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 & Sweep in Plainview: What to Know First
We provide independent Gelco chimney cleaning and sweep services in Plainview, with most appointments booked within a week during the off-season and two to three weeks once October arrives. A standard Gelco sweep and Level 1 inspection runs $199-$289; if your Gelco system needs a Level 2 camera inspection for creosote evaluation or flue-tile assessment, expect $289-$425. We do not quote over the phone for work we have not seen - the estimate you get is the invoice you pay, and we photograph everything.
This page is for Plainview homeowners who installed a Gelco chimney cap, Gelco top-sealing damper, or Gelco chimney liner in the last ten to twenty years and need it cleaned, inspected, or cleared of creosote buildup before burning season. We are not affiliated with or authorized by Gelco. We are an independent Gelco service provider with no ties to the manufacturer, which means we use the parts that actually solve the problem, not just the parts in their catalog.

How Gelco Products Fail - and How We Fix Them
- Gelco Model C chimney caps clog with creosote at the mesh corners. The C-series uses a 5/8-inch mesh that catches more spark than competing 3/4-inch designs, but in Plainview’s damp Long Island winters, that tighter weave traps sticky second-stage creosote. We remove the cap, ultrasonic-clean the mesh in our shop, and reseat it with fresh stainless hardware. If the mesh is corroded through, we source direct-fit replacement caps from Gelco or match the spec with a Copperfield equivalent.
- Gelco top-sealing dampers lose their seal after seven to ten years of heat cycling. The cast-aluminum frame warps slightly, and the silicone gasket compresses permanently. Homeowners notice a cold downdraft or smell fireplace odor in summer. We camera-inspect the frame for cracks, replace the gasket with OEM Gelco kit GTD-2000 or upgrade to a HeatShield refractory seal if the frame itself has shifted. The fix takes one visit.
- Gelco Pre-Fab chimney liners sag at the collar joint in oil-to-gas conversions. Plainview’s older split-levels near Manetto Hill Road often had oil heat converted in the 1990s, and the Gelco aluminum liner rated for oil soot was never swapped for stainless. We pull a camera to check for condensation corrosion at the lower joint. If the liner is intact, we sweep and treat with ACS anti-creosote. If perforated, we replace with DuraFlex 316Ti stainless, which handles gas condensate.
- Gelco wind-directional caps seize in the “closed” position after coastal storms. The baffle hinge on Gelco WD-series caps collects salt and grit from Long Island Sound air. We disassemble the baffle, polish the pivot pin, and apply a high-temp dry lubricant that won’t attract fresh grit. We see this most in Plainview homes within two miles of the water, especially after nor’easters.
- Gelco chase covers pool water at the corners where the drip edge meets the brick. The factory caulk bead shrinks after five freeze-thaw cycles. Water wicks into the chase, saturating the flue and accelerating creosote absorption into the masonry. We remove the cover, reflash with Copperfield counter-flashing, and reseal with a flexible refractory caulk that moves with the temperature swing.
Our Gelco Chimney Cleaning & Sweep Process
- 1
Call and schedule. A live person answers (934) 348-4832, 24 hours a day. We ask the Gelco product name or series if you know it, the fuel type, and the last sweep date.
- 2
Arrival and protection. Our technician arrives in a marked truck, uniformed, with boot covers and drop cloths. We inspect the Gelco cap or damper for visible damage before touching a tool.
- 3
Camera inspection and documentation. We run a Level 1 or Level 2 camera inspection depending on age and condition. You see the photos on the spot. We explain what we found in plain English - no jargon, no upsell.
- 4
Sweep and service. We rotary-sweep the flue, clean the smoke chamber, and service the Gelco component - cap, damper, or liner collar - using OEM Gelco parts or professional-grade equivalents from DuraFlex or HeatShield when they outperform the original.
- 5
Combustion test and final documentation. We burn a small test fire or run the appliance and check draft pressure. You receive a written report with photos, the 90-Day Done Right Promise, and a plain-English verdict on what needs attention now versus what can wait.
- 6
Cleanup and departure. We vacuum every surface we touched. Most Gelco jobs in Plainview finish in two to three hours.

Why Plainview Homeowners Call Hearthstone Chimney Co. for Gelco Work
Plainview homeowners have called us for over 42 years because we document what we find and stand behind what we do. The 90-Day Done Right Promise is in writing, no arguing - if it’s not right, we come back. Our technicians are background-checked, uniformed, and trained on Gelco’s specific failure patterns, not just generic chimney anatomy. When a Gelco part is back-ordered or superseded, we have working relationships with DuraFlex, HeatShield, and Copperfield to keep the job moving in one visit. We are not the cheapest outfit on Long Island. We are the one that plans to be here in thirty years to answer the phone if something goes wrong.
Russell Haines, our owner, learned the trade at Los Angeles Trade-Technical College before spending the better part of two decades running a brush down chimneys across Long Island, including plenty of homes near the Old Country Road corridor in Plainview. He has a reputation for finding the thing the last guy missed.
FAQs
No - professional cleaning by an independent service provider does not void Gelco’s product warranty, provided no modifications are made to the original design. We document our work with photos to protect your warranty status if a claim ever arises. Call (934) 348-4832 if you need documentation for your records.
We stock common Gelco gaskets, mesh panels, and damper hardware, and we order direct from Gelco distributors when the OEM part is the right solution. When a professional-grade aftermarket part from DuraFlex or HeatShield outperforms the original - a 316Ti liner replacing aluminum, for instance - we explain the trade-off and let you decide. No surprises on the bill.
The camera tells the story. If the flue tiles are intact, the damper seals, and the liner shows no perforation, a sweep is all you need. If we find cracked tile, a warped damper frame, or liner corrosion, we show you the photo and explain whether the repair is urgent or can wait until next season. Nothing is recommended without evidence you can see.
Once per year for wood-burning systems, per NFPA 211. Oil and gas Gelco systems in Plainview often go two years between sweeps, but we still recommend annual inspection - Long Island’s freeze-thaw cycles and coastal humidity accelerate deterioration you cannot see from the firebox. Call (934) 348-4832 to book before burning season fills our schedule.
Stage 3 glazed creosote builds up, which cannot be removed with a standard brush and requires chemical treatment or replacement of the liner. More critically, creosote ignites at 451 degrees, and a chimney fire can crack flue tiles or warp the Gelco cap, turning a $250 sweep into a $2,000 rebuild. If the chimney is doing its job, you won’t think about it once all winter - that’s exactly the point. Call (934) 348-4832 and we’ll keep it that way.
