Our Story

80 Years of Family Foundation Experience

American Foundation Specialists has been fixing foundations in Southeastern Wisconsin since 1947. In all that time, one thing hasn't changed: it's a family business, and the family's name is on every job.

Today the company is led by Tony Zidar, Jr. and his son Jayme Zidar, who started working in the business at 16 and learned the trade from the ground up, in basements, trenches and job sites across Milwaukee, Waukesha, Racine and Kenosha counties. That kind of hands-on experience is something you can't hire or buy. It's built one foundation at a time.

We've seen how Wisconsin's clay soil, freeze-thaw winters and aging drainage affect homes of every age, from century-old stone foundations to basements poured last decade. That experience is what lets us look at a crack or a wet wall and tell you plainly what's causing it and what it will take to fix it.

How We Work

Doing Things The American Way

Honest Diagnosis

We tell you what's really going on, even when that means telling you that you don't need us. Sometimes the right answer is a downspout extension, not a foundation repair.

Fair, Written Estimates

Every inspection ends with a clear explanation and a written estimate, so you know exactly what's being recommended and why, with no pressure to decide on the spot.

Done Right the First Time

We fix the cause, not just the symptom. A crack sealed over a moving wall just comes back, so we make sure the repair actually solves the problem.

Local & Family Owned

We live and work here. Our office is in Hales Corners, our crews know Wisconsin soil, and our name has been on this work for 80 years.
