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 Brentwood
A chimney cap and crown in Brentwood do more than keep rain out. On the Cape Cods and ranches that fill this town, a failed crown or missing cap can send flue gases back into the house. Call Wendell and his crew at (934) 935-3847. We’ve been on Brentwood roofs since before most of these chimneys started showing their age, and we’ll give you an honest read on what needs doing and what can wait.
Why Top Hat Chimney Is Brentwood’s Preferred Chimney Cap & Crown Company
Wendell Pike started Top Hat Chimney in 1999 and never turned it into a franchise. He still answers the phone himself half the time, and he’ll be the one walking your roof line with a camera before anything gets quoted. Brentwood homeowners have called us for years because the price we give on the phone is the price on the invoice, and the work comes with a 90-Day Done Right Promise in writing. If it’s not right, one call brings us back.
We know Brentwood’s housing stock. Most of the chimneys we work on here were built between 1955 and 1975, which means clay tile liners, shared flues, and crowns that have taken fifty winters of Long Island freeze-thaw. We’re also local enough to get to any Brentwood street from the Sun Vet Mall area to Wicks Road quickly when a leak shows up after a nor’easter. Your call is answered by a live person, around the clock, and we’ll give you a real arrival window, not a four-hour guess. Seniors and veterans always save 10%, and we never charge a trip fee for calls inside the county.
Our Chimney Cap & Crown Services in Brentwood
This is the difference between a wet chimney and a safe one. On a postwar Brentwood ranch, the crown is the concrete or mortar slab that caps the masonry. The cap is the metal fitting on top of the flue. Both fail here earlier than they should because of the marine air coming off the Great South Bay. Here’s what we do:
Cap Installation
A proper cap keeps rain, leaves, and squirrels out while letting the flue draft. On oil-heated homes in Brentwood, we size the cap for combustion air requirements, not just precipitation. We stock Olympia Chimney and Famco caps in the common Brentwood dimensions, which means no ordering and waiting when yours has rotted through.
Cap Replacement
Rusted caps are the norm around here. Salt-laden humidity off the bay eats galvanized steel in a decade or less. We replace with stainless, and on shared-flue Capes we’ll consider whether a multi-flue cap makes more sense than two singles. If the cap failed early, we’ll also ask why: wind-driven rain, acidic oil soot, or a crown sending water under the flashing.
Crown Repair
Brentwood crowns crack because water gets into mortar joints and freezes. Every winter widens the cracks. We grind back failed crowns, recast the wash slope so water runs off, and seal with Gelco crown coat. This is the job that stops the leak that’s been staining the smoke chamber.
Crown Coating
When a crown is still structurally sound but porous, we coat rather than replace. Gelco and HeatShield products let us seal a hairline-cracked crown on a 1960s chimney and buy it years of service. The camera footage will show you exactly what we saw and what we did. No exceptions.
Multi-Flue Cap & Custom Cap
Many Brentwood Capes have a single chimney serving both the oil burner and a decorative fireplace. Those need either a multi-flue cap sized for both openings or a custom fabrication. We build custom caps for odd brick dimensions and oversized flues. Copperfield and Olympia components cover most of what Brentwood needs.

Trusted Brands We Service in Brentwood
We’re not loyal to one manufacturer. We’re loyal to what lasts in southern Suffolk County air. Famco and Olympia Chimney stainless caps hold up against salt spray better than powder-coated steel ever will. DuraFlex liners go in when an oil flue has been eaten acidic. HeatShield and Gelco give us repair routes that don’t require tearing down the whole chimney. We stock common parts for Brentwood homes so a Tuesday visit converts into a one-day repair, not a three-week wait.
Common Chimney Cap & Crown Problems We See in Brentwood Homes
- Spalled and cracked crowns from fifty winters of freeze-thaw. Marine moisture moves into the mortar. It freezes. It pops the surface. Then rain runs under the flashing and into the smoke chamber. You see it as a water stain on the ceiling.
- Rusted-through caps on oil flues. Acidic, sulfurous condensate from oil combustion eats galvanized steel fast. We see caps in Brentwood with holes you could put a finger through. A little orange-brown staining inside the flue tile is often the first sign.
- Shared-flue Capes with one cap missing. When a single chimney serves the oil burner and a decorative fireplace, a missing cap on the fireplace side lets rain hit a cold flue and drop down into the smoke chamber. The dividing wythe gets wet, and if it’s cracked, flue gases from the oil burner can push into the living space instead of up the flue.
- Wind-driven rain through cheap caps. Brentwood sits flat and exposed. A nor’easter will test a cheap cap in one season. We replace more than a few big-box store caps that looked fine on the shelf and failed on the first storm.

FAQs - Chimney Cap & Crown in Brentwood
Because oil-fired systems produce acidic, sulfurous condensate that corrodes metal caps and eats standard clay liners from the inside, while the marine air off the Great South Bay works the masonry from the outside. Most Brentwood homes have single masonry chimneys from the 1950s-70s, and those crowns have been absorbing freeze-thaw moisture for half a century. It’s not neglect; it’s chemistry and weather. Call (934) 935-3847 and we’ll camera your flue and show you exactly what’s happening.
Salt-laden, high-humidity air accelerates corrosion on metal caps and holds moisture against masonry crowns longer than drier inland air would. Winter freeze-thaw then drives that absorbed water into tiny cracks and widens them. Brentwood sits close enough to the bay that this is a year-round condition, not a coastal-edge exception. Stainless caps and sealed crowns are the practical answer here.
Yes, if it’s sized for the flue diameter and the appliance’s draft requirements. A cap sized too small restricts exhaust; too large lets rain in around the edges. On Brentwood homes with oil heat, we also need to confirm the cap doesn’t trap acidic soot where it can build up against the flue wall. The right cap for an oil flue is a plain stainless model, not a decorative screen that clogs fast.
That staining is the fingerprint of oil soot, and it means the flue has been running wet or acidic for a while. A failed crown lets rain into the flue, and rain mixed with acidic soot makes a corrosive slurry that etches into the clay tile and runs down to the firebox. If you’re seeing orange-brown staining, the crown is usually part of the problem, and we’ll want to camera the whole run before recommending a cap or crown only fix. Call us and we’ll walk through what the camera shows, plain English, no scare talk.
Look at the crown for cracks, spalling, or missing mortar around the flue openings, and check whether both flues have intact caps. On a shared chimney, a cap missing from the fireplace side lets water into the smoke chamber and can wet the dividing wythe. If that wythe is compromised, oil flue gases can push back into the living space. That’s why we treat cap and crown work on shared-flue Brentwood homes as a CO safety call, not just a water call.
