Liners
The liner is what actually carries smoke and combustion gases safely up and out. A cracked, undersized or missing liner is a safety issue, and it's usually invisible until a camera goes down the flue.
Liner installation covers fitting a properly sized stainless steel liner for the appliance or fireplace it serves, replacing a liner that's cracked or deteriorated, and relining older chimneys that were never properly fitted with one in the first place.
Liners deteriorate from age, heat cycling, and chimney fires or near-fires that stress the material beyond normal wear. Many older homes were built before liners were standard, or were relined informally over the decades for systems that no longer exist.
We size the liner to the specific appliance or fireplace — undersized or oversized liners both cause draft problems — and install it the full length of the flue, sealing connections properly at each end. A camera check afterward confirms a clean, continuous liner with no gaps.
Older housing stock in any climate is more likely to need a liner check, but it's especially common in markets with a lot of pre-war construction, where chimneys were frequently built for heating systems that have long since been replaced.
