Our Chimney Cap & Crown Services in East Hanover

Custom Cap Fabrication

East Hanover’s oil-to-gas conversion history created a generation of chimneys that don’t fit catalog parts. On Ridgedale Avenue and adjacent streets, many double-wythe chimneys have a B-vent gas liner inserted without capping the surrounding open flue tile, creating a year-round debris trap and chronic cold-air backdraft. A stock cap won’t seal that. We measure on site and fabricate custom caps from stainless or copper that cover the full chimney top, seal unused flues, and stop the downdraft problems that plague these conversions.

On a ranch off Ridgedale Avenue, we found a double-wythe chimney where a previous contractor slid in a DuraFlex gas liner but left the original 8×12 clay tile unsealed. A layer of leaves and soot had filled the void, causing persistent downdraft and cap corrosion. We installed a custom multi-flue cap, sealed the unused tile, and coated the crown-fixing it all in one trip.

Multi-Flue Cap Installation

Split-levels throughout East Hanover’s 07936 zip often have single chimneys serving multiple appliances: a fireplace flue, a furnace flue, sometimes a former oil-boiler flue now abandoned. Each needs its own venting path, but the chimney top is one shared surface. A multi-flue cap from Copperfield or Famco gives each flue independent protection while shielding the entire crown from Morris County’s wind-driven rain. The moderate-elevation valley here channels cold northwest winds down from the Watchung-area hills, and that rain hits harder than homeowners expect.

Crown Repair

The freeze-thaw cycle in East Hanover is aggressive. Ninety to 110 freeze-thaw events per heating season hammer concrete crowns that were poured 50 to 70 years ago without expansion joints or modern admixtures. Spalling, cracking, and washboard texture are normal on chimneys we inspect in the residential core. We cut out deteriorated concrete, form and pour new crowns with proper slope and drip edges, and seal them for the long haul.

Crown Coating

Not every crown needs replacement. If the concrete is structurally sound but weathered, a professional-grade crown coating extends its life significantly. We use elastomeric formulations that flex with freeze-thaw movement rather than cracking again the next winter. For East Hanover’s 50-70-year-old oil-conversion chimneys, this is often the right middle path between doing nothing and full reconstruction. The coating buys time. Done right, it buys years.

Trusted Brands We Service in East Hanover

We work exclusively with professional-grade materials: DuraFlex for gas liner and cap integration, Famco and Copperfield for cap fabrication and hardware, HeatShield for crown repair systems, and Olympia Chimney for specialty venting components. These are not builder-grade substitutes. We stock common cap sizes and crown coating materials so East Hanover customers aren’t waiting on a parts order while water continues seeping through a cracked crown. The right material for the specific failure mode, installed by a technician who has seen that failure before, is how we complete most jobs in a single visit.

Common Chimney Cap & Crown Problems We See in East Hanover Homes

• Freeze-thaw crown destruction: Heavy freeze-thaw cycles (90-110 per season) cause crowns on 50-70-year-old oil-conversion chimneys to spall and crack, letting moisture into the double-wythe structure. The damage accelerates once water reaches the reinforcing wire, which rusts and expands.
• Unsealed flue tiles from improper conversions: Improper oil-to-gas conversions leave undersized clay-tile flues unlined, accelerating condensation and mortar joint failure in ranch and split-level homes. The open tile becomes a chimney within a chimney, but one that breathes cold air and debris.
• Deferred maintenance on acreage properties: Owners of larger East Hanover parcels often defer repairs until multiple issues accumulate, leading to caps loosened by wind and crowns eroded by years of neglect. By the time we see them, water has often reached the interior wythe.
• Wind-driven rain penetration: The township’s valley position focuses northwest winds and heavy rain on chimney tops. Aging crowns without proper drip edges or overhangs allow water to run directly down the brick face, saturating mortar joints that were never designed for that load.
