HeatShield Chimney Cap & Crown in Hempstead: What to Know First

We repair and replace HeatShield chimney caps and crowns in Hempstead every week, and most jobs are done in a single visit. A typical cap replacement runs $340-$650 depending on the flue size and whether it’s a standard single-flue cap or a multi-flue setup. Crown repairs usually land between $450 and $900, and we’ll give you that number before a single tool comes off the truck.

This page is for Hempstead homeowners who already have a HeatShield product on their chimney and are seeing rust on the cap, cracks in the crown, or water showing up in the firebox. If that sounds like your house, call (516) 963-1068 and tell us what you’re seeing. We’ll talk it through and let you know if it’s urgent or if it can wait.

How HeatShield Products Fail - and How We Fix Them

HeatShield makes a solid product line, but no cap or crown survives Hempstead winters forever. Salt air from the South Shore, freeze-thaw cycles, and the age of the chimneys around here all take their toll. Here’s what we actually find when we get on the roof:

• Rust-through on HeatShield single-flue caps. The mesh screening on the side panels is usually the first thing to go. Once the mesh rusts out, birds get in, and the cap’s frame starts corroding from the inside. We see this most on homes near Hofstra University where chimneys are 40-plus years old and the original cap was never upgraded. The fix is usually a full replacement, not a patch.
• Crown cracking around the flue tile. A HeatShield crown that was poured too thin, or one that’s been hammered by Hempstead’s freeze-thaw cycles, will crack where the flue tile meets the crown surface. Water gets under the crack, freezes, and widens it. This is worth catching early because a crown crack is a fast track to liner damage and spalling brick. We clean, fill, and coat the crown with a flexible sealant that moves with the chimney instead of fighting it.
• Improper cap fit on HeatShield relined chimneys. We see this a lot: someone had a HeatShield liner installed, and the old cap was just set back on top without being sized to the new flue. That leaves gaps where rain gets in and where sparks can get out. We’ll measure the actual flue opening and fit a cap that matches it, whether that’s a HeatShield OEM unit or a properly spec’d aftermarket cap.
• Corrosion at the cap-to-crown seam. HeatShield caps that sit directly on the crown without a proper bed of sealant will trap moisture at that seam. The caulk dries out, water sits against the metal, and you get rust bleeding down the crown face. We clean the whole seam, reseat the cap, and bed it with high-heat sealant rated for outdoor exposure.
• Multi-flue caps pulling loose in wind. Hempstead gets gusty, especially in the fall and spring along the Meadowbrook corridor. A HeatShield multi-flue cap that’s anchored with short screws into old, soft brick will eventually work its way loose. We see caps leaning, rattling, and in the worst cases hanging half off. The fix is longer anchors set into solid brick, not into the crumbling mortar joint.

Our HeatShield Chimney Cap & Crown Process

We don’t do mystery work. Here’s what a HeatShield job looks like when you call us:

1. 1
   You call, we talk. You tell us what you’re seeing: water in the firebox, rust streaks on the brick, a cap that looks like it’s seen better days. We’ll give you a straight answer on whether it’s a priority or a can-wait.
2. 2
   We get on the roof. Wendell Pike and his crew inspect the cap, the crown, and the top few feet of the flue. Photos and camera footage are part of every inspection, no exceptions.
3. 3
   We show you what we see. Before we quote anything, you’ll see the same photos we took. If the cap’s fine and the crown’s the problem, that’s what we’ll say. If the reverse is true, same story.
4. 4
   We make the parts call. For HeatShield work, we’ll use an OEM part when it’s the right fit and the warranty depends on it. When an aftermarket cap from a brand like DuraFlex or Gelco does the same job better or cheaper, we’ll tell you that too. You decide.
5. 5
   We do the work and test it. Cap installed, crown coated, seams sealed. Then we run a smoke test or a water test depending on the job. If it doesn’t pass, it’s not done.
6. 6
   You get the paperwork. The price you approved is the price on the invoice. And the 90-Day Done Right Promise is stamped right on there. If something’s not right, one call brings us back.

What HeatShield Chimney Cap & Crown Costs in Hempstead

Here’s the honest range for Hempstead homes, based on what we’ve actually billed over the last few years:

• Standard single-flue HeatShield cap replacement: $340-$500 installed, depending on flue size and roof height.
• Multi-flue or custom HeatShield cap: $500-$800. Custom sizing runs higher.

What moves the price: roof pitch and height, how many flues, and whether the existing crown is worth saving. We don’t charge a trip fee for calls inside Nassau County, and we’ll give you the number before the ladder goes up. Call (516) 963-1068 for a free, no-pressure estimate.

Why Hempstead Homeowners Call Top Hat Chimney for HeatShield Work

We’ve been doing this since 1999, and we’ve worked the neighborhoods around Hempstead long enough to know the chimneys, not just the brand names. When a HeatShield cap fails on a 1950s colonial off Peninsula Boulevard, we know what we’re going to find before we go up there. That kind of local knowledge doesn’t come from a franchise playbook.

We work with HeatShield, DuraFlex, and Gelco because different jobs call for different parts, and we’d rather have options than push one brand no matter what. If it doesn’t need doing, we’ll tell you. That’s not a slogan. It’s how we’ve stayed in business for over 29 years, and it’s why your neighbor will tell you the same thing if you ask anyone on your street.

Every HeatShield job gets the same treatment: upfront pricing, photos you can actually see, a background-checked crew in uniform, and our 90-Day Done Right Promise in writing. Call (516) 963-1068 and a live person will answer. It might even be Wendell.
