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.
Gelco Chimney Cleaning in Souderton, PA | Level Two Chimney Lansdale
We provide Chimney Cleaning & Sweep in Souderton for independent Gelco service across the historic borough, where century-old multi-flue masonry demands more than a standard sweep. Most calls here involve Gelco liners installed during coal-to-gas conversions that are now failing in shared chases damaged by freeze-thaw cycles. For a free written estimate, call (267) 327-4785 - we answer live, 24/7.
Why Souderton Residents Choose Us for Gelco Service
We’ve worked on Gelco systems in Souderton since 2009. Corrine Halstead, our owner, spent the better part of two decades doing chimney work across Montgomery County after training in building systems at New York City College of Technology. Her crew has serviced wood-burners and gas inserts throughout the area, including older colonials where creosote buildup is rarely a surprise but always worth showing the homeowner on camera.
We are not authorized, partnered with, or endorsed by Gelco. We’re an independent service that handles their equipment weekly and stocks genuine Gelco replacement components alongside high-quality aftermarket equivalents that meet or exceed UL 1777. Our Gelco sales & service covers every model line we encounter in the field, and our Souderton service area runs from the borough core to the surrounding townships.
Every visit includes an NFPA 211 Level 2 inspection with camera documentation - Clause 4 of the Haven Standard, unchanged since we started it in 2009. You get photos, a written scope, and a written price before anyone picks up a tool. The 365-Day Done Right Promise applies to every job.
Common Gelco Chimney Cleaning Problems We Solve in Souderton

- Uninsulated Gelco UltraPro liners in oversized soft-brick flues. Souderton’s coal-era chimneys were built larger than modern gas appliances need. When a Gelco liner was dropped in without proper insulation, condensation forms on the cold outer wall, rusts the stainless steel from the outside in, and stains the surrounding brick. We see this on Front Street twins and Railroad Avenue row homes alike.
- Gelco cap and crown assemblies on deteriorating mortar washes. The borough’s 30-plus annual freeze-thaw cycles pulverize the thin mortar beds beneath multi-flue caps. Water gets behind the Gelco cap, corrodes the liner top, and accelerates spalling on the shared chase brick. A cap replacement without crown repair is money thrown away here.
- Separated liner joints in uninsulated exterior chases. Souderton’s winters flex Gelco liner joints until they gap open. Flue gases leak into adjacent dormant flues - the ones that served kitchen ranges or parlor stoves a century ago - and find their way into living spaces through old thimble holes.
- Mismatched Gelco insert adapters in 1880s-1930s fireplace openings. Original coal fireplace throats are oversized for modern gas insert flue collars. The adapter gaps draw soot and creosote from inactive flues into the active vent path, creating a Class III creosote condition that standard sweeping won’t reach.
- Moisture infiltration through abandoned flue openings. When one flue in a three-flue Souderton chimney was converted to gas and the others were capped informally, those caps often fail. Rain enters the dormant flues, saturates the shared masonry, and rusts the active Gelco liner from the exterior - a problem invisible until the camera goes up.
Before
AfterGelco Service in Souderton: What Local Conditions Mean for Your Equipment
Souderton’s original coal-era chimneys were built with two or three flues in a single masonry chase, so when one flue was converted to gas and the others were abandoned, the shared brickwork continued to absorb moisture and freeze-thaw damage that silently compromised the active Gelco liner. This is distinct from newer single-flue townships like Franconia and Salford, where dormant flue cross-contamination is rarely a factor.
On a Souderton Chimney Repair call near Summit Street, we inspected a Gelco UltraPro liner in an 1890s twin that had been converted from coal to gas; the Level 2 camera showed the liner joints pulling apart above the roofline and heavy spalling on the shared chase. We rebuilt the crown, repointed the soft-brick joints, and installed a properly sized multi-flue cap to seal the two abandoned flues, then re-seated the Gelco liner with new insulation. The homeowner’s draft improved immediately, and the adjacent flues stopped leaking soot into the living space.
The camera doesn’t guess. Neither do we.
Gelco Models & Products We Service in Souderton

We handle the full Gelco product range found in southeastern Pennsylvania homes: UltraPro flexible stainless steel liner kits, ProFit insulated rigid liner sections, the Chimney Cap and Crown product line, and Fireplace Insert connection kits. Our truck stocks the most common Gelco collar adapters, termination caps, and flex-to-rigid transition pieces, so most Souderton repairs don’t wait on parts.

FAQs - Gelco Chimney Cleaning in Souderton
Yes. In Souderton’s multi-flue chimneys, abandoned flues routinely leak moisture and combustion byproducts into active ones through shared masonry. Our Level 2 camera inspects all flues in the chase, not just the one in use. Call (267) 327-4785 to schedule - estimates are free.
The cap isn’t the root problem. Freeze-thaw damage beneath it destroys the mortar wash, letting water pool against the cap base and wick into the liner top. We replace the cap only after rebuilding the crown and repointing the soft-brick joint - otherwise you’re buying the same cap twice.
Yes. We use polypropylene brushes sized to the liner diameter, never steel on stainless. For Class III glazed creosote, we apply PSC 401 first, then mechanical cleaning - the method specified for flexible liners. The camera confirms liner integrity before we finish.
Very common. Original coal fireplace throats in Souderton’s 1880s-1930s stock are 8-10 inches larger than modern gas insert collars. The adapter gap draws air and soot from adjacent dormant flues. We fabricate transitional collars or recommend a properly sized ProFit rigid section when the masonry allows.
Rarely. Spalled soft brick and open joints are repairable with targeted repointing and crown reconstruction. We salvage the Gelco liner whenever the camera shows intact stainless and proper insulation. Full rebuilds are reserved for structural failure or liner collapse - we’ll show you the difference on screen before quoting either. Call (267) 327-4785 for a free written assessment.
