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 Chimney Cleaning in Passaic, NJ | Level Two Chimney Clifton
We provide independent Passaic Chimney Cleaning & Sweep and cap service across Passaic, and the work here is different from what you’d find in a neighboring suburb. Passaic’s pre-war brick rowhouses and multi-family buildings were built for coal, not gas or wood, and that legacy shapes every Gelco cap and crown we service. Acidic coal tar residue from converted flues corrodes galvanized cap bases faster than standard wood creosote ever could. If you have a Gelco cap on a Passaic chimney, call (551) 282-9640 and we’ll put a camera down the flue and show you exactly what’s happening.
Why Passaic Residents Choose Us for Gelco Service
Our crew has worked on Gelco chimney systems throughout Passaic’s housing stock for years. We know how a Gelco Standard Multi-Flue Cap behaves on a shared three-unit stack on Gregory Avenue versus a Hi-Wind Cap on a detached corner lot. We’re not manufacturer-authorized, and we’re upfront about that. We’re an independent Gelco sales & service provider, which means we can tell you plainly when a patch makes sense and when a cap needs to come off entirely. Corrine Halstead, our owner, learned the trade through the building trades program at CUNY Kingsborough Community College and has spent years running cameras through Passaic’s converted coal flues. She sets the standard: written price before work starts, photo record when it’s done. The camera doesn’t guess. Neither do we.
Common Gelco Chimney Cleaning Problems We Solve in Passaic
- Corroded cap bases from flood-driven moisture. Passaic sits directly on the Passaic River, and many blocks flood repeatedly. Water wicks into chimney bases, Gelco galvanized steel bases corrode at the mortar line, and the cap loosens. We see this constantly near the river. The upper cap looks fine; the base is rusted through.
- Mortar joint cracks on multi-flue caps. Shared chimney stacks serving two, three, or four units put stress on Gelco multi-flue caps. Thermal cycling between hot flue gases and Passaic’s damp winters opens hairline cracks at the base joints. Those cracks let water in, and freeze-thaw does the rest.
- Premature corrosion from coal tar residue. Passaic’s converted coal flues leave behind acidic residue that behaves nothing like wood creosote. It eats at galvanized steel Gelco cap bases from the inside out. A cap that should last 15 years fails in six or seven. We can show you the pitting on camera.
- Draft restriction on coal-converted flues. A Gelco cap sized for a modern gas flue doesn’t always play well with an old coal boiler flue. If the cap is undersized, draft suffers and backdrafting into adjacent tenant units becomes a real risk. We verify draft on every connected unit before we finish.
- Hairline fractures in Gelco crown coatings. On multi-family Passaic chimneys, the crown coating takes abuse from wet winters and hot flue gases in the same day. Hairline fractures spread. Water gets into the mortar bed, spalling starts, and the crown needs repointing before a new cap even makes sense.
BeforeAfterGelco Service in Passaic: What Local Conditions Mean for Your Equipment
Here’s what makes Gelco work in Passaic genuinely different from the same service in Clifton or Garfield. Passaic’s chronically flood-prone blocks near the Passaic River leave Gelco caps with a split condition: the base is corroded and crumbling from decades of water wicking up through the brick, while the crown and upper stack look perfectly serviceable from the roofline. A standard sweep who only checks from above will miss it. We don’t quote any cleaning or Chimney Repair in Passaic until we’ve done a ground-level masonry inspection. On one row house on Gregory Avenue, our tech found a Gelco Draft King cap with a rusted base and an intact crown. We removed the old cap, repointed the top course of brick where water had seeped in, and installed a new Gelco multi-flue cap sized for the original coal boiler flue, then verified draft on all three connected units. That’s the Passaic pattern: the base fails first, and if you only look from the roof, you’ll quote a cleaning when the real problem is still rusting at the bottom.
Gelco Models & Products We Service in Passaic
We work on the full Gelco chimney product line in Passaic: the Gelco Standard Multi-Flue Chimney Cap, the Gelco Hi-Wind Cap, the Gelco Draft King Cap, and the Gelco Custom Cap. For cap replacement, we use genuine Gelco components when they’re available and appropriate for the installation. When a coal-converted flue or a high-moisture river-adjacent location calls for it, we source quality aftermarket equivalents that hold up better in Passaic’s specific conditions. We stock common multi-flue and Draft King replacement parts locally, which means we’re not waiting on a distributor to get your cap swapped. Corrosion or flood damage that has compromised a cap’s structural integrity gets a replacement, not a patch. We’ll show you the camera footage before we make the call.
Gelco Service Pricing in Passaic
A Gelco cap replacement in Passaic typically runs $350 to $700 depending on cap size, flue count, and whether the base requires repointing. Mortar repointing on a multi-flue chimney base adds $150 to $450. A standard chimney cleaning and camera inspection runs $189 to $329 for a single flue, with multi-flue buildings priced by flue count. What drives cost here: Passaic’s coal-era flues often need a cap sized differently from the original, and flood-damaged bases regularly need masonry work before the new cap goes on. Every quote is written before work starts, and every visit includes a documented photo record under Clause 4 of the Haven Standard. Call (551) 282-9640 for an exact written estimate. The estimate is free.

FAQs - Gelco Chimney Cleaning in Passaic
Because Passaic floods, and floodwater wicks up through the brick at the chimney base for decades. The galvanized steel base of your Gelco cap sits in that damp zone and corrodes from the mortar line upward while the crown above stays dry and intact. This split condition is exactly why we inspect from ground level before touching the cap. Call (551) 282-9640 and we’ll show you the corrosion on camera.
Yes, when it’s sized correctly. Gelco multi-flue caps are built for that configuration, but on a Passaic rowhouse originally built for coal, the flue dimensions often differ from what a standard sizing chart assumes. We measure each flue, check the coal-era dimensions, and verify draft on every connected unit after installation. That last step matters. A backdraft into an adjacent tenant’s unit is not a small problem.
We can’t speak for Gelco’s warranty terms, but in our experience, flood-related corrosion at the base is nearly always classified as environmental damage rather than a manufacturing defect. What we can do is document exactly what happened with photos and a written report, which is what you’ll need if you pursue a claim. We’ll also recommend a cap base or installation method that holds up better against Passaic’s river moisture.
If the cap is loose, cleaning should wait. A loose cap means the base anchor or mortar bed has already failed, and running a brush through the flue can dislodge it further, dropping metal into the chimney or off the roof. We’ll come out, assess the base, and tell you plainly whether it needs reseating or full replacement. Call (551) 282-9640 and we’ll get to it before the next storm.
They protect the flue opening from rain and animal entry, but no cap removes coal tar residue that’s already inside the flue. That residue needs to be brushed out, and in some Passaic chimneys it has already eaten into the clay tile liner. A camera scan will show us what you’re working with. We’ll write up exactly what we find and what it costs to fix before we do anything else.
