Serving Wauwatosa Since 1981
Classic Tosa Homes, Century-Old Foundations
Much of Wauwatosa was built between the 1910s and the 1950s, from bungalows in east Tosa to the period homes of Washington Highlands and the post-war neighborhoods farther west. Many of those homes sit on block, brick or stone foundations that have been holding back wet clay for generations.
The Menomonee River and Underwood Creek run through the city, and homes in lower areas near them can see groundwater rise quickly in heavy rain. Add aging drain tile and finished basements, and it's easy to see why Tosa homeowners call us.
We'll find what's causing your water or wall problem, explain it plainly and give you a written estimate for the fix.

How We Help Wauwatosa Homeowners
Wall LeaksLeaking Walls
Older Tosa foundations often leak across whole sections. We combine drainage with repointing to keep them dry.
Poured walls get crack injection from inside.
We'll show you exactly where the water is getting through and explain why we're recommending one repair over another, so there are no surprises on your Wauwatosa project.
Wall Leak Repair
Bowing WallsBowing Wall Bracing
When older walls start to lean, steel braces stop them from inside with no digging in your yard.
We measure each wall so the repair matches the movement.
Caught early, a moving wall is a straightforward fix. Waiting usually means a bigger repair, which is why we recommend having any leaning wall in your Wauwatosa home measured sooner rather than later.

WaterproofingInterior Drain Tile & Sump Systems
New interior drain tile and a sump give groundwater a dependable way out, especially near the river and creek.
It's installed from inside and patched with fresh concrete.
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 Wauwatosa basement dry year after year.

ExteriorExterior Waterproofing
For finished basements you'd rather not open up, exterior waterproofing keeps water off the wall entirely.
We excavate, seal and add drainage, then restore the yard.
It's a bigger project than interior work, but for the right Wauwatosa home it's the most complete protection you can get.
