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.

Why Top Hat Chimney Is Wyandanch’s Preferred Chimney Cap & Crown Company
Wendell Pike started Top Hat Chimney in 1999, and he’s been inside more Wyandanch chimneys than most sweeps have seen in a career. The neighborhood hasn’t changed much in that time. The Cape Cods off Long Island Avenue, the ranches behind the LIRR station, the brick single-chimney homes near Wyandanch Park. He knows what happens to a clay-tile liner when it’s been venting an oil burner for sixty years and then somebody converts to gas overnight. That’s the work we do here more than anything else.
Ask anyone on Straight Path or North 29th Street. The company’s reputation in Wyandanch was built on showing up, doing the job Wendell quoted, and backing it with the 90-Day Done Right Promise in writing. If a crown repair fails or a cap loosens within ninety days, one call brings the crew back at no charge. No arguing, no fine print.
Our Chimney Cap & Crown work is priced before we take a tool off the truck. The number on the phone is the number on the invoice. And every job comes with camera footage of the flue, so you see exactly what Wendell saw. Not a summary. The actual footage.
We’ve worked Wyandanch long enough to know which streets have the shared-flue Capes and which have the larger ranches that ventilate differently. That’s the kind of local knowledge that keeps a small repair from becoming a $4,000 liner job down the road.
Our Chimney Cap & Crown Services in Wyandanch
Cap Installation
A properly sized cap keeps rain, leaves, squirrels, and the occasional nor’easter-driven bird nest out of your flue. In Wyandanch, where most chimneys still have their original clay tile, a cap is often the cheapest insurance you can buy against water damage. We install Copperfield and Gelco caps sized to your flue, not whatever’s on the truck.

Cap Replacement
If your cap is rusted through, blown off in a storm, or was never the right size in the first place, we’ll pull it and put the correct one on. Undersized caps are a common problem in Wyandanch’s 1950s housing stock. The original builder slapped on whatever was cheapest, and fifty years later it’s still there, doing half a job.

Crown Repair
The crown is the concrete slab on top of the chimney. In Wyandanch, with Long Island’s freeze-thaw cycles and nor’easter rain, cracked crowns are the single most common failure point on these aging homes. Water gets in, freezes, widens the crack, and next thing you know you’ve got spalled brick and a liner that’s absorbing moisture. We remove the damaged concrete, pour a proper crown with a drip edge, and seal it so water flows away from the flue instead of into it.

Crown Coating
When a crown is still structurally sound but showing surface wear, we use CrownCoat, a brushable elastomeric sealant that fills hairline cracks and keeps them from opening up. It’s a faster, less expensive option in Wyandanch when the damage hasn’t reached the point of full rebuild. Not every crown needs to be torn out. Wendell will tell you plainly which yours does.

Multi-Flue Cap
Wyandanch’s Capes commonly have two flues side by side. The right fix is a single multi-flue cap that covers both openings and anchors to the crown properly. We stock Gelco multi-flue caps and can fabricate sizes for chimneys that don’t match modern off-the-shelf dimensions.

Custom Cap
Sometimes the flue on a 1950s Cape Cod isn’t rectangular, isn’t round, isn’t standard anything. We measure, order, or fabricate a cap that actually fits. It costs more than a box-store cap, but a cap that fits is the one that stays on through a January nor’easter.

Common Chimney Cap & Crown Problems We See in Wyandanch Homes
- Cracked crowns from nor’easter rain and freeze-thaw cycles. Water pools in the crack, freezes, widens it, and then melts its way into the smoke chamber. By April, the damage inside is worse than what you can see from the ground.
- Missing or undersized caps on shared flues. Rain and debris mix with oil soot and creosote, creating a paste that clogs the flue and gives carbon monoxide a path back into the house. This is the shared-flue hazard we find most in Wyandanch’s un-renovated Capes.
- Spalled brick and corroded mortar on single-brick chimneys. When the brick face starts popping off, the cap and crown lose their anchor. The cap tilts, the crown cracks, and water gets everywhere. Spalling on a Wyandanch chimney means the crown work has to address the masonry, not just the concrete.
- Caps installed on chimneys that were never meant to have them. A gas-fired furnace conversion leaves a flue that’s too big for the new exhaust, and a cap that traps condensation instead of venting it. We see this constantly in Wyandanch as PSEG Long Island’s gas lines expand and oil burners get converted.

FAQs - Chimney Cap & Crown in Wyandanch
Because Wyandanch’s housing stock came out of the ground in the late 1940s through 1960s, and the concrete crowns and original caps are now sixty to eighty years old. Long Island’s freeze-thaw cycles pound on that aging concrete every year, and nor’easter rain drives straight into whatever cracks have opened. By late fall, the damage is done and the water’s already inside the masonry. We book heavily in October and November for exactly this reason. Call (631) 318-8656 for an estimate before the weather forces the issue.
Not with a single cap that chokes both drafts. The proper fix in Wyandanch’s 1950s Cape Cods is a multi-flue cap that covers the entire chimney top and lets each flue vent independently. That’s the fix we put on the Straight Path job where the old single cap was literally drawing the oil burner’s exhaust into the fireplace. It’s also the fix that keeps rain out without creating negative pressure in one of the flues. If you’ve got a shared flue in Wyandanch, get a camera inspection before anyone quotes a cap. We include that footage in every estimate. Call (631) 318-8656.
Usually because the repair didn’t include a proper drip edge, or because the crown wasn’t mixed with the right ratio for freeze-thaw durability, or because the underlying masonry is still moving from decades of water absorption. In Wyandanch, where the brick is often soft from forty years of coastal humidity, a crown that’s poured without addressing the spalled brick underneath is a crown that’s going to crack again. We rebuild the masonry as part of the crown job, not as an add-on. That’s the only way it holds.
Usually a stainless steel or copper single-flue cap sized to the actual flue opening, installed with a proper chase cover anchoring it to the crown. On Wyandanch’s Capes, the flue is often oversized for what’s currently venting through it, so the cap needs to allow enough draft while keeping out rain and animals. Wendell will look at the flue, the liner condition, and what’s venting through it before recommending anything. You’ll get a specific recommendation with a price, not a wall of options. Call (631) 318-8656 to schedule.
A cracked crown lets water into the flue, and water is what turns loose creosote into a hard, glazed third-degree deposit that’s far harder to remove. So a proper crown with a drip edge keeps the flue dry, keeps the creosote in its easier-to-remove first-degree state, and extends the safe interval between cleanings. In Wyandanch’s post-war Capes where fireplaces get regular use, a dry flue is the difference between a brush job and a chemical or mechanical removal. The crown isn’t just concrete. It’s the first line of defense for the entire venting system.
The Shared-Flue Problem in Wyandanch
Here’s something that shows up more here than in Deer Park or North Babylon. Wyandanch’s post-WWII Cape Cods and ranch homes, built fast in the late ’40s and ’50s to house returning veterans, often share a single flue between an oil-fired furnace and a wood-burning fireplace. That layout was common among the tract builders. It’s also a code violation under current Suffolk County and NYS fire code.
Why does that matter for cap and crown work? Because when you add a cracked crown or a missing cap to a shared flue, you’re not just letting rain in. You’re letting rain mix with oil soot from the furnace and creosote from the fireplace, creating a paste that blocks the flue and back-vents carbon monoxide into the house. The fix isn’t always a full reline. Sometimes it’s as simple as a properly built crown and a correctly sized multi-flue cap that gives each appliance its own draft path.
We drove out to a 1950s Cape Cod on Straight Path where rain was running straight through a cracked crown and into the shared flue. Our crew removed the spalled concrete crown, rebuilt it with a proper drip edge, and installed a Gelco multi-flue cap so both the oil burner and the fireplace draft safely without pulling each other’s exhaust. That’s the kind of job we do in Wyandanch on a regular basis.
What a Cap and Crown Job Actually Costs You
The honest answer: if your crown is cracked but the masonry is solid, you’re looking at a $450 to $1,100 repair. If the brick has spalled and the crown needs a full rebuild, it’s $1,200 to $1,900. A standard cap install runs $285 to $425. A multi-flue cap for a shared chimney runs $650 to $1,400. A custom cap for an odd-sized flue starts at $500.
What affects the price: access (single-story ranch vs. two-story chimney), the condition of the underlying masonry, whether the existing crown needs full removal or can be coated, and the flue size. You’ll always get a flat-price quote before we start. No hourly billing, no surprises when the invoice arrives. Call (631) 318-8656 for an exact number on your house.
