Fireplace Installation

Fireplace Installation in the Seattle Area, WA.

Putting a fireplace into a house that never had one is framing, venting, clearances and masonry in the right order. One crew, one scope, one warranty.

Everything Behind the Opening

The Fireplace Is the Last Thing That Gets Built.

A new fireplace looks like a single purchase and is actually a sequence. Before the unit arrives, something has to carry it, something has to vent it, and the wall and floor around it have to be built to hold a heat source at the clearances the manufacturer specifies. Get that order wrong and you discover it at the end, when the chase is closed and the hearth is tiled.

The decisions worth making early are the ones that constrain everything after them. Where it vents – straight out through the wall behind it, or up through the roof – decides where in the room it can go. Whether it is a built-in unit framed into the wall or a freestanding appliance decides the hearth. The fuel decides the venting: a sealed direct-vent gas unit can go on an exterior wall with a short run, a wood-burning unit needs a proper vertical flue with the height and clearances to draw. And a masonry face is weight, which means the floor under it and the wall behind it have to be built for it rather than asked to cope.

We install fireplaces as one job from the structure outwards: framing and support, the vent run, the unit set to its listed clearances, then the hearth, the surround and the mantel. The alternative – a fireplace dealer, a carpenter, a gas fitter and a mason, each arriving after the last one left – is where the coordination problems and the “that is not my part” conversations come from.

How We Work

How We Install a Fireplace

Venting and structure first. The part you look at is the last thing that happens.

Full system inspection

We look at where you want it and what that location allows: the wall behind it, the floor under it, the route a vent can take, and what is in the way in the framing above.

01

Define the Scope

You get the unit, the vent route, the framing and support, the clearances it has to hold and the finish materials set out in one written scope, with any permit identified.

02

Execute the Repair

Framing and support built, the vent run installed and flashed where it leaves the building, the unit set to its listed clearances, then hearth, surround and mantel.

03

Verify & Document

We confirm the unit is at its listed clearances and the vent terminates correctly, operate it, and hand over photographs of the framing and venting before they were closed in.

Why Chimneyz

One Company, One Installation

A fireplace crosses four trades, and on most jobs those four invoice separately and point at each other when something does not line up. We carry the structural, venting and masonry work ourselves, so the clearances are our problem, the flashing where the vent leaves the building is our problem, and the surround is built by the same people who framed what it sits on.

FAQ

Fireplace Installation FAQ

Most installation problems are decided before anything is bought. These are those decisions.

Can a fireplace go on any wall?

Not quite. The venting decides it. A sealed direct-vent gas unit can usually go on an exterior wall with a short horizontal run; anything that needs a vertical flue needs a clear route up through the house.

How long does an installation take?

The unit and venting are usually a few days. What lengthens it is the finish – a full masonry surround and hearth takes longer than a tiled face, and curing time is real time.

Do I need a permit?

Usually yes for the venting and any gas work, and requirements differ across Puget Sound jurisdictions. We identify what applies during the assessment rather than after the work starts.

What is a hearth extension and do I need one?

The non-combustible floor area in front of the opening. Its required size comes from the unit’s listing, not from taste, and it is one of the things most often built too small on a remodel.

Can you build the surround as well as install the unit?

Yes, and that is the point of doing it as one job. The surround is masonry, which is our core trade, and it has to be built to the clearances the unit requires.
