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.
Fast, Reliable Chimney Cap & Crown Across Hempstead
A cracked crown or a missing cap in Hempstead isn’t a small cosmetic issue. It’s an open invitation for Long Island weather to get inside the flue, and on a post-war Cape Cod or colonial, that usually means a repair bill far bigger than the cap itself would have cost. We’re Top Hat Chimney, and our Chimney Cap & Crown team has been up on the roofs of Hempstead’s split-levels and colonials long enough to know exactly what the salt air off Jones Beach does to mortar. Call us at (516) 968-5380 for a free estimate, and Wendell will give it to you straight before a single tool comes off the truck.
For Hempstead homeowners, the short answer: most cap installations run $250-$450, crown repair starts around $350-$650, and a full crown rebuild with coating runs $700-$1,300. Those are honest ranges for this town’s housing stock, and we’ll show you camera footage to back up every dollar before we touch anything.
Why Top Hat Chimney Is Hempstead’s Preferred Chimney Cap & Crown Company
We’ve been sweeping and repairing chimneys in Hempstead long enough to recognize the exact failure pattern before we even get on the ladder. The Town of Hempstead’s post-war building boom left behind tens of thousands of homes with clay tile liners now older than the people who live in them. When Wendell shows up to a house off Peninsula Boulevard or near Hempstead Turnpike, he already knows what the cap and crown have been fighting against for sixty or seventy years.
Hempstead homeowners keep our number because Wendell answers the phone himself, around the clock. Not a call center. Not a voicemail box. And the price he quotes on that first call is the price you see on the invoice. The 90-Day Done Right Promise is written on every single job: if it’s not right, one call brings him back. No fine print, no runaround. A background-checked, uniformed crew arrives with a real window and calls if it slips. And ask anyone on your street who’s used us. Hempstead is not a big enough town for a chimney company to hide behind a brand name. Wendell puts his name on the work and runs into you again at the hardware store on Saturday.
We serve all of Hempstead and the surrounding south shore communities. You may not realize how fast problems compound out here, but we do, and we make sure you see the evidence with your own eyes before anyone recommends a repair.
Our Chimney Cap & Crown Services in Hempstead
Cap Installation
A proper cap keeps rain, snow, squirrels, and birds out of the flue. On a 1950s colonial in Hempstead with a single clay flue, we typically install a stainless or copper single-flue cap that holds up against the salt-laden air rolling in from Jones Beach. Cap installation in Hempstead usually takes under an hour. We’ll show you before and after photos while you’re standing in the driveway.
Cap Replacement
Most Hempstead homes we see have caps that rusted through years ago. A rusted cap doesn’t just look bad. It lets nor’easter rain drive directly down into the flue, which accelerates every other problem. We replace old caps with proper stainless models, sized correctly for the flue. Here’s the part that matters for Hempstead specifically: homes that converted from oil to gas often have a flue that’s too big for the appliance. A one-size-fits-all cap off a shelf won’t address that. We measure, show you the camera footage, and install the right cap for the actual venting situation up there. Copperfield and Gelco are the two brands we recommend most for coastal New York conditions.
Crown Repair
The crown is the concrete or mortar slab that seals the top of the chimney stack. In Hempstead, crown repair is probably the single most common call we get. Freeze-thaw cycles widen hairline cracks every winter. Salt in the air works its way into the pores and spalls the edges. On a 1960s split-level, the crown has already been through sixty winters of that. We cut out the cracked material, rebuild the crown with the proper slope and overhang, and make sure water runs off instead of into the brick. Crown repair in Hempstead typically runs $350-$650 for a standard residential chimney. A full rebuild with larger structural damage may go higher, and we’ll explain exactly why before any work begins.
Crown Coating
For a crown that’s still structurally sound but showing its age, crown coating buys serious time at a fair price. We use HeatShield’s CrownCoat system, which seals the surface against water intrusion without requiring a full teardown. Crown coating on an older Hempstead chimney runs $200-$400. We recommend it often on post-war homes where the crown has minor cracking but the structure underneath is still intact. The camera footage and a plain-English verdict: every time, no exceptions.

Trusted Brands We Service in Hempstead
We install and service components from Gelco, Copperfield, and HeatShield. These are the brands that hold up in a coastal environment where cheap galvanized steel fails in three years and cheap sealants fail in two. Because we’re local to Hempstead, we keep common components close by, which means less waiting when a nor’easter has knocked your cap loose or when a crown needs work before the next storm cycle. If you already have a Gelco cap or a HeatShield coating on your chimney, we’re familiar with it and service it properly. We don’t push a brand you don’t need.
Common Chimney Cap & Crown Problems We See in Hempstead Homes
- Salt-driven mortar erosion. Hempstead sits roughly 8-10 miles from Jones Beach, and the prevailing Atlantic air carries enough salt to accelerate mortar joint breakdown on chimney crowns and upper brick courses. We regularly see crowns that have lost a half-inch of surface in exposed spots, leaving the flue mouth unprotected.
- Nor’easter freeze-thaw cracking. Every winter, water works into hairline cracks, freezes, expands, and wedges them wider. By March, a crown that looked fine in October has visible cracks and a loose cap. Your flue doesn’t care how the fire looks. It cares how it breathes.
- Rusted or missing caps on oil-to-gas conversions. Homes built in Hempstead between 1945 and 1965 were designed for oil burners with large, hot-running flues. Many converted to gas decades ago without resizing the cap or liner. The oversized flue condenses acidic gas exhaust, which eats the cap from underneath. The cap looks fine from the ground and is failing from the inside.
- Oversized clay flues deteriorating from acidic condensate. This is the single most Hempstead-specific failure mode we find. A flue built for No. 2 fuel oil now vents an 80-90% efficiency gas furnace. The exhaust is cooler, condenses sooner, and the acidic condensate corrodes clay tile, the crown underside, and the cap assembly. Invisible without a camera inspection. Rampant in this specific housing cohort.

FAQs - Chimney Cap & Crown in Hempstead
Because Hempstead’s post-war Cape Cods, split-levels, and colonials were built fast, with single-wythe brick masonry and basic mortar crowns that were never designed for sixty-plus years of Atlantic weather. Add salt-laden air from Jones Beach and annual nor’easter freeze-thaw cycles, and those hairline cracks become structural failures. Most of those homes also converted from oil to gas without relining, so the oversized flue condenses acidic exhaust that works on the crown from the inside while the weather works on it from above. Our Chimney Repair in Hempstead starts with camera footage before we recommend anything. Call (516) 968-5380 for a free estimate.
It shortens the life of cheap galvanized caps dramatically. Salt in the air corrodes the metal and the mounting hardware faster than in more inland Long Island towns. We recommend stainless or copper caps for Hempstead homes for exactly that reason. A proper Gelco or Copperfield stainless cap will outlast a big-box galvanized unit many times over in this environment. We’ll show you the difference during your our Fireplace Services in Hempstead visit before you decide anything.
You may. A gas furnace vents cooler exhaust than the oil burner your home was built for, which means the flue is likely oversized for the appliance. That causes condensing, and that condensate is acidic. It eats clay tile, crown mortar, and the underside of the cap. Many Hempstead homeowners have no idea this has been happening inside their chimney. The only honest way to know is with a camera inspection. Wendell won’t sell you a cap you don’t need, and he’ll show you the footage either way. Call (516) 968-5380.
Crown coating seals the surface against water intrusion and buys years of service life without a full teardown. We use HeatShield’s CrownCoat, which is specifically formulated to flex with temperature changes instead of cracking like standard mortar patching compounds. On a 1960s chimney that’s structurally sound but showing surface spalling from salt and freeze-thaw, coating is often the honest, cost-effective answer. If the crown is too far gone, we’ll tell you that plainly and show you why a rebuild is necessary.
Once a year, burn or no burn. Chimneys break in the off-season too. On a 1945-1965 home within ten miles of the ocean, the crown is under assault every single month of the year. An annual inspection with a camera catches a minor crown crack or a rusting cap bracket before it becomes a $1,300 rebuild. Many of our Hempstead customers schedule their Hempstead Chimney Cleaning & Sweep and inspection together in the fall before burning season. The camera footage and a plain-English verdict. Every time. Call (516) 968-5380 to schedule yours.
