A Recent Install, Start to Finish
A real job from our crew — an aging burner swapped for a new vented gas log set. Every install follows the same process: inspect, strip, connect, test, finish.
Step 1 — Before
The old burner — soot, corrosion, unreliable ignition. Common in homes from the '80s and '90s.
Step 2 — Strip & Prep
Old components out, firebox cleaned and inspected, gas stub and shutoff valve checked. Floors stay covered.
Step 3 — Connect & Test
New burner connected, leak-tested, and test fired before the logs go on.
Step 4 — Finished
Logs set to manufacturer spec, ember bed and lava rock placed, final flame check. One visit.
Vented vs. Ventless Gas Logs
We install both. The right choice depends on your fireplace, your jurisdiction, and whether you want looks or heat.
Vented Gas Logs
Damper open, working chimney — combustion gases exit up the flue. Tallest, most realistic flame; the default for masonry fireplaces. Some heat goes up the chimney, so they're ambiance-first. The photos above are a vented set.
Ventless / Vent-Free Gas Logs
Damper closed — nearly all the heat stays in the room. Trade-offs: a smaller, bluer flame, and combustion byproducts (including water vapor) stay in your living space — worth weighing in our damp Puget Sound climate. Not approved in every WA jurisdiction; we confirm what's allowed at your address.
Safety Note on Ventless Gas Logs
Ventless logs include an oxygen depletion sensor (ODS) that shuts the unit off if CO rises — a required safety feature. Even so, some WA jurisdictions don't allow ventless sets. We check local code before recommending one.
What Affects Gas Log Installation Cost
Every fireplace is different, so we quote each job individually — estimates are free. What moves the number:
The Log Set Itself
Usually the biggest line item. Expect $2,000–$3,500+ for a quality set from a manufacturer like R.H. Peterson Real Fyre — designer series, premium charred finishes, and electronic ignition sit at the top of that range and beyond. Cheap sets show their age fast.
Ignition Type
Match-lit is simplest and cheapest. Millivolt adds a standing pilot and wall switch or remote. Electronic ignition costs more up front but eliminates the standing pilot.
Gas Line Work
An existing gas stub and shutoff valve in good condition keeps the connection simple. Extending or re-routing a line adds labor and materials — we'll tell you at the estimate.
Firebox Condition & Size
Bigger fireboxes need bigger sets. Cracks, a failed damper, or worn refractory panels get fixed first — a fireplace inspection catches these before install day.
Total cost depends on the set and what your fireplace needs. Get a free estimate — firm number, no surprises.
Gas Log Repair & Replacement
Already have gas logs that aren't working right? We handle that too.
Off-Track Log Repair
Logs shifted out of position? We reset them where they belong and secure them so the flame pattern is safe and looks right.
Burner & Valve Repair
Burner won't light? Valve acting up? We diagnose ignition problems, gas flow issues, and worn components — see our valve repair and ignition repair services.
Upgrades & Replacements
Old, worn, or discolored logs drag down the whole fireplace. We swap them for a new set that looks good and burns the way it should.

"I hadn't used our gas fireplace in years, and when I finally wanted to light it, nothing happened. This company's gas fireplace repair service had it up and running in no time. They cleaned the burner, replaced a faulty thermocouple, and now our fireplace is the centerpiece of our living room."
Rebecca Mayorga
★★★★★
"I had a great experience with AAA fireplace services, particularly our technician David. He was clearly extremely knowledgeable and was able to fix our fireplace with spare parts he had already with him. Highly recommend them, it's hard to find reliable and reasonably priced services these days."

Frequently Asked Questions
How much does gas log installation cost?
The log set is the biggest variable — expect $2,000–$3,500+ for a quality set, with designer series, premium charred finishes, and electronic ignition at the top of that range and beyond. Labor depends on ignition type, gas line work, and firebox condition. Every job gets a free estimate with a firm number before work starts.
Can I install gas logs myself?
No — installation involves gas line connections, precise log placement for safe flame distribution, and local code compliance. Done wrong, gas logs can produce carbon monoxide or create a fire hazard. Have a licensed technician do it.
What’s the difference between vented and ventless gas logs?
Vented logs need an open damper and a working chimney — gases go up the flue, and you get the most realistic flame. Ventless logs run damper-closed and keep more heat in the room, but combustion byproducts stay in your living space, and they're not approved everywhere. We'll tell you what's allowed at your address.
My gas logs won’t light — is that repairable?
Usually, yes. Most ignition failures come down to a faulty valve, worn igniter, weak thermocouple, or gas flow problem — all fixable. We carry common ignition parts on the truck, so many repairs get done same-day.
How long does gas log installation take?
Most installs take one visit — typically two to three hours, faster if the fireplace already has a gas connection. The job in the photos above took one visit. You'll get a realistic timeline with your estimate.
Do I need to buy my own gas log set, or do you supply them?
Either works. If you've already picked a set, we verify it fits your firebox before installing — not all sets work in all fireboxes. If you haven't, we'll help you choose the right type and size. Getting selection right before you buy saves trouble.
Can I add gas logs to any fireplace?
Most wood-burning fireplaces can take gas logs if the firebox meets minimum dimensions and is structurally sound. We check during the estimate — cracks, deteriorated mortar, or a damaged damper get fixed first. We won't install into a compromised firebox.
