Fast, Reliable Chimney Cap & Crown Across Westbury
Chimney cap and crown work in Westbury typically runs $280–$890 depending on whether you’re sealing surface cracks or installing a full custom multi-flue cap, and most jobs are completed in a single visit. We make the drive from Bridgeport to Westbury regularly — usually within 90 minutes for scheduled work, same day when the schedule allows.

Westbury’s housing stock is specific — post-WWII Cape Cods and colonials built during the late 1940s through 1960s suburban boom, with a pocket of older Victorians near the village center. These homes weren’t built for today’s heating demands, and their chimneys weren’t built for Long Island’s salt-laden humidity. We’ve spent eight years working on chimneys exactly like yours, and we know where they fail.
Why Premier Chimney Cleaning Connecticut Is Westbury’s Preferred Chimney Cap & Crown Company
Anthony Perez, our owner, leads every job personally — not a subcontractor, not a seasonal hire. When you call us for work on your Westbury home, Anthony is the one climbing the ladder, reading the flue, and making the call on whether your crown can be coated or needs full rebuild. That accountability matters on a 60-year-old chimney where one wrong diagnosis means water in your walls or carbon monoxide in your living room.
Our Chimney Cap & Crown team has earned 800+ customer reviews averaging 4.7 stars — volume that comes from doing the work right and standing behind it. Westbury homeowners specifically mention our willingness to explain what we’re seeing, why it matters, and what happens if they wait. We’re not the cheapest quote you’ll get, and we’re fine with that. We’re the quote that doesn’t require a second contractor to fix what the first one missed.
Response time to Westbury averages under two hours for emergency calls — cracked crowns during a hard freeze, caps blown off in a nor’easter, backdrafting oil boilers. We know the local roads: Old Country Road, Post Avenue, the Maple Avenue corridor. That familiarity saves time when water’s pouring through your flue.
Our Chimney Cap & Crown Services in Westbury
Custom Cap Installation
Westbury’s distinctive problem is the multi-flue chimney serving both an oil boiler and a fireplace — sometimes properly separated, sometimes not. Standard big-box caps won’t cut it here. We fabricate and install custom caps with individual draft control for each flue, using DuraFlex stainless steel rated for acidic petroleum exhaust. A proper custom cap on a Westbury home prevents the backdrafting that sends oil-burner fumes down an unused fireplace flue — a hazard we’ve found in dozens of 1950s-era homes.
Cap Replacement
Corrosion happens fast in Westbury. The combination of acidic oil-burner exhaust and salt-laden Atlantic humidity eats through standard galvanized caps in three to five years. We replace failed caps with Gelco stainless steel or copper options — materials that last in this environment. On a recent job near the Westbury High School campus, we pulled a four-year-old galvanized cap that had rusted through at the seams. The replacement Gelco cap will outlast the roof.
Crown Repair
Original concrete crowns on Westbury’s post-war homes are 60–75 years old now. Freeze-thaw cycles crack them. Salt air penetrates those cracks, accelerates deterioration, and water follows. We repair structurally sound crowns with Olympia Chimney crown sealant and rebuild those too far gone. Crown repair in Westbury runs $280–$450 when the damage is surface-level; full rebuilds start around $680.
Crown Coating
Preventive crown coating is the smartest money you can spend on an aging Westbury chimney. We apply HeatShield crown coating to sound but porous concrete — the product bonds to existing material, fills hairline cracks, and creates a waterproof membrane. At $320–$480, it’s roughly half the cost of rebuild and extends service life 10–15 years in Westbury’s harsh coastal environment. We recommend it on every intact crown over 40 years old.
Multi-Flue Cap (Featured Service)
This is where Westbury’s housing stock demands real expertise. Multi-flue caps must cover multiple flues with proper separation, individual spark arrestors, and draft control. We measure on-site, fabricate to spec, and install with stainless steel fasteners — never the aluminum screws that corrode in two seasons here. Multi-flue cap installations in Westbury typically range $580–$890.

Trusted Brands We Service in Westbury
We stock DuraFlex, Gelco, and Olympia Chimney components specifically for the conditions we encounter in Nassau County — not hardware-store substitutes that fail in this environment. DuraFlex stainless steel handles acidic oil exhaust without pitting. Gelco caps carry a lifetime warranty against corrosion, which matters when you’re surrounded by salt water on two sides. Olympia Chimney crown products are formulated for freeze-thaw resistance in coastal climates. When we quote your Westbury job, the materials are already in our truck or available next-day from our Bridgeport warehouse. No waiting three weeks for special-order parts that might not fit.
Common Chimney Cap & Crown Problems We See in Westbury Homes
- Crumbling clay tile crowns from salt-laden humidity. On a Cape Cod home on Maple Avenue, we found an original 1950s clay tile cap crumbling from salt-laden humidity. We replaced it with a custom multi-flue DuraFlex stainless steel cap, sealing both the oil-boiler and fireplace flues separately, and applied a Gelco crown coating to prevent further erosion.
- Corroded metal caps on multi-flue chimneys. Acidic oil-burner exhaust and salt air combine to eat through standard galvanized steel in just a few years. We see this constantly in Westbury’s older neighborhoods where original caps were never upgraded.
- Improperly shared flues from 1950s construction. Technicians working Westbury’s older blocks regularly open up chimneys built to serve one oil boiler and discover a second, uncapped fireplace flue sharing the same chase — a common builder shortcut that violates modern code and creates backdraft and CO risks.
- Freeze-thaw damage to concrete crowns. Westbury’s winters are cold enough for sustained heating demand but mild enough for repeated freeze-thaw cycling. Water penetrates crown cracks, expands, and widens them. By year three of neglect, a $320 coating becomes a $750 rebuild.

FAQs — Chimney Cap & Crown in Westbury
Yes — oil exhaust is acidic and petroleum-based, which corrodes standard galvanized caps and requires stainless steel rated for that chemistry. We use DuraFlex stainless components for Westbury’s oil-heated homes, with separate draft control for each flue. Call (833) 719-7193 and we’ll inspect your current setup — estimates are free.
It’s urgent but not usually an immediate emergency unless water is actively entering. Westbury’s salt-laden humidity accelerates crack expansion dramatically — a hairline crack in October becomes a structural channel by March. Schedule inspection within two weeks; coating or repair now prevents rebuild later. Call (833) 719-7193 for a free look.
Absolutely, and this is our most common Westbury configuration. We install custom multi-flue caps with individual covers and spark arrestors for each flue, ensuring proper separation and draft. Shared chases from 1950s construction require this specific solution — standard caps create backdraft hazards. Call (833) 719-7193 to discuss your flue layout.
It’s normal for cheap galvanized steel in Westbury’s environment, but it’s not acceptable. The combination of acidic oil exhaust and coastal salt air destroys standard caps in 3–5 years. We replace them with Gelco stainless steel or copper options that carry lifetime warranties and actually last. Call (833) 719-7193 for pricing on a proper replacement.
Simple cap replacement on an existing flue typically does not require a permit in the Town of North Hempstead. Crown rebuilds or modifications to flue separation may trigger permitting, and we handle that paperwork as part of the job. We’ll tell you exactly what applies to your situation during the free estimate — call (833) 719-7193.
