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 Bellmore
Custom Cap Installation
Standard caps from the hardware store rarely fit Bellmore’s multi-flue chimneys properly, especially on the 1950s Cape Cods where two flues sit close together under a single wide crown. We measure on-site and fabricate custom stainless caps with welded seams and proper overhang to shed nor’easter rain. A custom cap on a Bellmore home near the creek or bay pays for itself faster than inland because the salt air destroys galvanized steel in three to five years. Stainless lasts.

Cap Replacement
Many Bellmore chimneys still carry the original Famco or builder-grade cap installed when Truman was president. Rusted through, blown loose in a coastal storm, or simply too small to cover the flue properly, these caps let rain straight into the smoke chamber. We remove the old cap, inspect the crown beneath it for hidden spalling, and install a properly sized replacement with correct clearance. On a 1950s Cape off Bellmore Avenue, our tech found the original terra-cotta flue liner stress-cracked and a rusted Famco cap that had been letting nor’easter rain into the smoke chamber, so we pulled the cap, reset the spalled crown, coated it with a flexible crown coating, and installed a custom stainless multi-flue cap over the two flues. Because the homeowner burns a wood stove as primary heat, we also noted heavier creosote on the firebox walls and flagged the flue for a Level 2 inspection before the next season.

Crown Repair
The chimney crown is the concrete slab that seals the top of your masonry chimney. In Bellmore, crowns fail sooner than almost anywhere else in Nassau County. Salt-laden marine air from the bay erodes mortar joints and cracks the chimney crown on 1948-1968 single-wythe brick chimneys faster than inland communities, so water gets behind the flashing and freeze-thaw cycles then pop the brick. Crown repair in Bellmore often means more than a surface patch. We cut out deteriorated concrete, rebuild with proper slope and drip edge, and seal the interface with the flue tile. Done right, and we stand behind it.

Crown Coating
For crowns with hairline cracking but sound structural integrity, we apply a flexible crown coating formulated to bridge small cracks as the chimney expands and contracts through winter freeze-thaw cycles. This is not paint. It is a breathable, elastomeric sealant that stops water infiltration without trapping moisture inside the masonry. On Bellmore’s older chimneys, crown coating is often the most cost-effective path to stop the leak while you plan for full crown replacement. We photograph the crown before and after, and show you exactly what we found.

Multi-Flue Cap Systems
Homes that converted from oil to gas and now burn wood in a fireplace or stove often have two or more flues sharing a single chimney top. A multi-flue cap protects all flues with one properly engineered cover, eliminating the gaps between separate caps where debris and rain enter. We size these on-site for Bellmore’s varied chimney dimensions and fabricate from stainless or copper depending on your preference and exposure.

Common Chimney Cap & Crown Problems We See in Bellmore Homes
- Salt-air crown cracking. Chimneys within several blocks of Bellmore Creek show mortar joint erosion a full generation ahead of identical-vintage homes a mile inland because South Shore bay-effect salt air chemically attacks mortar and accelerates crown and brick spalling. That means cap and crown work here often starts with repointing and crown rebuilding, not just a cap swap, on the same 1948-1968 Cape Cods that look identical farther north.
- Original terra-cotta liner failure. Original terra-cotta flue liners past their 50-year service life were never relined when homes converted from oil to gas, and wood-stove burning loads them with creosote the lining was never sized for. A cracked liner combined with a failed cap is how chimney fires start.
- Undersized or rusted caps letting in nor’easter rain. Rusted or undersized caps let nor’easter-driven rain and debris into the smoke chamber and damper, and the resulting moisture pushes first-degree creosote toward the tar-glaze stage a brush cannot remove. Bellmore’s coastal storms are particularly hard on caps that lack proper overhang and wind resistance.
- Freeze-thaw brick spalling after water intrusion. Once a crown crack or cap gap lets water into the masonry, winter temperatures do the rest. Spalled brick faces, deteriorated mortar, and eventually structural looseness follow. Catching it early with a camera inspection saves the chimney. Waiting costs the rebuild.

FAQs - Chimney Cap & Crown in Bellmore
The salt-laden marine air off the bay accelerates mortar erosion and crown deterioration on chimneys within several blocks of Bellmore Creek and the waterfront, often by a full generation compared to identical homes farther north. Your chimney is not poorly built. It is simply fighting harder chemistry. Crown coating or rebuild with proper salt-resistant materials solves it. Call (631) 735-5125 for a free inspection and exact quote.
Wood stoves as primary heat source produce far heavier creosote loading than occasional fireplace use, so we recommend inspection every season and sweeping when creosote reaches 1/8 inch buildup, which for full-time wood heat in Bellmore often means annually or more frequently depending on wood moisture and burning practice. Dry hardwood, proper air control, and avoiding overnight smoldering all extend the safe interval. We document creosote levels with camera photos so you can see exactly what is in your flue. Call (631) 735-5125 to schedule before the burning season starts.
Custom caps are measured and fabricated to your chimney’s exact dimensions with welded stainless seams, proper overhang, and screen height matched to your flue size, while standard caps are mass-produced sizes that often leave gaps or sit too low. On Bellmore’s older multi-flue chimneys, a custom cap eliminates the weak points where separate caps meet and where nor’ester wind drives rain underneath. Call (631) 735-5125 and we’ll measure yours on the spot.
Yes. Moisture from a cracked crown mixes with first-degree creosote and accelerates its progression to second-degree tar glaze and third-degree hardened deposits that a standard brush cannot remove. In Bellmore’s climate, freeze-thaw cycles worsen the crown crack while the wet creosote becomes increasingly hazardous. We inspect both the crown and the flue condition together, photograph everything, and give you a prioritized plan. Call (631) 735-5125 for a free estimate.
Original terra-cotta liners in Bellmore’s 1948-1968 housing stock are typically past their 50-year service life and often show stress cracking from thermal cycling, especially where wood stoves now load more creosote than the original oil boiler did. A Level 2 camera inspection reveals hidden liner damage, smoke chamber deterioration, and creosote buildup that a simple cap swap would leave unaddressed. We do not quote crown work without knowing what is beneath it, because a new cap on a failed liner is money wasted. The inspection includes photos you can see and a plain-English verdict. Call (631) 735-5125 to schedule.
