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.

AfterTrusted Chimney Cap & Crown for Long Island Homeowners
Chimney cap and crown work in Long Island typically runs $300 to $1,400 depending on whether you need a simple cap replacement or a full concrete crown rebuild, and most jobs are completed in a single visit. A cracked crown or missing cap is not a cosmetic issue. It is the number one way water gets into your flue and starts quietly tearing up your chimney from the inside. Wendell Pike has been setting caps and repairing crowns across home territory since 1999, over 29 years of climbing Long Island roofs in every season this island can throw at a house.

What Our Chimney Cap & Crown Service Includes
Cap Installation
A chimney cap is the roof over your flue. It stops rain, snow, leaves, and animals from going down the opening while still letting smoke and gases escape. On Long Island, where coastal storms can push rain sideways and oak leaves are relentless in the fall, an uncapped flue is an open invitation for water damage and squirrel nests. In areas like our Chimney Cap & Crown in Oceanside territory, this is especially common. Wendell and his crew measure the flue, match the cap to the exact inside and outside dimensions, and fasten it to the flue tile or chase cover so it stays put in nor’easter winds.
Cap Replacement
If your existing cap is rusted through, bent from a falling branch, or the mesh is torn wide enough for a starling to squeeze through, it is time for a replacement. A cap that no longer fits tightly or has rusted to the point of crumbling is doing nothing for your chimney. We remove the old one, inspect the flue underneath for hidden damage, and install a new cap sized correctly for your flue, not a generic one-size-fits-most discount from a big-box store.
Crown Repair
The crown is the concrete slab at the very top of the chimney that seals the masonry from the flue liner to the outside edge. In Long Island’s freeze-thaw cycle, small cracks in a crown become bigger cracks every winter. Water seeps in, freezes, expands, and spalls the concrete. We grind out the damaged material, fill and seal the cracks with a weatherproof crown sealant, and correct the slope so water runs off instead of pooling. A proper crown has drip edges and slopes away from the flue, and we make sure yours does.
Crown Coating
When a crown is still structurally sound but the surface is porous and starting to absorb water, a crown coating is the smart fix. We apply a flexible, waterproof membrane that bonds to the existing concrete and flexes with temperature changes instead of cracking. In neighborhoods from Hempstead to our Chimney Cap & Crown in Freeport service area, we regularly see crowns that look fine from the ground but soak up water like a sponge. Sealing them before the cracks start saves homeowners a full rebuild down the line.
Multi-Flue Cap
Homes with two or more flues sharing one chimney often need a single multi-flue cap that covers the entire chase top. This style sits on the chimney crown and spans all the flues, which means the crown itself has to be in good shape to support it. We measure the full outside dimensions, check that the crown can bear the load, and use a cap with the right mesh size to keep out the raccoons and chimney swifts that find Long Island attics and flues so inviting.
Custom Cap
Odd-sized flues, older masons who built chimneys to their own liking, or chimneys with unusual cap dimensions sometimes need a custom solution. We work with manufacturers like Copperfield to build caps to spec, in stainless steel or copper, cut to fit your exact flue dimensions. If you have a historic home in Rockville Centre or a mid-century build in Levittown with nonstandard flue tiles, our Chimney Cap & Crown in Rockville Centre team can build a custom cap that actually fits and seals correctly. Wendell will show you the measurements and explain what is being built and why.

Brands We Service for Chimney Cap & Crown
We install and service Copperfield caps regularly, and we stock their most common sizes on the truck. Copperfield builds a well-engineered stainless steel and copper cap, and we have put enough of them on Long Island chimneys to know exactly how they behave in coastal salt air and how they hold their fasteners through a winter of freeze and thaw.
For crowns and waterproofing we use Gelco sealants and crown coating systems because they hold up to the specific abuse a Long Island chimney takes: wet, windy winters and hot, humid summers. We also work with DuraFlex products when a crown job turns into a liner conversation, which happens more often than people expect. Whether your chimney has a Copperfield cap on it right now, a cheap box-store special, or nothing at all, we can set it up correctly. If you have any other make, Wendell’s 29 years means he has probably seen it and knows what fits.
Signs You Need Chimney Cap & Crown Right Now
- Water stains on the ceiling near the chimney. This is the classic sign that water is getting past the crown or cap and running down the interior of the chimney. By the time the stain shows on drywall, the crown has usually been failing for a year or more. The fix is still cheaper now than after the flue liner rots out.
- Pieces of concrete or mortar on the roof or in the yard. A crown that is spalling is breaking apart in chunks, and every chunk that falls off is one more entry point for water. If you see crumbling concrete at the base of the chimney, the crown is actively failing and will not heal on its own.
- Birds, bats, or squirrels in the flue or fireplace. An uncapped or torn cap lets animals in. A squirrel can do an astonishing amount of damage in a flue in a single season, and the nest debris is a chimney fire waiting for a match. Long Island has plenty of raccoons, gray squirrels, and chimney swifts looking for a dry place to set up house.
- You can see daylight through cracks in the crown when looking down from an upper window. Any crack wider than a hairline is a problem, and it only gets wider. Long Island winters guarantee the water in those cracks will freeze and expand. Sealing or rebuilding the crown before next winter is the difference between a coating job and a full masonry rebuild.
- Rust stains running down the chimney or a cap that looks like it belongs in a scrap yard. A rusted steel cap is no longer keeping water out, and rust from the cap is staining your masonry as it runs down. Stainless steel or copper replacements handle the salt and weather out here far better than the galvanized steel caps that came with many older homes.

Wendell or a member of his crew shows up in uniform, on time, and takes a look. We inspect the cap, the crown, the flue tile, and the flashing from the roof. We do not touch a thing until we have looked and measured. The price is agreed on before any work starts, and the number does not move unless we find something and you approve it first.
- 3
We show you what we’re seeing. When a Chimney Cap & Crown in Long Island inspection involves something hidden, we bring a camera. The footage and a plain-English verdict, every time, no exceptions. If a crown repair is all you need, we will say so. If you need a liner and we see it on camera, you will see it too before you spend a dollar.

How Much Does Chimney Cap & Crown Cost in Long Island?
A standard stainless steel cap installation or replacement in Long Island typically runs $300 to $650, including materials and labor. A custom cap or copper cap can push that to $700 to $1,100. Crown repair with crack sealing and waterproof coating generally falls between $400 and $900 depending on the size of the crown and how much grinding is needed. A full concrete crown rebuild, where the old crown is removed and a new one is formed with proper slope and drip edges, starts around $1,200 and can go to $2,500 for large or multi-flue chimneys. For a detailed breakdown, see our Chimney Cap & Crown cost guide.
What affects the price most is access. A chimney on a steep Long Island roofline in Dix Hills or Smithtown takes more time, more safety gear, and more care than a low-slope roof in Seaford. A multi-flue chimney costs more than a single flue. Masonry repair needed under the crown, like rechinking or part of the flue tile that fractured, adds to the total. The best way to avoid overpaying is to get a real inspection with eyes on the actual chimney, not a phone quote based on a guess. Every estimate from Top Hat Chimney is free, includes camera proof where needed, and stands as the final price. There is no trip charge inside our service county, $40 off any repair over $200, and a 10% discount for seniors and veterans, always. Call (516) 968-5380 for an exact quote.

Frequently Asked Questions - Chimney Cap & Crown in Long Island
A chimney cap is the metal cover over the top of the flue, and the crown is the concrete slab that seals the top of the masonry chimney around the flue. The cap keeps rain, animals, and debris out of the flue, while the crown sheds water off the masonry so it does not soak into the brick and mortar. Both need to be in good shape for the chimney to survive Long Island weather.
Most cap installations and replacements are done in under two hours from setup to cleanup. Crown repairs take longer, usually three to five hours depending on how much grinding and sealing is required. A full concrete crown rebuild is generally a single-day job, and we tell you the timeline before we start so there are no surprises.
You will typically pay $300 to $650 for a cap installation or replacement, $400 to $900 for crown repair and sealing, and $1,200 to $2,500 for a complete concrete crown rebuild. The exact price depends on flue size, roof pitch, whether the chimney has multiple flues, and whether hidden masonry damage is found. Every estimate is free, with a fixed price agreed before work begins. Call (516) 968-5380 for an exact quote.

You do not need to be home for the whole job, but Wendell likes to walk through the findings with you before leaving whenever possible.
