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 Brentwood’s Preferred Chimney Cap & Crown Company
Wendell Pike founded Top Hat Chimney in 1999 and has been crawling across Long Island rooftops ever since. He’s not a franchise that rotated in last spring and won’t be here next fall. He’s the guy who answers the phone at 2 a.m. and the guy you might run into at the hardware store on Saturday. When you call for Chimney Cap & Crown work, you get a straight answer about what’s broken, what it costs, and whether it can wait. No bait pricing. No surprise add-ons at the door.
We serve Brentwood regularly and know the housing stock here: post-WWII Cape Cods and ranches with single-wythe brick chimneys that are now 50 to 70 years old. Those chimneys have original clay tile liners and crowns that were poured with a mortar mix never meant to survive six decades of Long Island freeze-thaw cycles. We’re familiar with the specific failure patterns on these homes, which means we diagnose faster and don’t sell work you don’t need. If your crown is fine and your cap just needs re-anchoring, that’s what we’ll tell you.
Our Chimney Cap & Crown Services in Brentwood
Cap Replacement
A galvanized cap on a 1960s Brentwood chimney has usually rusted through at the seams after four or five decades of nor’easter-driven salt air. We pull the old cap, inspect the flue tile beneath, and install a stainless steel replacement sized for your flue. Stainless stands up to Brentwood’s coastal winds far longer than galvanized. On homes along Crooked Hill Road and Washington Avenue where wind exposure is constant, we recommend caps with reinforced mounting brackets, not the cheap slip-in type.
Cap Installation
Plenty of Brentwood chimneys never had a proper cap installed at all, especially on ranches where the original builder saved thirty dollars in 1962. You’ll know because birds get in, rain comes down in heavy storms, and you can hear wind whistling through the firebox. We install correctly sized caps from Olympia Chimney and Famco, anchored to the flue tile with mechanical fasteners so a nor’easter won’t send it end over end into your neighbor’s yard. A cap also keeps squirrels and raccoons out, which matters in Brentwood’s older neighborhoods where mature trees sit close to the roofline.
Crown Repair
This is the bread-and-butter job on Brentwood homes. The crown is the concrete slab that caps the top of the chimney and slopes water away from the flue. On 1950s-1970s chimneys, that slab was often poured with a thin mortar wash that has cracked into pieces. Once water gets into those cracks and freezes inland of Great South Bay, the crown spalls apart. Hairline cracks grow to quarter-inch gaps in one winter. We rebuild crowns with a proper sloped form, overhang, and drip edge so water sheds away from the brickwork instead of running down it.
Crown Coating
When a crown is still structurally sound but shows hairline cracking, a crown coating buys you years without a full rebuild. We use Gelco CrownCoat, a flexible waterproof coating that bridges small cracks and resists the expansion and contraction Brentwood sees every winter. It’s an honest fix for the right crown. If your crown is already crumbled or pulling away from the flue, we’ll tell you coating would be a waste of money and you need a rebuild instead. Some companies will coat anything. We won’t.

Trusted Brands We Service in Brentwood
We install and service products from Olympia Chimney, Gelco, Famco, and HeatShield. These are brands we’ve worked with for years and stand behind. If you have an existing cap or crown system from one of these manufacturers, we can often match it exactly rather than rigging up something generic. Because we work in Brentwood week in and week out, we keep the common sizes and mounting hardware in the truck, which means less waiting on parts and fewer return trips. You won’t get the “we have to order it” runaround for standard cap replacements.
Common Chimney Cap & Crown Problems We See in Brentwood Homes
- Rust-through on galvanized caps. Wind-driven salt air from nor’easters catches the lip of the cap and eats through the galvanized coating in a few seasons. You’ll see rust streaks running down the brick or the cap flapping loose in a storm.
- Freeze-thaw crown cracking. Brentwood sits 8-10 miles inland from Great South Bay, so we log more hard freeze nights than coastal hamlets. Water pools in hairline crown cracks, freezes, and splits the slab. Repeat that thirty times a winter and the crown looks like a cracked sidewalk.
- Efflorescence streaking down the brick. White chalky streaks on the exterior chimney are a tell on Brentwood’s oil-to-gas conversion homes. The oversized flue condenses moisture against the old clay tile, and that moisture pushes salts through the brick. It’s a sign the crown coating has failed and the liner is undersized.
- Anchor pull-out after nor’easters. Caps held on with a friction fit or small screws get lifted clean off by wind gusts over open ground. Brentwood has less tree cover than northern Suffolk, so the wind hits chimneys harder. We see missing caps all over the hamlet after every big coastal storm.
Pricing for Chimney Cap & Crown in Brentwood, NY
A standard stainless cap replacement on a single-flue Brentwood chimney runs $325-$525 installed. Multi-flue caps run higher, typically $550-$875, because of the larger footprint and mounting hardware. Crown repair with a partial rebuild runs $400-$650. A full crown rebuild with proper form work, overhang, and drip edge is $700-$1,100 depending on chimney size and access. Crown coating alone is $250-$400 when the crown is still sound. Staging or steep roof pitch adds to the cost. Every estimate is free, no trip charge inside the county, and the number we quote is the number you pay. We also knock $40 off any repair over $200 and always give 10% off to seniors and veterans. Call (516) 968-5380 for a straight quote.

FAQs - Chimney Cap & Crown in Brentwood
Brentwood sits 8-10 miles inland from Great South Bay, which means it loses the thermal buffering that keeps Bay Shore and other waterfront hamlets above freezing on more winter nights. Every time the temperature crosses 32 degrees, water in hairline crown cracks expands about 9% and pushes the crack wider. Brentwood logs more of those freeze-thaw crossings per winter than the immediate coast, so crowns here fail faster. Call (516) 968-5380 if you’re seeing cracks wider than a credit card.
A stainless steel cap with mechanically anchored brackets holds up best. Galvanized caps rust through at the seams from salt air, and friction-fit caps get blown off in nor’easters. On Ridge Avenue we replaced a spalled crown on a 1963 brick ranch where the original galvanized cap had pulled its anchors loose during a storm. The fix was a stainless Olympia Chimney multi-flue cap rated for wind-driven rain, plus a rebuilt crown with a proper overhang and Gelco CrownCoat waterproofing. That combination should outlast the next owner.
It’s usually both, plus a liner complication. The white streaks are efflorescence, salts pushed out of the brick by moisture. On Brentwood’s oil-to-gas conversions, the old oil-era flue is oversized for a gas appliance, so warm moist exhaust condenses against the clay tile and drives water through the masonry. A cracked crown coating lets in more water from the top, making the streaking worse. We can assess whether a crown coating and a properly sized liner fixes it, or whether the cap alone is the culprit. Either way, you’ll see camera footage before we recommend anything. Call (516) 968-5380 for a free inspection.
Every two years is the honest answer for Brentwood, more often if you’re near open ground where nor’easter winds hit hard or if your chimney is over 30 years old. That matches the inspection interval for mortar joints and flashing. Once a year, burn or no burn. A cracked crown gets dramatically more expensive to fix if it’s ignored for a decade. We inspect caps and crowns as part of a standard sweep visit.
Yes, if the crown is still sound with only hairline cracks, which is common on well-built 1960s chimneys where the original pour was thick and the slope was decent. A Gelco CrownCoat application bridges those small cracks and flexes through the freeze-thaw cycles that Brentwood gets inland from the Bay. If the crown is already spalled, crumbled, or pulling away from the flue tile, coating won’t help and we’ll tell you that directly. The camera footage and a plain-English verdict, every time, no exceptions.
If water is getting into your Brentwood chimney, don’t wait for another winter to make the crack wider. Call Top Hat Chimney at (516) 968-5380 for a free cap and crown estimate.
