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.

Our Chimney Cap & Crown Services in North Bay Shore
Cap Replacement
Galvanized caps on North Bay Shore chimneys fail fast. We replace them with stainless steel so they don’t need replacing again in five years. Cap replacement typically runs $425 to $950 in this market depending on flue size and roof access.

Crown Coating
The crown is the concrete slab that seals the top of the chimney, and on 1950s Cape Cods throughout North Bay Shore it’s original and cracked. We coat crowns with Gelco, a waterproof membrane that handles freeze-thaw cycles without delaminating. Crown coating in North Bay Shore generally costs $350 to $700, and it’s the single best dollar-on-dollar repair for coastal chimneys.

Crown Repair
When the crown has spalled beyond what coating can save, we rebuild it with the proper slope and a drip edge so water sheds away from the flue instead of running down the brick. Crown repair in North Bay Shore usually falls between $700 and $1,500 depending on how much demolition is required. Most 1950s-era crowns can be saved with coating, but we’ll tell you plainly when the concrete has gone too far.

Cap Installation
Homes in North Bay Shore that never had a cap are common. And they’re the ones with rain, birds, and leaves in the smoke chamber. Installation of a new stainless or copper cap runs $390 to $850 for standard sizes. Multi-flue and custom caps run higher.

Trusted Brands We Service in North Bay Shore
We install and service caps, crowns, chasing components, and flue components from DuraFlex, Copperfield, and Gelco, and we keep commonly needed parts stocked so North Bay Shore jobs don’t wait on shipping. Copperfield caps in particular hold up better than anything we’ve found for chimneys sitting in salt air off the Great South Bay. If your existing cap is a brand we don’t carry, we can usually source it or replace it with an equivalent that will outlast it. No one should have to wait two weeks for a cap while the freeze-thaw cycle is eating their crown.
Common Chimney Cap & Crown Problems We See in North Bay Shore Homes
- Salt corrosion on galvanized caps. Bay air settles on the metal, eats the seams and screens within five to seven years, and then the screen crumbles down into the flue and blocks the draft. The first sign is usually a slow fire or a bit of smoke in the room.
- Spalled crown edges on 1950s construction. The original crowns were poured too thin and flat. Coastal moisture soaks in over autumn, then January freezes expand it. The edges let go, and water channels into the smoke chamber where you won’t see the damage until it’s expensive.
- Oil-to-gas conversions that never resized the liner. This is the one we see again and again in North Bay Shore. The old 8-inch flue now vents a small gas furnace, condensing exhaust on the underside of the cap and eating it from the inside out.
- Crown cracks hidden by roof pitch. Many ranches and split-levels in the area have shallow roof angles that make the crown hard to see from the ground. By the time you notice the crack from the yard, water has been getting in for two or three seasons.

FAQs - Chimney Cap & Crown in North Bay Shore
Stainless steel is required by common sense, not by code. Galvanized caps on North Bay Shore chimneys corrode through in five to seven years because of salt-laden air off the Great South Bay, while stainless caps routinely last twenty years or more. The cheaper cap costs more over a decade because you’ll replace it two or three times, plus repair whatever water and creosote damage the failed cap allowed in. Call (631) 318-8656 for an exact quote - estimates are free.
Crowns on 1950s Cape Cods and ranches in North Bay Shore should be inspected every two years at minimum, and annually if the chimney is near the bay side of the hamlet where salt exposure is heavier. The freeze-thaw cycle does most of its damage in a single bad winter, and small cracks can grow to structural problems in eighteen months. Give us a call and we’ll check it while we’re up there.
Yes. When a gas furnace vents into the old oversized oil flue, the exhaust cools too quickly and condenses on the inside walls and the underside of the cap. That acidic condensation eats mortar, crown edges, and cap seams from inside where you can’t see it. On a 1954 ranch off Bay Shore Road, we found a cap rusted through and a crown spalled after exactly that conversion. The fix was a DuraFlex stainless multi-flue cap and a Gelco crown coating, and the draft came back immediately.
The first sign is usually a lazy fire or a faint smoky smell in the house on damp days. Salt air corrodes the mesh screen first, and once the screen crumbles into the flue, draft drops and exhaust lingers. Rust flakes on the roof shingles near the chimney are another early tell. If you’re seeing either, call (631) 318-8656 before freeze-thaw makes the crown crack too.
Yes. Original 1950s crowns in North Bay Shore were poured concrete, and standard sealants fail within a season or two under coastal freeze-thaw. We use Gelco, a membrane that flexes with temperature movement and stays bonded longer than any other coating we’ve tested on bay-side chimneys. It’s the right material for this climate, and it’s what Wendell would put on his own house.
