Gelco Fireplace Services in San Francisco: What to Know First
We provide independent Gelco fireplace services throughout San Francisco, from routine gas fireplace tune-ups to firebox rebuilds on wood-burning units. Most Gelco jobs we see in the Richmond, Noe Valley, and Outer Sunset are completed in a single visit, with upfront pricing given before any work begins. We charge what the job warrants, no more, and we put our 90-Day Done Right Promise behind every repair in writing.
This page is for San Francisco homeowners who already know they own a Gelco fireplace, insert, or damper assembly and need a technician who understands the brand’s particular quirks. If that describes your situation, call (855) 408-5567. A live person answers, 24 hours a day.

How Gelco Products Fail - and How We Fix Them
- Gelco Pre-Fab Fireplace Units (model lines 36CF, 42CF, and the older 32CF series): The refractory panels in these factory-built fireboxes develop hairline cracks after repeated thermal cycling, especially in San Francisco’s damp climate where morning fog followed by evening firing creates more expansion stress than drier inland regions. We replace with Gelco-specified refractory or, when the unit is discontinued, fabricate a panel match that meets the original UL listing. Warren Eckhart has rebuilt three of these in the Outer Sunset alone where the original installer had used generic cement board that failed within two seasons.
- Gelco Gas Fireplace Inserts (GVF series and early GV42 models): The pilot assembly on GVF units manufactured between 2008 and 2014 is prone to soot accumulation that mimics a failed gas valve. We see this misdiagnosed constantly. Our techs pull the burner tray, clean the pilot orifice with the correct size drill bit, and test flame rectification with a microamp meter before condemning any component. If the gas valve truly has failed, we source the Robertshaw or White-Rodgers equivalent that Gelco specified, not a universal swap that voids what warranty remains.
- Gelco Top-Sealing Dampers (the cast-aluminum throat damper line): The stainless steel cable on these dampers frays where it passes through the chimney wall, particularly on San Francisco’s steep-pitched Victorian roofs where lateral wind load is higher. We replace the cable with OEM Gelco specification or, when the frame itself has corroded from salt air near the Pacific, we fabricate a transition to a Lock-Top or Lyemance damper that seals tighter and carries a longer service life.
- Gelco Wood-Burning Fireplace Doors (GD42 and GD36 framed assemblies): The tempered glass panels in these doors develop edge fractures from improper installation, specifically when the original installer failed to allow for frame expansion. We measure the opening ourselves, order glass to Gelco’s exact temper specification, and install with high-temperature silicone gaskets that compress properly. The “rattle” owners complain about is almost always this gasket failure, not the glass itself.
- Gelco Chimney Caps (stainless and copper models): The mesh screen on Gelco’s standard cap welds can separate after a decade of marine air exposure, allowing squirrel and raccoon entry that owners mistake for a damper problem. We inspect with a camera to confirm the flue is clear, then either re-weld the existing cap or replace with a Gelco-specified model that uses heli-arc construction rather than spot welds. In the fog belt near the Great Highway, we see this failure mode twice as often as in the Mission District’s drier microclimate.
Our Gelco Fireplace Services Process
- 1
You call, a live person answers. We ask the model number if you have it, the symptoms, and when you last had service. We schedule a window that day or the next.
- 2
Level-2 camera inspection on arrival. Our technician documents the flue, firebox, and mechanical components with photos you can see on the spot. We deliver a plain-English verdict: what is wrong, what caused it, what it costs to fix.
- 3
Parts decision with full disclosure. If your Gelco unit is under warranty or we can source OEM at reasonable lead time, we do so. If the part is obsolete or OEM pricing is punitive, we explain the quality aftermarket equivalent from our DuraFlex, HeatShield, or Copperfield supply chain and why it meets the application.
- 4
The repair, done once. Our background-checked, uniformed techs carry most Gelco service items on the truck. We complete most jobs in a single visit, test every function, and clean the work area before we leave.
- 5
Written guarantee, no arguing. You receive the 90-Day Done Right Promise in writing. If the flue isn’t right, the fire isn’t right. Everything else follows from that.

FAQs
No. As an independent Gelco service provider, our repairs do not void manufacturer warranties provided we use OEM or equivalent-specification parts and follow installation guidelines. We document every part source and procedure so you have records if a warranty question ever arises. Call (855) 408-5567 if you need help understanding what coverage remains on your unit.
Most common Gelco service parts - pilot assemblies, damper cables, standard refractory panels - are on our trucks or available next-day through our San Francisco supply house. Discontinued units sometimes require fabrication, which we typically complete within three to five business days. We’ll tell you honestly which situation applies before we start.
For Gelco units under fifteen years old, repair is almost always the better value, particularly for gas inserts where the venting infrastructure represents most of the installed cost. For wood-burning pre-fab units over twenty years old with cracked refractory and rusted frames, replacement sometimes makes sense. We give you both numbers and our recommendation, with no pressure either way. Call (855) 408-5567 for a free assessment.
Yes, when the existing firebox and flue meet current San Francisco building code for the conversion type you want - direct vent insert, vented gas logs, or sealed gas insert. We pull the permit, run the gas line coordination with a licensed plumber if needed, and complete the installation with a Level-2 inspection and written certification. Not every Gelco unit qualifies; we’ll tell you straight if yours doesn’t.
If the damper opens partially or feels gritty when you operate the handle, the cable is likely fraying. If the handle moves freely but the damper plate doesn’t respond, the frame pivot has corroded or the plate itself is warped. We diagnose this with a camera inspection so you know before we quote. Call (855) 408-5567 and we’ll schedule a look.
