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.

AfterHeatShield Chimney Repair in Hempstead: What to Know First
HeatShield chimney repair in Hempstead is typically a one-day job, and the honest answer on cost is $400 to $1,400 for most liner repairs, depending on how much footage needs the CeCure or joint treatment. We’re an independent HeatShield service provider, which means we install and repair the product but we’re not owned by the manufacturer. That matters because we’ll tell you plainly when a repair will hold and when you’re better off with a new liner. If you own a HeatShield liner and something’s not right, call us at (516) 963-1068 and Wendell or his crew will figure out what’s actually going on before you spend a dime.
This page is for Hempstead homeowners who had HeatShield installed or inherited it when they bought the house. You’ve probably got questions the manufacturer’s website won’t answer. We’ve been inside enough Hempstead flues to answer them straight.
How HeatShield Products Fail, and How We Fix Them
HeatShield wasn’t built to fail fast. It was built to buy you time. The product is a ceramic-modified coating applied inside an existing clay tile liner to seal cracks and gaps. It works, but it has its own weak points. Here’s what we actually see in Hempstead homes:
- Joint separation at the tile transitions. HeatShield’s CeCure product bridges the mortar joints between clay tiles, but in older Hempstead chimneys those tiles have shifted over decades. When the underlying structure moves a quarter-inch, the coating cracks right along the seam. We see this most in homes built before 1960 near the Turnpike corridor. The fix is re-application at the joint, but first we check whether the tile shift is still active. If it is, the repair won’t hold, and you should know that before paying for it.
- Pinhole leaks at the mortar wash line. The area just below the crown is where HeatShield coatings take the most abuse in Hempstead winters. Freeze-thaw cycles push moisture into the masonry, and the coating delaminates in coin-sized patches. The homeowner sees a rust stain on the damper and thinks the liner is shot. About half the time, it’s a localized patch job, not a full reline. Our camera inspection tells us which one you’ve got.
- Flaking around the smoke shelf. HeatShield’s spray-applied Cerfractory product can thin out where the coating has to follow the tight radius of the smoke shelf. We find flaking there more often in chimneys that saw heavy wood-burning through two or three Hempstead winters. The fix is a localized re-coat, but the prep matters: if we don’t get the surface clean back to solid material, the new layer won’t bond. That’s the step the national chains rush through and wonder why the callback comes six months later.
- Improper initial installation showing up years later. HeatShield is only as good as the prep underneath it. The coating needs a clean, dry, properly profiled surface. When an installer skips the scrubbing or applies it over third-degree creosote glaze, the liner looks fine for a couple years and then starts failing in sheets. In Hempstead, we’ve pulled pieces of HeatShield out of fireplaces that look like potato chips. The manufacturer’s warranty won’t help you there. Our repair is to strip the failed sections and recoat properly, which is labor-intensive work that most contractors won’t quote because they don’t want to stand behind it.
- Top plate and cap interaction failures. HeatShield protects the flue walls, but it doesn’t seal the top of the liner. In Hempstead, where we get real rain and coastal-driven wind, water comes down the flue opening and runs behind the coating at the top course of tile. Homeowners mistake the resulting stain line for a failed coating when it’s actually a cap or top plate problem. We fix the cap and patch the top six inches of liner, and that solves it. But we’ve seen homeowners pay for a full recliner when that’s all it needed.
Our HeatShield Chimney Repair Process
Here’s how a HeatShield repair goes when you call Top Hat Chimney:
- 1
You call (516) 963-1068. A live person picks up, day or night. It might be Wendell himself. You tell us what’s going on, and we give you a straight answer about whether it sounds urgent or can wait.
- 2
We schedule a real arrival window. No “somewhere between Tuesday and Friday.” We show up when we say we will. If we’re running late, we call. You don’t chase us.
- 3
We inspect with a camera. This is non-negotiable on every HeatShield job. We run the camera from the firebox to the crown. You see the footage. We tell you in plain English what’s wrong, what’s causing it, and what it will cost to fix. The price you hear before we start is the price on the invoice.
- 4
We make the parts call with you. For HeatShield repairs, we use genuine HeatShield materials when the repair is under warranty or when the manufacturer’s spec requires it. When the warranty has expired and an equivalent aftermarket coating does the same job for less, we tell you that and let you decide. We carry HeatShield CeCure and Cerfractory products on the truck, along with DuraFlex and Gelco options if the verdict is that a reline makes more sense.
- 5
We do the repair and we test it. After the coating cures, we run the camera again and we check draw with a smoke match or draft gauge. The repair isn’t done because the invoice says so; it’s done because the flue moves air the way it should.
- 6
The 90-Day Done Right Promise is on your invoice, in writing. If something’s not right, one call brings us back at no additional cost. Wendell puts his name on that. Every time.
What HeatShield Chimney Repair Costs in Hempstead
HeatShield repair pricing in Hempstead breaks down by what’s actually wrong, not by what a sales guy thinks he can get out of you. Here are the numbers we quote most often:
- Localized joint repair or patch coating: $400 to $750 depending on the number of joints and access difficulty.
- Half-liner recoat using CeCure: $800 to $1,400 for typical Hempstead chimneys (15 to 25 feet of flue).
- Full HeatShield Cerfractory application: $1,400 to $2,200, and only when the existing liner is still structurally sound enough to justify coating rather than relining.
- Cap or top plate replacement paired with a top-course liner patch: $300 to $650.
- Camera inspection as a standalone service: $200, but we credit it toward any repair we do within 30 days.
What moves the price in Hempstead: roof pitch, total flue footage, whether we need a second man on ropes or a lift, and how much prep the old coating requires. A chimney that’s been burning wet wood for ten years costs more to prep than one that’s been swept yearly. We’ll give you a firm number before any work starts. Call (516) 963-1068 for a free estimate, and remember: seniors and veterans get 10% off, always, and any repair over $200 takes $40 off.
Why Hempstead Homeowners Call Top Hat Chimney for HeatShield Work
We’ve been at this since 1999. Wendell Pike founded Top Hat Chimney and he still shows up on the roof, camera in hand, thermos nearby. He learned the trade at Southwestern College in Chula Vista and spent the years since on actual rooftops, including plenty of calls near Hofstra University where older Hempstead homes run older chimneys. If it doesn’t need doing, he’ll tell you. That honesty has cost us jobs over the years, and it’s also the reason we’re still here with a full schedule and a phone that rings from homeowners who got burned by a franchise that quoted one price and left another.
We’re not authorized by HeatShield, and we don’t pretend to be. We’re independent, which means our loyalty is to you, not to a manufacturer’s quota. If your HeatShield liner can be repaired, we’ll repair it. If it’s reached the end of its useful life and a DuraFlex or Gelco reliner serves you better, we’ll tell you that too and show you the footage to back it up. The camera footage and a plain-English verdict, every time, no exceptions.
We answer calls around the clock with a live person. We publish our address and license number. We write the 90-Day Done Right Promise on every invoice. And when we finish a job in Hempstead, we know we’re going to run into you at the gas station or the school pickup line. That’s the real guarantee, and it’s the one the national chains can’t fake.
FAQs
That depends on who does the repair and what materials they use. HeatShield’s warranty generally requires that repairs be done with manufacturer-approved materials and processes. We use genuine HeatShield CeCure and Cerfractory products on warranty-covered work, so the repair itself doesn’t create a warranty problem. If your warranty has already expired, we’ll talk through aftermarket options that perform just as well for less money. Call (516) 963-1068 and we’ll walk through your specific situation.
Most HeatShield repairs in Hempstead are done in a single day. A localized joint patch takes a few hours. A full recoat takes a full day including prep, application, and cure time. We schedule the job so you’re not waiting around, and we leave the firebox cleaner than we found it.
You’ll usually see signs before anything dangerous happens: flaking material in the firebox, a rust stain on the damper, or a smoky smell even when the damper is open. The only way to know for sure is a camera inspection. We run the camera, you watch the footage with us, and we tell you what it means. In Hempstead, we’ve inspected plenty of HeatShield liners that looked bad from the top but were fine below the first six inches. And we’ve seen ones that looked fine from the firebox but were crumbling mid-flue. The camera settles it.
HeatShield can often be repaired in older chimneys as long as the clay tile structure underneath it is still sound. If the tiles themselves have shifted or collapsed, HeatShield can’t replace structural integrity, and you’ll need a reliner or a rebuild. The homes near Hofstra and down toward the turnpike tend to have original chimneys from the 1940s and 50s, and we’ve repaired HeatShield in many of them. We’ve also told homeowners honestly when the masonry itself was too far gone. That’s the benefit of an independent eye.
We book by the week, not the month. If you’re seeing water stains or flaking material and you’re worried about burning season, call (516) 963-1068 and tell us what’s going on. We’ll give you an honest read on urgency and get you slotted in. For most Hempstead homeowners, we can be on-site within a week, often sooner in fall when our schedule opens up after the spring rush.
If your HeatShield liner is showing signs of wear, don’t guess. Call Top Hat Chimney at (516) 963-1068 for a free estimate. We’ll send a background-checked sweep in uniform, run the camera, and show you exactly what’s going on inside your flue. No pressure, no bait-and-switch, and no charge for the trip if you’re in the county. If it doesn’t need doing, Wendell will tell you that too.
