Pewaukee is really two communities. The Village of Pewaukee, incorporated in 1876, wraps around the east end of Pewaukee Lake and holds much of the area’s older housing. The City of Pewaukee formed in 1999 from the surrounding township and consists mostly of subdivisions, many built in the last few decades. Southport serves homeowners in both areas, with heating, cooling, plumbing, and water treatment handled from our Caledonia location.

Heating & Cooling
Older homes near the lake and in the village tend to have systems that were added or replaced piecemeal, sometimes with ductwork that was never sized for the current layout. Newer homes in the city are usually tighter and better insulated, but large open floor plans and finished basements can still leave some spaces uncomfortable. Both deal with the same long Waukesha County winters and humid lake summers.
- A home that heats unevenly, or a furnace that runs constantly on cold nights, is worth having diagnosed before it fails.
- Village homes with radiators can keep that steady heat with boiler service and upgrades.
- Central air that struggles through humid stretches near the lake often needs air conditioning repair or a closer look at sizing.
- If one room never matches the rest, a ductless mini split can heat and cool it without new ductwork.
- Dust, dry winter air and allergies are often improved with indoor air quality equipment such as filtration and humidifiers.
Book heating or cooling service before the next temperature swing puts your system to the test.
Plumbing, Water Heaters & Water Treatment
Pewaukee’s municipal water comes from groundwater wells, and some of those wells tap deep sandstone that carries naturally occurring radium. The village has been adding radium treatment at affected wells to meet state limits. That deep groundwater is also hard, so scale builds quickly in water heaters and fixtures. Homes around the lake that sit outside utility service areas may be on private wells with their own water quality concerns.
- Scale, spotting and dry skin are common reasons homeowners add water treatment such as softening or filtration.
- A water heater that pops, rumbles or runs out of hot water early is often loaded with mineral sediment.
- Slow or backed-up drains in older village homes often need professional drain cleaning to clear buildup and roots.
- Leaks, running toilets and fixture swaps are covered under our plumbing services.
