Why Apex Chimney Cleaning Greater New York Is Malverne’s Preferred Chimney Cap & Crown Company

We’ve been driving to Malverne for 17 years, and Robert Garcia still handles every cap and crown job personally — not a subcontractor, not a rotating crew. That matters when you’re trusting someone on your roof in a village where nearly every chimney was built during the Long Island suburban boom and has seen decades of salt-air exposure.

Our 1,096 verified customer reviews averaging 4.7 stars include dozens from Malverne homeowners who found us after other companies suggested a cheap cap slap-on that ignored their cracked crown or shared flue problem. Robert’s camera inspection catches what surface-level sweeps miss — crumbled mortar, liner cracks, crown separation — and he’s got the parts on his truck to fix it the same visit when possible.

From Malverne’s south-facing rooflines on Ocean Avenue to the tighter lots near Lakeview Avenue, we know the wind patterns that drive rain into chimneys and the mortar types that fail here. Response time to Malverne is typically same-day or next-day for crown emergencies, and we stock Gelco polymer-modified crown mix and stainless multi-flue caps sized for the village’s older flue configurations.

Our Chimney Cap & Crown Services in Malverne

Cap Installation

New cap installation in Malverne starts around $280–$450 for a standard single-flue stainless unit, but most Malverne jobs need more. The village’s original chimneys were built for oil furnaces, often with a shared flue serving both the furnace and a fireplace. A standard single-flue cap won’t seal that properly. We measure on-site and install multi-flue caps or custom-fabricated units that cover the full chimney top, keeping rain and animals out of both flue openings. For a 1940s Colonial near Hempstead Avenue, we’ll likely recommend a stainless-steel multi-flue cap with an elevated lid for airflow — the salt air here chews through galvanized steel in five to seven years.

Cap Replacement

Cap replacement in Malverne runs $320–$580 when we’re swapping a rusted or wind-damaged unit on an otherwise sound crown. The problem we see most: a homeowner bought a big-box store cap that didn’t account for their shared flue, or the original cap was galvanized steel that corroded through from salt exposure. Robert removes the old cap, inspects the crown beneath for hidden cracks (salt-driven spalling often hides under the cap flange), and installs a properly sized replacement. If the crown’s compromised, we’ll tell you before we bolt anything down — no point in capping a crown that’s disintegrating.

Crown Repair

Crown repair is our most frequent Malverne service, typically $450–$750. The village’s coastal position — roughly three to four miles from the Atlantic and Great South Bay — means salt-laden air accelerates mortar joint erosion and crown spalling faster than you’d see in West Hempstead or North Valley Stream. Nor’easters hitting south-facing rooflines drive rain directly into crown cracks, and once water freezes in those fissures, the crown separates from the brick below. Robert rebuilds crowns with Gelco polymer-modified crown mix, which flexes slightly with freeze-thaw cycles instead of cracking like standard mortar. Last spring we repaired a crown on a 1930s Tudor on Hempstead Avenue where the original clay-tile liner had cracked and the crown was disintegrating from salt-air exposure. We rebuilt the crown with that Gelco mix and installed a stainless-steel multi-flue cap to prevent rain entry and further mortar erosion.

Crown Coating

Crown coating in Malverne costs $280–$420 and buys time when the crown is cracked but structurally sound. We use HeatShield crown coat — a flexible, waterproof membrane that bridges hairline cracks and blocks salt-air penetration. It’s not a permanent fix for a crown that’s already separating from the brick, but for a 1950s Cape Cod on the north side of the village with minor surface spalling, it can extend service life five to seven years. Robert applies it after wire-brushing loose material and priming the surface; the coating cures to a UV-stable finish that won’t chalk or peel like consumer-grade sealers.

Multi-Flue Cap

Multi-flue cap installation in Malverne ranges $480–$890, and it’s what most village chimneys actually need. That shared flue — oil furnace on one side, fireplace on the other, both venting through the same chimney top — requires a cap that covers the entire chimney crown, not just individual flue tiles. We fabricate and install stainless-steel multi-flue caps with screened sides for draft and animal protection, sized to your chimney’s exact dimensions. The alternative — two separate caps crammed onto a shared crown — traps moisture between them and accelerates the very decay you’re trying to prevent.

Custom Cap

Custom cap fabrication in Malverne starts around $650 and goes up based on metal choice and complexity. For homeowners on Ocean Avenue or near Malverne’s historic core who want copper that weathers to a green patina matching their Tudor trim, we work with Copperfield to source and shape the material. Robert measures, sketches, and oversees fabrication — custom means custom, not “close enough.” Lead time is typically one to two weeks, and we install with stainless fasteners and proper counter-flashing to keep salt air from attacking the attachment points.

Trusted Brands We Service in Malverne

We install professional-grade materials from DuraFlex, HeatShield, and Gelco — the same lines commercial chimney contractors use on Long Island. Robert keeps Gelco polymer-modified crown mix and HeatShield crown coat on his truck for Malverne jobs, along with stainless multi-flue caps in common sizes. That stock means no waiting on parts when your crown’s leaking into the flue during a March nor’easter. For custom work, we source through Copperfield. Everything’s sized and installed for the village’s older flue configurations, not whatever’s sitting in a warehouse.

Common Chimney Cap & Crown Problems We See in Malverne Homes

• Salt-air crown spalling. Malverne’s coastal air accelerates mortar joint and crown spalling, requiring more frequent crown repairs than inland towns. We see this on nearly every pre-1960 chimney we inspect — the surface layer of the crown flakes off, exposing the aggregate beneath, and water penetrates the cracks within a season.
• Rain-driven nor’easter damage. Storms hitting south-facing rooflines force water behind flashing, leading to crown-to-brick separation and leaks. After a major storm, we get calls from Malverne homeowners who’ve noticed water stains on their fireplace surround or heard dripping in the flue.
• Hard Portland cement repointing failure. Original flues repointed with overly-hard Portland cement mortar crack and crumble inward, blocking the flue and making cap removal necessary for camera inspection. This is nearly universal in Malverne’s 1920s–1950s housing stock — the sweep often pulls debris that is crumbled mortar, not just creosote.
• Undersized or mismatched caps. Homeowners who’ve converted from oil to gas or added a fireplace insert frequently have chimneys with undersized, unlined, or clay-tile-cracked flues that fail inspection. A standard cap won’t fit or seal properly, and the wrong cap traps moisture against the crown.
