Fireplace Inserts in Arleta, Sized From the Inspection

Think of an insert as a sealed stove built to sit inside the masonry opening you already have, with its exhaust carried up a fresh liner to the top of the stack. It turns an open fireplace, which sends most of its heat up the flue, into a heater that warms the room. The fit is everything. We measure the firebox opening at the front and back, the depth, and the height, and note the hearth depth in front, since many inserts sit partly on the hearth. Those numbers go into the report along with photos, and they narrow the list of inserts that can physically go in.

The chimney matters just as much. A gas insert needs a liner from the insert to the top of the chimney, and a wood insert needs a full stainless liner sized to the appliance. We inspect the flue before quoting to check it can take a liner: no major offsets, no collapsed tiles, a crown that can be sealed around the new pipe. For a factory-built fireplace, we check whether the manufacturer allows an insert at all, since many do not. The report spells this out before you spend time choosing a model.

With us, a gas insert in an existing fireplace comes to $2,700 to $5,400 installed, which includes the unit, the liner and the connection. Where in that range a job lands depends on the insert's size and features, the chimney height, and how far the gas line has to run. Wood and electric inserts are quoted in writing for the model you choose. Changing what burns in a fireplace calls for a Level 2 inspection under NFPA 211, and we include the flue camera check in the insert job so you are not paying for two visits.

On install day we photograph the liner going in, the connection at the top, the crown seal around the pipe, and the insert in place with its clearances to the mantel and trim. Those photos, the model and serial number, and the permit sign-off where one is required go into a completion report. Keep it with the insert manual. Anyone servicing the unit later will want the model number, and any buyer's inspector will want to know the liner was installed and how.
