Plumbing Services in Superior, WI & Duluth, MN
Six plumbers on staff, one phone call.
Leaks, drains, water heaters, sewer lines, septic. Since teaming up with Botten Plumbing in 2021 we do the whole house, not just the furnace next to it.
We bought the plumbing shop, not a phone number.
In 2021 Advantage Air joined forces with Botten Plumbing, a respected local shop. Six plumbers on staff came with it, along with full septic capability. That is why one company can handle your furnace and the water heater standing next to it.
- Six plumbers on staff, so you get a pro this week

What homeowners ask us
Six plumbers on staff. That came from joining forces with Botten Plumbing in 2021, and it is the reason we can usually get you a pro this week instead of next month.
Yes. Plenty of homes out past the city lines run septic or holding tanks, and most HVAC shops will not touch them. We service and pump both, and we handle the plumbing side that connects to them.
Shut off the main and call us. Frozen and burst lines are a real winter category here, not a rare event, so we answer 24/7 for them. Do not thaw a line with an open flame.
Yes. One call, one company, one invoice, whether it is a water heater, a drain, or the furnace next to it.
One call covers the whole house.
Leak, drain, water heater, or septic. Talk to a real person from the Twin Ports.
