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.
Fast, Reliable Chimney Cap & Crown Across Barnum Island
If your chimney cap is rusting through or your crown is cracking, you already know the problem. What you may not know is that on Barnum Island, both fail faster than almost anywhere else in Nassau County. The salt air off Reynolds Channel eats galvanized steel in five to seven years, and once the cap goes, the crown follows. A proper repair or replacement here means using materials that can actually hold up to coastal conditions. This page covers what fails, what it costs, and what will actually last. Call (631) 378-3317 for a straight answer about your chimney, no runaround.

Our Chimney Cap & Crown Services in Barnum Island
We focus on the three jobs that matter most on this island: replacing corroded caps, repairing cracked and spalled crowns, and building custom caps when standard sizes won’t do. Here’s what each involves on a Barnum Island chimney.
Cap Replacement
Most Barnum Island caps are galvanized steel, and galvanized doesn’t last here. Salt air rusts the corners and fastener holes within five to seven years. Once that happens, rain and salt spray pour straight down into the flue. We remove the old cap, inspect the flue tile beneath it, and install a replacement that will actually hold up: stainless steel for standard flues, or a custom cap from Copperfield if your flue size is unusual. On a 1950s Cape on Admiralty Boulevard, we pulled a galvanized cap that had rusted through at the corners after six years of channel air. The crown underneath was soft enough to crumble under a thumb.

Custom Cap
Pre-fabricated caps don’t always fit a 60-year-old chimney. Barnum Island’s post-war Capes and ranches often have square terra-cotta flues in odd dimensions. When a standard cap leaves gaps or sits loose, we build a custom stainless cap cut to the exact flue dimensions. That means no wind-rattle, no gaps for rain to sneak through, and no fasteners that work loose in a nor’easter.

Crown Repair
The crown is the concrete slab that seals the top course of brick. On Barnum Island, years of salt crystallization pressure crack and spall those crowns faster than on the mainland. Once a crown opens up, water travels down through the smoke chamber and firebox. We rebuild crowns with a Portland-based mix that sheds water properly, with an overhang so runoff drips away from the brick instead of down the face of the chimney. We also recoat crowns that are still structurally sound but have hairline cracking starting.

Crown Coating
If your crown is intact but the surface shows spider-cracking, a flexible crown coat can buy years of extra life. We use products from Gelco and Olympia Chimney, applied in a thick layer that flexes with the chimney instead of cracking like old-fashioned concrete patch. For a Barnum Island chimney, this is often the difference between a $400 repair now and a full crown rebuild in two years.

Common Chimney Cap & Crown Problems We See in Barnum Island Homes
- Rusted-out galvanized caps. Five to seven years near Reynolds Channel is about all a standard galvanized cap gets. The corners and fastener holes rust through first, and from there the cap stops shedding water and starts channeling it in.
- Cracked and spalled crowns. Salt crystallization works its way into the concrete, freezing in winter and expanding in summer. Most crowns we see on the island have hairline cracks by year eight, and open spalling by year ten.
- Post-Sandy damage hidden under the cap. Many chimneys on the island sat under storm-surge saltwater in 2012. The brick directly under the cap is often the worst, with efflorescence staining and spalled faces that don’t show until the cap comes off.
- Detached caps after nor’easters. We see caps that have shifted or blown completely off in winter storms. It’s almost always the same story: the top course of brick was softened by salt water, the fasteners lost their grip, and a north wind did the rest.

FAQs - Chimney Cap & Crown in Barnum Island
Because Barnum Island sits entirely surrounded by Reynolds Channel, every chimney gets constant salt-laden air that rusts a standard galvanized cap in five to seven years, roughly half the lifespan you’d see just two miles inland in Oceanside. The salt doesn’t just sit on the surface, it works into the fastener holes and under the edges, and once water gets a path through, the cap is done. Stainless steel is the fix. Call (631) 378-3317 for a look at yours.
Sandy put much of Barnum Island under saltwater, and brick that absorbed that water has been slowly shedding salt ever since. We regularly pull off a cap and find efflorescence-stained brick and spalled top courses that look fine from the ground. The salt breaks the bond between mortar and brick, and the cap assembly loosens, which is why we see more detached caps here than in surrounding communities. A close inspection of the top course is the only way to know if yours is affected.
Usually we can replace just the cap, but we won’t know until the old one comes off. The crown is directly underneath it, and on Barnum Island we frequently find the crown cracked or spalled at the same time. If the crown is intact, a cap replacement is straightforward. If it’s compromised, a new cap over a broken crown just hides the problem and lets water keep moving in. We’ll show you camera footage and tell you plainly what you do and don’t need to fix now.
Stainless steel, period. A galvanized cap near Reynolds Channel will rust through in five to seven years. A stainless cap from a maker like Copperfield will last decades. There’s no judgment if budget matters, we’ll quote both. But we tell every Barnum Island customer the same thing: the cheaper cap is not the cheaper cap when you’re paying for it twice.
Every year, once a year, burn or no burn. Chimneys break in the off-season too, and on an island this close to the water, a small crack can open into a serious problem in one winter. We recommend an annual visual inspection of the cap, crown, and top course of brick. It’s a short visit, and it catches things early. First-degree creosote is a brush job. Third-degree is a glaze, and it’s a different conversation. If it’s been a while, call (631) 378-3317 and we’ll get you on the schedule.
Top Hat Chimney serves all of Barnum Island, from the houses along Admiralty Boulevard to the side streets off Broadway. We know the housing stock: 50- to 70-year-old Capes and ranches with original masonry chimneys, many of which have been through Sandy and decades of salt air. We’ll give you a straight answer about your cap and crown, not a upsell. Backed by the 90-Day Done Right Promise, in writing, on every job. Call (631) 378-3317 for a free estimate.
