Gas Valve Repair & Replacement
The gas valve is the part standing between the supply line and your living room — when it sticks, weeps, or stops responding to its thermostat circuit, replacement isn’t a maybe. It’s also not a DIY: this is the most consequence-dense part on the fireplace.
Diagnosed first — valves get blamed unfairly
Half the “bad valves” we’re called for are actually weak thermopiles or wiring faults that mimic valve failure. We test the millivolt circuit and the valve’s response before condemning it — an honest hour that regularly saves customers the bigger bill.
Replaced like gas work should be
When it is the valve: matched replacement (millivolt, electronic, or manual safety valve per your system), connections made with proper sealant and a sediment trap, every joint leak-tested, and a full ignition-cycle verification. You watch it light, hold, and shut off correctly before we call it done.
The Gas Visit
- Millivolt circuit testing before replacement
- OEM-matched valve sourcing
- Leak test at every connection
- Ignition cycle and safety shutoff verification
- Same-visit replacement for common systems
Common Questions
The wall key is getting stiff to turn. Wait or replace?
Stiff means internal corrosion has started — replace on schedule, not on emergency. A valve that seizes mid-season turns a planned visit into a no-fireplace January.
I smell a faint gas whiff at the fireplace. Valve?
Treat any gas smell as urgent: shut the supply key, ventilate, and call. It may be the valve, a fitting, or the pilot tube — our leak detection finds it precisely. Don’t run the fireplace until then.
