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 Fireplace Services Across Hempstead
Most fireplace work in Hempstead isn’t about the fire you see. It’s about the flue you don’t. After 29 years of working chimneys across Nassau County, we can tell you that a Hempstead homeowner’s fireplace problems almost always trace back to two things: salt air eating the masonry from outside, and old oil-era flues rotting from inside after a gas conversion. If you live in Hempstead and your fireplace draft is weak, your damper sticks, or you smell something odd when the furnace kicks on, call (516) 968-5380. We’ll send someone who knows exactly what he’s looking at, and he’ll show you the camera footage before recommending a dollar of work.

Why Top Hat Chimney Is Hempstead’s Preferred Fireplace Services Company
Wendell Pike founded Top Hat Chimney in 1999, and he still answers the phone. That matters in Hempstead because this is a town where word travels fast. Ask anyone on your street about the national chain that quoted one price over the phone, sent a stranger in a rental van, and disappeared when the work didn’t hold. We’ve heard that story on nearly every block from the Hempstead Turnpike corridor to the residential streets north of Hempstead Village. Our answer has always been the same: Wendell puts his name on the work, publishes his license number, and hands you a written 90-Day Done Right Promise on every single job. If it’s not right, one call brings him back. No charge. No argument.
Our crews serve Hempstead daily, and we’ve run more camera inspections through 1950s Cape Cods and split-levels in this town than any franchise outfit will ever see. When a Hempstead homeowner calls, they get a live person on the line, a real arrival window, and a sweep who shows up in uniform with a background check on file. The pricing you hear on the phone is the number on the invoice. That’s not a marketing line. It’s how we’ve stayed busy in Hempstead for years while the chains churn through new logos.
Our Fireplace Services in Hempstead
Wendell and his crew handle the full range of Fireplace Services work in Hempstead, from routine service calls on gas units to full conversion projects on original wood-burning hearths. Here’s what we handle most often in this town.
Gas Fireplace Service
Gas fireplaces in Hempstead houses built between 1945 and 1965 were usually retrofit into an existing masonry hearth that originally burned wood or coal. The venting for those units is frequently wrong for a gas appliance: too large, too cold, and condensing acidic exhaust inside the original clay tile. Our gas service includes checking the vent path, cleaning burners and logs, testing the thermocouple, and verifying the damper is correctly set for a gas unit. In Hempstead, we typically run $175 to $325 for a standard gas fireplace service call, depending on the unit.
Wood Burning Fireplace
A wood-burning fireplace in a Hempstead home needs more than a sweep. The smoke chamber on these original chimneys was built by hand, with corbeled brick that catches creosote in ways a rotary brush can miss. We inspect the firebox, damper, smoke chamber, and flue on every wood fireplace service. If you’re burning wood in Hempstead, the salt air is working on your crown and upper courses the whole time. A sweep and inspection here runs $189 to $289. If we find glaze creosote, we’ll tell you and show you the footage before we talk about removal.
Fireplace Insert
Hempstead homeowners who want heat, not ambience, often ask about inserts. A properly sized insert solves two problems at once: it stops heat loss up an oversized flue and it vents through a correctly sized stainless liner instead of a deteriorating clay tile. We install and service inserts from Olympia Chimney and Copperfield, and we’re honest about whether your existing firebox can handle one without major mason work. Most insert installs in Hempstead run $3,800 to $6,500 including the liner, but we’ll give you a firm written number before anything comes off the truck.
Damper Repair
The damper on a Hempstead fireplace often fails because water has been getting in around the flashing and dripping onto the damper assembly for years. Salt air accelerates this. By the time a homeowner notices the damper won’t open or won’t seal, there’s usually rust or warping below the throat. Replacing a damper here runs $250 to $650 for a standard top-sealing or throat damper. If the firebox itself is spalled from water damage, that’s a different discussion, and we’ll show you the camera evidence before recommending it.
Trusted Brands We Service in Hempstead
We stock parts for Gelco and Famco dampers, and we install and service inserts from Olympia Chimney and Copperfield. For relining work on Hempstead’s gas-converted Cape Cods, we use DuraFlex stainless, which is the right answer for low-BTU gas exhaust in an oversized flue. Because we keep these components on hand, a Hempstead homeowner usually doesn’t wait a week for a part to ship. If you already have a Gelco damper or a Famco top-sealing unit, we can service it. If you need one, we’ll quote the right brand for the application and stand behind the install.
Common Fireplace Problems We See in Hempstead Homes
Here’s what we actually find when we run a camera through a Hempstead fireplace:
- Oversized clay flues after oil-to-gas conversion. Homes built for No. 2 fuel oil had flues sized for a big, hot burn. A modern 80% gas furnace or fireplace vented through that same flue produces cooler, wetter exhaust that condenses and eats the clay from the inside out. Homeowners never see it. Camera inspection always does.
- Salt-driven spalling on crowns and upper courses. Hempstead sits close enough to Jones Beach that Atlantic air reaches the masonry. Salt crystals get into the mortar pores, dry, and expand, which cracks the crown and lets water behind the brick. This fails faster here than in Levittown or Oceanside, and it always starts at the top before you notice it at the firebox.
- Freeze-thaw widening from nor’easters. Every nor’easter pushes rain into existing hairline cracks. Winter freeze cycles wedge those cracks open a little more each year. By the end of a few Hempstead winters, water is dripping down behind the flashing and onto the damper assembly.
- Damper failure from hidden moisture. The first thing that fails on a coastal chimney is usually not the firebox. It’s the damper. Rust from roof leaks or flashing failures binds the damper plate, and one day it simply won’t move. That’s the early warning sign of bigger water intrusion.

FAQs - Fireplace Services in Hempstead
Why do Hempstead’s 1950s-era chimneys fail differently than newer homes?
Because they were built for oil. A Hempstead Cape Cod or colonial from the 1945-1965 housing boom has a single-wythe brick chimney with a clay tile liner sized for a high-BTU oil burner. When that home converted to a low-BTU gas furnace, the liner became oversized, flue gases cooled too fast, and acidic condensate has been eating the clay ever since. Newer homes built after the 1980s have correctly sized liners and don’t see this failure mode. If your Hempstead home was built before 1970 and converted to gas, you should have a camera inspection. Call (516) 968-5380 and we’ll schedule one.
How does salt air near Jones Beach actually damage my fireplace chimney?
Salt air at Hempstead’s distance from the Atlantic, roughly 8 to 10 miles from Jones Beach, carries airborne salt that settles on the chimney crown and upper brick courses. Over decades, salt crystals penetrate the porous mortar, exert pressure as they recrystallize, and cause spalling and cracking. The crown goes first, then the upper courses, then the flashing. Hempstead chimneys fail from the top down, faster than inland Nassau County homes. The inspection interval here should account for that.
What’s the inspection interval for a chimney on a gas-converted Hempstead home?
Every two years, minimum. A Hempstead home that converted from oil to gas without relining is running wet, acidic exhaust through an old clay tile every time the heat comes on. That tile is degrading silently. A Level 2 camera inspection every 24 months catches spalling before it becomes a full reline. If you haven’t had one in years, or ever, call (516) 968-5380 and we’ll run the camera. Estimates are free.
What fails first on a coastal chimney in Hempstead?
The crown and flashing, almost always. In Hempstead’s salt-laden air, the crown takes on water, cracks under freeze-thaw pressure from nor’easters, and lets moisture down behind the flashing. The damper assembly is usually the first thing the homeowner notices, because rust binds the plate and the handle stops moving. That’s the tell. If your damper is stiff, there is water getting in somewhere above it.
Do you recommend stainless or galvanised components for Hempstead chimneys?
Stainless. Always stainless for Hempstead. Galvanised caps, covers, and dampers fail fast here because the salt air and the acidic condensate from gas conversion corrode zinc coatings in a few years. Stainless costs more upfront, but it’s the right material for a chimney 8 miles from the Atlantic. We stock stainless caps and dampers from Famco and other brands for this exact reason. Call (516) 968-5380 and we’ll quote the right components for your house.
One More Thing About Hempstead Chimneys
The housing stock here is unique in Nassau County. Tens of thousands of Cape Cods and colonials went up between 1945 and 1965, all with original masonry chimneys and clay tile liners, all now 60 to 80 years old. When these homes converted from oil to gas, nobody relined the flues. The result is a failure mode we see every week in Hempstead: oversized clay flues condensing low-BTU exhaust, acidic degradation spreading through the tile, and homeowners completely unaware until a firebox repair turns into a full reline. The only way to catch it early is a camera inspection. That’s the information gain this page exists to deliver. We pulled up to a 1952 Cape Cod near the Hempstead Turnpike corridor after the homeowner noticed a faint sulfur smell every time the gas furnace kicked on. Our tech ran a Level 2 camera scan and found third-degree creosote glaze bonding to the smoke chamber, plus the original clay flue liner spalling from years of acidic condensate. We dropped in a properly sized stainless liner, rebuilt the firebox, and sealed the chimney crown against salt-driven spalling, the same fix we’ve made on dozens of Hempstead’s original suburban chimneys. First-degree creosote is a brush job. Third-degree is a glaze. Catch it early.
Call (516) 968-5380 for a free estimate. Wendell answers the phone, and the number he quotes is the number you’ll pay. That’s been true since 1999, and it’s true for every Hempstead home we visit.
