Serving West Allis Since 1981
Classic City Homes on Tight Lots
West Allis is full of bungalows, Cape Cods and duplexes built from the 1910s through the 1950s, set close together on city lots. The same goes for neighboring West Milwaukee. Many of those homes have block foundations that have been cracking and seeping for years.
Tight lots and shared driveways make exterior digging difficult, so interior repairs are usually the best fit here. Older drain tile, shallow sump pits and window wells without drains are common sources of trouble.
We'll find what's causing your problem and give you a clear, written estimate, whether you own a single-family home or a duplex with tenants.

How We Help West Allis Homeowners
WaterproofingInterior Drain Tile & Sump Systems
Interior drain tile and a sump are often the best fit on tight West Allis lots, since everything is done from inside.
It relieves pressure along the walls and floor so seepage stops.
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 West Allis basement dry year after year.
Drain Tile Details
Bowing WallsBowing Wall Bracing
Horizontal cracks and leaning block walls are stabilized with steel braces installed from inside.
No digging in your yard or your neighbor's.
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 West Allis home measured sooner rather than later.
