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 Northport

Our Chimney Cap & Crown Services in Northport
Cap Installation
A missing or undersized cap on a Northport chimney is an open invitation to rain, leaves, squirrels, and nesting starlings. We install stainless steel and copper caps sized to the actual flue opening, not whatever is in the truck. On older Northport homes where flues were never standardized, we measure each one. Galvanized caps do not last here. The salt air off the bay eats them in a few seasons, so we push stainless and copper for anyone who wants the job done once.

Cap Replacement
Rusted-out caps are the single most common call we take in Northport between October and April. The old cap rusts through at the seams, the screen tears, and suddenly the flue is wide open to weather and animals. We remove the old cap, check the flue tile under it, and replace with a properly fitted stainless or copper unit. If birds got in, we remove the nest and recommend a cap with a heavier mesh that holds up to Northport’s damp winters.

Crown Repair
Chimney crowns in Northport village take a beating. Century-old masonry crowns were often poured from plain mortar, and salt air works into every hairline crack and spalls it apart over time. We rebuild crowns with CrownSaver, a marine-grade cement system that handles freeze-thaw cycles and salt exposure far better than standard mortar. In attached homes where two properties share a stack, a failed crown on one side compromises the whole structure, so we check the full width of the chimney, not just your half.

Crown Coating
If the crown is still structurally sound but showing surface cracks, a flexible crown coating buys years before a rebuild is necessary. We apply it after cleaning out the cracks and sealing the bond lines. On Northport homes near the water, we recommend re-coating every five to six years. A coated crown beats a cracked crown every time, and the coating is a fraction of the cost of letting water into the flue system.

Multi-Flue Cap
Older Northport houses, especially the attached and semi-detached Victorians, often have two, three, or four flues in a single chimney stack. Separate caps work, but a single multi-flue cap covers the whole crown and can stop water from pooling between flue tiles. On shared stacks where one flue serves each unit, a multi-flue cap also reduces the cross-draft that pulls one neighbor’s exhaust down the other’s inactive flue. We fabricate and install multi-flue caps to fit whatever odd spacing the old masons left us.

Custom Cap
When the flue layout is irregular, or the homeowner wants copper that will weather into a nice patina over the brick, we build a custom cap. Copperfield makes a durable copper cap that holds up to Northport’s marine air, and we have installed enough of them along Bayview Avenue and the harbor side to know how they age. Custom caps are measured on site, fabricated to spec, and installed with a corner-to-corner seal.

Trusted Brands We Service in Northport
We install and service products from Olympia Chimney, Famco, and Copperfield, and we keep common cap and crown materials stocked for Northport jobs so we are not waiting on a warehouse. When a customer needs a specific stainless steel cap or a crown coating that actually handles salt air, we know which product to reach for. If you have an existing cap from one of those brands and it is failing, we can usually match the flue size and replace it same visit.

Common Chimney Cap & Crown Problems We See in Northport Homes
- Salt air corrosion on metal caps. Northport sits right on the bay, and that salt-laden wind eats through galvanized cap seams faster than almost anywhere inland in Suffolk County. A cap that would last fifteen years in Huntington lasts five or six here. We replace more rusted caps near the harbor than anywhere else in our service area.
- Cracked and spalled crowns on century-old brick chimneys. The Victorians and Edwardians in the village were built from the 1880s to the 1910s, and many crowns are original equipment. Lime-based mortar erodes from salt exposure until the crown looks like a crumbling sidewalk. Left alone, water channels behind the flue tile and rots the masonry from inside.
- Shared-stack cross-draft between attached homes. In Northport’s denser older streets, two homes often share one chimney stack with separate flues. A missing cap on the unused flue creates a downdraft that pulls the neighbor’s smoke and carbon monoxide into the other unit. We see this in the row houses off Main Street and the older attached homes near the village center.
- Animal and leaf blockage in uncapped or under-capped flues. Squirrels, raccoons, starlings, and a thick fall leaf pack from Northport’s maples and oaks all find their way into open flues. A proper cap with the right mesh stops all of it. The camera footage and a plain-English verdict after every cleaning show you exactly what was living up there.

FAQs - Chimney Cap & Crown in Northport
Yes, in most cases a properly sized cap on each flue opening, or a well-sealed multi-flue cap across the whole stack, stops the downdraft that pulls exhaust from one unit’s flue into the other. The key is that every flue opening must be capped or sealed, including unused ones. If one flue is open and the neighbor’s fireplace is burning, the pressure difference across the stack draws smoke down the open passage. We fix this regularly on Northport’s attached Victorians. Call (631) 502-3612 and we will camera-check both flues and tell you exactly what is happening inside your shared stack.
Salt air cuts a galvanized cap’s life roughly in half. A standard galvanized cap that lasts twelve to fifteen years inland in Suffolk County may fail in five to seven years on the harbor side of Northport. The chloride in the marine air accelerates rust at the seams and around the mounting brackets. Stainless steel and copper hold up far better, which is why we recommend them for nearly every Northport installation. The camera footage after Northport Chimney Cleaning & Sweep shows you the rust pattern before you have water coming down the flue.
Treat it as a single repair, not two. The crown spans the full width of the shared stack, so patching only your side leaves the neighbor’s half leaking into the same masonry core, and that water migrates behind your flue liner too. We rebuild the entire crown as one job, often coordinating with both property owners to split the cost fairly. Wendell will give both sides a written estimate before any work starts. Call (631) 502-3612 and we will come look at the whole stack, not just your half of it.
For most older Northport homes with a shared stack, yes. A single multi-flue cap covers the whole crown and seals the gaps between flue tiles where water pools and mortar rots. It also smooths the airflow across the top of the stack, which reduces the cross-draft that pushes one neighbor’s exhaust down the other’s flue. Separate caps are fine when the flues are spaced far apart or at different heights, but on the tight multi-flue stacks common in the village, one well-fitted multi-flue cap usually does the job better and lasts longer. We measure and fabricate to the exact flue spacing, because the old masons never used a standard layout.
That is a classic sign of a shared-stack downdraft or a failed flue connection between floors, and in older Northport attached homes we see it constantly. When the living room fireplace is burning, the rising exhaust creates a pressure difference inside the stack. If the second-floor flue is uncapped, the smoke gets pulled down that opening and seeps into the bedroom instead of exhausting out the top. A missing cap, a cracked flue tile between the two levels, or a failed crown letting air in behind the liner can all cause it. Wendell and his crew will camera-inspect the full stack and show you exactly where the leak is. Call (631) 502-3612 for a free estimate and a straight answer.
