Why a Gas Insert
Seal the Draft, Keep the Fireplace, Add the Heat
If you have an open masonry fireplace, you have a hole in the house. A gas insert slides into that opening, seals it with a glass front, and runs two liners up the existing chimney—one in, one out. What you get back is a fireplace that heats the room with the flip of a switch and keeps going when the power is out.
The Heat & Glo inserts we install come in traditional log-set and clean-face styles, with surrounds sized to cover the opening so the result looks built in. The project is usually a single day. We coordinate the gas line, run the liner, fit the surround, and light it before we leave.
Get an instant installed estimate on the insert you like, then we'll measure the firebox and the flue at a free in-home visit and confirm the number on the spot.
What You Get
Why Customers Choose Gas Inserts
Ignition That Works Without Power
Standing-pilot and battery-backed ignition keep the fire lit through an outage.
Heat, Not a Draft
An open fireplace pulls warm air out of the house; a sealed insert keeps it in and adds its own.
Installation in a Day
Liners up the existing chimney, surround over the opening, fire lit—usually before dinner.
Surrounds Sized to Your Firebox
Surrounds and fronts sized to your firebox, in finishes that match the room.
