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.
Why Clifton Homeowners Choose Gelco Chimney Cleaning
We provide Clifton Gelco service across Clifton, NJ, and we see Gelco liners, caps, and top-mount dampers on Clifton chimneys every week. What sets our Gelco work apart is simple: our techs keep a library of Gelco installation manuals and failure histories, so when a creosote problem or a sticking damper shows up on a Gelco system, we already know the likely cause before the camera goes down. We’re not affiliated with or authorized by Gelco, and we don’t pretend to be. We’re an independent local service provider that knows these products well enough to fix them right the first time. Call (551) 282-9640 to book a Gelco inspection or cleaning, and you’ll get a written price before any work starts.
Why Trust Level Two Chimney Clifton for Your Gelco Chimney Cleaning?
Gelco chimney systems show up on a lot of Clifton’s older colonials and two-families, and our technicians work on them weekly. That repetition matters. A tech who sees one Gelco liner a month is guessing. A tech who sees three a week knows that a Gelco 6-inch rigid liner in a 1940s Botany Village home is going to behave differently than the same liner in a 1960s ranch near Van Houten Avenue, because the flue path, offset geometry, and fuel history are different. Corrine Halstead, our owner, runs the same discipline on every Gelco job: camera first, written findings second, written price third. She grew up in Queens, came up through the building trades program at CUNY Kingsborough, and has been working Clifton chimneys long enough to know that a Gelco top-mount damper on a two-flue stack in Athenia has a different failure pattern than one on a single-flue Cape Cod. We don’t guess at Gelco problems. We document them, name them, and price the fix before a brush touches the flue.
Every Gelco service call includes our Chimney Cleaning & Sweep services with a Level 2 camera-scan inspection and documented photo record, under Clause 4 of the Haven Standard. That means you walk away with photos of what we found, not just a verbal summary. We also deliver a written scope and written warranty before any work begins, because a verbal estimate that shifts by invoice time is not an estimate at all.
Common Gelco Chimney Cleaning Problems We Fix in Clifton

- Glazed creosote on Gelco 6-inch rigid liners. Clifton homeowners burning unseasoned wood with the damper half-closed create exactly the conditions that turn creosote into a hard, tar-like glaze. On a smooth Gelco 6-inch rigid liner, that glaze bonds tight and mechanical scraping is the only honest removal method. We see it most on wood-burning inserts in 1920s-1940s colonials where the original coal chimney was never relined and the Gelco liner is doing all the containment work.
- Rust at the mesh-to-frame seam on Gelco multi-flue caps. Clifton winters mean road salt, rain, and freeze-thaw cycles. After three to five winters, Gelco multi-flue caps with 5/8-inch mesh regularly develop rust at the seam where the mesh meets the frame. Once that seam opens, embers can pass through. We wire-brush the mesh, reseal the frame, and reinstall when the cap is structurally sound, or quote a replacement when it isn’t.
- Gelco top-mount dampers seized shut from creosote gumming the pivot pin. This is one of the most common Gelco failures in Clifton, especially on wood-burning fireplaces that haven’t been swept in years. The pivot pin gums up, the damper won’t open, and the fireplace won’t draft at all. We free the pivot with a penetrating solvent rated for that hinge, then address the creosote load that caused it.
- Kinked Gelco oval flexible liners behind offsets in older Clifton chimneys. Many Clifton stacks from the 1920s-1950s have offset flue paths that were never designed for a smooth liner run. An 8-inch oval Gelco flex liner can kink behind those offsets, and the kink becomes a creosote trap that a standard Level 1 scan misses entirely. Our camera finds it. Then we tell you plainly whether the liner needs replacement or whether the offset can be corrected.
- Mixed-fuel condensation damage on Gelco liners in two-family homes. Clifton has an unusually high density of two-family homes, many with a single chimney stack serving two separate heating systems. When one flue runs a gas appliance and the other a wood-burning fireplace, the temperature differential creates acidic condensate that eats at Gelco liner seams over time. We schedule both units on the same appointment and carry enough liner material to address a full two-flue stack in one visit.

AfterGelco Parts & Our Repair-vs-Replace Approach
We prefer OEM Gelco caps, dampers, and liner components when they’re available, because the mesh gauge and pivot tolerances match the original install. A generic aftermarket cap with a thinner mesh will fail faster on a Clifton chimney exposed to road salt and wet winters. For repairs like crown coating or flashing, we use proven aftermarket materials that outlast the OEM sealant, because that’s simply the better product for that application. When a Gelco liner is kinked or corroded through, we say so plainly and quote a replacement rather than patching a firebox risk. We won’t sell you a liner you don’t need, and we won’t patch one that’s done. If you have a written estimate from another company, bring it in. We’ll give you a free second opinion, in writing, before you spend a dollar. Call (551) 282-9640 to schedule Gelco service in Garfield.
Our Gelco Service Process - Step by Step

- 1
Diagnosis. We run an NFPA 211 Level 2 camera scan down the Gelco liner or flue, documenting everything with photos. On a Gelco system, we’re specifically checking liner condition, cap mesh integrity, damper pivot operation, and creosote classification (Class I, II, or III). The camera doesn’t guess. Neither do we.
- 2
Written findings and written price. Before any brush or tool touches your chimney, you get a written scope and a written price. No verbal ranges, no “we’ll see what we find.” You know exactly what we’ll do and what it costs.
- 3
Repair or cleaning. For Gelco liners, we use mechanical scraping appropriate to the liner material, not aggressive rotary methods that can scar rigid stainless. For dampers, we free seized pivots with the correct solvent. For caps, we decide repair versus replace based on the mesh and frame condition we documented in step one.
- 4
Testing and verification. After the work, we run the camera again and take post-service photos so you can see the difference for yourself. Draft is verified, damper operation is confirmed, and every Gelco component is documented.
- 5
Warranty and record. You receive a written warranty and a documented photo record of the completed work, under Haven Standard Clause 4. If it’s not done right, we make it right under our 365-Day Done Right Promise.
Gelco Products We Service & Install in Clifton
Our crews service and install the Gelco product lines most common in Clifton: the 6-inch round rigid stainless steel chimney liner, the 8-inch oval flexible liner for offset flue paths, the multi-flue cap with 5/8-inch mesh, and the top-mount damper with stainless steel hood. We stock Gelco-compatible components locally for faster turnaround on caps and dampers, and we keep liner material on hand for same-week replacement jobs. If your Gelco product isn’t listed here, call us. We work on Gelco systems across the full residential range and we’ll tell you directly if we can service your exact model.
We Also Service These Brands

While we work on Gelco products regularly, we’re a multi-brand shop. We also service and install DuraFlex and HeatShield systems, and we stock materials from Olympia Chimney, Famco, and Copperfield. That matters because it means we recommend the right component for your chimney, not just the brand we happen to carry.
FAQs - Gelco Chimney Cleaning Service in Clifton
No. We are an independent service provider. We are not affiliated with or authorized by Gelco, and we say that plainly because you should know exactly who’s working on your chimney. What we bring is deep familiarity with Gelco products from years of hands-on service work across Clifton.
We prefer OEM Gelco caps, dampers, and liner components when they’re available, because the mesh gauge and pivot tolerances match the original installation. For repairs like crown coating or flashing, we use proven aftermarket materials that outperform the OEM sealant. We’ll tell you which is which, and why, before you pay for anything.
Most Gelco cleanings and inspections run two to three hours from setup to final photo documentation. Damper repairs and cap replacements add time depending on access and condition. We’ll give you a clear time window when you book, and a text when the named tech is on the way.
We service the Gelco 6-inch round rigid stainless liner, the 8-inch oval flexible liner, the multi-flue cap with 5/8-inch mesh, and the top-mount damper with stainless steel hood. If you have a different Gelco product, call us and we’ll tell you directly whether we can service it.
Independent service does not void a manufacturer’s warranty, and we document every step with camera photos and written records so you have evidence of proper care. If a warranty claim ever comes up, you’ll have the documentation to support it. That’s Clause 4 of the Haven Standard, and we’ve been doing it since 2009.
In Clifton, a Gelco chimney cleaning with a Level 2 camera inspection typically runs $180-$340 for the standard single-flue sweep, with damper repair or cap replacement quoted separately after we see the condition.
