Mielke Mechanical

The MIELKE family started in the mechanical contracting business in the 1940’s in Northeastern Ohio. Since that time we have grown into a national contractor specializing in piping and related mechanical systems. Large scale plumbing, heavy HVAC, process & utility piping and fabrication & modularization are what we excel at.  

MIELKE Mechanical is a full service mechanical contractor serving the Industrial, Institutional, Heavy Commercial and large Multi-unit Residential markets across the country. We provide plumbing, HVAC, process & utility piping services. We strive to utilize the best technologies available and to be a cutting edge in our management approach and our operational delivery. We utilize automated on-screen take-offs for estimating and we model our projects using BIM 3-D design and clash detection software. We run multiple full-time fabrication facilities striving to pre-fabricate and pre-assemble as much of our work as possible. We have multiple permanent offices and have completed projects in 25+ states and the US Virgin Islands. From Wyoming to Massachusetts and South to St. Croix, we have tackled large & complex projects in some very challenging locations! We are a relationship based contractor and these strong partnerships with our clients are what drives our geographic diversity. We take a long-term approach to our client relationships and you won’t find another contractor more committed to exceeding our clients’ expectations than MIELKE.
