A standard Gelco annual sweep and inspection runs $89-$195 depending on access and buildup, and we do not recommend work you cannot see for yourself in our camera photos. This page is for Gelco owners in Ewing who want their flue cleaned, inspected, and documented by technicians who know the difference between a Gelco UltraPro cap and a builder-grade knockoff.

How Gelco Products Fail - and How We Fix Them

• Gelco chimney caps corrode at the mesh weld points. The Gelco Multi-Flue cap series uses stainless mesh that holds up well, but the spot welds where mesh meets frame fatigue after 12-15 winters of Mercer County freeze-thaw. We see this most on Ewing homes near the Delaware River where wind-driven moisture accelerates the cycle. We remove the cap, document the weld failure with photos, and install a replacement Gelco cap or an Olympia Chimney equivalent with fully seam-welded construction.
• Gelco top-sealing dampers lose their silicone seal in sustained cold. The Gelco Lyemance and Lock-Top damper lines rely on a silicone rubber gasket that contracts and hardens below 20°F. Ewing sees 10-15 nights that cold each January. The damper still operates, but the seal leaks conditioned air and lets downdrafts carry soot smell into the living room. We inspect the gasket with a borescope, replace it with OEM Gelco gasket material or a HeatShield-compatible upgrade, and test the seal with a smoke pencil.
• Gelco pre-fab chimney chase covers pool water at the corners. The Gelco chase cover line with stamped drip edges sheds water fine until debris accumulates in the corners of rectangular chases. In Ewing’s mature neighborhoods off Scotch Road, oak leaf litter is the main culprit. Water pools, rusts the corners from underneath, and stains the chase siding. We clean the chase top, treat early surface rust, replace the cover if pitting has started, and verify the new cover has cross-breaks to shed debris.
• Gelco flue liners shift at the collar joint in clay-lined chimneys. The Gelco stainless liner system with the adjustable top collar works well when installed with proper tension. But in Ewing’s 1950s-1970s ranch homes with offset flue tiles, the collar can work loose over five to seven years of thermal cycling. We spot this during camera inspection when the liner shadow shows a gap at the top course. We reset the collar, add a locking band if the original installer omitted one, and document the repair with before-and-after photos.
• Gelco spark arrestor screens clog with creosote in airtight stoves. The fine mesh on Gelco UL-listed spark arrestors traps more creosote than coarser aftermarket screens, which is the point, but owners who burn unseasoned hardwood or run their stove on low air settings fill the mesh faster than expected. We remove and ultrasonic-clean the screen during the sweep, check the draft with a manometer, and flag the burn practice if the creosote is glazed and tarry rather than flaky.

Our Gelco Chimney Cleaning & Sweep Process

1. 1
   Call intake. A live person answers, notes your Gelco model if you know it, and schedules a window. No app, no callback queue.
2. 2
   Arrival and setup. Our technician arrives in a marked van, confirms the upfront price, and lays drop cloths from the door to the hearth. We check the Gelco cap model and condition before touching anything.
3. 3
   Level 1 or Level 2 inspection. We run a camera up the flue, photograph every course and joint, and note any Gelco-specific wear patterns. You see the images on our tablet as we find them.
4. 4
   Sweep and component service. Rotary brushes remove creosote and soot. We service the damper, clean or replace the spark arrestor screen, and address any cap or chase cover issues with OEM Gelco parts or professional-grade equivalents from Olympia Chimney or Famco.
5. 5
   Testing and documentation. We test draft, damper seal, and cap integrity. You receive a written report with photos, a plain-English verdict, and any recommendations ranked by urgency.
6. 6
   Cleanup and guarantee. We vacuum, remove drop cloths, and leave the work area as we found it. The job is covered by our 90-Day Done Right Promise, in writing, no arguing.
