About us

Since 1922, Maas Brothers Construction has built a reputation for providing quality commercial, industrial and institutional construction services. 

As one of Wisconsin’s oldest general contracting firms, Maas Brothers handles building projects in our hometown of Watertown, Wisconsin, as well as Milwaukee, Madison, and surrounding areas. We’ve served as general contractor for many long-term clients, including relationships dating back more than 60 years. Construction partnerships like that don’t just happen; we’ve earned the respect and trust of our clients through hard work, dedication, and support of local businesses.

The people who work for Maas Brothers live and work in the communities we serve, so we have an extra reason to give our clients a smooth construction process and finished buildings to be proud of.
