We’ve been working on Paramus chimneys for over 42 years, and we know the borough’s streets well - from the split-level blocks off Midland Avenue to the colonials near Paramus Park and the ranches along Spring Valley Road. Our crews are dispatched from our metro office and carry the inventory to handle same-visit cap and crown work on the mid-century chimneys that dominate this town. When your crown is cracked or your cap is rusted through, water gets into the flue, freeze-thaw cycles widen the damage, and you’re looking at liner or masonry repairs that cost far more than the crown ever would have.

Why Hearthstone Chimney Co. Is Paramus’s Preferred Chimney Cap & Crown Company

Paramus homeowners call us because we document what we find. Every cap and crown job starts with a Level-2 camera inspection - photos you can see, a plain-English verdict - so you know whether you’re looking at a $340 cap replacement or a crown that needs coating before any new hardware goes on. No guessing, no surprises on the bill.

Our reputation here is built on doing the job right and standing behind it. The 90-Day Done Right Promise means if it’s not right, we come back - in writing, no arguing. Background-checked, uniformed technicians arrive when we say they will, and most cap and crown jobs are completed in a single visit with no-hassle upfront pricing.

We also understand what Paramus chimneys actually are. This borough was built out almost entirely during the 1950s-1970s suburban boom alongside Route 4 and Route 17, leaving an unusually dense, same-generation stock of split-level and colonial homes - nearly all with original masonry chimneys now 50-70 years old. These aging flues, built with clay tile liners standard to that era, are simultaneously reaching the end of their serviceable life. That creates a concentrated borough-wide wave of cracked tiles, spalled mortar joints, and deteriorated crowns that no neighboring town faces at quite the same scale or uniformity. We’ve seen it hundreds of times. We know what to look for.

Our Chimney Cap & Crown Services in Paramus

Cap Installation

New cap installation on a Paramus chimney starts with understanding how many flues are in your chase and what they’re venting. A standard single-flue cap works for a fireplace-only flue, but many Paramus split-levels and raised ranches have a shared masonry chase with two flues - one for the fireplace, one for the furnace. We install multi-flue caps with proper height and screening so each flue vents independently. No cross-contamination, no draft problems. We stock Gelco and Famco caps for common flue sizes and can fabricate custom covers for irregular chase dimensions.

Cap Replacement

Paramus’s 60-80 annual freeze-thaw cycles destroy caps faster than almost anywhere in Bergen County. Water gets under the metal, rusts the mounting flange, and the cap lifts or blows off entirely - we’ve found them in front yards on Farview Avenue after winter storms. Replacement isn’t just swapping hardware. We inspect the flue tiles and crown condition beneath the old cap, because installing a new cap on a deteriorated crown is a waste of your money. If the crown is sound, we’ll mount a properly sized replacement with stainless steel fasteners and a storm collar. If it’s not, we’ll tell you before we proceed.

Crown Repair

The crown is the concrete or mortar slab that seals the top of your chimney chase. On Paramus’s 1960s colonials, these were often poured as a single-wythe cap of basic mortar mix with no reinforcement - fine for 1975, failing everywhere now. Bergen County’s freeze-thaw cycle opens hairline cracks, water saturates the masonry below, and the crown crumbles from the underside out. Crown repair means removing the loose material, rebuilding with proper crown mix sloped for drainage, and sealing the perimeter where crown meets brick. For crowns with moderate spalling but solid structure, we often recommend crown coating instead.

Crown Coating

Crown coating is our preferred approach for Paramus chimneys where the crown is cracked and porous but hasn’t fully separated from the chase. We apply a flexible, waterproof membrane - we use HeatShield and Gelco crown coatings - that bridges existing cracks and prevents new water intrusion while allowing the masonry to breathe. This is especially valuable on shared chases where both flues need protection and you want to avoid the cost and mess of full crown demolition. A coated crown with a new multi-flue cap can add 15-20 years of service to a 1960s chimney that would otherwise need rebuild-level work. We warranty the coating and document the before-and-after with photos.

Multi-Flue Cap

Multi-flue caps are essential on Paramus’s shared-chase homes, and they’re the most common cap we install here. A proper multi-flue cap covers the entire chase top with a raised lid, screened sides for draft, and independent venting for each flue. This prevents the cross-contamination problem that’s specific to Paramus’s housing stock - when one home’s appliance exhaust gets pulled into a neighboring flue because the caps are too low or too open. We fabricate and install multi-flue caps with center stacks tall enough to clear turbulent draft off Route 4 and Route 17, and we size them to the actual appliance mix in your home - fireplace plus oil boiler, fireplace plus gas conversion, or dual fireplace.

Custom Cap

Some Paramus chases need more than an off-the-shelf solution. Oversized chases from the 1950s, chases with three or more flues, or chases with irregular angles from previous repairs all benefit from a custom-fabricated cap. We measure on site, fabricate from stainless steel or copper, and install with proper clearances and storm protection. Custom caps cost more upfront but eliminate the gap and leak problems that come from forcing a standard cap onto a non-standard chase. On attached homes along tight streets like those near Paramus High School, a custom cap also reduces the profile and wind load that can tear a poorly fitted cover loose.

Trusted Brands We Service in Paramus

We don’t use builder-grade substitutes. Our Paramus trucks stock professional-grade caps and crown materials from Gelco, Olympia Chimney, and Famco - brands that have proven themselves in Bergen County’s freeze-thaw climate. Gelco’s stainless multi-flue caps handle the wet weather and wind exposure that come with Paramus’s flat Hackensack River valley location. Olympia Chimney’s crown coatings bond reliably to the older mortar mixes common in mid-century construction. Famco’s custom fabrication options let us match odd chase dimensions without field modifications that compromise the seal. Because we carry inventory locally, most Paramus cap and crown jobs need no ordering delay. The part you need is on the truck.

Common Chimney Cap & Crown Problems We See in Paramus Homes

• Shared-stack cross-contamination. Paramus’s mid-century split-levels and colonials were often built with a single masonry chase serving both a fireplace flue and a separate oil-furnace flue, and because so many neighbors on the same block still run different appliances, one home’s furnace can vent into a shared or adjacent stack and push acidic condensate and exhaust into a neighbor’s flue. That shared-stack cross-contamination is a Paramus-specific cap-and-crown problem, not just an older-chimney problem. A standard single-flue cap won’t fix it. You need a multi-flue cap with proper stack height and independent venting, and often crown coating to seal the chase top against pressure differentials.
• Freeze-thaw crown destruction. Original single-wythe crowns on 1950s-70s Paramus homes are cracking from 60-80 annual freeze-thaw cycles, letting water into the shared chase and feeding rust on both flues’ caps. Once the crown is compromised, the cap mounts loosen, the flue tiles spall, and the repair scope multiplies. We catch this early with camera inspection and stop it with crown coating or rebuild before the chase needs structural work.
• Acidic condensate from oil-to-gas conversions. When a neighbor’s oil-to-gas conversion under-temps an oversized masonry flue, the resulting acidic condensate eats the cap’s metal and the crown’s mortar, so a standard cap replacement fails again within a season or two. We see this constantly in Paramus blocks where conversions are happening in sequence. The fix is a properly sized cap for the new appliance’s venting requirements, plus crown coating to protect the masonry from the acidic moisture that the old flue never produced.
• Wind-driven draft failure on exposed chases. On attached and closely spaced Paramus properties, a low or undersized cap can’t handle the turbulent draft off Route 4 and Route 17 and the flat Hackensack valley, so exhaust from one appliance gets pulled into the neighboring flue. This is worse on north-south streets with no tree cover. We spec taller center stacks and wider overhangs on multi-flue caps for these exposures, and we document the draft improvement with smoke testing.
