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.

AfterGelco Chimchimney Cleaning in Passaic, NJ | Hearthstone Chimney Co.
We provide independent Gelco chimney service across Passaic‘s multi-family row homes, where a single shared stack often vents three separate boiler flues and factory caps fail faster than anywhere else in Passaic County. Our crew carries Gelco-compatible caps, dampers and liners on the truck, and most Passaic jobs finish in one visit. Call (973) 604-2986 for a free estimate - a live person answers, day or night.
Why Passaic Residents Choose Us for Gelco Service
Russell Haines learned this trade at Los Angeles Trade-Technical College before the soot became permanent, and he’s spent the better part of two decades working chimneys across Passaic County. His crew has cleaned and repaired stacks from Paterson’s Eastside to the blocks around Garrett Mountain, but Passaic itself - with its dense attached brick rows and river-bottom damp - keeps them busiest from September through March.
We are not a Gelco-authorized dealer. We are an independent service company that knows Gelco parts because we’ve installed, cleaned and replaced them in Passaic’s actual housing stock for years. That matters here. A technician who understands how Gelco multi-flue caps corrode on three-family shared stacks, or how Gelco dampers seize in damp unlined flues, brings something no factory certification can replace. We stock Gelco-compatible stainless caps and dampers for fast turnaround, document every inspection with photos you can see, and back every job with our 90-Day Done Right Promise - in writing, no arguing.
Our phone rings through to a live person 24 hours a day. Background-checked, uniformed technicians. Upfront pricing that matches the invoice. That’s the square deal.
Common Gelco Chimney Cleaning Problems We Solve in Passaic
- Gelco single-flue caps corrode and lift off. Passaic sits directly on the Passaic River in a chronic flood zone, and that river-driven moisture attacks stainless faster than upland communities. When a Gelco single-flue cap lifts, rain pours into clay tiles already weakened by years of gas-appliance condensation. We replace with Gelco-compatible stainless and reseal the flue.
- Gelco multi-flue caps rust at the seams over shared stacks. In Passaic’s three-family attached rows, one stack often serves three converted boiler flues. A single failed multi-flue cap jeopardizes every tenant unit beneath it, not just one. We coordinate with landlords and tenants, replace the cap, and inspect all three flues before we leave.
- Gelco top-mount dampers seize shut on damp, unlined flues. Passaic’s coal-era chimneys were retrofitted for oil and gas without proper lining, and that residual moisture causes Gelco dampers to freeze closed. No draft means combustion gases back up toward living spaces. We free or replace the damper and assess whether relining is the real fix.
- Gelco flexible liners pull loose at the top. When original clay tile behind a Gelco liner has cracked from flue-gas condensation in a retrofitted coal-era stack, the liner loses its anchor point. Our Level 2 camera inspection finds the separation, and we reline or reseal rather than push unnecessary rebuilds.
- Efflorescence and spalling accelerate mortar joint failure. Repeated Passaic River flooding drives persistent moisture into chimney bases. We clean the stack, assess structural integrity, and apply chimney waterproofing where the masonry can be saved - plain about when it cannot.
Gelco Service in Passaic: What Local Conditions Mean for Your Equipment
On Passaic’s attached three-family brick rows - the blocks off Passaic Street near the river, the streets running parallel to Broadway - a single masonry stack often carries three separate unlined boiler flues, one per unit. Landlords and tenants both tend to assume the chimney “belongs to someone else.” Nobody calls until a boiler backdrafts or a cap finally blows off.
Here’s what that means for Gelco owners specifically. A Gelco multi-flue cap failure on one of these shared stacks is a carbon monoxide risk for every tenant at once, not a single-address problem. Our crew has learned to knock on three doors, coordinate access, and run Level 2 camera scans through all three flues before we declare the job done. The moisture from Passaic’s flood-zone soil doesn’t just rust the cap - it keeps flue walls damp year-round, so condensation from modern gas appliances never fully dries, cracking clay tile and opening mortar joints where no one can see. Gelco equipment is built well, but no cap or liner was engineered for three-unit coordination in a river-bottom climate with 130-year-old masonry. That’s the Passaic reality we bring to every Gelco job.
Gelco Models & Products We Service in Passaic
We work on the full Gelco line: single-flue stainless chimney caps, multi-flue caps for shared masonry stacks, top-mount chimney dampers, and stainless flexible flue liners. Our trucks carry Gelco-compatible replacement caps and dampers in common Passaic sizes, so we’re not ordering parts while your chimney vents into the attic.
We fit OEM-grade Gelco-compatible stainless components and use quality aftermarket only when a factory part is discontinued. If your Gelco liner is intact, we reline and reseal. If the stack is beyond saving, we say so plainly. No surprises on the bill. Gelco sales & service details are available if you’re weighing new equipment against repair.
Gelco Service Pricing in Passaic
Gelco chimney cleaning and inspection in Passaic typically runs $189-$289 for a single-flue sweep with Level 2 camera inspection and photo report. Multi-flue cap replacement on a shared three-family stack generally falls between $340-$580 depending on cap size and access complexity. Gelco liner repair or partial relining starts around $890-$1,450 per flue when the existing clay tile can be salvaged as a host. Full liner replacement on deteriorated coal-era stacks requires a site visit for exact measurement.
Every estimate includes the camera inspection and photo documentation. Our $89 Seasonal Tune-Up applies to straightforward single-flue Gelco cleaning booked before peak season. Senior and veteran discounts run 5% on all services. The number on the estimate is the number on the invoice.

FAQs - Gelco Chimney Cleaning in Passaic
Yes, a Gelco multi-flue cap is designed for exactly this configuration, and it’s what we most often install on Passaic’s shared-stack row homes. The cap must be sized to the full footprint of the stack, not individual flue openings, and it needs proper clearance from all three flue terminals. We measure on site, coordinate access to all units for inspection, and install in one visit. Call (973) 604-2986 to schedule - we’ll check all three flues before we leave.
Passaic’s river-bottom location means persistent soil moisture and higher ambient humidity than surrounding upland towns. That moisture, combined with acidic condensation from modern gas appliances in unlined flues, attacks stainless seams from both sides. We specify heavier-gauge Gelco-compatible replacement caps and apply protective treatments where appropriate. The real fix often includes addressing flue lining so condensation stops. Call (973) 604-2986 for an inspection that finds the root cause.
Extremely common. Passaic’s coal-era chimneys were retrofitted for gas and oil without proper sizing or lining, and decades of cool, damp flue gases condense on clay tile, causing thermal cracking and joint failure. We verify with camera inspection before recommending any work - you’ll see the cracks yourself. If the Gelco liner is salvageable, we reseal rather than replace. Call (973) 604-2986 for a second opinion on any written estimate; ours is free.
For a proper Level 2 inspection and safe certification, yes. Each flue serves a separate appliance and must be inspected from both top and bottom. We’ve learned to coordinate with tenants and landlords efficiently - most Passaic three-families take 90 minutes start to finish once we’re inside. We document findings for each unit separately. Call (973) 604-2986 and we’ll walk you through the scheduling.
Sometimes, but often the damper is a symptom of a deeper problem. On damp, unlined flues common in Passaic, Gelco dampers seize because the flue never dries. Freeing or replacing the damper without addressing lining means you’ll be back in two seasons. We inspect first, show you the moisture source, and recommend the smallest effective fix - damper, liner, or both. Call (973) 604-2986 for an exact assessment and quote.
