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 Lansdale, PA | Level Two Chimney Lansdale
Gelco chimney cleaning in Lansdale typically runs $180-$340 for a standard sweep with Level 2 camera inspection, and we quote the exact price in writing before any work starts. What makes our Gelco service different here is Lansdale’s unusual concentration of coal-era multi-flue chimneys - three and four flues packed into one brick stack, often misidentified by homeowners who don’t know which vents the furnace, which vents the water heater, and which was capped off in 1962. We figure that out first, with smoke testing and a camera run, then clean what’s actually in use. Call (267) 327-4785 for a free written estimate.
Why Lansdale Residents Choose Us for Gelco Service
We’ve provided Chimney Cleaning & Sweep in Lansdale for Gelco liners, caps, and dampers since 2009 - more than 38,000 chimney jobs all told, every one with a written price before work started and a documented photo record when it was done. Corrine Halstead, who leads our crew, trained in building systems and HVAC technology at New York City College of Technology before spending the better part of two decades on Montgomery County chimneys. Her team has serviced wood-burners and gas inserts throughout Lansdale, including older colonials near the Merrick Road corridor, where creosote buildup is rarely a surprise but always worth showing the homeowner on camera.
We know the Gelco product line because we encounter it constantly in Lansdale’s housing stock: stainless flexible liner kits from oil-to-gas conversions, multi-flue caps on four-flue brick stacks, single-flue caps with spark screens on decorative fireplaces. We’re an independent chimney service - not affiliated with, authorized by, or endorsed by Gelco - and we treat every Gelco-equipped flue on its own merits, drawing on our Chimney Repair in Lansdale experience. The camera doesn’t guess. Neither do we.
Our Gelco sales & service covers the full product range, and we stock OEM-compatible cap screens, fasteners, and clamp components for fast turnaround. Every job carries the 365-Day Done Right Promise, and we offer a free second opinion on any competitor’s written estimate. Calls are answered by a live person, 24 hours a day.
Common Gelco Chimney Cleaning Problems We Solve in Lansdale
- Glazed creosote on Gelco liners in oversized coal-era flues. Gelco stainless flexible liners installed during gas conversions in Lansdale’s Victorian twins and rowhouses often sit inside flues that were built for coal. The oversized diameter runs too cool, so moisture and creosote condense on the liner wall - especially in the top third, where the flue temperature drops fastest. We see this regularly in homes off West Main Street. A standard brush won’t touch glazed deposits; we assess the class of creosote by camera before selecting the right removal method.
- Rusted Gelco cap fasteners from freeze-thaw crown damage. Lansdale’s inland position subjects century-old brick chimneys to aggressive freeze-thaw cycling from November through March. Water infiltrates cracked crown mortar, wicks down past the cap collar, and rusts the Gelco cap’s fasteners and screen frame. We replace with stainless hardware and document crown condition with photos - Clause 4 of the Haven Standard requires the record.
- Debris-packed multi-flue cap screens blocking misidentified flues. On three- and four-flue Gelco caps common near the Lansdale train station, leaves and debris pack the screen bays. The bigger problem: the homeowner often doesn’t know which flue serves which appliance. We’ve found furnace flues completely blocked while the decorative fireplace flue - unused for decades - was the only one drawing. Carbon monoxide risk is real when combustion gases can’t escape. We smoke-test before removing any cap.
- Degraded Gelco liner insulation from improper sweep technique. Previous sweeps sometimes ran overly aggressive brushes that tore the insulation wrap on Gelco liner kits, leaving uninsulated sections that can’t maintain flue temperature. In Lansdale’s cool-running oversized chimneys, this accelerates creosote formation dramatically. We camera-scan for insulation integrity and quote repair or replacement - never sweep around a known defect.
- Top-sealing damper failure after years of moisture exposure. Gelco top-sealing dampers on Lansdale’s older fireplace flues corrode where crown leaks let water pool on the damper frame. The gasket degrades, the chain seizes, and the homeowner loses the energy-saving seal that justified the original installation. We assess whether the damper body is salvageable or if replacement makes more sense than repeated repair.

AfterGelco Service in Lansdale: What Local Conditions Mean for Your Equipment
Lansdale’s borough core grew rapidly during the North Penn Railroad boom of the 1880s-1920s, leaving a dense concentration of Victorian and early 20th-century homes with original multi-flue masonry chimneys built for coal-burning furnaces. When those systems converted to oil or gas, the oversized flues stayed - and that’s where Lansdale’s Gelco story gets specific. In the blocks around the Lansdale SEPTA/Amtrak station and the Main Street corridor, three- and four-flue coal-era chimneys routinely hide the furnace flue behind decorative fireplace flues that were capped or bricked over decades ago. This configuration doesn’t exist in newer Montgomery Township construction just outside the borough. Before we remove any Gelco cap or run a brush, we smoke-test or draft-test every flue. Cleaning the wrong one wastes your money. Missing a blocked active flue risks your life. Our crew carries labeled flue maps on every multi-flue job - taped inside the basement door when we’re done, so the next technician (ours or anyone else’s) knows what they’re looking at.
Gelco Models & Products We Service in Lansdale
We work on the full Gelco line still found in Lansdale service area homes:
- Gelco stainless steel flexible chimney liner kits - commonly installed during oil-to-gas conversions in Lansdale’s Victorian twins and rowhouses; we clean, inspect by camera, and repair or replace sections as needed
- Gelco multi-flue chimney caps - for masonry chimneys with three or four clay-tile flues; we stock OEM-compatible screens, fasteners, and clamp components
- Gelco single-flue chimney caps with spark screens - on older Lansdale fireplace flues; we replace degraded screens and corroded frames
- Gelco top-sealing damper assemblies - assess, repair, or replace depending on corrosion and gasket condition
We use quality aftermarket stainless liner sections when an exact Gelco match isn’t available - the flue doesn’t care about the brand on the box.

FAQs - Gelco Chimney Cleaning in Lansdale
Yes. We smoke-test or draft-test every flue before removing the cap. On a late-Victorian twin off West Main Street near the train station, our crew found a Gelco multi-flue cap over four clay-tile flues, but the homeowner couldn’t tell us which one vented the gas furnace. We ran a smoke test, identified the furnace flue as the rear-most tile, swept heavy glazed creosote out of it, and found the front decorative fireplace flue was packed solid with a leaf nest under the Gelco screen bay - we cleared it, replaced two rusted cap fasteners, and left the family with a labeled flue map taped inside the basement door. Call (267) 327-4785 to schedule.
Your flue is probably oversized for the appliance. Gelco liners installed in Lansdale’s coal-era chimneys often sit inside brick passages built for much higher exhaust temperatures. Gas furnaces run cooler, so the flue wall stays below the dew point longer, and moisture plus combustion byproducts condense into creosote faster than in a properly sized system. We measure flue temperature and draft during our Level 2 inspection and tell you plainly if the liner diameter matches the appliance output. Call (267) 327-4785 for a camera inspection - estimates are free.
Yes. Lansdale’s pronounced freeze-thaw cycling from November through March pushes water into crown mortar joints, expands it, and cracks the seal where the Gelco cap collar meets the brick. Water then wicks down past the collar and rusts the fasteners. It’s predictable, inspectable, and fixable - but not if it’s ignored until the cap loosens or the screen falls in. We document crown condition with photos on every visit and quote repair before the damage reaches the flue liner. Call (267) 327-4785 for an inspection.
Yes. We are an independent chimney service - not affiliated with, authorized by, or endorsed by Gelco. We know Gelco products because we encounter them daily in Lansdale’s housing stock, and we stock OEM-compatible parts for common repairs. When an exact Gelco match isn’t available, we use quality aftermarket components that meet or exceed the original specifications. The Haven Standard requires us to document what we used and why, and to warranty our work for 365 days regardless of brand. Call (267) 327-4785 with questions about your specific Gelco setup.
A sweep without a camera is a guess. NFPA 211 Level 2 requires a visual inspection of all accessible flue surfaces - which in practice means a camera scan. In Lansdale’s century-old multi-flue chimneys, we’ve found cracked clay tiles, missing mortar, and uninsulated liner sections that no flashlight look would catch. Clause 4 of the Haven Standard requires a documented photo record on every job for exactly this reason. The inspection is included in our standard sweep price; skipping it saves nothing and risks missing a defect that could let carbon monoxide into living space or lead to a chimney fire. Call (267) 327-4785 to book - estimates are free.
