Call (866) 580-4069

We’ve been driving to Clayton since the early 1980s, back when Route 47 was the main corridor south from Glassboro and most of these streets were still lined with original worker housing from the glassworks days. Our technicians know the difference between a cottage on Jackson Street built in 1912 and a post-war frame on Delsea Drive, and they know what kind of chimney each one has before they step out of the truck. That’s not guesswork. That’s 42 years of showing up where we said we would.

Call (866) 580-4069 anytime. A live person answers, even at midnight on a Sunday.

Custom Cap Fabrication for Oversized and Abandoned Flues

Clayton’s historic glass-worker cottages often have oversized square clay tile flues originally built for coal furnaces, which now require custom multi-flue caps or oversized crown repairs to seal abandoned flue openings and prevent moisture intrusion. A standard 8-inch round cap won’t cover a 12×12 square flue, and it certainly won’t seal a partially abandoned dual-flue system where one side vents a gas insert and the other sits open to the weather.

We fabricate custom caps from Copperfield copper and galvanized steel to fit these odd dimensions. On a Jackson Street cottage built in 1912, we found the original clay tile crown had spalled from years of freeze-thaw; the homeowner had a gas insert venting into one corner of an oversized 12×12 flue. We installed a custom fabricated copper multi-flue cap from Copperfield to seal the abandoned portion and applied a HeatShield crown coating to prevent further water damage. The job took four hours. She’s had no water in the firebox since.

Crown Repair and Rebuild

Gloucester County’s inner coastal plain delivers cold but highly variable winters with repeated freeze-thaw cycles that steadily erode mortar joints in the area’s aging brick chimneys. Seasonal humidity from surrounding farmland and wetlands accelerates moisture infiltration between heating seasons, driving spalling and efflorescence on chimneys that otherwise appear structurally sound.

We assess whether your crown needs a targeted repair, a full pour, or a coating system. Small cracks get cut, sealed, and coated. Severely spalled crowns get formed and poured with high-strength concrete sloped to shed water. Every repair is photographed before and after.

Multi-Flue Cap Installation

When a Clayton homeowner adds a wood-burning stove to one of these oversized flues, the negative draft and creosote accumulation risk spikes sharply, a failure mode tied directly to the borough’s industrial-era building stock. A multi-flue cap separates active and inactive flues, maintains proper draft pressure, and keeps rain and animals out of the open portion. We size these on-site and install them with stainless steel hardware that won’t corrode in Clayton’s humid summers.

Crown Coating with HeatShield

For crowns with surface cracking but sound structure, we apply HeatShield’s crown coating system. This isn’t paint. It’s a flexible, breathable membrane that bridges hairline cracks and sheds water while allowing trapped moisture to escape. In Clayton’s climate, where freeze-thaw can turn a minor crack into a major spall in two winters, this preventive treatment often extends crown life by a decade.

Common Chimney Cap & Crown Problems We See in Clayton Homes

• Oversized square clay flues from coal-era conversions cause poor draft and moisture accumulation, leading to crown cracking and spalling. The original flue was sized for a coal furnace that threw tremendous heat up the stack. Your gas insert vents a fraction of that volume. The oversized flue cools too fast, condensation forms on the crown surface, and freeze-thaw opens cracks that let more water in.
• Partial flue abandonment without proper capping creates open joints where water seeps in and deteriorates mortar during freeze-thaw cycles. We see this on homes where the basement furnace was converted to direct-vent but the old flue was left open at the top. Rain goes straight down, hits the smoke shelf, and saturates the masonry from inside.
• Adding wood stoves to oversized flues increases creosote buildup and corrosion risk, accelerating crown decay. The draft is wrong, the flue gas moves too slowly, and creosote condenses on the crown underside where you can’t see it until the damage is done.
• Efflorescence and spalling on crowns that look fine from the ground. Clayton’s humidity and clay soil hold moisture against foundations and chimney bases. By the time you see white staining on the brick, the crown has already been saturated for multiple seasons.
