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 Bellmore
Chimney cap and crown repair in Bellmore typically runs $280-$950 depending on whether you’re replacing a corroded cap, coating a cracked crown, or addressing both after salt-air damage. Most jobs are completed in a single visit with upfront pricing agreed before we start. If you’re seeing rust streaks on your chimney, water in the firebox, or pieces of concrete on your roof, call (516) 614-4632 - we’ll send a technician to your Bellmore home, document what we find with photos, and give you a plain-English verdict you can act on.
We’ve been working on South Shore chimneys for over 42 years, and Bellmore’s combination of postwar housing stock and salt-laden coastal air creates problems we see nowhere else in Nassau County. Our crews serve Bellmore directly from our New York City office, and we know the difference between a chimney on Bedford Avenue inland and one three blocks from Bellmore Creek. That local knowledge matters when we’re specifying materials that have to survive this environment.
Why Hearthstone Chimney Co. Is Bellmore’s Preferred Chimney Cap & Crown Company
Bellmore homeowners call us because we document every inspection. Our Level-2 camera inspection ends with photos you can see and a plain-English verdict - no jargon, no scare tactics, just what is wrong and what it costs to fix. We’ve built our reputation on the 90-Day Done Right Promise: if it’s not right, we come back, in writing, no arguing.
Our reviews from Bellmore customers consistently mention the same things - that we showed them photos of their cracked crown or rusted cap before recommending work, that the price on the estimate matched the invoice, and that a live person answered the phone when they called. Calls are answered 24 hours a day, 7 days a week, by a live person, not a voicemail system or callback queue.
Our response time to Bellmore is typically same-week scheduling during the spring and summer, and we prioritize cap and crown work before burning season because a failed crown or missing cap lets water into your flue year-round. Our technicians are background-checked, uniformed, and carry professional-grade materials from Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes that won’t hold up to South Shore conditions.
We understand Bellmore’s housing stock. Most chimneys here are original to 1950s-1960s Cape Cods, ranch homes, and split-levels, now 60-plus years old, with clay flue tile liners that have survived decades of oil-to-gas conversion condensation. When we inspect a chimney in Bellmore, we’re looking for the specific failure patterns this age and this coastal air produce.
Our Chimney Cap & Crown Services in Bellmore
Cap Installation
New cap installation in Bellmore starts at $280 for a standard single-flue unit, with multi-flue caps and custom sizes running higher. On homes near Bellmore Creek and the bay, we specify stainless steel as the default - galvanised caps simply don’t last here. Our Chimney Cap & Crown team measures your flue precisely, checks for proper clearance, and installs a cap that vents properly while keeping rain, animals, and salt air out of your flue.

Cap Replacement
This is our most common call in Bellmore. Galvanised caps on salt-exposed blocks rust through at welds and seams within years, letting water straight into the flue and firebox. Cap replacement runs $280-$550 for most Bellmore homes, with stainless multi-flue caps at the higher end. We remove the corroded unit, inspect the flue opening for hidden damage, and install a replacement rated for coastal exposure. No surprises on the bill - the estimate number is the invoice number.

Crown Repair
The concrete crown at the top of your chimney is the first defense against water intrusion, and in Bellmore it’s under constant assault. Salt air and freeze-thaw cycles spall uncoated mortar, opening cracks that let water soak the brick and interior. Crown repair typically runs $450-$750 depending on whether we’re patching localized damage or rebuilding the entire crown. We use professional-grade materials and specify a flexible crown coating on every repair to seal against future cracking.

Crown Coating
Crown coating is preventive maintenance that pays for itself in Bellmore’s climate. For $350-$550, we clean and prep the existing crown, repair minor cracks, and apply a flexible, waterproof coating that bridges hairline cracks as the concrete expands and contracts. We recommend this every 5-7 years on coastal chimneys - more frequently if your home is within a few blocks of the bay. It’s far less expensive than rebuilding a saturated crown, and it extends the life of your chimney’s most vulnerable component.

Multi-Flue Cap
Many Bellmore split-levels and larger Cape Cods have multiple flues sharing a single chimney chase. A multi-flue cap covers the entire assembly with one properly vented unit, eliminating the gaps between individual caps where water and salt air penetrate. Multi-flue caps run $550-$950 installed in Bellmore, with stainless construction standard for coastal homes. We measure on-site, fabricate to fit, and install with proper clearances for each flue.

Custom Cap
Non-standard flue sizes, decorative chimney pots, or historic reproductions require custom fabrication. Custom caps in Bellmore start around $750 and are typically completed in two visits - measure and fabricate, then install. We work with Copperfield and Famco for specialty orders, and every custom unit carries the same 90-Day Done Right Promise as our standard installations.

Trusted Brands We Service in Bellmore
We stock and install professional-grade materials from Olympia Chimney, Famco, and Copperfield - brands that manufacture for coastal conditions, not big-box shelves. For Bellmore customers, this means faster turnaround because we’re not ordering parts that take weeks to arrive. A stainless cap from Olympia Chimney or a crown coating system from Famco is specified knowing it will face salt air, freeze-thaw, and the occasional nor’easter. We don’t use builder-grade substitutes that save a few dollars upfront and fail in five years. Done right - and we stand behind it.
Common Chimney Cap & Crown Problems We See in Bellmore Homes
- Galvanised caps rusted through at the seams. On streets near Bellmore Creek, we regularly find galvanised steel caps that have rusted through within 3-5 years. The salt-laden air accelerates corrosion at welds and joints, creating gaps that let water pour into the flue during every rain. Stainless replacement is the only lasting fix.
- Uncoated crowns cracked in hidden radial patterns. Salt air and freeze-thaw spalling crack mortar crowns from the top down, often in patterns that aren’t visible from the ground. Water soaks through these cracks, saturating the brick and accelerating deterioration of the clay flue liner below. Crown coating or rebuild stops the cycle.
- Corroded flashing pulling away from the chimney. The metal flashing where your chimney meets the roof is another salt-air casualty in Bellmore. When flashing corrodes, water runs behind it and into the structure, often showing up as stains on interior walls long after the damage has begun.
- Original clay flue liners spalled from decades of condensation. Bellmore’s postwar chimneys were built for oil heat, then converted to natural gas without proper relining. The resulting acidic condensation, combined with moisture from failed caps and crowns, spalls the clay flue tile from the inside out. We catch this during our Level-2 inspection.

FAQs - Chimney Cap & Crown in Bellmore
Your Bellmore chimney sits within a few miles of salt water, and the prevailing winds carry corrosive salt spray inland year-round. Galvanised steel in this environment loses its protective zinc coating measurably faster than in inland Nassau suburbs like Mineola or Garden City, which is why we specify stainless steel as the default for cap replacement on any Bellmore home, especially those near Bellmore Creek. Call (516) 614-4632 for a free inspection and we’ll show you exactly what your cap looks like from the top.
Chimneys within a few blocks of Bellmore Creek and the South Shore bays should be inspected annually and swept as needed, with cap and crown condition checked every year. The salt-laden air accelerates corrosion and spalling to a degree that justifies more frequent attention than the NFPA 211 baseline. If your home is on a block that flooded during Sandy, we strongly recommend a Level-2 inspection with camera documentation even if you’ve never had one. Call (516) 614-4632 to schedule - estimates are free.
Yes, and it’s a pattern we see constantly in Bellmore. On streets closest to Bellmore Creek, technicians consistently find that post-Sandy HVAC replacements included informal “clearing” of the chimney for venting, but no professional sweep or inspection for liner damage, debris, or proper sizing. The flue may be partially blocked, improperly lined for gas conversion, or hiding spalled clay tile from decades of condensation. We recommend a Level-2 camera inspection to document exactly what condition your flue is in. Call (516) 614-4632 - we’ll show you the photos and give you a plain-English verdict.
The cap usually shows visible failure first: rust streaks, gaps at seams, or missing pieces you can spot from the ground. But the crown often fails simultaneously in hidden ways - hairline cracks that let water in without obvious exterior damage. Flashing corrosion typically follows, though on homes with poor attic ventilation, flashing failure can accelerate crown damage from below. During our inspection, we photograph all three from the roof and from inside the flue so you know the full picture before deciding what to address. Call (516) 614-4632 for a documented assessment.
For any Bellmore home, especially within a mile of the bay, we recommend stainless steel. The additional cost over galvanised - typically $80-$150 on a standard single-flue cap - is recovered many times over in lifespan. Galvanised caps near Bellmore Creek routinely fail in 3-5 years; stainless units last 15-20 years in the same conditions. We won’t install galvanised on a coastal chimney unless a homeowner specifically requests it after understanding the tradeoff. Call (516) 614-4632 and we’ll explain the options for your specific flue size and location.
On a 1950s Cape Cod near Bellmore Creek that had flooded during Sandy, our tech found a galvanised cap rusted through at the seams and a crown cracked in a hidden radial pattern, with salt-softened mortar joints crumbling around the flashing. We replaced the cap with a stainless multi-flue unit, rebuilt the crown and sealed it with a flexible coating, then ran a Level 2 inspection on the clay flue liner, which showed spalling from decades of use. The homeowner, who had never had the chimney professionally serviced after a post-storm HVAC replacement, finally had a sound crown, cap, and flue.
Chimneys within a few blocks of Bellmore Creek and the South Shore bays corrode from salt-laden air year-round, so galvanised steel caps and uncoated crowns on these blocks typically fail years before identical components on inland Nassau chimneys, making stainless caps and crown coating the default specification near the water. This isn’t theoretical - we document it on every roof we climb. If your home is on Shore Road, Newbridge Road near the creek, or any of the blocks that took water during Sandy, your chimney is almost certainly aging faster than the same construction would in Garden City or Mineola. The good news is that the right materials, properly installed, last decades even here.
