Why Passaic Residents Choose Us for Gelco Service
Passaic’s housing market doesn’t reward guesswork. When you’re dealing with a 1920s three-unit brick row house on Passaic Street and the chimney serves a gas boiler that replaced oil twenty years ago, you need someone who’s seen that exact setup before. Gary Murphy leads every job himself—he’s the one on the roof, the one running the camera, the one explaining what the flue actually looks like.
We’ve worked with Gelco stainless steel liners and multi-flue caps for over a decade. We know the difference between a Gelco Ultra-Flex 316Ti and a Pro-Flex 304, and we know which one holds up when Passaic’s river-valley humidity starts working on the mortar joints. Our parts stock includes genuine Gelco OEM liners for replacements where UL listing matters, plus quality aftermarket caps and dampers for repairs where they don’t. Over 1,100 homeowners have trusted us with their chimneys, and we’ve maintained a 4.7-star average across 1,142 verified reviews—one of the deepest proof records in this trade.
Gary grew up in Yonkers’ Nodine Hill neighborhood, trained through Westchester Community College’s Building Trades program, and spent years working real jobs across the Hudson Valley before running Sterling himself. His father was a finish carpenter. The lesson stuck: look the homeowner in the eye and explain exactly what you found. No upselling, no padding. As we sometimes say on jobs: “I’ll tell you what I see, not what sells.”
Common Gelco Chimney Cleaning Problems We Solve in Passaic
- Condensate corrosion at liner base in oversized coal-era flues. Passaic’s row houses commonly have 8×12 or larger clay flues built for coal heat. When a Gelco Ultra-Flex 316Ti gets installed during oil-to-gas conversion without resizing, the wide, cold flue causes gas exhaust to condense. The result: acidic, rust-colored deposits that eat the bottom 18 inches of stainless steel. We catch this with Level 2 camera inspection and typically repair by shortening the liner and adding a condensate drain fitting.
- Bird screen clogging from Passaic’s dense street-tree canopy. Gelco Multi-Flue Caps with factory bird screens work well until October leaf drop hits. On streets like Passaic Street near Van Houten Avenue, we’ve pulled caps packed solid with maple and oak debris. The blockage creates downdraft pressure that can cause gas appliances to overgas—carbon monoxide risk, not just poor draft. We clean the screen, check draft pressure with a manometer, and recommend elevated-cap or external-screen alternatives where trees overhang.
- Cleanout tee separation from building settling. Passaic sits on Passaic River floodplain soils that shift with seasonal moisture changes. We’ve found Gelco liner cleanout tees pulling apart at the joint, invisible from below without a camera. The gap leaks condensate into the chimney base, accelerating brick spalling. Resealing with high-temp silicone pack buys 5+ years if the liner body is sound.
- Premature crown coating failure on south-facing exposures. Hudson River valley wind drives rain against Passaic’s chimney crowns with unusual persistence. Gelco crown coatings we apply after cleaning typically last 8-10 years in sheltered conditions; on south-facing stacks above the third floor, we’ve seen failure in 4-5 years. We note exposure during inspection and use heavier-build elastomeric on vulnerable crowns.
- Cross-flue contamination in gang-flued multi-unit stacks. Passaic’s 2-4 unit buildings often have original flue systems where partitions have shifted or eroded. A Gelco liner in one flue can leak exhaust into an adjacent unit if the clay divider is compromised. Our camera inspection maps the full flue geometry—we’ve found three “separate” flues actually connected above the roofline in a single Passaic tenement.
Gelco Service in Passaic: What Local Conditions Mean for Your Equipment
Passaic’s location in the Passaic River valley creates locally elevated humidity and periodic flooding conditions that accelerate mortar joint deterioration and spalling on older brick chimneys—meaning chimney sweeps here frequently encounter crumbling crowns and water-damaged flue liners that go hand-in-hand with cleaning appointments. This isn’t abstract: on a row house on Passaic Street near Van Houten Avenue, our sweep found a Gelco Ultra-Flex 316Ti liner installed 8 years ago during an oil-to-gas conversion. The oversized 8×12 clay flue—originally for coal—had produced acidic condensate that corroded the bottom 18 inches of the liner, leaving a pool of rust-colored soot in the cleanout tee. We removed the damaged section, installed a shorter replacement liner with a condensate drain fitting, and sealed the tee with a high-temperature silicone pack. The owner, a landlord, now schedules annual Level 2 camera inspections to catch base corrosion early.
The lesson for Passaic: cleaning appointments here routinely turn into repair discoveries. We build that into our scheduling and our estimates. A “routine sweep” in a 2005 suburban colonial is a different animal than a “routine sweep” in a 1925 Passaic three-unit where nobody’s been on the roof since the first Bush administration.
Gelco Models & Products We Service in Passaic
We handle the full Gelco residential line, with same-day parts availability for most Passaic repairs:
- Gelco Ultra-Flex 316Ti liner: Our go-to for Passaic’s harsh condensate environments. The titanium-stabilized alloy resists the acidic moisture we find in oversized flues. We stock replacement sections and bottom termination fittings for same-day repair when corrosion is localized.
- Gelco Pro-Flex 304 liner: Suitable for properly-sized flues with good draft. We see fewer of these in Passaic’s older housing stock, but install them where the original flue dimensions match modern gas appliance output.
- Gelco Multi-Flue Cap with bird screen: The standard cap for multi-unit Passaic buildings. We stock OEM and quality aftermarket versions; the aftermarket units often use heavier-gauge mesh that resists leaf clogging better than factory spec.
We use genuine Gelco OEM liners for replacements to maintain UL listing integrity. For non-structural parts—caps, crowns, dampers—we stock quality aftermarket equivalents that meet or exceed Gelco specs. We recommend repair over replacement when the liner body is sound. Most Passaic appointments carry common fittings; specialized orders run 2-3 business days.

FAQs — Gelco Chimney Cleaning in Passaic
Yes. Any Gelco liner over 20 years old in Passaic’s pre-war housing should get a video scan before sweeping. We’ve found bottom-termination corrosion and tee separations in 1990s-era liners that look fine from the fireplace opening. The inspection adds about 45 minutes but prevents pushing a brush through a compromised flue. Call (844) 660-6590 to book—estimates are free.
Passaic’s mature street-tree canopy drops heavy debris October through November, and Gelco’s factory bird-screen mesh is fine enough to trap it. The cap chokes, draft reverses, and your gas appliance can overgas. We clean the screen and check draft pressure; if it happens yearly, we install an elevated cap or external screen that sheds leaves before they pack. Same-day service available—call (844) 660-6590.
Yes, if each flue is structurally separate. We camera-map the full stack first—Passaic’s gang-flued buildings often have eroded clay partitions that create cross-contamination. If dividers are intact, we install individual Gelco liners sized to each appliance. If they’re compromised, we recommend rebuilding the flue separation or converting to a single approved venting system. Every multi-flue Passaic job starts with Level 2 inspection.
A properly sized Gelco liner fixes it, but sizing matters. The original oversized flue—maybe 8×12 for coal or oil—needs a liner diameter matched to your gas appliance’s BTU output and venting category. Too wide, and you get the same condensate corrosion we found on Passaic Street. We calculate exact sizing from manufacturer specs, then install with condensate drain where needed. Call (844) 660-6590 for a free assessment of your flue dimensions.
Cap replacement alone typically doesn’t require permit in Passaic, but liner work or crown rebuilds may. Multi-unit buildings add complexity—some landlords handle permits centrally, others expect the contractor to pull them. We clarify this during our free estimate and can manage permitting where needed. For your specific building, call (844) 660-6590 and we’ll check what’s required.
