Damper Repair
Fixing stuck, rusted or drafty dampers so you can open the flue to burn and close it to save energy.

The damper is the valve that opens the flue for a fire and closes it to keep heated or cooled air from escaping. When it rusts, warps or won't seal, you're either stuck with a flue that won't open or a chimney that leaks your energy bill up the stack. We repair and adjust dampers so they work — and seal — the way they should.
