A Level company - serving Newark, NJ

Gelco Chimney Cleaning Service Nationwide

Every visit starts with

Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed

Worth knowing

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 Newark Homeowners Choose Gelco Chimney Cleaning

Level Two Chimney Newark provides independent Gelco service in Newark, including chimney cleaning, inspection, and repair across Newark, NJ, with a documented camera record on every visit. We service Gelco 5″, 6″, 7″, and 8″ flexible aluminum liners in the exact housing stock where they’re most common: pre-1940 rowhouses and multi-family flats whose chimneys were built for coal, converted for oil, then converted again for gas, often without relining the oversized flue. We’re not affiliated with or authorized by Gelco, and we say that plainly. What we are is the crew that’s pulled enough corroded, kinked, and soot-packed Gelco liners out of Newark chimneys to know precisely how they fail, what’s repairable, and what belongs in the scrap pile. Call (862) 245-4309 for a written price before any work starts.

Why Trust Level Two Chimney Newark for Your Gelco Chimney Cleaning?

Gelco’s flexible aluminum liners are thin by design. They’re economical, easy to pull through an offset flue, and in the right application they vent a gas appliance fine. The catch is that “right application” is specific, and Newark’s housing stock rarely matches it. Corrine Halstead, who runs our Newark operation, learned masonry and ventilation at New York City College of Technology in Brooklyn before spending years pulling liners from Essex County chimneys. She’ll tell you the same thing she writes on every inspection sheet: a Gelco liner in a Newark rowhouse needs the crown, the mortar joints, and the termination checked every time, because any water that gets past the crown ends up sitting against aluminum. We photograph everything. Clause 4 of the Haven Standard requires a documented photo record on every job, and we’ve run that way since 2009. You’ll see the liner condition, the crown, and the flue opening before anyone asks you to sign anything.

Common Gelco Chimney Cleaning Problems We Fix in Newark

Common Gelco Chimney Cleaning Problems We Fix in Newark

These are the issues we see repeatedly in Gelco installations across Newark, from the Ironbound to the North Ward and up through Branch Brook Park’s rowhouse blocks:

  • Corrosion and pinholing from acidic condensate. Gas appliances produce moisture that carries mild acids. Aluminum liners, especially older Gelco runs, develop pinholes where that condensate pools at the base or along horizontal offsets. Once pinholes start, exhaust leaks into the masonry cavity. We identify this on camera, not by guess.
  • Mid-span kinks from unsecured brackets. Gelco liners are flexible, and in tall Newark chimneys it’s common to see a run that was never secured at the proper intervals. The liner sags, kinks, and restricts exhaust. We pulled a 6-inch Gelco liner from a 1950s Newark rowhouse where a collapsed mid-span kink from an old unsecured bracket was spilling water heater exhaust. Replaced the run and repointed the crown the same day.
  • Water infiltration around the Gelco termination. The aluminum top plate and rain cap on Gelco termination kits rust and warp over time, especially near Newark Bay and the Passaic River where ambient moisture runs high. Once the top plate warps, water follows the liner down and soaks into the flue. The crown above it is usually the real problem.
  • Soot packing against corrugated walls. Gelco’s corrugated aluminum profile creates ridges. When a gas appliance is slightly over-fired or the liner diameter doesn’t match the appliance’s BTU output, soot builds against those ridges fast. A standard brushing sometimes isn’t enough; the liner has to be inspected for buildup that’s hardened.
  • Deteriorated mortar joints above the liner. Newark’s freeze-thaw cycle works on brick relentlessly. A Gelco liner can be perfectly intact while the masonry stack above it crumbles. Missing mortar joints let water into the flue, which runs down and attacks the aluminum. We repoint and rebuild crowns as a standard part of Gelco service here.

Gelco Parts & Our Repair-vs-Replace Approach

We use genuine Gelco termination components when they’re available and still solid: top plates, rain caps, and connector pieces. For liner replacement, though, we’re honest about the math. Aluminum is cheaper up front. In a Newark chimney that’s oversized, unlined masonry, or exposed to repeated freeze-thaw water intrusion, a quality 316L stainless steel liner from DuraFlex or HeatShield often makes more sense over ten years. We’ll show you the camera footage and let you decide. If the Gelco liner is intact and merely clogged, our Chimney Cleaning & Sweep services restore function for a fraction of replacement cost. We don’t sell liners that aren’t needed. The camera doesn’t negotiate, it just shows what’s there. Call (862) 245-4309 and we’ll put the evidence in writing before any work begins.

Our Gelco Service Process - Step by Step

Our Gelco Service Process - Step by Step
  1. 1
    Diagnosis. A named technician arrives. We run NFPA 211 Level 2 camera inspection down the Gelco liner, noting diameter, corrugation condition, kinks, pinholes, and creosote class. We photograph the crown, termination, and flue opening.
  2. 2
    Written scope. Before any work starts, you get a written price, written scope, and written warranty under Haven Standard Clause 1. H.A.V.E.N. is how we remember it: Have it in writing. No verbal-only pricing, ever.
  3. 3
    Repair or replacement. If the Gelco liner is sound, we sweep it with brushes matched to the corrugated aluminum profile. If it’s failed, we pull it and install a Gelco-compatible liner or a 316L upgrade, securing it at the proper intervals this time.
  4. 4
    Documentation. Clause 4 of the Haven Standard means a photo record on every job. You get before-and-after images, the written warranty, and the inspection findings on paper. Nothing verbal-only.

Gelco Products We Service & Install in Newark

We service the full Gelco flexible aluminum liner range: 5″, 6″, 7″, and 8″ diameters, including termination kits and connector components. Most of what we see in Newark are 6″ and 7″ runs on gas water heaters and boilers, and 5″ liners on smaller gas logs. We stock common termination components locally for faster turnaround, and we source materials through Haven’s buying network, which includes Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield. That network exists to keep prices honest, not to lock you into one manufacturer.

Level Two Chimney Newark isn’t tied to any single manufacturer. Alongside Gelco, we service liners and venting from DuraFlex and HeatShield regularly, and we install from both when a 316L stainless upgrade is the better call. The liner brand matters less than the condition of the masonry around it, and we’ll tell you that on the first visit.
