Gas fireplace insert installation on the Eastside.
Sound Fire Solutions handles gas fireplace insert installation from start to finish: measuring your firebox, choosing the insert, running a new aluminum flex liner, bringing in the gas line, and finishing the surround. An insert turns a drafty wood burning fireplace into a sealed, efficient gas heater that lights with a switch or remote.

Real heat from the fireplace you already have.
An open wood fireplace sends most of its heat up the chimney, and it pulls warm air out of the room even when it is not in use. A direct vent gas insert slides into the existing firebox and seals it behind glass. It draws combustion air from outside through the chimney, so your room air stays in the room, and it puts real heat into the house at the push of a button.
- Sealed glass front, so no more drafts through the old damper
- Fits the existing masonry firebox with no new framing
- Runs from a remote control
- Optional blower to push heat into the room
Sized to your firebox and your room.
We measure the firebox opening, depth, and the taper of the back and sides before we recommend anything, because an insert has to physically fit and still leave room for the liner connections. Then we match the heat output to the room. A small den and an open great room need very different ratings, and an oversized insert just cycles on and off.
- Firebox measured and chimney inspected on the first visit
- Heat output matched to the size of the room
- Traditional, clean-face, and modern styles
- Surrounds, faceplates, and log or glass media
A new liner inside the old chimney.
A gas insert cannot vent through a bare masonry flue. We run an aluminum flex liner system from the insert to the top of the chimney, either two flexible liners (one for exhaust, one for fresh air) or a co-linear kit, depending on the insert and the size of the flue. Then we cap and seal the top so the chimney stays weather tight.
- Co-linear or two-liner systems, per the insert manual
- Chimney checked for cracks, blockages, and clearance
- New chimney cap and top seal
- Old damper removed or secured as the manual requires
Gas line, permit, and startup.
Most wood fireplaces never had gas, so we run a new gas line from the meter or the nearest branch, sized for the insert and anything else on that line. The gas line and the insert are permitted and inspected, and we carry the permit through to final sign-off. At startup we test the flame and the draft, set up your remote, and show you how to run it.
- New gas line sized, permitted, and pressure tested
- Remote control set up
- Startup, burn test, and a walkthrough of the controls
