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 Forest Hills, NY | Level Two Chimney Jamaica
A Chimney Cleaning & Sweep - Forest Hills service for Gelco systems costs between $189 and $329 for a standard sweep and Level 2 camera inspection, and most jobs are completed the same week you call. We service the original Gelco clay-tile flues that run through Forest Hills Gardens’ Tudor Revival homes, and the one thing that makes our work here different is simple: we expect these chimneys to be oversized, unlined, or structurally compromised, because most of them were built for coal in the 1910s and never properly converted. That changes how we clean, how we inspect, and what we recommend fixes for.
Level Two Chimney Jamaica is an independent Gelco service provider, not a manufacturer-authorized shop. We’re not pushing Gelco parts. We’re restoring what’s there and telling you plainly when it’s beyond saving. If you need Gelco-specific service in Forest Hills, call (516) 240-9612 for a written quote before anyone starts.

Why Forest Hills Residents Choose Us for Gelco Service
We’ve pulled cameras through more Gelco flues in Forest Hills than we can count, but the number isn’t the point. The point is that we know what a Gelco clay-tile liner looks like after a century of freeze-thaw cycling, and we know what it looks like after a bad conversion from coal to gas. Those are two different failures, and most sweeps treat them as one. Corrine Halstead, who runs our shop, grew up in Queens and spent nearly two decades running inspections across Jamaica and Forest Hills before founding this company. She learned building systems at New York City College of Technology in Brooklyn, and that training shows when a camera finds something the seller’s disclosure never mentioned.
Forest Hills homeowners call us for Gelco work because we write up exactly what the scope shows. A photo, a measurement, a number. No vague language about “deterioration” without a picture to prove it. Clause 4 of the Haven Standard requires a documented photo record on every job, and we’ve operated that way since 2009.
Common Gelco Chimney Cleaning Problems We Solve in Forest Hills
- Cracked clay tile liners along vertical joints. Forest Hills Gardens sits on soft historic brick and lime mortar from the 1910s-1930s, and every winter the temperature swings around 32°F repeatedly. Water gets into the tile, freezes, expands, and fractures the liner from the top down. We find these cracks during routine cleanings far more often in the Gardens than anywhere else in Queens.
- Oversized flues causing condensation and rapid creosote buildup. Most Gelco chimneys in Forest Hills were sized at 8×12 or 8×16 for coal furnaces. When those homes switched to gas in the 1950s-60s, the flues were left unlined. The cross-section is far too big for a modern gas appliance, so flue gases cool below condensation temperature before they exit. The result: acidic condensate eating mortar joints from the inside out.
- Mortared crowns spalling and losing bond. Gelco’s mortared crown assemblies absorb water from rain and snow, and after 100 winters in Forest Hills, that water has done its work. Crowns crack, lose adhesion to the brick, and let moisture migrate down the flue. We repoint and seal these crowns rather than rebuilding them when the tile below is still sound.
- Creosote accumulation from occasional fireplace use. Homeowners in Forest Hills Gardens who only light a fire a few times each season assume their chimneys stay clean. The opposite is often true. Oversized flues cool exhaust gases too quickly, and creosote condenses on the tile walls even with light use. We sweep based on what the camera shows, not a calendar.
- Backdrafting from flue-to-appliance mismatches. When a Gelco flue sized for coal vents a modern gas insert or high-efficiency boiler, the draft can reverse. We measure draft during cleaning and flag it when the numbers don’t support safe operation.

AfterGelco Service in Forest Hills: What Local Conditions Mean for Your Equipment
Here’s what changes the whole picture in Forest Hills, and it’s specific to this zip code. In Forest Hills Gardens, the Gelco chimneys were built with 8×12 or 8×16 clay flue tiles for coal furnaces. When those homes converted to gas in the 1950s and 60s, the flues were left unlined and oversized. We routinely find these tiles glazed with acidic condensate that has eaten away mortar joints from the inside. You won’t see this in Rego Park’s 1960s brick boxes or Fresh Meadows’ post-war construction, because those homes were never designed for coal. In Forest Hills Gardens, it’s the default condition. If you own one of these homes and you’re using the fireplace as it stands, you need a camera inspection before you light anything. Nothing we recommend comes without photo evidence you can see yourself.
Last month, our tech pulled a Level 2 camera down a Gelco flue on Ascan Avenue in Forest Hills Gardens and found three cracked clay tiles near the roofline, each with vertical fractures from freeze-thaw spalling. The homeowner had been told by another company to rebuild the whole chimney. Our Forest Hills Chimney Repair team repointed the eroded mortar joints, installed a properly sized stainless steel liner, and coated the crown with a breathable siloxane sealer. The fireplace drafts clean now, and those tiles are stabilized for another decade. The camera doesn’t negotiate, it just shows what’s there.
Gelco Models & Products We Service in Forest Hills
We work on the Gelco Standard Clay Tile Liner, the Gelco Multi-Flue Clay Tile System, and the Gelco Mortared Crown Assembly. That covers most of the original chimneys in Forest Hills Gardens, where multi-flue systems were common in the larger Tudor Revival homes. When a liner section needs repair, we use genuine Gelco clay tiles and matching refractory mortar wherever the original profile can be matched. Aftermarket tiles often differ slightly in diameter and create uneven flue walls that trap creosote. For crowns and caps, we prefer galvanized steel or copper components sized specifically to the Gelco flue dimensions. We recommend full liner replacement only when multiple tiles are cracked or the existing liner can’t support a HeatShield resurfacing. Our local stock covers the most common Gelco configurations, so Forest Hills turnaround is usually days, not weeks.

FAQs - Gelco Chimney Cleaning in Forest Hills
It’s freeze-thaw damage, not use. Water enters through the crown or brick, freezes during Queens winters, and the expanding ice fractures the clay tile. Forest Hills Gardens homes are especially prone because the original brick and lime mortar from the 1910s-1930s absorb water. Even an unused fireplace is at risk. The fix is a camera inspection to locate the cracks, then either repointing or a liner. Call (516) 240-9612 and we’ll show you the photos before quoting anything.
No, and any company that says otherwise is putting you at risk. Relining in New York City requires an NYC DOB permit, and we handle that as part of the job. Many out-of-borough sweeps don’t know this, and their work either fails inspection or leaves you exposed. We pull the permit, do the work, and document everything.
Because the flue was sized for coal or oil, not gas. Gas burns cooler and produces more water vapor, which condenses on the oversized tile walls as acidic liquid. That liquid eats the mortar joints. This is the single most common Gelco failure we see in Forest Hills Gardens homes converted in the 1950s-60s. The solution is usually a properly sized stainless steel liner. For an exact quote on your setup, call (516) 240-9612. Free estimates, written price before work.
Yes. Gelco’s mortared crown assemblies have a specific profile and material composition. Using the wrong mortar mix or the wrong sealant shortens the repair’s life. We use matching refractory mortar and, for waterproofing, a breathable siloxane sealer that lets moisture escape while keeping rain out. That combination is specific to century-old clay tile systems.
An insert changes the appliance draft requirements, and your original Gelco flue may not match. Installing an insert without relining the flue can cause backdrafting, carbon monoxide issues, and faster liner deterioration. We always verify draft and flue dimensions against the insert manufacturer’s specs before recommending anything, and we document the findings on camera. If you’re considering an insert in Forest Hills, call (516) 240-9612 first, we’ll tell you if the flue can support it and what relining would cost.
