized to your actual appliance, whether it’s a gas furnace, a boiler, or a wood stove, restores proper draft and stops acidic condensate from eating what’s left of your clay tile. We install DuraFlex liners most often in Hempstead because they hold up to the salt air and the freeze-thaw cycles that punish south shore masonry. A typical stainless steel liner install in Hempstead runs $2,800 to $4,500 depending on flue height and access.
Flexible Liner
When the existing flue has bends, offsets, or misshapen tiles, a flexible liner snakes through without tearing down the chimney. In Hempstead’s older Capes and colonials, those 60-year-old flues are rarely straight. We’ll scope the chimney first, show you the path, then pull the liner through. Flexible liners we install in Hempstead typically run $3,000 to $5,200, including the top plate, cap, and connector.
Liner Replacement
The most common job we do in Hempstead is pulling out a clay tile liner that has flaked apart from acidic condensate and replacing it with a properly sized stainless steel liner. This is the fix for the oil-to-gas conversion problem that plagues this town’s housing stock. A liner replacement in Hempstead runs $2,800 to $4,800 for a straight flue, and we handle the permit paperwork for you.
Partial Rebuild
When the liner is shot but the chimney itself is mostly sound, we remove and rebuild only the failing sections. That usually means the top five to ten courses of brick, the crown, and the shoulder, which is where Hempstead’s salt air and nor’easters do the worst damage. A partial rebuild in Hempstead typically runs $4,500 to $8,000, depending on how far down the damage goes. We won’t know until the camera shows us.

Trusted Brands We Service in Hempstead
We install and service liners and components from HeatShield, Gelco, and Olympia Chimney, because these are the brands we’d put in our own homes. We keep common liner diameters and top plates stocked for fast turnaround on Hempstead jobs, so you’re not waiting two weeks for a part to ship. If your existing liner is a HeatShield or Gelco system and it’s failing, we can tell you why and whether it’s worth repairing or replacing outright. No brand loyalty for its own sake. Just the right material for the flue and the appliance venting into it.
Common Chimney Liner & Rebuild Problems We See in Hempstead Homes
- Oversized clay flues from oil-to-gas conversions. Hempstead’s post-war Capes and colonials were built for No. 2 fuel oil, which needs a big, hot-burning flue. Convert to an 80 or 90 percent efficient gas furnace without relining, and that oversized flue never gets hot enough to push out all the combustion gases. Those gases condense, turn acidic, and eat the clay tile from the inside out. The damage is invisible without a camera.
- Salt air pitting the crown and upper brick courses. Hempstead sits roughly 8 to 10 miles from Jones Beach as the crow flies, close enough that Atlantic salt rides the wind and settles on chimney crowns. It accelerates mortar erosion and brick spalling on the upper courses faster than in inland Nassau towns. Then the nor’easters bring hard freeze-thaw cycles that pry the cracks wider every winter.
- Eroded mortar joints on single-wythe brick chimneys. Many Hempstead chimneys were built with a single wythe of brick and no real waterproofing. After 60 to 80 years, the mortar joints are fully eroded, letting water into the firebox and smoke chamber. By the time the homeowner sees the water stain on the ceiling, the liner has usually been compromised for years.
- Rusted dampers and first-degree creosote in converted flues. Even when the liner is technically intact, we regularly find rusted dampers and creosote buildup in Hempstead chimneys that now vent gas appliances. It’s a sign the flue was never sized down. First-degree creosote is a brush job. Third-degree is a glaze. Catch it early and you spend a few hundred dollars instead of a few thousand.

FAQs - Chimney Liner & Rebuild in Hempstead
Because Hempstead’s postwar housing stock was almost entirely built for No. 2 fuel oil, which burns hot and needs a large flue to carry the exhaust. When those homes converted to 80 to 90 percent efficiency gas furnaces, the flue became oversized for the cooler, lower-volume gas exhaust. Those gases condense inside the clay tile, form acidic condensate, and flake the tile apart from the inside. You can’t see it without a camera, but it’s happening in tens of thousands of Hempstead chimneys right now. Call (516) 968-5380 and we’ll scope yours before it becomes a rebuild.
Yes. Hempstead’s position 8 to 10 miles from Jones Beach means salt-laden Atlantic air constantly moves over the town. That salt settles on chimney crowns and upper brick courses, accelerating mortar erosion and brick spalling. The damage is most visible on the top few courses, but the real problem is that once the crown cracks, water gets into the liner cavity and starts a freeze-thaw cycle that widens every crack. If your liner is already compromised, salt air makes it worse faster. Call (516) 968-5380 to have the crown and liner checked together.
It’s common, but it’s not safe. Hempstead’s Cape Cods and colonials from the 1945 to 1965 building boom almost universally have their original clay tile liners, which were designed to last about 50 years. Yours is now 60 to 80 years old. If the house also converted from oil to gas at some point, the liner has likely been degrading from acidic condensate for decades. The only way to know is a camera inspection. We don’t recommend relining anything without showing you the footage first. Call (516) 968-5380 and we’ll schedule the scope.
No. We won’t quote a liner replacement or a rebuild until you’ve watched the camera footage with us and we’ve explained in plain English what we’re seeing. This is the single most important protection a homeowner in Hempstead has against being sold work they don’t need. The camera footage and a plain-English verdict, every time, no exceptions. If the liner is fine, Wendell will tell you it’s fine and you’ll pay for the inspection and nothing else. Call (516) 968-5380 to book the scope.
For a gas furnace in a Hempstead colonial, we almost always install a properly sized stainless steel liner, typically a DuraFlex, that matches the flue dimensions to the furnace’s BTU output. The key is sizing. An oversized liner will condense and corrode, which is the exact problem we’re usually there to fix. A flexible liner works well in colonials because the existing flue often has offsets. The installed cost for a gas furnace liner in Hempstead runs $2,800 to $4,500. Call (516) 968-5380 for an exact quote on your flue. Estimates are free.
