Lake Living and Wet Ground
Pewaukee, both the city and the village, wraps around Pewaukee Lake, with older lake homes, newer subdivisions and everything in between. Homes close to the lake and the Pewaukee River often deal with groundwater that sits close to the basement floor.
Newer homes have poured walls and sump systems that work hard every spring, while older lake homes may sit on foundations that were never meant to keep a finished basement dry. Clay soil holds water against the walls throughout the region.
We'll trace where water is getting in and recommend the right fix, whether that's a better sump system, new drain tile or sealing a single crack.

How We Help Pewaukee Homeowners
Sump PumpsSump Pumps & Battery Backups
Near the lake, a dependable sump system is your first line of defense. We install properly sized pumps with battery backups.
For very wet lots, a second pump adds capacity.
We test the system before we leave and walk you through how it works, so you know your Pewaukee basement is protected the next time a storm rolls through.

SeepageFloor & Wall Seepage
Seepage at the floor edge means pressure under the slab. Interior drain tile relieves it and carries water to the sump.
Only a narrow strip along the walls is opened and patched.
Because the fix relieves the pressure instead of just sealing the surface, the water doesn't simply move to a new spot. Most Pewaukee homeowners notice the difference after the very next storm.

WaterproofingInterior Drain Tile & Sump Systems
Older lake homes often have little or no drain tile. New interior drain tile can make a dramatic difference.
It's installed from inside, so your yard stays untouched.
When the work is done, the trench is patched with fresh concrete and the basement is cleaned up, so you can get back to using the space. It's one of the most dependable ways to keep a Pewaukee basement dry year after year.
