Fast, Reliable Chimney Cap & Crown Across Westbury
Chimney cap and crown repair in Westbury typically runs $280–$750 depending on whether we’re sealing a cracked crown or fabricating a custom cap for a non-standard flue, and most jobs are completed in a single visit. If your chimney crown is spalling or your cap is missing entirely, water is already getting into your masonry — and in Westbury’s climate, that damage accelerates fast.
We’ve been driving to Westbury from our New York City base for 17 years, and we know the village’s streets well: Post Avenue, Old Country Road, the winding lanes near Ellison Avenue where postwar ranches sit on generous lots with detached workshops and outbuildings. Robert Garcia, our owner and lead technician, handles these calls personally. When you book with Apex Chimney Cleaning Greater New York, you’re not getting a dispatched subcontractor who needs GPS to find the Northern State Parkway exit. You’re getting Robert on your roof, measuring your flue, and making the call on whether a Gelco crown coating will suffice or that crown needs a full rebuild. Call (866) 884-9512 for a free estimate — we typically reach Westbury properties within 90 minutes during business hours.
Why Apex Chimney Cleaning Greater New York Is Westbury’s Preferred Chimney Cap & Crown Company
Our reputation in Westbury is built on showing up and solving problems that other companies walk away from. We’ve got 1,096 verified customer reviews averaging 4.7 stars, and a significant share of those come from Nassau County homeowners who needed someone willing to fabricate a custom solution rather than force a standard catalog part onto an odd-sized chimney.
Robert Garcia doesn’t delegate the technical work. He’s the one climbing the ladder, inspecting the crown with a flashlight, and explaining to you why your 1952 ranch chimney is failing differently than your neighbor’s newer construction. That owner-as-technician model means decisions get made on the spot — no callbacks, no “the office will get back to you,” no waiting for a manager’s approval to proceed with a repair.
Our response time to Westbury is consistently under two hours because we know the route: Long Island Expressway to the Meadowbrook or Northern State, then straight into the 11590 ZIP. We’ve worked on chimneys from the Salisbury side near the county line down to the New Cassel border, and we understand how Westbury’s proximity to Hempstead Harbor and the Atlantic creates unique wear patterns on masonry that inland Nassau County doesn’t see.
Local knowledge matters. We know that a chimney on a Westbury acreage property with a detached workshop isn’t just another cap job — it’s often a multi-flue configuration with non-standard tile sizes, sometimes with one flue abandoned and another oversized from an old oil-to-gas conversion. Our Chimney Cap & Crown team measures twice and builds once.
Our Chimney Cap & Crown Services in Westbury
Multi-Flue Cap Installation
Westbury’s larger properties — especially those near Ellison Avenue and the more spacious lots south of Old Country Road — often have detached garages, workshops, or guest cottages with chimneys serving multiple appliances. These aren’t standard single-flue setups. A typical multi-flue cap installation in Westbury runs $450–$850 because we frequently need to span two or three flues of different diameters, sometimes including one that’s been abandoned and needs sealing. We fabricate these on-site after precise measurement, using copper or stainless steel from Copperfield or Famco depending on your budget and the salt-air exposure your chimney faces.
Custom Cap Fabrication
Generic big-box caps don’t fit Westbury’s odd-sized flues. We’ve measured 8-inch, 10-inch, and even 12-inch clay tile liners in the same chimney — remnants of oil-to-gas conversions where the original oversized flue was never properly relined. A custom cap in Westbury typically costs $380–$720 and requires us to build a mounting system that accounts for deteriorated crown edges, spalling brick, or non-standard flue projections. Robert Garcia brings the fabrication tools to your property and builds the cap to your chimney’s exact dimensions, not the other way around.
Crown Repair
The crown is the concrete slab that seals the top of your chimney between the flue tiles. In Westbury, crown failure is epidemic. Salt-laden air from Hempstead Harbor penetrates the porous concrete, and then winter’s freeze-thaw cycles — sometimes dozens of cycles per season — pop the surface apart. We’ve repaired crowns on Post Avenue ranches and Salisbury Road Capes where the crown was crumbling so badly that water had already saturated the chimney breast inside the home. Crown repair in Westbury runs $280–$550 for standard rebuilds using high-strength concrete with proper overhang and drip edges.
Crown Coating
For crowns with early-stage cracking but intact structural integrity, we apply a flexible crown coating — typically Gelco or HeatShield products — that bridges hairline cracks and prevents water penetration. This is a cost-effective preventive treatment, usually $180–$320 in Westbury, and it’s especially valuable on chimneys where the crown is sound but the surface has begun to check from salt and thermal stress. We recommend this for Westbury homeowners whose crowns are 10–15 years old and showing first signs of wear, before full rebuild becomes necessary.

Trusted Brands We Service in Westbury
We install professional-grade materials from the same suppliers that commercial chimney contractors use: Copperfield for custom copper and stainless fabrication, Gelco for crown coatings and sealants, and Famco for standard and multi-flue cap assemblies. We don’t order from a catalog and hope it fits — we stock common sizes and fabrication materials locally, which means when Robert Garcia arrives at your Westbury property, he’s got what he needs to measure, cut, and install without a second trip. That matters on acreage properties where the workshop chimney is 200 feet from the driveway and you don’t want a technician discovering he’s short a bracket and rescheduling for next Thursday.
Common Chimney Cap & Crown Problems We See in Westbury Homes
- Crown spalling from salt-laden air and freeze-thaw cycles. Westbury’s location within a few miles of Hempstead Harbor means salt aerosols penetrate concrete crowns year-round. When winter temperatures cycle above and below freezing — common in Nassau County from December through March — that trapped moisture expands and fractures the crown surface. We see this on virtually every 1950s chimney we inspect in the 11590 ZIP.
- Corroded clay tile liners from oil-to-gas conversion condensate. Westbury’s housing stock converted en masse from oil heat to gas in the 1970s and 1980s, but most homeowners never relined the oversized flues designed for oil combustion. The acidic condensate from gas appliances eats clay tile from the inside out, leaving gaps where a cap can’t seal properly and carbon monoxide can leak into living spaces.
- Non-standard flue openings on detached workshops and outbuildings. Westbury’s larger lots often have secondary structures with chimneys built by different contractors at different times. Flue sizes vary, tile projections are irregular, and the standard 8×13 or 13×13 caps simply don’t fit. Water pours in, squirrels nest, and the chimney deteriorates unseen because nobody checks the workshop chimney annually.
- Missing or improperly installed caps on original 1950s construction. Many Westbury ranches and Capes were built with simple terracotta flue caps or no cap at all. After 65–80 years of exposure, these are gone or crumbled, leaving the flue open to direct rainfall, leaf debris from mature oak and maple canopies, and animal intrusion. A proper cap installation prevents the water damage that leads to crown failure in the first place.

What moves you up or down within these ranges? Crown height and accessibility matter — a two-story Cape with a steep roof costs more than a single-story ranch. The condition of existing brick and mortar affects whether we can mount a cap directly or need to rebuild the top course first. And custom fabrication for non-standard flues requires additional material and shop time. We don’t guess at estimates over the phone for custom work — Robert Garcia needs to see the chimney, measure the flues, and assess the crown condition. Call (866) 884-9512 to schedule a free, no-obligation estimate. We’ll give you a firm price before any work begins.

FAQs — Chimney Cap & Crown in Westbury
Because the original oversized flues designed for oil combustion create draft problems and excessive condensation when venting gas appliances, and standard caps can’t seal the deteriorated tile surfaces that result. In Westbury, we’ve inspected hundreds of chimneys where the clay liner is cracked and flaking from years of acidic condensate — a cap that merely covers the flue opening doesn’t address the underlying liner failure. We often recommend a custom cap combined with a liner inspection, especially if your home converted from oil to gas more than a decade ago. Call (866) 884-9512 and we’ll assess whether your flue needs more than just a cap.
A poured concrete crown rebuild with proper overhang, drip edge, and expansion joints performs best in Westbury’s coastal freeze-thaw climate, though early-stage damage can be addressed with a flexible crown coating. Salt-laden air from Hempstead Harbor penetrates standard concrete mixes, so we use high-strength, low-porosity concrete with added bonding agents for Westbury rebuilds. For crowns with surface cracking but solid structure, Gelco crown coating provides a waterproof, flexible membrane that bridges hairline cracks through multiple freeze-thaw cycles. Robert Garcia evaluates each crown individually — call for a free inspection and he’ll tell you which approach fits your chimney’s condition.
Yes — custom cap fabrication is one of our specialties, and Westbury’s acreage properties with detached workshops are exactly why we carry fabrication equipment on our service vehicles. On a property near Ellison Avenue, our crew found a detached workshop chimney where the original 8-inch clay tile flue had deteriorated from years of acidic gas condensate after an oil-to-gas conversion. We installed a custom copper multi-flue cap from Copperfield to seal all three flues, and applied a Gelco crown coating to prevent further salt-air and freeze-thaw damage. Whether your flue is round, square, oversized, or offset from center, Robert Garcia measures on-site and builds the cap to fit. Call (866) 884-9512 to schedule — bring photos if you have them, but we’ll confirm measurements in person.
Annually, without exception — and we recommend inspecting both your main house chimney and any detached structure chimneys every year. Westbury’s combination of salt-air corrosion, freeze-thaw cycling, and mature tree canopy debris means caps deteriorate faster here than in inland locations. A cap that looked fine in October can be rusted through or dislodged by March. Many Westbury homeowners only discover cap failure when water stains appear on the ceiling or a squirrel gets into the flue. Annual inspection catches problems before they require crown rebuilds or interior repairs. Call us to add your Westbury property to our inspection schedule.
We primarily fabricate multi-flue caps from Copperfield copper and stainless steel, and we use Famco for standard multi-flue assemblies when the flue configuration is regular enough to accommodate a manufactured product. For Westbury’s non-standard flues — common on detached workshops and converted oil chimneys — Robert Garcia builds custom caps in copper or stainless depending on your preference and budget. Copper develops a protective patina that performs exceptionally well in salt-air environments, while stainless offers lower cost with similar durability. We’ll show you material samples and explain the trade-offs when we visit your property for a free estimate.
