How Gelco Products Fail - and How We Fix Them

• Gelco pre-fabricated chimney chase covers (Model 1000 and 2000 series) develop pinhole rust at the welded seams after 12 to 18 years in Leesburg’s freeze-thaw cycle. The galvanized coating holds up well inland, but the combination of wood-burning acidity and our wet winters attacks the seam welds first. We pull the cover, document the rust pattern with photos, and install a Gelco replacement or upgrade to a stainless chase cover from Olympia Chimney if the chase framing is still sound.
• Gelco top-sealing dampers (Model TD series, especially TD-1435 and TD-1842) accumulate creosote on the silicone seal gasket faster than cast-iron throat dampers. The gasket hardens, the damper loses its airtight seal, and you feel a cold downdraft even when it is “closed.” During a sweep, we remove the damper assembly, clean the gasket seat with non-abrasive solvent, and replace the gasket with OEM Gelco parts or a compatible high-temp silicone from Famco if the frame geometry allows.
• Gelco stainless flue liners (ProFlex and SmoothWall series) can separate at the collar joint where the liner meets the appliance adapter, particularly in systems that see frequent hot-to-cold cycling. We spot this with a Level 2 camera inspection - the gap is often invisible from below - and re-secure with a Gelco compression collar or, if the liner is ovalized, transition to a DuraFlex rigid liner section at that joint.
• Gelco chimney caps (Model CG and WG series with mesh sides) clog with creosote flakes and ash in homes that burn unseasoned oak or hickory, common in Leesburg because of the hardwood supply from western Loudoun County. The mesh spacing is finer than some competitors, which protects against animal entry but requires more frequent cleaning. We remove the cap, soak and brush the mesh, and advise on wood moisture content - 20% or below - to extend the interval.
• Gelco firestop radiation shields in manufactured chimney systems can shift or compress if the original installer used too few support brackets across a long vertical run. We find this during a Level 2 inspection when the camera catches light leak around the shield perimeter. We re-seat the shield with proper Gelco support hardware and document the repair for your insurance file.

Our Gelco Chimney Cleaning & Sweep Process

1. 1
   Call and schedule. A live person answers, asks what you are burning and how often, and schedules a arrival window. Russell Haines has a phrase: “Tell me what you are burning and how often, and I can tell you what your chimney looks like before I even climb up.”
2. 2
   Arrival and identification. Our background-checked, uniformed technician confirms your Gelco model from the data plate or physical characteristics, then lays down protection and reviews the upfront price.
3. 3
   Inspection and documentation. We perform the agreed Level 1 or Level 2 inspection, photographing every stage. For Gelco systems, we pay particular attention to chase cover seams, damper gasket condition, and liner collar integrity.
4. 4
   Cleaning and repair. We sweep with brushes sized to your Gelco flue diameter, remove creosote and soot, and complete any minor repairs - gasket replacement, cap cleaning, chase cover resealing - with OEM Gelco parts or professional-grade equivalents from DuraFlex, HeatShield, or Famco.
5. 5
   Testing and final documentation. We run a draft test, verify damper operation, and provide photos and a plain-English verdict. If we found something that can wait, we say so. If it needs attention, we explain exactly why.
6. 6
   Cleanup and guarantee. We leave the work area as we found it. Every job is backed by our 90-Day Done Right Promise - in writing, no arguing.
