Can a gas insert be installed in my existing masonry fireplace?
Yes — and in Flat Rock, where homes date to the 1800s with oversized open masonry fireplaces and aging clay flue liners, a gas insert is often the upgrade that preserves the character while fixing the draft. It seats inside the historic firebox, vents through a new stainless liner, and ties into natural gas. The room stops losing heat up an old chimney it was never sealing.
Old bones, honest condition
Those big early fireplaces are beautiful and terrible at holding heat — an open masonry firebox this size pulls a steady draft of warmed room air up the chimney, and on a cold Flat Rock night it can run a net heat loss. The clay flue liners in these houses are often decades past their prime. That's actually why the insert works so well here: we confirm the flue, then run a fresh stainless liner top to bottom for the sealed unit, and the old damper is clamped or removed so it can't close on it. The mantel and surround you love stay exactly as they are.
Sealed heat that respects the house
A gas insert commonly runs 70% efficient or better and lights on a switch — no cold-start smoke drifting into a 150-year-old parlor. Around Kanuga and Highland Lake, that draftiness is the number-one complaint about these historic hearths, and sealing the firebox is the fix. Connecting the gas is licensed work in North Carolina, so we run and pressure-test the line, pull the Henderson County permit, and meet the inspector — one company accountable for the whole retrofit rather than a showroom pointing you elsewhere to find someone licensed to connect it.
