Safe, Code-Compliant Venting for Your Gas Appliances
Older masonry chimneys were often built for wood-burning fireplaces, not modern gas furnaces, boilers, and water heaters. When these appliances vent into an oversized or deteriorating flue, it can lead to poor draft, condensation damage, and unsafe combustion gas buildup. SE Wisconsin Chimneys relines and converts chimneys so your gas appliances vent safely and meet current code.

Under Your Chimney: How It Works
Relining Reimagined
A cracked, oversized, or deteriorating flue is a safety issue, not just a maintenance one. We install a properly sized stainless steel liner from the top of your chimney down to your appliance connection, giving your furnace, boiler, or water heater a safe, leak-free path to vent.
B-Vent Conversion
When a masonry chimney can no longer safely vent a gas appliance on its own, we convert it to a B-vent system — a double-wall metal vent that connects your appliance to a proper termination at the roofline, opening the door to higher-efficiency equipment.
Keep your furnace and water heater in prime condition.
