Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Cap & Crown Across Passaic
Chimney cap and crown repair in Passaic typically runs $280-$780 depending on whether you need a cap reset, crown coating, or full rebuild, and most jobs are completed in a single visit. We dispatch crews to Passaic from our New York City office, so we’re familiar with the tight street parking and row-home roof access that comes with every job in this city. If you’re seeing ceiling stains after rain, or if your cap went missing in last week’s wind, call us at (973) 604-2986 - we’ll send a technician who knows Passaic’s brick rows and its flood-zone masonry problems.
Passaic’s housing stock is overwhelmingly dense, pre-WWII two- and three-family attached brick row homes where original coal-era flues were later converted to serve oil and gas boilers for multiple tenant units. That creates a city-wide pattern of shared, undersized, or unlined flues that require multi-unit coordination and inspection protocols not typical of single-family suburban chimney work. Our Chimney Cap & Crown team has worked these streets for decades. We know the difference between a simple cap swap on a single-flue ranch and the multi-flue cap installation a three-family stack off Passaic Street demands.
Why Hearthstone Chimney Co. Is Passaic’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 Passaic landlord calls at 10 p.m. because a tenant’s ceiling is dripping, someone picks up - not a voicemail, not a callback queue. Our technicians are background-checked, uniformed, and carry the professional-grade brands that fit Passaic’s older masonry: Gelco multi-flue caps, Olympia Chimney components, and Famco hardware sized for the non-standard flue spacing common in pre-war brick rows.
We document every inspection with photos and a plain-English verdict. You see what we see. No estimate for crown work or cap replacement moves forward without camera evidence you can review yourself. Our 90-Day Done Right Promise covers every job in writing - if it’s not right, we come back. No paperwork to dig up, no arguing. That’s the Keystone Standard, and it’s how we’ve operated since 1984.
Most jobs finish in one visit. We give you the full price before we start, and the number on the estimate is the number on the invoice. For Passaic’s older housing stock, that matters - landlords and long-term homeowners here have been burned by contractors who found “surprise” problems halfway through. We don’t work that way.
Our Chimney Cap & Crown Services in Passaic
Cap Installation
New cap installation in Passaic’s three-family rows often means fitting a multi-flue cap over two or three separate clay-tile flues in a single stack. Standard single-flue caps won’t cover the spacing, and a gap between caps invites water straight into the masonry. We measure on-site, fabricate or source the correct cap from Olympia Chimney or Famco, and secure it with proper storm straps. A typical multi-flue cap installation in Passaic runs $340-$620.

Cap Replacement
Storm-driven wind off the Passaic River shears off poorly secured caps or displaces them just enough to break the seal. We find caps dangling by one strap, or sitting in the gutter, or gone entirely. Replacement starts with inspecting the flue tops for damage from exposed weather, then fitting a cap that matches your flue count and spacing. Most cap replacements in Passaic are $180-$380 for single-flue, $320-$580 for multi-flue. We were called out to a three-family brick row off Passaic Street after heavy rain drove water down a stack serving three converted gas boilers, showing as a ceiling stain in the second-floor unit. Our tech found a cracked chimney crown and a displaced cap feeding a flashing failure at the roof line; we reset the multi-flue cap with Olympia Chimney components, coated and rebuilt the crown, and re-flashed the stack. During the Level 2 inspection we caught a cracked flue liner in the middle unit and flagged it to the landlord before first fire.

Crown Repair
The chimney crown is the concrete or mortar wash that seals the top of your masonry stack. In Passaic’s flood zone, moisture wicks up from the chimney base into lower masonry courses, then freezes and thaws through winter. That movement cracks the crown, opens mortar joints, and lets water penetrate the flue system. Crown repair means removing the deteriorated material, rebuilding with proper slope and overhang, and sealing with a waterproof crown coating. Full crown rebuilds in Passaic typically cost $480-$780; partial repairs and coating run $280-$460.

Crown Coating
For crowns with minor cracking but sound structure, we apply a flexible, waterproof crown coating that bridges hairline cracks and prevents new water intrusion. This is preventive maintenance that pays off in Passaic’s climate, where flood-zone moisture and freeze-thaw cycles destroy unprotected crowns in five to seven years. Crown coating is $280-$420 and extends the life of sound masonry significantly. We recommend it after any crown repair, and we use professional-grade materials from HeatShield and Copperfield formulated for northern New Jersey exposure.

Multi-Flue Cap
This is the cap Passaic’s three-family rows actually need. A single masonry stack carrying three separate flues cannot be properly protected by three individual caps - the gaps between them channel water onto the crown, and the mounting hardware conflicts. A custom-fabricated multi-flue cap covers all flues with a single hood, proper storm straps, and side screening that keeps animals out while allowing each flue to draft. We size and install multi-flue caps from Gelco and Olympia Chimney for the non-standard flue spacing common in Passaic’s 1890-1930 housing stock. Typical cost: $380-$680.

Custom Cap
Some Passaic stacks need more than catalog sizing. Oversized flues, unusual crown dimensions, or historic preservation requirements call for custom fabrication in copper, stainless steel, or galvanized steel. We measure, specify, and install custom caps with the same storm-rated hardware and screening as our standard line. Custom caps start around $520 and range to $940 depending on material and complexity.

Trusted Brands We Service in Passaic
We stock and install professional-grade chimney cap and crown materials from Gelco, Olympia Chimney, and Famco - brands built for the exposure and flue configurations common in Passaic’s older housing. Gelco’s multi-flue caps handle the non-standard spacing we find in three-family rows. Olympia Chimney’s storm straps and hardware withstand the wind shear off the river. Famco’s venting accessories fit the converted boiler flues that dominate this market. We don’t substitute builder-grade parts. The cap or crown we install is the same one we’d put on our own building.
Common Chimney Cap & Crown Problems We See in Passaic Homes
- Storm-driven wind and water shear off or displace the chimney cap on exposed river-facing brick stacks. Passaic’s position on the flood plain means no topographical shield from weather coming up the river valley. Caps that held for years in inland Clifton or Paterson fail here after a single severe storm. Once the cap is gone, rain pours straight into the flues and onto the smoke shelf.
- Cracked chimney crowns worsen faster here than in surrounding upland communities. Flood-zone moisture wicks into the chimney base and lower masonry courses, accelerating efflorescence, spalling, and mortar joint failure. The crown cracks, water penetrates, and the freeze-thaw cycle opens the damage wider each winter. We’ve rebuilt crowns in Passaic that were sound ten years ago and failed completely in three.
- Flashing failures at the roof line channel water into the chimney base. In Passaic’s dense rows, a flashing leak often shows as a ceiling stain in a tenant’s unit and gets mistaken for a plumbing leak. The landlord calls a plumber, the plumber finds dry pipes, and the real problem - wind-lifted flashing at the chimney-roof intersection - keeps dripping. Our Level 2 camera inspection finds the source before the wrong repair gets ordered.
- Missing or deteriorated caps in multi-flue stacks create shared carbon monoxide risks. In Passaic’s three-family rows, a single stack often carries three separate clay-tile flues - one per unit’s converted boiler - so a cap or crown problem here is a multi-tenant issue, not a single-home repair. Years of gas-appliance condensation silently crack tile sections and open joints. Without the cap to keep rain out and the crown to shed water, that deterioration accelerates. And because landlords and tenants often assume the chimney “belongs to someone else,” the hazard goes unreported until an inspection forces the conversation.

FAQs - Chimney Cap & Crown in Passaic
A single cap leaves gaps between flues that channel water onto the crown, and mounting three separate caps creates hardware conflicts on a narrow stack. A multi-flue cap covers all flues with one hood, proper storm straps, and side screening - the only configuration that protects a shared stack in Passaic’s row housing. We size and install multi-flue caps from Gelco and Olympia Chimney for the non-standard spacing common here. Call (973) 604-2986 for an exact quote - estimates are free.
It could be either, but in Passaic’s three-family rows with converted boiler flues, chimney flashing failure is the most common misdiagnosed source. Wind lifts the flashing at the chimney-roof intersection, water channels into the stack, and the stain shows two floors down where a tenant calls it a plumbing leak. Our Level 2 camera inspection finds the actual source with photos you can see. Don’t order the wrong repair. Call (973) 604-2986 and we’ll diagnose it properly - estimates are free.
Yes. Gas and oil appliances produce acidic condensation that deteriorates clay-tile flue liners, and in Passaic’s multi-flue stacks that deterioration affects all units sharing the stack. The National Fire Protection Association recommends annual Level 2 inspection for all chimneys serving any fuel-burning appliance. In Passaic’s flood zone, we also check for moisture damage to the crown and cap that gas-appliance condensation accelerates. Call (973) 604-2986 to schedule - estimates are free.
Chronic flooding and high water table drive persistent moisture into chimney bases and lower masonry courses. That moisture wicks upward, accelerates spalling and mortar joint failure, and undermines the crown from below while rain attacks from above. Caps in Passaic fail faster than in surrounding upland towns because the masonry they’re mounted to deteriorates faster. We address both problems: crown coating or rebuild to stop water penetration, and storm-rated cap installation to withstand wind shear off the river. Call (973) 604-2986 for an inspection - estimates are free.
The cap and crown protect the shared masonry stack, so yes - one properly installed multi-flue cap and one sound crown protect all flues in that stack. However, each unit’s flue liner must be inspected separately, and liner problems in one flue don’t get fixed by cap or crown work. We coordinate with landlords to inspect all units, document findings with photos, and prioritize repairs by safety risk. One call to (973) 604-2986 starts the process - estimates are free.
