Gelco systems are common in Montgomeryville Gelco service areas and Lansdale for good reason. The brand’s stainless steel caps and flexible liners were specified by a lot of local contractors during the 2000s and 2010s, and we encounter them regularly on the older homes that dominate this borough. Those Victorian twins and foursquares near Main Street and the train station corridor often run Gelco multi-flue caps over coal-era chimneys that were converted to gas or oil decades ago. The combination of original masonry and modern venting hardware creates specific maintenance demands that generic sweep companies miss.

Corrine Halstead, our owner, trained in building systems at New York City College of Technology before spending nearly two decades doing chimney work across Montgomery County. Her crew 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. The camera doesn’t guess. Neither do we.

Why Trust Level Two Chimney Lansdale for Your Gelco Chimney Cleaning?

We’ve worked on hundreds of Gelco systems in Lansdale, Souderton Gelco service areas, and the surrounding boroughs. That volume matters because Gelco products have specific quirks that only show up after repeated exposure. The stamped mesh screens on older Gelco single-flue caps, for instance, corrode in a predictable pattern after seven to ten years of Montgomery County freeze-thaw cycling. We’ve seen it enough times to know the difference between surface oxidation and structural failure that’ll let starlings build a nest in your flue by March.

Our technicians carry Gelco-compatible replacement parts on the truck, and when genuine Gelco components are discontinued or backordered, we source high-quality aftermarket equivalents through our Haven buying network. Every repair decision is documented with photos and explained in plain terms: condition, clearance, cost. Clause 1 of the Haven Standard requires a written price, written scope, and written warranty before anyone starts work. No exceptions.

We’re independently owned and operated, not a franchise. Background-checked, uniformed technicians. License information on every page. A text when your tech is on the way. And if we don’t get it right, we make it right - that’s the 365-Day Done Right Promise, stamped on every job.

Common Gelco Chimney Cleaning Problems We Fix in Lansdale

• Corroded cap mesh screens on Gelco single-flue and multi-flue models. The stamped stainless mesh on Gelco caps looks rugged when new, but Lansdale’s inland position subjects it to aggressive freeze-thaw cycling from November through March. Moisture gets into the mesh pores, expands on freezing, and eventually causes the screen to collapse inward. We find this most often on homes within a few blocks of the Main Street corridor, where the original coal-era chimneys are tallest and catch the most weather. A collapsed screen means birds, squirrels, and leaf debris enter the flue unimpeded. We replace with Gelco-compatible mesh or full cap units depending on corrosion severity.
• Pinhole cracks and connector separation in Gelco flexible stainless liners. Gelco’s flexible liners, both insulated and uninsulated, develop stress fractures at the appliance collar after repeated thermal cycling. In Lansdale, this accelerates when an oversized coal-era flue runs too cool post-conversion to gas or oil, causing condensation to pool at the liner’s low points. The moisture combines with combustion acids and eats pinholes from the inside out. We camera-scan the full liner length to map the damage. Spot repairs are possible if the breach is localized; full replacement gets recommended when the liner shows multiple failure points or any separation from the appliance connector.
• Shifted multi-flue caps with compromised crown seals. Gelco multi-flue caps mount with bracket systems that can loosen as the crown mortar deteriorates beneath them. Lansdale’s century-old brick chimneys are particularly vulnerable here - the original crown was often poured with weak concrete mix over a century ago, and modern polyurethane sealants eventually lose adhesion. When the cap shifts, even a quarter-inch gap becomes a water funnel. We were called to a home in Lansdale where the owner’s Gelco multi-flue cap had shifted after a nor’easter, and water was tracking down the flue and staining the firebox. Our tech removed the old cap, found the mounting brackets had stripped out of the crown, and installed a new stainless Gelco-compatible multi-flue cap with fresh anchors and a bead of polyurethane sealant. We also coated the crown while we were up there, and the homeowner hasn’t seen a drop since.
• Failed insert gaskets and warped baffle plates in Gelco direct-vent units. Gelco fireplace inserts rely on fiberglass door gaskets and steel baffle plates to maintain combustion efficiency and prevent smoke spillage. After ten to fifteen years of heating seasons, the gaskets compress and the baffles warp from overfiring or from homeowners running the unit with the glass door cracked open. The first symptom is usually a smoke smell on startup - the insert is pulling room air through failed seals instead of maintaining a sealed combustion path. We inspect gasket compression with a feeler gauge and check baffle plate flatness against a straightedge. Replacement gaskets are stocked; baffle plates are ordered to spec.
• Crown coating failure on Gelco-protected masonry chimneys. Gelco’s crown coating system is a legitimate waterproofing product, but it requires application over sound substrate. In Lansdale, we frequently find it applied over spalling concrete or hairline cracks that weren’t repaired first. The coating traps moisture underneath, accelerates freeze-thaw damage, and delaminates within two to three years. Our approach: camera and visual inspection of the crown first, mechanical repair of cracks and spalls, then coating application only when the substrate is sound. This is standard under Haven Standard Clause 4 - document before you treat.

Gelco Parts & Our Repair-vs-Replace Approach

We stock genuine Gelco replacement parts where the supply chain still supports them: cap mesh screens, multi-flue mounting brackets, insert gasket kits, and flexible liner connector collars. For discontinued components - certain pre-2010 cap sizes and early insert baffle configurations - we use aftermarket equivalents from Olympia Chimney and Famco that meet or exceed original Gelco specifications. These are procured through our Haven buying network, not generic hardware-store stock.

Our repair-versus-replace decision is straightforward. If your Gelco cap has localized mesh corrosion but sound frame and mounting points, we replace the mesh. If the frame is warped or the mounting flange is cracked, we recommend a full cap - and we show you the crack on camera before asking for a decision. Same principle applies to liners: spot repair with a stainless patch and high-temp sealant for single breaches; full reline when the damage pattern indicates systemic failure. No upsell. Just photos, readings, and a written price. Call (267) 327-4785 for a free estimate.

Our Gelco Service Process - Step by Step

1. 1
   Diagnosis with camera-scan documentation. We run a chimney camera the full flue length on every Gelco service call. For cap and crown work, we photograph the mounting condition and crown integrity from the roof. For insert service, we inspect the firebox, gasket seals, and baffle plate with the unit cold, then hot-test for draft and spillage. Clause 4 of the Haven Standard requires this photo record - we’ve done it on every job since 2009.
2. 2
   Written scope and price before work. You get a written document: what we found, what we recommend, what it costs, and what the warranty covers. No verbal quotes. No “we’ll figure it out when we start.” Clause 1 of the Haven Standard - have it in writing.
3. 3
   Repair or installation with Gelco-compatible parts. Our trucks carry common Gelco cap sizes, liner connectors, and insert gaskets. For specialty orders, we source through Haven’s network and schedule return installation, typically within 48 to 72 hours.
4. 4
   Post-work testing and documentation. Caps get water-tested with a hose spray from multiple angles. Liners get a final camera run to verify seal integrity. Inserts get combustion analysis and draft measurement. You receive the complete photo record and written warranty before we leave.

FAQs - Gelco Chimney Cleaning Service in Lansdale

Is Level Two Chimney Lansdale authorized by Gelco?

No. We are an independent service provider with no affiliation, authorization, or endorsement from Gelco. Our expertise comes from hands-on work on hundreds of Gelco systems across Lansdale and Montgomery County, not from a manufacturer certificate. We use genuine Gelco parts where available and quality aftermarket equivalents where they’re not.

Can you replace just the mesh screen on my Gelco chimney cap, or do I need a whole new cap?

We can replace the mesh screen alone if the cap frame, mounting flange, and lid hinge are sound. We determine this by removing the cap and inspecting for frame warping, thread damage in the mounting holes, and hinge pin wear. If the frame is compromised, a new cap is the only repair that’ll last through another Lansdale winter. Call (267) 327-4785 and we’ll show you the condition on camera.

My Gelco flexible liner was installed about 12 years ago - how do I know if it’s still safe?

A 12-year-old Gelco flexible liner needs a camera inspection to assess its condition. We look for pinhole corrosion, separation at the appliance connector, and evidence of previous chimney fire damage (discoloration, warping, or metal thinning). The inspection takes about 45 minutes and includes a full photo record. If the liner passes, we document it. If it doesn’t, we give you a written replacement price. Call (267) 327-4785 to schedule.

Why does my Gelco insert smell like smoke when I first light it?

Smoke smell on startup usually means failed door gaskets or a warped baffle plate. The insert is pulling room air through compromised seals instead of maintaining its sealed combustion path. We check gasket compression with a feeler gauge and baffle flatness with a straightedge. Replacement gaskets are a same-day fix; baffle plates typically require ordering to your insert’s serial number configuration.

Can you waterproof a Gelco masonry chimney without trapping moisture inside?

Yes, but only after verifying the crown and mortar joints are sound. We camera-inspect and visually assess the crown first, repair any cracks or spalls mechanically, then apply crown coating or breathable masonry sealer. Applying waterproofing over damaged substrate traps moisture and accelerates freeze-thaw damage - we won’t do it, and we’ll show you why on camera.

Do you carry Gelco-specific caps and liners on the truck, or do I have to wait for an order?

Our Lansdale trucks stock the Gelco cap sizes and liner diameters most common in borough homes: 6-inch and 7-inch flexible liners, and multi-flue caps for standard 9×13 and 13×17 crowns. Less common sizes - 4-inch liners for small gas appliances, or oversize caps for paired flues - are measured on-site and ordered through our Haven network, typically installed within 48 to 72 hours. Call (267) 327-4785 and we’ll confirm availability for your specific configuration.
