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.

AfterFast, Reliable Chimney Cap & Crown Across Williston Park
A chimney cap replacement in Williston Park typically runs $350-$650 for a standard single-flue stainless cap, while crown repair or rebuild work lands between $600 and $1,400 depending on how far the original mortar has spalled. We’re in Williston Park most weeks, and Wendell knows the difference between a crown that just needs coating and one that needs new forms poured before the next nor’easter hits. If you live near Willis Avenue or over by the LIRR cut, call (516) 963-1068 and we’ll schedule a camera inspection with a straight answer on what actually needs doing.
This page is about the specific cap and crown problems we see on the village’s 1920s through 1950s homes. Not general chimney advice. The real thing.
Why Top Hat Chimney Is Williston Park’s Preferred Chimney Cap & Crown Company
Most of our Williston Park calls start the same way. A homeowner notices a rusted cap, or water staining on a bedroom ceiling near the chase, or a neighbor mentions they had their crown rebuilt last year. Then they call a national outfit, get a quote over the phone, and a stranger shows up with a different number. We hear this every month.
Wendell Pike founded Top Hat Chimney in 1999, and he still answers the phone. When our Chimney Cap & Crown team schedules a Williston Park visit, the price you get on the call is the price on the invoice, before a single tool comes off the truck. You’ll see his name and license number on every job. And the 90-Day Done Right Promise is in writing on every ticket: if it’s not right, one call brings him back. That’s not marketing. That’s just how he’s run things for over 29 years.
Williston Park is its own place. Less than half a square mile, fully built out before most of Nassau County sprawled. We don’t treat it like a stop on a route. We treat it like a neighborhood where we keep running into the same houses, and the same homeowners at the deli on Hillside Avenue.
Our Chimney Cap & Crown Services in Williston Park
Cap Installation
Most original caps on Williston Park chimneys either rusted out years ago or were never installed in the first place. Coal-era flues were left open, and when furnaces converted to oil, nobody added a proper rain cap. We install stainless steel and copper caps sized to the actual flue dimensions, not whatever’s on the truck. A cap keeps rain off the crown and keeps birds, squirrels, and leaves out of the flue. For Williston Park’s older single-chase chimneys with two flues sharing one stack, that sizing matters more than anywhere else we work.
Cap Replacement
If your existing cap is rusted through, bent from storm debris, or so corroded from Long Island Sound salt air that it’s no longer shedding rain, replacement is usually the cheaper fix than patching. We’ll remove the old cap, measure both the flue tile and the chase dimensions, and install a replacement from Olympia Chimney or Copperfield that’s matched to the actual draw of your fireplace or boiler. We don’t sell caps off a rack.
Crown Repair
This is the big one in Williston Park. The original crowns on these 1920s-1950s chimneys were poured from Portland cement-based mortar that’s now spalling at an even rate across the village. A crown with open cracks lets water into the brick below, and that water freezes, and the freeze-thaw cycle from nor’easter season does the rest. We grind back the failed mortar, inspect the flue condition underneath, and rebuild the crown with proper overhang and a drip edge so water sheds away from the brick. No crown repair goes forward without camera footage you can watch.
Crown Coating
If the crown is still structurally sound but porous or hairline-cracked, coating is the right call and we’ll say so plainly. A brush-applied elastomeric coating seals the surface against water absorption and buys years before a full rebuild. For Williston Park chimneys with two flues in one chase, we coat the entire crown and apron in one pass so water can’t find a seam. We use Gelco and Olympia Chimney crown repair products, and we’ll show you why a coating is or isn’t enough before you spend anything.
Multi-Flue Cap
Plenty of Williston Park homes have one brick chase carrying two flues side by side, usually a fireplace and an oil boiler. Capping both flues separately on a shared crown often leaves gaps where the caps meet. A custom multi-flue cap from Copperfield spans the entire chase and covers both flues under one lid, with a continuous drip edge that protects the crown between them. We measure the full chase, not just each flue opening, and order from the manufacturer’s spec sheet.
Custom Cap
When the chase is an odd size, or the crown is shaped around a Tudor-style corbel detail, an off-the-shelf cap won’t sit right. We measure and order custom caps from Copperfield or Famco, in stainless or copper, matched to the existing brick color and the home’s roofline. This is more common in Williston Park than in newer subdivisions, simply because these pre-war chases were built by hand and no two are identical.

Trusted Brands We Service in Williston Park
We install and service caps, crowns, and liners from Olympia Chimney, Copperfield, and Famco, and we keep the common sizes and replacement parts on hand for Williston Park’s older flue dimensions. That means a cap replacement on a 1930s Tudor doesn’t wait on a parts order from a warehouse. Wendell and his crew work with DuraFlex liners as well when a crown rebuild reveals a damaged flue that needs relining. You’ll know exactly what brand and part number is going on your chimney before it goes on, because the estimate lists it.
Common Chimney Cap & Crown Problems We See in Williston Park Homes
- Salt-air crown spalling: The village sits close enough to the Long Island Sound that salt-laden air coats chimney tops year-round. Original Portland-cement crowns from the 1920s-1950s absorb moisture, and the salt accelerates mortar erosion faster than you’ll see in Mineola or Garden City. The result is a crown that crumbles at the edges and exposes the flue to direct rain.
- Open coal-era flues with no cap: Many Williston Park chimneys were built for coal and never got a proper cap when the home switched to oil. Rain falls straight into the flue, soaks the accumulated soot, and creates an acidic slurry that eats the mortar joints from the inside. A crown can fail underneath a perfectly good cap if the flue was never sealed.
- Two flues, one chase, shared damage: When one flue’s crown section fails and drops debris into the shared chase, the blockage can push exhaust back down the adjacent flue. We’ve pulled fallen brick and mortar from between side-by-side flues on more than one Williston Park chimney. Both flues need camera inspection together before either is cleaned or capped.
- Rusted uncoated steel caps: The older steel caps on Williston Park chimneys are often the cheapest thing a previous owner could find. Salt air plus nor’easter rain strips the coating in a few seasons, and the rust runs down the brick, staining the chase. A stainless or copper replacement ends the cycle.
Pricing for Chimney Cap & Crown in Williston Park, NY
Here’s the honest number range for Williston Park work, as of this writing. Standard single-flue stainless cap installation: $350-$650. Multi-flue custom cap spanning a shared chase: $500-$900, depending on chase width and cap material. Crown repair with grinding and new mortar: $600-$1,100. Full crown rebuild with new forms and proper overhang: $1,000-$1,400. Crown coating over a sound crown: $350-$600. These assume normal access from a ladder or roof. A chimney on a steeply pitched Tudor roof may add setup time. Every estimate is free, it’s the number you get before work starts, and it’s backed by the 90-Day Done Right Promise. Call (516) 963-1068 for an exact quote on your chimney.
Why Williston Park’s Older Chimneys Fail the Same Way
Williston Park is a tiny, fully built-out Nassau County village developed almost entirely between the 1920s and 1950s. That means nearly the entire housing stock, the Capes and the Tudors and the Colonials off Hillside Avenue and around the village center, shares chimneys of the same aging generation. Original masonry flues built for coal, later pressed into service for oil burners without proper clay-tile relining. Original crowns poured from the same Portland cement. Original caps, when they exist at all, rusted through around the same decade.
The local truth is this: your neighbor’s crown is spalling at the same rate as yours. When we work on a chimney on one side of the LIRR tracks, we already know what’s likely happening on the other side two streets over. That’s not a sales pitch. It’s just what 29 years of repeating the same pattern looks like.
We capped two adjacent brick chases on a 1930s Tudor off Willis Avenue last winter. Both original clay-tile crowns had spalled down to the flue openings, and our camera showed first-degree creosote already glazing the fireplace flue where rain had washed soot. Our crew ground back the crowns, built new forms with Olympia Chimney’s crown repair mortar, and installed custom Copperfield multi-flue caps over each chase. The homeowner watched the entire inspection feed in real time before approving a single part. That’s how every Williston Park job should go. Camera footage and a plain-English verdict. No exceptions.

FAQs - Chimney Cap & Crown in Williston Park
Because Williston Park sits close enough to the Long Island Sound that salt-laden air settles directly on exposed chimney tops, and the village’s housing stock was built in one concentrated wave from the 1920s through the 1950s using the same original Portland-cement mortar. Garden City and Mineola have some newer construction and more variety in masonry work. Here, the crowns are all aging on the same clock, and the salt air speeds up the spalling. If your neighbors are rebuilding crowns, yours is likely next. Call (516) 963-1068 and we’ll camera-inspect it before it opens up.
Yes, in most Williston Park cases. A properly rebuilt crown with a coated surface lasts significantly longer in this salt-exposed climate than bare mortar. The coating fills the microscopic pores that let water in during freeze-thaw cycles. We coat every crown we rebuild unless the homeowner specifically declines, and we’ll show you why on the inspection video. It’s the cheapest insurance on a chimney you’ll ever buy.
For a single brick chase carrying two flues, a multi-flue cap is usually the better fix in Williston Park. Two separate caps on a shared crown leave a gap between them where rain, debris, and snow can sit directly on the crown. A custom Copperfield multi-flue cap spans the full chase and protects the crown between the flues. We’ll measure the actual chase and give you the straight comparison before you choose. Call (516) 963-1068 for a free measurement.
Repointing fixes the mortar joints between bricks. It does not fix a crown that has spalled down to the flue opening. On Williston Park’s original chimneys, the crown is a separate cement slab poured over the top course of brick, and when it crumbles, water runs down the inside of the chase, not just the outside face. We’ll camera-inspect and tell you plainly whether repointing alone is enough. If the crown is sound, we’ll say so. If it’s not, we’ll show you the footage.
If your cap was installed by a previous owner without measuring, there’s a good chance it’s wrong. A cap that’s too small doesn’t fully cover the flue opening, letting rain in around the edges. A cap that’s too large can sit crooked on the crown and pool water. We measure both the flue tile dimensions and the crown surface before recommending a cap. On Williston Park’s older shared-chase chimneys, the flue openings are often non-standard sizes, and a custom cap is the only correct fit. Call (516) 963-1068 and we’ll measure it for free.
