Grunau Reviews & Testimonials

We saw how nicely aligned the transition from copper to pex was oriented...this work was done by Grunau Company; a great example of people who care about their work! This is standard for our team but it sure makes your Friday when you get to see the systems done properly, particularly when no one will ever see them again. Craft is alive and well!

- Matt Lutz, Founder at Flatwater Homes LLC

All of your employees are very friendly, professional and a pleasure to work with!

- Jim Karls, District Manager at Stericycle

Thanks for working safely, with good housekeeping practices and just being customer focused.

- Don Kostrzewa, Maintenance Manager at Veolia Water N America

The fire protection system at the Flint Hills Resources Milwaukee Terminal offered some unique challenges to Grunau, and they performed exceptionally at every turn. The site restrictions and customer expectations could not have been any higher, and the Grunau personnel rose above the restrictions and led the effort to complete, commission, and train the Owner on a system that they were not familiar with. Performance specifications can often prove difficult with subcontractors that are not familiar with a design-build firm, but Grunau provided excellent services and delivered on their promise. It was a pleasure to have the opportunity to work with the good people at Grunau.

- Eric Kirchhofer, Project Manager at Burns & McDonnell

The accuracy, timeliness and detail of the information you provide is extremely valuable to us, and we owe a large part of our success to you. The abilities and professionalism of your staff gives you tools that very few other organizations have the ability to draw upon.

- Mark Sherry, General Manager at Mortenson

I would like to compliment your guys who are working on the condensate line. They are very professional and continue to go the extra mile without me having to watch over them. Choosing Grunau is proving to be a great choice!!

I cannot tell you how impressed we were with the commitment and service from each and every one of your staff. Due to your outstanding efforts, Milwaukee now has what is clearly a world-class facility.

- Steven G. Chamberlin, President at CG Schmidt, Inc.

- Donald Anderson, Facility Manager at Accutec

My thanks to you and your team on an outstanding effort in repairing the Veolia Water South Shore Interplant Sewer. Grunau performed flawlessly in the safety arena; your team provided lean solutions when required as the project stalled and were professional start to finish. And showing up very quickly when called as the leak was discovered won't be forgotten quickly.

- Don Kostrzewa, Maintenance Manager at Veolia Water North America

I just wanted to take a moment to thank you for the expertise and experience that you have brought to the project. Your ability, and the abilities of your team members, has been instrumental in identifying many conflicts and issues for construction.

- Cindy Finstad, Project Manager at Mortenson

Grunau Company did an outstanding job. How many companies can get a contract award one day and be on site the very next day?

- Andy Blomstrom, Superintendent at JP Cullen & Sons, Inc.

I wanted to take the time to tell you how incredibly impressed I am with your employees. In my 26 years of service, working with several contractors, I have come to the determination that NO ONE compares or offers the above and beyond service that Grunau provides. While working at Metavante I was impressed with Grunau Company and once I took my position with Johnson Controls at Miller Park, it was apparent to me, I needed to bring Grunau on board.

- Luis V. Roche, Operations Supervisor/Miller Park at Johnson Controls, Inc.

I was amazed at the quality of work, cooperation, willingness to work together, and the professionalism of Grunau’s employees.

- David Hale, Project Engineer at HDR Architecture

You should be proud of your staff for their exceptional service!

- Steven G. Chamberlin, Former President at CG Schmidt, Inc.

Grunau Fire Protection should be recognized as part of the reason for the Marquette Interchange project's success. The standpipe system they designed was easy to install and the fabrication work done in Grunau's pipe shop was excellent. The Milwaukee Fire Department is extremely happy with this system.

- Dennis M. Maney, P.E., Marquette Core Project Manager at Edward Kraemer & Sons, Inc.

The experience and skill level of the Grunau team, combined with their concern for customer satisfaction and their respect for our budget, guarantees a job well done every time.

- Richard Nowakowski, Maintenance Supervisor for Housing at Milwaukee School of Engineering (MSOE)

We have been battling some issues over the last few days with our penguin temps, and Randy (your technician) has been here for us to troubleshoot our system. His dependability, patience and overall demeanor when he is here is the best. I know he understands how stressful it is for us when the welfare of our animals is threatened, and his cool head and calm demeanor give us all confidence that any troubles will be resolved quickly and effectively.

- Alex Waier, Bird Curator at Milwaukee County Zoo

I would like to extend a 'huge' thank you to the Grunau team for the effort that took place in fixing the water main break at our corporate headquarters. The team performed admirably and demonstrated your company's dedication to exceeding its customers' expectations. Please pass on my sincere thanks for a job well done.

- Ward Komorowski, Director, Facilities and Building Services at Johnson Controls, Inc.

All of your employees are very friendly, professional and a pleasure to work with!

- Jim Karls, District Manager at Stericycle

Grunau was involved in the construction of many of our buildings and their continued involvement in the day-to-day operations of the facility continues to benefit Miller. The relationship our companies have enjoyed over the years is a testimony to the trust factor we have established and the values we share. The personal involvement by Grunau's management ensures a very high level of customer satisfaction.

- Tom Blaedon, Corporate Facilities Manager at Miller Brewing Company

I wanted to express our thanks to Grunau's team for their help with the problems we are having with one of our surgery HVAC units. They located the parts and stayed late last night and again will this evening. They all really stepped up so we could continue to provide uninterrupted service to our customers. Thank you.

- Mike Connor, Director of Facility Operations at Aurora Health Care

You put forth a superb effort to reach our goal. I would like to thank you for the energy and cooperation in maintaining the overall construction schedule.

- Bruce F. Danek, Project Manager at CG Schmidt, Inc.

Your field forces were some of the most competent individuals I’ve ever seen. [They] went way beyond the normal effort required to make a complex mechanical project successful.

- Gene Hult, General Superintendent at Gilbane

When I take a look at this project after the fact, just from a safety, performance and value standpoint, Grunau did an excellent job. They exceeded my expectations. We had three contracts on this job and two of those contracts ended up costing less than what we originally expected. Grunau's people do a great job. Our whole team is looking forward to working with them again.

- Mark Lillesand, Senior Project Manager at CG Schmidt, Inc.

Grunau Mechanical proved once again to be among the best and has been chosen as one of our top area subcontractors!

- Steven G. Chamberlin, Former President at CG Schmidt, Inc.

I wanted to express my appreciation for the flexibility that your crew showed during the equipment removal and placement for our Compound Management Services project at Sigma-Aldrich. Due to roof access constraints, the crew quickly shifted priorities and removed the exhaust fan before placing the make-up air unit, which was the reverse of their original plan. Your guys were well prepared, accommodating, and did a professional job and they should be commended as such.

- Gary Kok, Project Engineer at Sigma-Aldrich

Grunau is showing their leadership in and commitment to LEED by putting forward their own resources to dedicate the space they work in on a daily basis to LEED certification.

- John Gilroy, Project Executive at Gilbane
