Most Lyons no-light calls trace back to elevation — a pilot that will not stay lit, a thermocouple working too hard in thin air, or a unit never adjusted for the altitude it lives at. We find the exact cause on the spot.
Repair, cleaning, inspection, installation and maintenance for Lyons — gas units adjusted for elevation, wood fireplaces and stoves cleaned and checked, and cabins opened up safely after months sitting empty.
RepairFireplace Repair
Any fireplace, any failure — diagnosed first, then fixed with the right parts. In Boulder County we see the pattern constantly: a unit that sat idle in a second home, then failed on the first cold night.
Thermopile, thermocouple, valve or board — tested at your elevation, and replaced only if it failed. Pilot that won't stay lit, dead remote, weak or lazy flame: gas systems diagnosed safely and repaired to code.
Soot, dust and that stale closed-up smell removed from the firebox, glass and burner — the clean that clears the stale, closed-up smell out of a cabin firebox that sat shut for months.
Firebox, flue, venting and controls checked end to end, with a plain-language report. At elevation we also check the altitude setup, venting and snow damage most inspections skip.
A new gas fireplace or an outdoor fire feature, done right: sizing, venting, gas and electric runs, finishing — one crew, start to first fire. We handle the whole job — unit, venting, gas line, electric and finish work, adjusted for altitude.
The annual service that keeps a Lyons gas fireplace lighting first try: full clean, burner and pilot service, safety sensors tested, and a test fire before we leave. Fifteen checkpoints, the altitude setup verified, and every sensor tested — done in one visit.

Local conditions
Lyons fireplaces have mountain problems
A fireplace in Lyons works at elevation, in dry cold and wide temperature swings few other regions see. Altitude, pine smoke, snow and long idle months in second homes do the damage here — this is what we check on every visit.
Altitude changes the burn
Gas burns differently in thin air. At Lyons's elevation, pilot flames run weaker, thermocouples work harder, and venting has to be set up for altitude — a unit adjusted for sea level will soot, struggle and quit early. We check the altitude setup on every gas call, not just the broken part.
Wildfire smoke days
Late-summer smoke changes how Lyons burns. On bad air days, wood burning is restricted and discouraged, and many homeowners lean on gas instead — which is why gas units that sat unused all summer get found out in the smoke season, not winter. We service both, so whichever fuel you rely on is ready.
Wood heat is serious heat
In mountain and foothill homes, a wood stove or fireplace is often a primary heat source, not an occasional pleasure fire. That means longer burns, more ash, faster wear on gaskets, baffles and catalysts, and no patience for a unit that underperforms. In Boulder County we service wood units like the heaters they are.
Dry air, dusty pilots
Mountain air is dry, and dry air carries dust into everything — pilot orifices, burner ports and air shutters included. A gas fireplace in Lyons can fail from a dusty pilot alone, with every major part still sound. A thorough cleaning and an altitude check fix most of those calls without replacing a single part.

My gas fireplace won't stay lit at this elevation — is it broken?+
Often it is not a broken part at all — it is altitude. Thin air weakens the pilot flame, so the thermocouple cools, thinks the flame is out, and shuts the gas off. Dust in the pilot makes it worse. A tech cleans the pilot, tests the thermocouple, and checks the altitude setup before replacing anything.
Does a gas fireplace need special setup for high elevation?+
Yes. Gas appliances are rated and adjusted for an elevation range, and a unit set up for low elevation will burn dirty, soot the glass, and struggle to keep a pilot at Lyons elevation. The gas and air setup has to match the altitude it will actually run at — we check and adjust that as part of any installation or repair.
Our cabin sat empty for months — can we just light the fireplace when we arrive?+
Please have it checked first. Months sitting empty in Colorado mountain country means animals may have nested in the flue, dust has settled in the pilot, and caps may have taken snow damage — all invisible from the room. An inspection and cleaning before the first fire is the difference between a cozy arrival and a cabin full of smoke.
Can I burn wood on wildfire smoke days?+
Follow the local air-quality guidance for that day — on bad smoke days, wood burning is restricted or strongly discouraged across much of Colorado, and adding fireplace smoke to wildfire smoke helps nobody. Many Lyons homeowners switch to gas on those days instead. If your gas unit has sat idle, have it serviced before you need to rely on it.
Why does my gas fireplace glass soot up so fast here?+
At altitude, a gas flame that is not adjusted for elevation burns cooler and dirtier, and soot on the glass is often the first visible sign. Dusty burners and shifted logs make it worse. Cleaning the glass alone treats the symptom — a tech cleans the burner, checks the log placement, and verifies the altitude setup so it stays clean longer.
Do you give prices over the phone?+
No — and be wary of anyone who does. Every fireplace fails differently, so a phone price is a guess that changes at your door. Our estimates are free: a tech looks at the actual problem, then gives you one clear price before any work starts.
