How much does a chimney liner cost when installing a gas or wood insert?
Flat Rock's historic 1800s homes make the liner especially relevant — many still have their original oversized open masonry fireplaces venting through aging clay flue liners that are cracking with age. A stainless liner sized to a new sealed insert bypasses that failing clay entirely, and it's the fix that tames the cold-air draft without touching the character of the fireplace.
Old clay liners, and why stainless replaces them
Flat Rock has some of the oldest housing we serve — grand homes dating to the 1800s around Historic Flat Rock, Kanuga, and Highland Lake, built with big open hearths and clay-tile flues. Clay liners crack and shift over a century-plus of heat cycling and settling, and a cracked flue tile twenty feet up is both a draft problem and a safety one. When you add a sealed insert, its exhaust travels inside a new full-height stainless liner rather than the old clay — so the aging tiles stop mattering, and you get a flue the appliance was actually designed for.
Sealing the draft without losing the character
The other Flat Rock complaint is cold air — those beautiful old open fireboxes act like an open window, pulling chilly air down the flue and into the room. A sealed insert with a properly sized liner closes that loop: the draft reverses, the heat stays in the room, and the historic mantel and surround stay exactly as they are. It's one of the most satisfying upgrades in these older homes — real, controllable heat behind a fireplace that still looks its age in the best way.
