We’re Top Hat Chimney, and we provide independent HeatShield service and our Chimney Cleaning & Sweep in Hempstead across Hempstead, NY.

Call (516) 963-1068 and we’ll tell you straight whether your chimney needs HeatShield work or not.

Call (516) 963-1068

We’ve been servicing HeatShield systems since the product hit the market, and we’ve spent 15 of those years working on Hempstead’s pre-1960 masonry stock. We hold Factory-Built Fireplace Certification for HeatShield systems, and our technicians do annual continuing education on HeatShield’s ceramic insulation and refractory repair methods. That matters here because Hempstead’s housing stock throws problems at a chimney that a training video never covers.

Why Hempstead Residents Choose Us for HeatShield Service

Wendell Pike started this company in 1999, and he’s been driving out to Hempstead ever since, including plenty of calls near Hofstra University where older homes and older chimneys tend to go hand in hand. He learned the trade at Southwestern College in Chula Vista and picked up the rest on actual rooftops. If a HeatShield job doesn’t need doing, he’ll say so. That’s probably cost him work over the years, but it’s also why people in Hempstead keep calling back.

We carry genuine HeatShield materials on the truck, not a substitute. We service and install everything HeatShield makes for chimney repair, and our HeatShield sales & service work is backed by the same 90-Day Done Right Promise we put on every job. The price you hear on the phone is the price on the invoice, and a real person answers that phone 24/7. It might be Wendell himself.

Common HeatShield Chimney Cleaning Problems We Solve in Hempstead

• Spalled and dislodged flue tiles in unlined 1920s-1950s chimneys. Hempstead’s Cape Cods and colonials were mostly built without clay tile liners, and the ones that have them are now cracked from decades of freeze-thaw cycling. HeatShield’s Joint Repair System fills those gaps and restores a continuous flue surface.
• Cracked HeatShield Cerfractory coating from oil-to-gas conversions. When a lower-temperature gas appliance vents through a flue sized for oil, condensation forms and acidic byproduct eats at the refractory surface. We see this constantly in Hempstead’s conversion-heavy neighborhoods.
• Deteriorated HeatShield sealant around thimble connections. A lot of Hempstead homes have a gas boiler and fireplace sharing one flue, and that configuration puts stress on the thimble seals. When the sealant degrades, exhaust finds its way where it shouldn’t.
• HeatShield failure from improper original installation. Out-of-area contractors unfamiliar with Nassau County’s grandfathered multi-appliance flue configurations install systems that fail early. We redo those jobs properly.
• Flue damage from salt-laden air. Hempstead sits within 10 to 15 miles of the Atlantic and Great South Bay. Mortar joints that look fine from the ground crumble on contact once you’re on the roof, and that spalled mortar contaminates the flue interior between cleanings.

HeatShield Service in Hempstead: What Local Conditions Mean for Your Equipment

Here’s what you won’t find on any other HeatShield page. Hempstead’s dense stock of 1920s-1950s Cape Cods and colonials, many built with oil-fired boilers sharing a masonry flue with a fireplace, faces a specific crisis as homeowners convert from oil to gas heat. The oversized, unlined flue that worked for oil creates dangerous condensation and acidic byproduct buildup when a lower-temperature gas appliance vents through it. That makes chimney inspection and relining a near-mandatory companion to every fuel-conversion job in the area. This oil-to-gas conversion wave is far more concentrated here than in neighboring Suffolk County towns or Queens, because Nassau County’s post-WWII housing boom locked in oil infrastructure at unusually high rates. For HeatShield owners, that means a Cerfractory coating or CeCure sleeve installed five years ago may now be degrading faster than the product’s rated lifespan because the flue’s temperature profile changed when the new gas boiler went in. We saw this exact scenario last month on Ingraham Boulevard: a 1948 Cape Cod’s flue had fireclay tiles so spalled that the HeatShield Cerfractory couldn’t bond until we removed three courses of loose tile. After applying CeCure sleeves and the joint repair system, we finished with a waterproof crown coating. The closing attorney watched from the side yard.

HeatShield Models & Products We Service in Hempstead

We service the full HeatShield line: the Joint Repair System, the CeCure Sleeve Relining System, HeatShield Flue Sealant, and Cerfractory Flue Sealant. We use only genuine HeatShield materials because improvised refractory products fail within two to three seasons in Hempstead’s salt-laden freeze-thaw conditions. We stock common HeatShield components locally, which means faster turnaround when you need a repair before a closing or a burner inspection. We repair HeatShield systems when they’re structurally sound. We recommend full replacement only when the underlying masonry has lost integrity from spalling or fireplace demolition. If it doesn’t need replacing, we won’t push it.

FAQs - HeatShield Chimney Cleaning in Hempstead

Is HeatShield relining legal for a shared oil-furnace/fireplace flue in Hempstead? Yes, HeatShield relining is code-compliant for shared flues in the Town of Hempstead when performed with proper permits and inspection. Nassau County’s building department requires a permit for chimney liner installations, and HeatShield’s CeCure system is accepted for multi-appliance configurations that meet current code. We handle the permit paperwork as part of the job. Call (516) 963-1068 and we’ll walk you through what your specific house needs.

How does Hempstead’s salt air affect a HeatShield repair after installation? The interior Cerfractory and CeCure surfaces are protected from salt exposure, but the exterior masonry and flashing around your flue are not. Hempstead’s salt-laden air accelerates mortar joint spalling and metal corrosion, which means a HeatShield repair lasts longer when paired with Chimney Repair - Hempstead and chimney waterproofing. We always recommend a crown coating after any interior repair, and we include that in the scope when it’s needed.

Can you inspect my HeatShield liner without a permit in the Town of Hempstead? A visual inspection or camera scan does not require a permit. If the inspection reveals that repair or replacement work is needed, that work will require a Town of Hempstead permit. We pull permits for every job that needs one, and the inspector’s sign-off is part of our process. Call (516) 963-1068 to schedule a camera inspection, we’ll show you the footage and explain exactly what you’re looking at.

What happens if my HeatShield liner was installed by a previous owner but has no paperwork? You can still have the system inspected and serviced. We’ll run a camera through the flue, document the condition, and give you a written report. If Hempstead Village code inspectors need documentation for a real-estate closing, we can provide a condition report that satisfies the inspection requirement. The key is getting the camera evidence before the closing date, so call (516) 963-1068 early in the process.

Does HeatShield work in chimneys with no clay tile liner at all? It does, and that’s the situation in a large share of Hempstead’s pre-1960 homes. HeatShield’s CeCure sleeve can create a continuous insulated liner in a chimney that never had clay tiles, provided the surrounding masonry is structurally sound. We assess the brick condition first, because a spalled single-wythe chimney needs masonry work before any liner system makes sense. For an exact assessment of your chimney, call (516) 963-1068, the estimate is free.
