We’ve been working on South Hempstead chimneys for decades. Our crews know the difference between a 1925 Cape Cod off Grand Avenue and a post-war bungalow near Peninsula Boulevard, and we know the chimneys in both were built for a different era of heating. Russell Haines built this company on the principle that a homeowner should see the problem before paying to fix it. That matters here, where so many stacks were converted from oil to gas without ever being relined or resized.

Dispatch and scheduling are coordinated from our New York City office, but our trucks are in Nassau County daily. We answer the phone with a live person 24 hours a day, 7 days a week. No voicemail. No callback queue.

Why Hearthstone Chimney Co. Is South Hempstead’s Preferred Chimney Cap & Crown Company

We’ve earned our reputation in South Hempstead one chimney at a time. Homeowners here talk. They mention the same things in reviews: the technician showed them the camera footage before recommending anything, the estimate matched the final bill, and someone actually picked up the phone at 7 p.m. on a Saturday.

Our response time to South Hempstead is typically same-week, often within two to three days of your call. We don’t overbook. We don’t send a crew from two counties away. These are local roads our techs drive regularly.

What separates us from the chains is local knowledge. We know that a crumbling crown on a 1940s Cape Cod in South Hempstead usually signals something deeper: an oversized flue venting a gas appliance into a stack that was built for coal. The cap and crown are symptoms. We document the cause with photos you can see, and we explain it in plain English. That’s the Keystone Standard.

Our Chimney Cap & Crown team carries the 90-Day Done Right Promise on every job. In writing. No arguing.

Our Chimney Cap & Crown Services in South Hempstead

Cap Installation

A properly sized cap keeps rain, animals, and wind-blown debris out of your flue. In South Hempstead, we install single-flue and multi-flue caps from Famco and Copperfield, sized to your specific flue count and stack dimensions. For homes that converted to gas without relining, we often recommend a multi-flue cap that covers the entire chimney top while we address the underlying flue sizing issue. A cap alone won’t fix a draft problem, but it’s the right first layer of protection.

Cap Replacement

Caps rust out faster in South Hempstead than they do inland. Salt-laden air off the Atlantic accelerates corrosion, especially on the windward side of the stack. We replace rusted or poorly fitted caps with stainless steel or copper models built to last in coastal conditions. Every replacement starts with a camera inspection of the flue beneath it. We’ve found too many cracked clay liners hidden under a bad cap to skip that step.

Crown Repair

The concrete crown at the top of your chimney is supposed to shed water away from the brickwork below. On South Hempstead’s pre-1955 chimneys, crowns are often too thin, improperly sloped, or cracked from decades of freeze-thaw cycles. We cut out deteriorated concrete and pour a new crown with proper overhang and slope, reinforced to shed water rather than trap it. For stacks with active mortar spalling, crown repair is urgent. Water gets in, freezes, and widens the cracks every winter.

Crown Coating

When the crown has minor cracking but the concrete is structurally sound, we apply a professional-grade flexible crown coating from HeatShield or DuraFlex. This seals hairline cracks and prevents new water intrusion without the cost of full crown replacement. It’s a practical solution for South Hempstead homeowners who caught the problem early. We won’t coat a crown that’s too far gone. The camera inspection and photo report tell us which path is right.

Multi-Flue Cap

Many South Hempstead homes have multiple flues in a single stack: one for the furnace, one for a fireplace or former oil burner. A multi-flue cap covers the entire chimney top with one integrated unit, eliminating the gaps between individual caps where water and animals get in. We size and install these for the specific footprint of your stack, not with off-the-shelf guesses.

Custom Cap

Odd-sized flues, decorative pots, or heritage brickwork require custom fabrication. We measure on-site and source custom caps in stainless steel or copper that fit properly and vent correctly. No gaps. No improvisation.

Trusted Brands We Service in South Hempstead

We install caps, crowns, and coatings from Famco, Copperfield, and HeatShield, brands we’ve used for years because they hold up in coastal conditions. We stock common sizes for South Hempstead’s typical flue dimensions, which means faster turnaround and no waiting on a part to ship from the Midwest. For crown coatings and minor repairs, we carry DuraFlex products rated for the temperature swings and moisture exposure these chimneys see. We don’t use builder-grade substitutes. The materials matter when you’re standing behind the work for 90 days in writing.

Common Chimney Cap & Crown Problems We See in South Hempstead Homes

• Crowns that fail early on windward faces. South Hempstead’s exposure to salt-laden Atlantic air accelerates mortar joint erosion and brick spalling beyond what inland communities experience. The windward side of your chimney crown takes the brunt of it, often deteriorating years faster than the leeward side.
• Cracked clay-tile liners hidden under a rusted cap. The defect is invisible until a camera goes up. Homeowners replace the cap while the real problem, condensation eating the brick from inside an oversized flue, keeps spreading.
• Oil-to-gas conversions with no flue resizing. A cold, oversized masonry flue condenses flue gases into corrosive moisture. The crown cracks. The mortar spalls. A new cap can’t fix a draft problem caused by a stack that was never downsized to match the appliance.
• Freeze-thaw damage in pre-1960 brick. South Hempstead’s winter cycles are relentless, not severe, but they drive water into existing mortar cracks and widen them season after season. A crown that sheds water everywhere else fails here faster.
