Gas Fireplace Inserts for Mercer Island Homes
Keep the character. Upgrade the comfort.
An existing masonry fireplace can be a beautiful centerpiece in an older Mercer Island home—but hauling wood, cleaning ashes, and losing heat up the chimney can make it something you rarely use.
At Thompson’s Hearth & Home, we help homeowners turn existing wood-burning fireplaces into convenient sources of warmth with professionally installed gas inserts. You can often keep the brick, stone, or masonry that gives your fireplace its character while upgrading what’s inside.
A New Fire Inside Your Existing Fireplace
A gas insert is a heating appliance designed to fit inside a suitable existing fireplace. It brings the flame behind a sealed glass front, with venting liners routed through the chimney.
For many homes, this means you can update the fireplace without a complete tear-out of the surrounding masonry. The finished result combines the familiar look of your home with the convenience of a fire you can enjoy at the touch of a button.
Is Your Masonry Fireplace a Good Candidate?
If you have an existing wood-burning masonry fireplace, a gas insert may be a great option. Before recommending a model, we review:
The fireplace opening and interior dimensions.
The chimney’s configuration and condition.
Clearances to the mantel and surrounding trim.
Access to a gas supply and electrical power.
Older fireplaces vary considerably in size and construction. We help you understand what will fit, what preparation may be needed, and which options best suit your room.
Comfort Without the Woodpile
A gas insert makes it easy to enjoy your fireplace more often. There’s no wood to carry, no ashes to shovel, and no waiting for a wood fire to get going.
Our gas inserts offer adjustable flames, thermostat control, and ceramic glass designed for high-temperature fireplace use. We’ll help you compare flame appearance, heating capacity, and finishing options so the insert feels right for your home.
