Fast, Reliable Chimney Cap & Crown Across Hicksville
Chimney cap and crown repair in Hicksville typically runs $380–$1,850 depending on whether you’re sealing hairline cracks or rebuilding a settled crown, and most jobs on the 11801 and 11819 side of town are completed same-day. If your chimney crown is cracked or your cap is missing entirely, water is getting into your flue right now — and in Hicksville’s climate, that damage compounds fast.
We’ve been working on Hicksville chimneys for 17 years, from the original post-war ranches along North Broadway to the Cape Cods tucked into Clearview Village. Robert Garcia, our owner and lead technician, still climbs every roof himself. We know the 1954-built chimney with its single-wythe brick and clay tile liner because we’ve repaired hundreds just like it. Call (866) 884-9512 for a free estimate — we’ll get to your Hicksville home fast, whether you’re off Hempstead Turnpike or down near Newbridge Road.
Why Apex Chimney Cleaning Greater New York Is Hicksville’s Preferred Chimney Cap & Crown Company
Hicksville homeowners don’t hire us because we’re the cheapest option on Long Island. They hire us because Robert Garcia shows up — not a subcontractor, not a rotating crew, but the owner who has 17 years of chimney-only experience and 1,096 verified reviews averaging 4.7 stars. When you’re trusting someone on your roof to diagnose why your 1962 chimney crown is spalling, that accountability matters.
Our response time to Hicksville is typically same-day or next-day, especially for the neighborhoods clustered near the intersection of North Broadway and Newbridge Road where we route multiple calls weekly. We’ve built a local reputation by recognizing what other companies miss: the specific damage pattern caused by Hicksville’s oil-to-gas conversion era. A technician who doesn’t understand carbonic acid condensation inside an oversized flue will sell you a crown coating when you actually need a liner retrofit too. Robert handles it himself — from inspection to material selection to final installation.
Our Chimney Cap & Crown team carries professional-grade materials from DuraFlex, Gelco, and Copperfield on every truck, so we’re not ordering parts after we leave your driveway. That means faster turnaround for Hicksville homes and repairs that last.
Our Chimney Cap & Crown Services in Hicksville
Cap Installation
A proper chimney cap in Hicksville isn’t decorative — it’s your first defense against the salt-laden air rolling in from Long Island Sound and the Atlantic. We install stainless steel and copper caps sized to your exact flue, critical for the unusual flue dimensions found in post-war tract homes. A standard big-box cap won’t seat correctly on a 1950s clay tile liner that’s already spalled at the edges. We measure, we fabricate or specify, and we secure it with proper mounting that won’t lift in a nor’easter.
Cap Replacement
Replacement caps are our most common Hicksville call. The original cap — if there ever was one — has rusted through, blown off, or was never properly sized for a gas-converted flue. In Woodbury Oaks at Woodbury, we regularly find chimneys that have been open to the elements for years, with birds nesting and water pooling on deteriorated crowns beneath. We remove the failed cap, assess the crown condition underneath, and install a replacement that actually fits your flue and appliance type.
Crown Repair
Crown repair is where Hicksville’s housing stock gets specific. The original crown on your 1947–1965 chimney was poured concrete or mortar mix, often too thin and without proper overhang or drip edge. Decades of freeze-thaw cycles — Nassau County sees dozens every winter — have cracked it, and salt air has eroded the exposed edges. We cut out the damaged sections, rebuild with proper crown mix formulated for thermal expansion, and shape it to shed water away from your brick. For crowns that have settled with the chimney structure, we address the underlying alignment so the repair isn’t temporary.
Crown Coating
Crown coating is our most cost-effective option for Hicksville homeowners with hairline cracks and surface spalling but structurally sound crowns. We use professional-grade flexible coatings — HeatShield-compatible systems among them — that bridge small cracks and create a waterproof membrane. This isn’t paint. It’s a specialized cementitious or elastomeric application that flexes with temperature swings. For a 1959 Cape Cod in Clearview Village with minor cracking, crown coating can add 10–15 years of service life at roughly half the cost of rebuild. Robert will tell you honestly if your crown is a coating candidate or if the damage has gone too deep.
Custom Cap
Hicksville’s post-war chimneys were built fast and to similar specs, but that doesn’t mean they’re identical. We’ve measured flues in Birchwood at Jericho that are 9×13 inches, 8×12, and irregular due to liner spalling. Off-the-shelf caps won’t seal. We fabricate custom caps in stainless or copper, with proper screening for spark protection and animal exclusion, sized to your actual flue opening — not a standard chart.
Multi-Flue Cap
For Hicksville homes with multiple fireplaces or a fireplace plus furnace venting through one chimney structure, a multi-flue cap protects the entire crown surface. We see these on larger split-levels near Dwight David Eisenhower Park. The key is proper height and screening on each flue, with a skirt that sheds water beyond the crown edge.

Common Chimney Cap & Crown Problems We See in Hicksville Homes
- Salt-air mortar erosion. Nassau County’s position between Long Island Sound and the Atlantic means persistent salt-laden air attacks exterior mortar joints. We’ve repointed chimney crowns in Hicksville where the mortar has receded a half-inch or more, creating channels that direct water straight into the brick structure.
- Freeze-thaw crown cracking. Long Island winters deliver repeated freeze-thaw cycles. Water enters hairline cracks in the crown, expands when frozen, and widens those cracks exponentially. By spring, a 1/16-inch crack can be a 1/4-inch gap with spalled concrete beneath.
- Settling misalignment from tract-built foundations. Hicksville’s rapid post-war construction often meant minimal foundation preparation. We’ve found original brick chimneys settled 1–2 inches, tilting the crown away from the flue and creating a gap that admits water and combustion gases. The crown can’t be repaired without addressing this structural shift.
- Acidic condensation from oil-to-gas conversions. This is the Hicksville signature failure. Gas appliances vent cooler, wetter exhaust into chimneys sized for hot oil exhaust. The oversized flue cools the vapor prematurely, condensing carbonic acid inside the clay tile liner. The liner spalls from within. If the crown cap is missing or leaking, rainwater compounds the corrosion. We’ve opened flues in Hicksville where the tile has eroded to half its original thickness.

FAQs — Chimney Cap & Crown in Hicksville
The clay tile liner in your 1947–1965 chimney was sized for the high-temperature exhaust of an oil furnace. Gas exhaust is cooler and wetter. In the oversized flue, it cools too fast, condenses into carbonic acid, and eats the tile from the inside out. A DuraFlex stainless steel liner properly sizes the flue for gas appliances and resists that acid attack. Without it, you’re repairing crowns and caps on a chimney whose liner is actively disintegrating. Call (866) 884-9512 — we’ll inspect yours and show you exactly what we find.
Hairline cracks in a crown that’s otherwise structurally sound and properly sloped are ideal candidates for crown coating. We clean the surface, fill cracks, and apply a flexible waterproof membrane that bridges thermal movement. If the crown is thin (under 2 inches), improperly sloped toward the flue instead of away, or the cracks have widened past 1/8 inch, replacement is the honest recommendation. Robert will measure and show you the difference. Estimates are free — call (866) 884-9512.
Yes. We fabricate and install custom stainless steel and copper caps measured to your actual flue opening, not a standard catalog size. Many Hicksville chimneys have spalled or irregular tile edges that make off-the-shelf caps impossible to seal. We account for that. Call (866) 884-9512 to schedule a measurement.
On roughly half the Woodbury Oaks at Woodbury inspections we perform, the original cap is either missing entirely, rusted through, or a generic hardware-store size that doesn’t cover the flue properly. These chimneys were built without caps in many cases, or with galvanized steel that failed decades ago. An open flue in this neighborhood means direct water entry onto a crown that’s already facing salt-air and freeze-thaw stress. Call (866) 884-9512 for a free inspection — we’ll check yours even if you’re not sure it’s there.
Crown coating costs roughly 40–60% less than replacement and extends service life 10–15 years when the underlying crown is thick enough and properly sloped. In Hicksville’s 11801 and 11819 ZIP codes, where many crowns were poured adequately but have developed surface cracking, coating is the pragmatic choice. Replacement becomes necessary when the crown has settled, thinned below 2 inches, or the cracks penetrate to the brick below. Robert evaluates each crown honestly — we’ve recommended replacement when coating would fail, and coating when replacement would waste your money. Call (866) 884-9512 for an assessment.
