Why Hearthstone Chimney Co. of New York City Is Paterson’s Preferred Chimney Cap & Crown Company
We’ve been crossing the river to Paterson since 1984, long enough to know the difference between a Sandy Hill tenement chimney chase and a North Haledon split-level. That matters when your cap job requires navigating a third-floor roof through a four-foot alley with no driveway.
Our technicians are background-checked, uniformed, and carry the full range of DuraFlex, Gelco, and Copperfield caps and crown coating materials on the truck. Most Paterson jobs finish in a single visit because we don’t make two trips for parts.
The 90-Day Done Right Promise governs every cap and crown job we do in Paterson: in writing, no arguing. If it’s not right, we come back. We’ve operated this way for over four decades because we plan to be serving Paterson homeowners for decades more.
Calls are answered by a live person, not a queue, not an app. That’s every hour, every day, including Sunday evenings when you notice water dripping through the flue after a Passaic Valley storm.
Our Chimney Cap & Crown Services in Paterson
Multi-Flue Cap Installation & Replacement
Paterson’s 2-to-4-family brick row houses were built with single chimney chases serving multiple units, and too often we find one flue capped while another vents raw into the chase. In the 4th Ward, shared chimney chases in 1880s brick row houses often vent multiple units with mismatched oil-to-gas conversions, and we routinely find missing or corroded multi-flue caps that allow rain and debris to accelerate spalling in the oversized coal-era flues. A proper multi-flue cap from Gelco or DuraFlex seals the entire chase, stops cross-venting between units, and meets NJ UCC requirements. We measure on-site and fabricate to fit your exact chase dimensions.

Custom Cap Fabrication
Standard caps don’t fit Paterson’s irregular flue spacing. On a recent cap replacement job on Madison Avenue in the Sandy Hill neighborhood, we accessed a third-floor townhome roof through a tight rear alley to find a multi-flue terra-cotta crown spalled from decades of freeze-thaw. We installed a DuraFlex custom cap with a rolling-code remote opener for the property owner, restoring safe venting and preventing backdrafts from the adjacent unit’s uncapped flue. Custom work costs more upfront. It costs less than replacing water-damaged masonry.

Crown Repair
The concrete crown is your chimney’s umbrella. In Paterson, crowns crack faster than in surrounding towns because the Passaic River valley traps cold, damp air against masonry that was never designed for modern low-temperature venting. Coal-era mortar joints under poorly crowned chimneys spall rapidly from acidic condensate from modern oil/gas appliances, common in oversized 4th Ward flues. We remove deteriorated crown material, pour new concrete with proper slope and drip edge, and seal with professional-grade crown coating.

Crown Coating
For crowns with surface cracking but sound structure, crown coating extends service life five to ten years. We use HeatShield and Copperfield elastomeric formulations that flex with freeze-thaw cycling. Application takes a few hours, cures overnight, and stops the water intrusion that destroys mortar from the top down. In Paterson’s five-month heating season, that protection matters.

Common Chimney Cap & Crown Problems We See in Paterson Homes
- Shared multi-unit flues missing individual caps cause cross-venting and dangerous backdrafts between separately owned units in Paterson’s tenements. We find this repeatedly in 07504 and 07505 zip codes, where unlicensed secondary flue connections violate NJ UCC and create liability for every owner on the chase.
- Coal-era mortar joints under poorly crowned chimneys spall rapidly from acidic condensate from modern oil/gas appliances, common in oversized 4th Ward flues. The flue was built for 1,200-degree coal exhaust, not 300-degree gas condensate. The chemistry eats old mortar.
- Alley-access roofs in Eastside row houses delay inspections, leaving corroded crown coatings unchecked until water damage spreads through the masonry. Property owners put off the call because scheduling roof access feels complicated. It isn’t. We handle the logistics.
- Freeze-thaw damage accelerates faster in Paterson’s river-valley microclimate than in drier suburban towns like Hawthorne or North Haledon. Water enters hairline cracks, expands overnight at twenty degrees, and widens the gap by spring. Annual inspection catches this before rebuild territory.

FAQs - Chimney Cap & Crown in Paterson
Yes, each flue needs its own termination cap, and the entire chase needs a proper multi-flue cap or sealed chase cover to prevent cross-venting. In Paterson’s densest wards, a single shared chimney chase commonly vents two or three separately owned or rented units with mismatched appliances added over decades by different landlords - technicians routinely discover unlicensed secondary flue connections and cross-venting between units, a NJ UCC code violation that creates both liability and dangerous backdraft risk unique to this style of urban multi-family construction. Our Chimney Cap & Crown team will document what we find with photos and explain your options in plain English. Call (855) 950-3861 for a free inspection.
We can often reach Paterson properties same day for emergency cap replacements, especially in the 07504, 07505, 07509, and 07510 zip codes where our crews work regularly. After a Passaic Valley windstorm or ice event, missing or damaged caps expose flues to immediate water intrusion. A live person answers our phones 24/7, and we prioritize calls where the flue is open to weather. Call (855) 950-3861 and we’ll give you a realistic arrival window.
Yes, we fabricate custom caps to exact field measurements, and Paterson’s 1920s tenement chases with irregular flue spacing are exactly the situation custom caps solve. Standard box-store caps rarely fit these configurations. We measure flue spacing, chase dimensions, and clearance requirements on-site, then build a DuraFlex or Copperfield custom cap that seals properly and meets code. Most custom jobs complete in one visit. Call (855) 950-3861 to schedule measurement.
Three factors converge in Paterson: oversized coal-era flues venting cool modern exhaust, the Passaic River valley’s damp microclimate, and aggressive freeze-thaw cycling that suburban towns like Hawthorne experience less intensely. The combination saturates old mortar, then fractures it when temperatures drop overnight. Crown coating and proper cap installation interrupt this cycle. We’ve rebuilt more crowns in Paterson’s 4th Ward than in any nearby town precisely because of this local failure pattern. Call (855) 950-3861 if you see crown cracking.
We coordinate access details when you schedule, and our technicians carry equipment for tight entries common in Eastside’s alley-loaded row houses. Many Paterson properties have gated rear alleys, narrow passages between buildings, or basement-level utility access. We’ll ask the right questions when you call so there are no surprises on arrival. If you have a gate code or neighbor contact, we’ll note it. Call (855) 950-3861 and we’ll sort the logistics with you.
