OUR GOAL is to create lasting relationships by providing our customers with effective solutions, reliable service, plus a personally and professionally rewarding experience. 

Everyone on Zien's team has a sincere concern for your needs. Zien's project managers maintain a high level of knowledge and a commitment to approach each situation with a positive attitude. We strive to make our customers feel comfortable in knowing they can depend on us to meet any of their special needs.

 

It's old-fashioned, but we still do what we say we're going to do. We keep our promises.

We work hard to understand exactly
what you want.

 

We work twice as hard to make sure nothing is lost in the translation. 

 

Our word is our bond, and that applies to our deadlines, as well.

 

We are always ready to go that extra mile for you.

In the year 1919...

ZIEN PLUMBING held a 900 sq. ft. storefront in Shorewood, Wisconsin. Our size has changed but our core values remain the same

We're now headquartered in a 40,000 sq. ft. facility in Glendale, Wisconsin and proud to say our family-owned and operated company has grown into one of Milwaukee's biggest and most reliable mechanical contractors.

 

OUR MISSION is to provide the highest quality services at competitive prices while maintaining an unparalleled level of integrity.

INTEGRITY: DOING THE RIGHT THING EVEN WHEN NO ON IS WATCHING.

OUR CONCERN DRIVES US INTO ACTION.

ABILITY WITHOUT HONOR IS USELESS.
