Serving Thiensville Since 1981

A River Village With Every Kind of Foundation

Thiensville is a small village with a long history. Homes near its old downtown and along the Milwaukee River include some of the oldest in the area, many with stone or brick foundations, while surrounding neighborhoods were built in the decades after World War II.

Being close to the river means groundwater can rise quickly after heavy rain and spring thaw. Older stone foundations let water seep through softened mortar, and mid-century homes often have drain tile that's past its prime.

No matter how old your home is, we'll find what's causing the problem and give you a straight answer and a written estimate.

How We Help Thiensville Homeowners

Water running down a basement wallWall Leaks

Leaking Walls

Older Thiensville stone foundations usually need drainage plus repointing the worst mortar joints.

Poured walls in newer homes 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 Thiensville project.

Interior Drain Tile & Sump Systems

New interior drain tile and a sump give river-area groundwater a dependable way out.

It works in both historic and mid-century basements.

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 Thiensville basement dry year after year.

Sump Pumps & Battery Backups

Homes near the river need pumps that can keep up. We install properly sized pumps with battery backups.

We route the discharge well away from your foundation.

We test the system before we leave and walk you through how it works, so you know your Thiensville basement is protected the next time a storm rolls through.

Bowing Wall Bracing

Older block and stone walls can bulge or lean after decades of pressure. We stabilize them with bracing and repair.

We measure first, so you know exactly what the wall needs.

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 Thiensville home measured sooner rather than later.
