Call (855) 950-3861

We’ve worked on enough chimneys in Union City to know the building stock by heart. The 3-to-6-story brick tenements along Bergenline Avenue, Summit Avenue, and the side streets between them were built between roughly 1890 and 1940, and they share a problem you won’t find in newer New Jersey suburbs: single exterior chimney stacks serving multiple flues, often with mismatched caps, deteriorated crowns, and flues that were never properly resized when oil burners became gas furnaces decades ago. That density and age create cap and crown challenges specific to ZIP 07087. We bring custom-fabricated caps, professional-grade crown coatings, and the patience to work in tight alley-load conditions where ladder access is cramped and every repair affects neighboring units.

Why Hearthstone Chimney Co. of New York City Is Union City’s Preferred Chimney Cap & Crown Company

We’ve been answering the phone with a live person for over 42 years, and that hasn’t changed. When a Union City homeowner calls at 6 a.m. because water is pouring through the ceiling around their chimney breast, someone picks up. No voicemail. No callback queue.

Our technicians are background-checked and uniformed, and they carry the materials to complete most jobs in a single visit. That’s critical in Union City, where parking near a Summit Avenue row house means feeding a meter or coordinating with a neighbor, and where no one wants a second appointment if it can be avoided.

We document every inspection with photos and a plain-English verdict. In Union City’s shared-stack buildings, that documentation matters. When three households depend on one chimney, everyone needs to see what we found and understand why the repair protects them all.

Every job is backed by our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork to dig up. No arguing.

Our Chimney Cap & Crown Services in Union City

Multi-Flue Cap Installation & Replacement

Union City’s defining chimney problem is the shared stack. A single masonry chase on a four-unit tenement might serve a basement boiler flue, a second-floor fireplace, and a third flue capped sometime in the 1980s and forgotten. One missing or rusted cap exposes the entire chase to rain, debris, and the accelerated spalling that destroys common brickwork.

We fabricate and install multi-flue caps sized to cover all outlets on a shared stack while maintaining proper draft for each. On a recent job near 32nd Street and New York Avenue, we replaced a corroded galvanized cap that had collapsed into one flue, threatening to block the boiler vent for two units below. The new cap was measured on-site, fabricated from stainless steel with integrated spark arrestor, and installed same-day.

Crown Repair & HeatShield Coating

The crown is the concrete or mortar slab sealing the chimney top below the cap. In Union City, crowns take a beating. The city sits atop the Hudson Palisades ridge at roughly 200 feet elevation, fully exposed to wind funneling off the Hudson River from the east. Northeast storms drive rain directly into hairline cracks, which freeze, expand, and split the crown deeper each winter.

We repair crowns by removing deteriorated material, rebuilding with proper slope and overhang, and sealing with HeatShield crown coating - a professional-grade elastomeric compound that remains flexible through freeze-thaw cycles. For crowns with minor cracking, coating alone can add years of service. For crowns that have failed structurally, we rebuild and then coat. The number on the estimate is the number on the invoice.

Custom Cap Fabrication

Standard box-store caps don’t fit Union City’s irregular flue configurations. An oil-to-gas conversion often left an 8×8-inch clay tile flue serving a furnace that needs only a 5-inch liner. The resulting oversize opening creates downdraft problems and allows rain to pool. A stock cap sits crooked, gaps open, or the homeowner resorts to improvised blockages that create carbon monoxide hazards.

We measure each flue opening, account for liner protrusion or absence, and specify custom caps from Copperfield and Gelco when standard sizes won’t seal properly. The cap gets fabricated, delivered, and installed - usually within a week for Union City customers.

Cap Replacement on Single-Flue & Fireplace Chimneys

Not every Union City building has the shared-stack problem. The standalone fireplace chimneys in some of the area’s converted brownstones and owner-occupied row houses need straightforward cap replacement when galvanized steel rusts through or mesh siding blows off in a Palisades wind gust. We stock common sizes and can often replace a failed cap during the same visit as an inspection.

Trusted Brands We Service in Union City

We work exclusively with professional-grade materials - no builder-grade substitutes that fail in two seasons. For cap and crown work in Union City, we regularly specify Copperfield stainless steel caps for durability in salt-air exposure from the Hudson, Gelco custom-fabricated solutions for irregular multi-flue configurations, and HeatShield crown coating for flexible, long-lasting waterproofing. We stock common sizes and maintain supplier relationships that keep turnaround short, even for custom orders. When you’re trying to get a leaking chimney sealed before the next northeast storm, that matters.

Common Chimney Cap & Crown Problems We See in Union City Homes

• Shared multi-flue stacks without individual caps. A missing or damaged cap on one flue allows rain and debris into the entire chimney chase, causing spalling of common bricks and jeopardizing adjacent flues. We see this constantly in the older tenement stock near Bergenline Avenue, where one owner’s neglect becomes three owners’ emergency.
• Oversized flues from oil-to-gas conversion. Original 8×8 tile flues now serving efficient gas furnaces create draft issues. A poorly fitted cap exacerbates downdraft and moisture pooling, accelerating crown cracks. The fix is a properly sized liner plus a cap engineered for the actual flue opening.
• Crown mortar deterioration from wind-driven rain off the Hudson Palisades. Northeast storms blast unsealed crowns, leading to deep mortar cracks that permit water to freeze and expand, further splitting the crown and threatening the entire stack. The exposed ridge elevation makes this worse in Union City than in inland Hudson County towns.
• Improvised or missing caps on abandoned flues. In shared-stack buildings, one flue often gets capped with sheet metal and roofing tar when a unit converts to electric heat. That temporary seal cracks, lifts, or blows off, creating an open hole that funnels water directly onto the common crown.
