Our Chimney Cap & Crown Services in North Merrick
Crown Repair
Crown repair is what we do most often in North Merrick, and there’s a reason. The original crowns on these 1950s and 1960s chimneys were poured with mortar mixes that weren’t designed to withstand decades of salt-laden marine air off the South Shore. Add annual freeze-thaw cycles, and you get surface spalling, hairline cracks that widen every winter, and water intrusion that rots the top course of brick. We grind out deteriorated material and rebuild with professional-grade crown formulations, then seal with a flexible coating that moves with the masonry. A square deal: no surprises on the bill.
Multi-Flue Cap Installation
Most North Merrick chimneys have two flues - one for the fireplace, one for the furnace - and a single-flue cap leaves the other exposed or requires an awkward, leaky fit. Our multi-flue caps cover both flues with a single, properly sized top that sheds water and keeps animals out. On a 1954 split-level on Scranton Avenue, we found a copper custom cap that had salt-corroded at the seams and a crown with surface spalling from freeze-thaw. We replaced the cap with a Famco multi-flue stainless model and applied a Gelco crown coating to seal the cracks, solving the draft issues that had plagued the homeowner after converting to gas heat. Multi-flue caps are our recommendation for most homes in the 11575 ZIP code.
Custom Cap Fabrication
Some North Merrick chimneys need more than an off-the-shelf solution. Older masonry with irregular dimensions, decorative brickwork, or multiple flues at different heights demands a custom cap measured and fabricated to fit. We work with Copperfield and Gelco materials to build caps that match your chimney’s exact profile. Stainless construction resists the salt air that destroys lesser metal in under a decade. Done right - and we stand behind it.
Crown Coating
For crowns with early-stage cracking but sound structural integrity, a professional crown coating can add years of life. We use flexible, breathable coatings that seal hairline cracks without trapping moisture inside the masonry. In North Merrick’s climate, where freeze-thaw is relentless and salt accelerates every failure, this preventive step often saves a full rebuild. We’ll show you the photos and give you the straight answer: coat it now, or rebuild it later.
Cap Replacement
Standard caps last 7-15 years in inland climates. In North Merrick, we’ve seen galvanized caps rust through in under 10 years from the combination of salt air and acidic condensate. When we replace a cap, we upgrade the material - stainless steel or copper - and inspect the crown beneath it. The cap is only as good as what it sits on.

Trusted Brands We Service in North Merrick
We stock parts and materials from DuraFlex, HeatShield, Gelco, and Famco - brands that hold up in coastal environments, not builder-grade substitutes that fail early. For North Merrick homeowners, that means faster turnaround. We’re not ordering parts and making you wait two weeks. Our trucks carry the components these chimneys need, and our technicians know which brand fits which application. A multi-flue cap from Famco for the standard two-flue setup. Gelco coating for the crown that needs sealing, not rebuilding. HeatShield for liner restoration when the gas conversion has left the flue damaged. The right material for the specific problem, installed by people who understand what this salt air does.
Common Chimney Cap & Crown Problems We See in North Merrick Homes
- Salt-air corrosion of metal caps. North Merrick sits only 3-4 miles inland from the Great South Bay, close enough that salt-laden marine air off the South Shore measurably accelerates mortar joint erosion and brick spalling on exposed chimney sections. Galvanized caps rust at the seams. Stainless steel resists it.
- Acidic condensate from oversized gas flues. North Merrick’s post-war chimneys were built for oil burners, and the conversion to gas leaves oversized flues that condense acidic moisture, destroying crowns and caps from the inside out. The condensate pools on the crown, eats through metal, and stains the masonry below.
- Freeze-thaw splitting of crowns. Annual nor’easters and hard freeze-thaw cycles further stress chimney crowns and step flashings, making late-fall inspections before heating season a consistent service driver here. Water enters a hairline crack, expands when it freezes, and the crack grows. By spring, you have a crown in pieces.
- Dislodged caps from shifting crowns. When a crown cracks and settles, the cap anchors lose their grip. We’ve found caps tilted or blown off entirely after storms, leaving the flue open to rain, leaves, and animals. The cap didn’t fail - the crown underneath it did.
Pricing for Chimney Cap & Crown in North Merrick, NY
A typical cap replacement in North Merrick runs $340-$580 for a standard stainless single-flue model, or $520-$780 for a multi-flue cap with proper screening.

FAQs - Chimney Cap & Crown in North Merrick
Yes, unfortunately, and we see it constantly on Jerusalem Avenue and the streets around Camp Avenue. The combination of salt-laden marine air and acidic condensate from oversized gas flues destroys standard galvanized caps in 7-10 years here, half the inland lifespan. We replace them with stainless steel or copper models that resist both threats. Call (855) 950-3861 and we’ll measure for a proper fit - estimates are free.
Yes, a multi-flue cap is the right choice for most North Merrick homes because your chimney almost certainly has two flues - one for the fireplace, one for the heating appliance - and covering both with a single properly sized cap prevents water intrusion and animal entry at every opening. Single-flue caps on dual-flue chimneys leave gaps or require awkward retrofits that leak. Our multi-flue installations use Famco stainless models with proper height clearance for draft performance. Photos you can see, a plain-English verdict.
Repair with a professional crown coating if the cracks are surface-level and the crown structure is sound; replace if the cracks are deep, widespread, or the crown is spalling or separating from the brick. In North Merrick’s freeze-thaw climate, hairline cracks become major failures over one hard winter. We inspect with a Level-2 camera, show you the photos, and give you the straight recommendation - coat it now for $380-$650, or rebuild later for $680-$1,240. Call (855) 950-3861 before the first hard freeze.
A new cap alone won’t fix draft problems caused by an oversized flue, but the right cap combined with proper flue sizing or liner work can restore performance. The root issue in most North Merrick conversions is the flue diameter - built for oil, too large for gas, causing chronic condensation and weak draft. We assess the full system: flue size, liner condition, crown integrity, and cap design. Sometimes the cap is part of the solution. Sometimes the liner needs addressing first. We’ll show you exactly what we find.
Expect 10-15 years from a quality stainless cap in North Merrick’s salt-air conditions, compared to 15-25 years inland. Galvanized caps often fail in 7-10 years. We recommend inspection every 2-3 years, with particular attention after nor’easters. Our 90-Day Done Right Promise covers every installation, and we document condition with photos so you can track wear over time. Call (855) 950-3861 to schedule - estimates are free, and we’ll be there when we say.
