What We Are About

Since our inception in 2005, Wein & Shearer Mechanical has been driven to become one of the Midwest's premier mechanical contractors. At WSM, there is no project too big or too small. Our entire team at WSM is committed to being "hands on" in the completion of any project our customer has entrusted to us. Customer service satisfaction is a number one priority to both owners' Greg Wein and Rick Shearer, who has a combined forty years of hands on experience as certified tradesman.
