Why Premier Chimney Cleaning Connecticut Is Old Bethpage’s Preferred Chimney Cap & Crown Company
Eight years, one specialty. That’s the difference when Anthony Perez arrives at your door in ZIP 11804. We’ve built our reputation across Long Island on chimney work only — not gutters, not roofing, not handyman sidework. Over 800 homeowners have reviewed us, and that 4.7-star average reflects the kind of accountability that comes from having the same person own the business and swing the tools.
Old Bethpage isn’t a quick exit off the parkway for us. We know the 1950s–1970s housing stock here — the Cape Cods near the Old Bethpage Village Restoration, the split-levels lining Haypath Road, the ranch homes tucked between Round Swamp Road and Plainview Road. These chimneys were built for oil-fired boilers, not modern inserts, and that matters when you’re sizing a cap or diagnosing crown failure.
Our response time to Old Bethpage is typically same-day or next-day during the heating season. We carry Gelco and DuraFlex multi-flue caps in common sizes, plus HeatShield crown coating materials, so we’re not ordering parts after we arrive. One trip. That’s the standard.
Our Chimney Cap & Crown Services in Old Bethpage
Multi-Flue Cap Installation
Old Bethpage’s 1950s–1960s oil-boiler chimneys feature oversized 8×8-inch terracotta flues that, when capped without proper sizing, trap moisture and accelerate crown damage unlike standard flues found in newer developments. A standard big-box cap won’t seat properly on these larger flue openings, leaving gaps that funnel rainwater directly onto the crown. We fabricate and install custom multi-flue caps — often DuraFlex or Gelco units — that cover the full chimney top while allowing proper draft for whatever appliance currently vents through the system. On a 1962 split-level on Haypath Road, we replaced a cracked concrete crown and installed a custom multi-flue DuraFlex cap to seal an oversized oil-boiler flue that had never been relined after a gas insert conversion; the original crown’s freeze-thaw erosion was letting water pool around the terracotta tiles, and our one-trip fix eliminated chimney leaks that had persisted for two seasons.
Crown Repair
The crown is your chimney’s umbrella — a concrete slab that sheds water away from the flue walls. In Old Bethpage, decades of Nassau County freeze-thaw cycles have eroded these slabs, especially on homes built during the 1952–1972 suburban buildout. We remove deteriorated concrete, reform the crown with proper slope and drip edge, and cure it to manufacturer spec. For oil-boiler chimneys with multiple flue openings, we pay particular attention to the saddle — the raised concrete section between flues — since this is where water first pools and cracks propagate.
Crown Coating
Not every cracked crown needs full replacement. If the concrete substrate is sound but the surface has weathered, we apply HeatShield crown coating — a specialized refractory compound that seals hairline cracks and restores the protective slope. This is often the right call for Old Bethpage split-levels where the crown damage is recent and localized. But here’s the catch: improper crown coating on aged mortar joints traps moisture, causing spalling within one winter. Anthony evaluates the underlying concrete before recommending coating versus rebuild. We’ve seen too many quick coatings fail because the technician skipped this step.
Cap Replacement
Galvanized caps rust. Cheap stainless warps. In Old Bethpage’s inland climate — spared salt spray but still hammered by nor’easters — we install Olympia Chimney and Famco caps rated for the actual conditions. When we’re called to replace a cap, we always inspect the flue sizing against the current appliance. Real-estate-transaction rushed cap replacements often skip flue sizing adjustments, leading to condensation damage that shows up on the next inspection.

Fast turnaround matters when water’s already getting in.
Common Chimney Cap & Crown Problems We See in Old Bethpage Homes
- Oversized terracotta flues understocked with standard caps allow rainwater infiltration. The 8×8-inch flues common in Old Bethpage’s 1960s ranches don’t match today’s standard cap inventory. Homeowners buy what’s available, install it poorly, and water finds the gap. Within two seasons, the crown shows freeze-thaw cracking.
- Improper crown coating on aged mortar joints traps moisture, causing spalling within one winter. We’ve peeled back “fixed” crowns in ZIP 11804 where the coating looked fine but the concrete underneath had turned to gravel. The coating held water in instead of keeping it out.
- Real-estate-transaction rushed cap replacements skip flue sizing adjustments. Sellers need a quick fix to clear inspection. Buyers inherit a cap that doesn’t vent properly for their gas insert or stove. Six months later, we’re back to do it correctly.
- Abandoned oil-boiler flue openings left unsealed during conversions. When Old Bethpage homeowners switch to gas or add a wood insert, the original large flue often gets capped without proper sealing. Cold air, moisture, and even small animals enter the dormant flue, degrading the shared crown from the inside out.

FAQs — Chimney Cap & Crown in Old Bethpage
Your chimney was built with an 8×8-inch terracotta flue sized for an oil-fired boiler, and standard caps are designed for smaller, modern flue dimensions. A custom multi-flue cap seals the larger opening while accommodating any current appliance conversion — gas insert, wood stove, or remaining boiler — without the gaps that let water pool on your crown. Call (833) 719-7193 and we’ll measure your flue configuration during a free estimate.
Yes, if the concrete substrate is sound, we can clean, prep, and apply HeatShield crown coating or perform partial rebuild in a single visit; full crown rebuilds requiring formwork and extended cure time may need a return trip for removal of forms. We stock common materials and assess substrate condition on arrival, so most Old Bethpage crown repairs don’t wait on parts. Call (833) 719-7193 to schedule before the next freeze-thaw cycle widens those cracks.
Yes, pre-sale chimney certifications are a significant share of our Old Bethpage work because Nassau County home inspectors routinely flag oversized oil-boiler flues that were never relined for newer appliances. We document flue sizing, cap installation, and crown condition to satisfy inspection contingencies, and we prioritize these jobs to meet closing timelines. Call (833) 719-7193 — we understand the urgency of a pending sale.
Crown coating is a surface sealant applied when the underlying concrete is structurally sound — suitable for recent weathering with no deep cracks or spalling; full crown repair removes deteriorated concrete and recasts the entire protective slab, necessary when freeze-thaw damage has compromised the crown’s structural integrity. In Old Bethpage’s 50–70-year-old chimneys, we more often recommend full repair because coating alone traps moisture in aged, porous concrete. Anthony evaluates this on-site during your free estimate — call (833) 719-7193.
Yes, we routinely seal or redirect abandoned flue openings as part of cap and crown work, especially on Old Bethpage homes that have converted from oil to gas or added wood inserts without properly decommissioning the original large flue. This prevents cold air infiltration, moisture accumulation, and animal entry that degrade your chimney from the inside. The specific approach depends on your current venting configuration — call (833) 719-7193 for a free evaluation.
