A Hearthstone company - serving Staten Island, NY

Gelco Chimney Cleaning & Sweep 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.

Gelco Chimney Cleaning & Sweep in Staten Island: What to Know First

We provide independent Gelco chimney cleaning and sweep services across Staten Island, from annual maintenance to Level-2 camera inspections that document what we find. Most Gelco cleanings and inspections are completed in a single visit, with upfront pricing agreed before we start. We’re not here to sell you a liner you don’t need; if the chimney’s sound, we’ll say so. If it isn’t, you’ll hear that too.

Call (516) 613-3035

This page is for Staten Island homeowners who own a Gelco chimney cap, Gelco top-sealing damper, or Gelco liner system and want it serviced by technicians who know the brand’s quirks rather than learning on your job. Call (516) 613-3035 to speak with a live person, any hour, any day.

How Gelco Products Fail - and How We Fix Them

  • Gelco chimney caps in the Multi-Flue series trap moisture against the flue wall when the mesh screen clogs with Staten Island’s heavy oak and maple leaf fall, especially in neighborhoods like Great Kills and Annadale where mature canopy cover is dense. We remove the cap, clean the screen with a wire brush and compressed air, and reseat it with fresh sealant rather than forcing a replacement.
  • Gelco Lyemance and Lock-Top top-sealing dampers develop creosote buildup on the silicone rubber gasket that prevents full closure. The damper then leaks conditioned air and admits downdrafts. We clean the gasket surface with a solvent-safe for silicone, check for cracking, and replace only the gasket if the cast-aluminum frame is sound. Most chain operators sell the whole damper assembly.
  • Gelco stainless steel flexible liners in the 316Ti series accumulate glazed creosote near the top third of the flue where Staten Island’s prevailing southwest winds create temperature inversions. Standard brushing won’t touch it. We apply a creosote modifier, let it dwell, then run a rotary poly brush at controlled RPM to avoid scoring the titanium-stabilized alloy.
  • Gelco pre-fabricated chimney chase covers on manufactured homes in Staten Island’s South Shore develop salt corrosion at the drip edge from winter road-salt aerosol carried on nor’easter winds. During sweep and inspection, we document the corrosion stage with photos. Early-stage pitting gets treated and painted; we only recommend replacement when the steel substrate is compromised.
  • Gelco fireplace doors and enclosures lose their tempered glass seal after decades of thermal cycling, but the cast iron frame often outlasts two or three glass sets. We clean the frame channels, check for warping, and source replacement glass to the original Gelco temper specification rather than substituting standard window glass that will shatter on the first overfire.

Our Gelco Chimney Cleaning & Sweep Process

  1. 1
    Call intake. A live person answers, notes your Gelco model if you know it, and schedules. We bring common Gelco gaskets and hardware to the first visit.
  2. 2
    Level-1 or Level-2 inspection. We determine which level applies based on NFPA 211 standards and your last inspection date. Level-2 includes interior camera documentation.
  3. 3
    Diagnosis with photos. You see what we see. We explain whether the issue is cleaning-only, a wear part, or structural. No recommendations without evidence.
  4. 4
    Parts decision. We stock quality aftermarket equivalents where they meet or exceed Gelco spec, and source OEM when the application demands it. You choose; we document.
  5. 5
    Cleaning and repair. Rotary or hand brushing as the flue condition requires. Damper service, cap resealing, or gasket replacement done on site.
  6. 6
    Combustion test and documentation. We verify draft and spillage, then leave you with a written report, photos, and the 90-Day Done Right Promise.
