Elmont’s housing tells a clear story: thousands of homes built during Nassau County’s 1945–1965 suburban boom, most heated by oil originally, many converted to gas decades ago without proper relining. Those 60–75-year-old single-stack chimneys — the kind that vent both your fireplace and your furnace through adjacent flues — weren’t designed for modern gas appliances. The thermal cycling alone cracks clay tile liners. Add Nassau County’s brutal freeze-thaw cycles, where temperatures cross 32°F dozens of times each winter, and water infiltrates every hairline crack in the crown, expands, and turns solid brick into gravel. Western Nassau’s coastal moisture from Jamaica Bay keeps that masonry damp year-round. This isn’t theoretical for us. On a 1952 Cape Cod on Elmont Road, we found the original brick crown reduced to gravel by freeze-thaw spalling and a missing cap that had allowed a raccoon to nest inside the flue. We installed a custom copper multi-flue cap and applied a crown coating to seal the deteriorated surface, ensuring the dual-flue stack could safely vent the gas furnace and fireplace.
Why Apex Chimney Cleaning Greater New York Is Elmont’s Preferred Chimney Cap & Crown Company
We’ve earned our reputation in Elmont one chimney at a time. Our Chimney Cap & Crown team has serviced homes from the dense blocks near Hempstead Turnpike to the quieter streets west of Dutch Broadway, and word travels fast in a tight-knit community where neighbors compare notes on contractors.
Our 1,096 verified customer reviews averaging 4.7 stars include dozens from Elmont homeowners specifically — people who’ve watched Robert Garcia climb their roof, diagnose the problem, and fix it himself rather than dispatching an anonymous crew. That owner-as-technician accountability matters when you’re trusting someone with a 60-year-old masonry stack.
Response time to Elmont is typically 24–48 hours for standard appointments, with emergency calls for active water intrusion or animal entry handled same-day when possible. We carry Gelco and Copperfield caps in common sizes, plus custom-fabrication capability for Elmont’s non-standard dual-flue configurations.
Robert knows the local permit history too — many of Elmont’s oil-to-gas conversions were done without proper relining permits in the 1970s and 1980s, leaving a paper trail gap that complicates insurance claims when crowns fail. He’s documented this pattern for homeowners navigating those conversations.
Our Chimney Cap & Crown Services in Elmont
Crown Repair
Crown repair in Elmont runs $350–$650 for most jobs, depending on how far the spalling has progressed. Original brick crowns on Elmont’s 60-plus-year-old chimneys rarely survive intact — the freeze-thaw cycles here are too aggressive, and decades of oil-to-gas conversion thermal stress finish the job. We remove deteriorated material down to sound concrete, then pour a new sloped crown with proper overhang and drip edge to shed water away from the brick. For crowns with moderate surface damage but sound structure, we apply a specialized crown coating that seals hairline cracks and restores waterproofing without full replacement.
Multi-Flue Cap Installation
Multi-flue caps in Elmont cost $550–$1,200 installed, with custom stainless or copper fabrication at the higher end. This is the cap Elmont needs most — and the one most often missing. A large share of Elmont’s Cape Cods were built with a single chimney stack housing both a fireplace flue and the original oil-burner flue side by side. When the oil system was swapped for gas, the oversized oil flue was often left bare, and sweeps here routinely find that same unlined, draft-starved flue still venting a gas furnace decades later. A multi-flue cap covers both flues simultaneously, preventing debris and wildlife entry while improving draft dynamics. We measure on-site and fabricate to fit your exact flue spacing — no off-the-shelf guesswork.
Custom Cap Fabrication
Custom caps for Elmont’s non-standard chimneys range from $750–$1,400, depending on metal choice and complexity. Many Elmont homes have odd flue configurations — offset flues, oversized original oil flues, or chimneys modified by previous owners. We template on the roof, then fabricate in copper or stainless steel with proper screen mesh to keep out squirrels, raccoons, and the dense leaf debris from Elmont’s mature oak canopy. Copper develops a protective patina that handles coastal salt moisture better than painted steel in western Nassau’s damp climate.
Crown Coating
Crown coating in Elmont is $280–$450 and buys time on a crown that’s cracked but structurally sound. This isn’t a permanent fix for advanced spalling — we won’t apply it to gravel. But for crowns with surface cracking and minor deterioration, a flexible elastomeric coating seals against water penetration and can extend service life 5–10 years. Given Elmont’s freeze-thaw severity, we recommend coating as preventive maintenance on crowns showing early wear, before the damage requires full rebuild.

Trusted Brands We Service in Elmont
We install professional-grade materials from Gelco, Copperfield, and DuraFlex — the same lines commercial contractors use, not big-box retail versions. For Elmont’s coastal-adjacent climate, we typically recommend copper or 304 stainless over galvanized steel; the salt-laden moisture from Jamaica Bay accelerates rust on lesser metals. We stock common Gelco and Copperfield multi-flue sizes for faster turnaround on Elmont jobs, and our custom fabrication shop handles everything else. When Robert specifies a material, he’s choosing based on 17 years of watching what survives on Nassau County roofs.
Common Chimney Cap & Crown Problems We See in Elmont Homes
- Freeze-thaw spalling on original brick crowns. Elmont’s winters deliver dozens of freeze-thaw cycles annually. Water enters micro-cracks in 60-year-old mortar, expands when frozen, and pops off brick faces until the crown is reduced to loose aggregate. We’ve replaced crowns on homes where the original 1950s concrete cap had completely disintegrated.
- Missing caps exposing dual flues to wildlife and debris. Without a cap, squirrels and raccoons enter freely — we’ve removed nests from flues on Covert Avenue and Dutch Broadway — while rain and leaves accelerate liner deterioration. The problem compounds when an unlined oil flue is already struggling to draft properly.
- Improper draft from bare oil flues venting gas appliances. Elmont’s oil-to-gas conversions left many chimneys with oversized, unlined flues that never achieved proper draft for efficient gas combustion. The resulting moisture and condensation attacks the crown from inside while freeze-thaw hits from outside.
- Cracked clay tile liners from thermal cycling. Original clay liners weren’t designed for gas appliance temperature profiles. The repeated heating and cooling fractures tiles, allowing flue gases to contact the brick shell and accelerating crown deterioration through acid condensation.

FAQs — Chimney Cap & Crown in Elmont
The visible flue interior doesn’t reveal crown damage until water is already entering the system. Elmont’s 60-plus-year-old brick crowns have endured decades of freeze-thaw cycling and thermal stress from original oil heating — the concrete or mortar cap deteriorates independently of the flue liner. By the time you notice water stains or draft issues, the crown is often structurally compromised. Call (866) 884-9512 for a camera inspection that shows what’s actually happening at the top of your chimney.
If your single chimney stack vents both a fireplace and a gas furnace through separate flues, yes — a multi-flue cap is the correct protection. Elmont’s Cape Cods were built this way, and the original oil flue left bare after conversion is particularly vulnerable to debris entry and draft problems. A properly sized multi-flue cap covers both flues, improves airflow dynamics, and prevents the animal intrusions we see constantly in this neighborhood. Robert can measure your exact flue spacing and specify the right cap on-site.
A crown coating works only if the underlying structure is sound and the damage is primarily surface cracking — typically $280–$450 in Elmont. If the crown has deteriorated to loose gravel, exposes rebar, or shows deep fractures through the full thickness, coating will fail within a season and full rebuild ($650–$1,100) is necessary. We never recommend coating as a Band-Aid on structural failure; Robert assesses this honestly during the free estimate.
Copper outperforms galvanized steel in Elmont’s damp, salt-influenced environment and typically costs $950–$1,400 installed. Western Nassau’s chronic moisture from Jamaica Bay accelerates corrosion on lesser metals — we’ve replaced steel caps that failed in under five years. Copper develops a protective patina and routinely lasts 20-plus years with minimal maintenance. For homeowners planning to stay long-term, the higher upfront cost pays back in longevity.
Backdrafting from a deteriorated crown usually shows as moisture stains on the chimney breast, a persistent musty smell near the fireplace, or the carbon monoxide detector triggering intermittently — but these symptoms have multiple causes. In Elmont’s oil-to-gas conversion chimneys, the problem is often a combination of an unlined, oversized flue and a cracked crown allowing cold air infiltration that disrupts draft. A camera inspection and draft test confirm whether the crown is the primary factor or if liner work is also needed. Call (866) 884-9512 — we’ll diagnose it properly and give you a straight answer.
