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 Queens, NY | Hearthstone Chimney Co.
We provide independent Gelco chimney service across Queens, NY, with a focus on the oil-to-gas conversion relining and multi-flue cap work that dominates the borough’s 1920s-1950s brick housing stock. The one thing that makes our Gelco work here different is the shared-chase reality: most Queens chimneys carry three or four separate flue tiles in one stack, so we inspect every tile before we touch anything. If your Gelco liner, cap, or damper needs attention in Queens, call us at (516) 531-6315 for a free estimate with photos you can see and a plain-English verdict.
Why Queens Residents Choose Us for Gelco Service
We’ve been Chimney Cleaning & Sweep - Queens specialists for years, including a long stretch of older two-families and co-ops along the Woodhaven Boulevard corridor where the brick flues tell their own complicated history. Russell Haines, our owner, learned the trade at Los Angeles Trade-Technical College before spending the better part of two decades putting that education to work in the field. He and our crew know Gelco’s stainless-steel liner kits, multi-flue caps, and top-sealing dampers from installation through end-of-life, and we stock Gelco-compatible parts for fast turnaround.
We’re an independent shop - not authorized, sponsored, or warranty-endorsed by Gelco - but we’ve deliberately specialized in their products because so much of it is already in Queens chimneys. Our Gelco sales & service covers the full product line, and our Queens service area runs from Astoria down to the Rockaways. Every job comes with our 90-Day Done Right Promise in writing, no arguing. Calls are answered by a live person 24 hours a day, 7 days a week.
Common Gelco Chimney Cleaning Problems We Solve in Queens
- Undersized Gelco liners after oil-to-gas conversion. NYC’s accelerating oil-to-gas heating conversion mandates have created a borough-wide relining emergency. An oil-era clay-tile flue is dangerously oversized for a gas appliance, and Gelco flexible stainless liners installed during rushed conversions often end up undersized themselves. We measure the appliance output against the liner diameter and replace with a properly sized insulated Gelco stainless liner when the numbers don’t match.
- Multi-flue cap failure at the mounting flange. Gelco multi-flue caps on shared Queens stacks crack or lift after freeze-thaw cycles. Water gets down into the clay tile chase and loosens mortar joints already softened by decades of oil flue gas. We inspect the crown beneath the cap before recommending repair or replacement - sometimes the cap is fine and the crown needs repointing.
- Top-sealing damper gasket hardening. Gelco top-sealing damper gaskets harden and lose their seal on Queens chimney tops that bake in summer and freeze in winter. The damper sticks open, the boiler flue stops drafting properly, and carbon monoxide risk rises. We stock replacement damper assemblies and gaskets for same-visit fixes when possible.
- Coastal corrosion on spark-screen caps. Gelco spark-screen caps in the Rockaways and Howard Beach corrode and blow off in coastal wind events. Post-Sandy installations in this area weren’t always re-flashed correctly, so we find leak paths at the cap collar years later. Salt air off Jamaica Bay accelerates the damage.
- Crimp-seam separation at the liner termination. On a two-family attached brick house in Woodside we pulled the cap off a Gelco multi-flue installation and found the boiler-side stainless liner had separated at the crimp, dumping flue gas into the neighboring unit’s water-heater tile. We re-lined that side with an insulated Gelco stainless liner sized for the new gas boiler, repointed the softened mortar at the crown, and set a new Gelco multi-flue cap - which gave both families a sealed chase and a real draft again.
Gelco Service in Queens: What Local Conditions Mean for Your Equipment
In the attached brick rows of Woodside, Elmhurst, and Richmond Hill a single chase usually carries three or four separate clay flue tiles - boiler, water heater, and one or two sealed coal-era fireplace flues - so a homeowner calling us for a “fireplace cleaning” on a decorative firebox is almost always sitting next to an active, deteriorating oil-burner flue inside the same stack. That shared-chase reality means part of our job on every Gelco job here is figuring out which flue tile the customer actually needs serviced versus the one the gas conversion left properly sized. Queens’s vast stock of 1920s-1950s attached and semi-detached brick homes means chimneys here overwhelmingly serve oil-fired boilers rather than wood-burning fireplaces, and NYC’s accelerating oil-to-gas heating conversion mandates have created a borough-wide Queens Chimney Repair emergency. An oil-era clay-tile flue is dangerously oversized and improperly sized for a gas appliance. This conversion-driven chimney crisis is specific to the NYC boroughs and makes Queens work fundamentally different from the fireplace-focused cleaning market common in suburban or rural areas. If it’s wrong, we’ll say so. If we fix it, it stays fixed.
Gelco Models & Products We Service in Queens
We work on the full Gelco line: stainless-steel flexible chimney liner kits in single-wall and insulated configurations; multi-flue caps and custom stainless caps; top-sealing damper systems; and single-flue rain caps with spark screens. Our Level 2 camera inspections show you exactly which component has failed and why. We stock Gelco-compatible stainless liners, multi-flue caps, and top-sealing damper assemblies in OEM where they’re available and in quality aftermarket equivalents when Gelco has discontinued a size or fitting. For Queens customers, that means most jobs complete in a single visit. We’ll always be straight with you when the honest answer is that re-lining a 1920s Queens flue behind a new gas boiler is a better spend than repairing the old cap for the third time.

FAQs - Gelco Chimney Cleaning in Queens
Probably not safely. Oil-era clay flues are oversized for gas appliances, and many Gelco liners installed during rushed conversions are themselves undersized for the new boiler’s output. We measure the appliance BTU rating against the liner’s interior diameter. If the ratio is wrong, the flue gas cools too fast, condenses, and corrodes the liner from the inside out. Call (516) 531-6315 for a free inspection with photos.
We won’t know until we pull the cap and inspect the crown beneath it. Often the cap mounting flange has cracked from freeze-thaw, but the crown mortar is the real leak path. Sometimes repointing the crown and reseating the existing cap solves it. Other times the cap itself has corroded through at the salt-air line. Our camera inspection shows you both before you decide. Call (516) 531-6315 for an exact quote; estimates are free.
Because in Richmond Hill’s attached brick rows, your decorative fireplace almost certainly shares a chase with an active boiler flue that is the actual safety priority. The sealed coal-era fireplace flue isn’t venting anything, but the neighboring oil-burner tile may be cracked, unlined, or improperly sized for a recent gas conversion. We inspect every flue in the stack and report on each one. The fireplace cleaning you called about may be fine; the boiler flue next to it may not be.
The gasket hardening is accelerated here. Queens chimney tops experience wider temperature swings than inland areas - baking in summer sun, freezing in winter wind off the water. The silicone or rubber gasket on a Gelco top-sealing damper degrades faster under those conditions. We replace the gasket or the full damper assembly depending on corrosion at the frame. It’s a common call from Astoria to the Rockaways.
Check the flashing collar and the crown condition, but have a professional do it. Post-Sandy installations in Howard Beach and the Rockaways weren’t always re-flashed to current standards, and we’ve found leak paths at the cap collar that rotted the crown from underneath. Replacing the cap without fixing the collar just sets up the next blow-off. We inspect with a camera, show you the footage, and price both paths before you choose. Call (516) 531-6315 for a free inspection.
