We’ve been driving to North Massapequa for over 42 years, and by now we know these streets the way a sweep knows a flue. The Cape Cods off Hicksville Road, the ranches near the Southern State, the split-levels up by Jerusalem Avenue - they all share the same story. Post-WWII brick chimneys built for oil heat, decades of conversions, and salt air coming off the Great South Bay that eats mortar faster than you’d believe. Our Chimney Cap & Crown team doesn’t guess at what’s wrong. We run a camera, show you the footage, and tell you straight whether you need a cap, a crown repair, or something deeper. Dispatch is coordinated from our New York City office, but our crews live and work on Long Island. We’ll be there when we say.

Our Chimney Cap & Crown Services in North Massapequa

Custom Cap Installation

North Massapequa’s mid-century masonry chimneys were never standardized. Dual-flue stacks serving an abandoned fireplace and a converted gas furnace, odd flue spacing, deteriorated terra cotta - a box-store cap won’t fit and won’t seal. We measure on-site, fabricate a custom stainless or copper cap to your chimney’s exact dimensions, and install it with proper clearances and secure mounting. On a Cape Cod off Hicksville Road, our tech found the original dual-flue chimney still serving an abandoned wood fireplace and a gas furnace on the oil-era tile - mortar joints in the crown eroded to a sand-and-grit consistency, and the flue tile spalling internally from acidic condensate the furnace was producing. After a Level 2 camera inspection the homeowner watched on our monitor, we installed a custom multi-flue stainless cap with a Gelco crown coating over the repaired crown rather than a new masonry crown, and replaced the failed cap that had been letting water into the smoke chamber for years.

Cap Replacement

That rusted galvanized cap from 1987 is doing more harm than good. In North Massapequa, where South Shore salt air accelerates corrosion, a compromised cap lets rain and salt reach the flue liner directly. We remove the old unit, inspect the flue and crown beneath it, and install a replacement that actually fits. If the underlying liner is the real problem - oversized oil-era tile venting a gas furnace - we’ll show you the camera footage and explain why a cap alone won’t fix what’s rotting from inside.

Crown Repair

The crown is the concrete or mortar wash that seals the chimney top between the flue tiles and the brick edge. On North Massapequa’s 60-70-year-old chimneys, original crowns have endured decades of coastal freeze-thaw cycles and salt spray. Cracks widen every winter. Water penetrates, freezes, expands, and repeats. We grind out deteriorated material, rebuild with proper slope and overhang, and seal with a waterproof crown coating. Done right - and we stand behind it.

Crown Coating

Not every cracked crown needs full rebuild. For crowns with sound structural integrity but surface deterioration, we apply a professional-grade flexible crown coating - Gelco and HeatShield products formulated for marine-exposure climates like the South Shore. This seals existing hairline cracks, prevents new water intrusion, and extends service life significantly. We’ll tell you honestly whether coating is sufficient or whether the crown is too far gone. Photos you can see, a plain-English verdict.

Multi-Flue Cap

Many North Massapequa Cape Cods have dual-flue chimneys - one for the original oil burner, one for the fireplace. After conversion, one flue may be abandoned, both may be active, or a gas appliance may vent into a flue never designed for it. A multi-flue cap covers the entire chimney top with proper screening, rain protection, and ventilation for each flue. We size and install these precisely, accounting for draft requirements and clearances that vary with appliance type.

Trusted Brands We Service in North Massapequa

We work exclusively with professional-grade materials: Gelco stainless caps and crown coatings, Olympia Chimney multi-flue systems, and Famco custom fabrication components. These are the brands that other sweeps use on their own homes. We stock common sizes and configurations for fast turnaround on North Massapequa calls, and custom-order what we don’t carry. No builder-grade substitutes, no waiting three weeks for a part that doesn’t quite fit.

Common Chimney Cap & Crown Problems We See in North Massapequa Homes

• Original terra cotta or poured crown cracked by coastal freeze-thaw. Decades of salt-laden marine air and winter nor’easters have eroded mortar joints to sand-and-grit consistency. Meltwater runs down the flue liner into the smoke chamber and firebox, accelerating deterioration from the top down.
• Lightweight or missing cap on a multi-flue stack. Rain and South Shore salt air reach the oversized oil-era liner directly, speeding up spalling of interior tile that was already compromised by acidic condensate from a converted gas appliance.
• Abandoned oil flue capped with a flat plate and no draft. A prior contractor or homeowner sealed the flue to “keep water out,” but trapped acidic condensate from the gas appliance against the liner. It rots silently from inside while the furnace “seems fine.” We find this on camera inspections regularly.
• Improper cap sizing after appliance conversion. A cap installed for oil-heat draft requirements chokes a modern gas appliance, or a cap sized for a single flue leaves a dual-flue stack half-exposed. Both cause condensation problems that destroy liners and crowns.
