A Modern Gas Unit in Your Existing Fireplace
A gas insert is a sealed, high-efficiency gas unit that slides into your existing masonry fireplace opening. Most homeowners go this route when their old wood-burning fireplace looks tired, throws no heat (open masonry fireplaces actually lose heat from your home), and they're tired of dealing with kindling, ashes, and chimney sweeps.
A good gas insert install transforms the room and the energy bill. The unit fits in the existing opening, vents through a stainless liner up the existing chimney, and produces 75–85% efficiency vs. roughly 10% for the open fireplace it replaced. The savings on heating costs are real.
We carry top-tier gas inserts from Lopi, Heat & Glo, Fireplace X, and Mendota—and we install them turnkey, including the gas line, the chimney liner, the surround/mantle changes if you want them, and the finish work.
Why Insert Vs. New Fireplace?
Lower Install Cost
Use the existing opening—no framing, no new venting through walls.
Massive Efficiency Jump
75–85% vs. ~10% for an open masonry fireplace. Real heat, real savings.
Same Room, Better Look
Modern flame patterns and surrounds that update the whole space.
Faster Install
Most gas insert installs finish in a single day.
