What Karlsen Plumbing covers, division by division
One office, one Wisconsin licence, six divisions. The same company that runs the service trucks also roughs in around 200 new homes a year, remodels kitchens and bathrooms, and handles multi-family, commercial and industrial piping across Southeast Wisconsin. Below is the full range, and the detailed service list underneath it.

Service trucks
Service and repair
Water heaters, sump pumps, backflow testing, burst and frozen lines, and the drains a plunger will not move. OEM repair parts on the truck, jetters and cameras in the shop.

Remodel division
Remodel plumbing
From a fixture swap to a bathroom or kitchen that moves to a different wall. Home additions and light commercial included.
