We’ve been driving to Old Westbury for over 42 years. Our crews know the difference between a 1920s Phipps-era estate on Post Road with six original flues and a 1960s custom build off Jericho Turnpike. Dispatch and scheduling run from our New York City office, but the trucks that roll up your driveway carry technicians who’ve worked Gold Coast masonry before. That matters because our Chimney Cap & Crown team doesn’t guess at what’s wrong with a chimney. We run a camera, show you the footage, and quote from what we can both see.

Our Chimney Cap & Crown Services in Old Westbury

Custom Cap Installation

Old Westbury’s Gold Coast estates weren’t built to standard dimensions. A chimney serving three or four flues on a 1910 manor requires a cap measured to the inch, not pulled from a warehouse shelf. We fabricate and install custom caps from Copperfield and Gelco stock, sized to your exact stack configuration. At a 1920s estate on Post Road, our tech found the original terra-cotta flue tiles in a seldom-used library flue had fully separated from the soft historic brick under modern wood-burning conditions, spalling mortar exposing the stack to northwest winds. We specified a custom Copperfield multi-flue cap sized to the three-stack chimney and a Gelco crown coating over the rebuilt chimney crown, then re-flashed the base - the homeowner watched the entire camera run on our tablet before we quoted a dollar.

Multi-Flue Cap Installation

Properties with our Fireplace Services in Old Westbury often need caps that protect every flue opening without restricting draft. A single oversized cap can create down-drafting problems that fill your formal living room with smoke. We measure each flue’s height and position, then specify multi-flue caps from Olympia Chimney or Famco that maintain proper clearance. On Old Westbury estates with five to ten fireplaces, this is standard work for us, not a special order.

Crown Repair

The concrete crown at the top of your chimney is what keeps water from saturating the brick below it. On Old Westbury’s pre-WWII homes, original crowns were often poured too thin or without proper slope, and decades of freeze-thaw cycling have cracked them through. We remove deteriorated crown material, form a new pour with proper drip edges and slope, and seal the interface with the flue tiles. Nothing gets covered up. You’ll see the before and after on camera.

Crown Coating

Not every cracked crown needs a full rebuild. For crowns with sound structural integrity but surface deterioration, we apply Gelco crown coating - a flexible, waterproof membrane that bridges hairline cracks and sheds water for years. This is often the right call on estate chimneys where the original concrete is thick enough but the surface has weathered. We never recommend coating over a crown that’s structurally failed; the camera tells us which is which.

Cap Replacement

Galvanized caps rust through in five to seven years on Old Westbury chimneys exposed to coastal moisture and acidic flue gases. We replace failed caps with stainless steel or copper models from Gelco and Copperfield, properly sized and secured so they don’t blow off in the first winter storm. The old cap comes off, the flue condition gets documented, and the new cap goes on with proper clearance and screening.

Trusted Brands We Service in Old Westbury

We stock professional-grade cap and crown materials from Gelco, Olympia Chimney, and Famco - no builder-grade substitutes that fail in three seasons. For custom fabrication on estate chimneys, we work with Copperfield components sized to your exact stack dimensions. Because we carry inventory for Old Westbury’s common chimney configurations, most cap and crown replacements don’t require a second trip. The part that fits your flue is already on the truck.

Common Chimney Cap & Crown Problems We See in Old Westbury Homes

• Original terra-cotta flue tiles separate from lime mortar. On Old Westbury’s Gold Coast estates, an original terra-cotta flue tile that has begun to separate from its surrounding lime mortar will still look intact from the firebox - the failure is only visible from the rooftop under a Level 2 inspection, which is why cap-and-crown work here starts at the stack, not the hearth.
• Heavy leaf and seed debris from century-old canopy. Old Westbury’s oak and beech canopy dumps material into uncapped stacks each fall. Combined with infrequent use of formal fireplaces, that debris feeds creosote buildup that progresses from first-degree to glazed third-degree stages a standard brush cannot remove.
• Chimney swift nesting in seldom-used flues. Technicians working Old Westbury estates regularly find that seldom-used library or formal dining room fireplaces have hosted multiple seasons of chimney swift nesting - a federally protected species whose active nests cannot legally be removed - forcing scheduling delays for homeowners who waited until fall to call.
• Improperly converted coal stacks venting modern appliances. Many Old Westbury chimneys were engineered for coal burning and never properly relined when converted to wood or gas. The cap and crown may look sound while the flue interior is deteriorating, a condition only visible by camera.
