In 1919, Zien Plumbing held a 900 sq. ft. storefront in Shorewood, WI.
Now, headquartered in our 26,000 sq. ft. facility in Glendale, WI, we’re proud to say our family owned and operated company has grown into one of Milwaukee's biggest and most reliable mechanical contractors. It's old-fashioned, but we still do what we say we're going to do. No shortcuts.
Our mission is simple: To create lasting relationships by providing effective solutions and reliable service.
We work hard to understand 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.
Since 1919, Zien Service, Inc. has served commercial, industrial and institutional customers throughout Wisconsin and Northern Illinois. A single-source contractor, we specialize in the design, fabrication, installation, maintenance and service of HVAC, plumbing, refrigeration and automation systems and more.
