L&L Builders would like to personally thank Interstate Mechanical Corp for their many positive contributions and total commitment on the now complete VA Outpatient Clinic in Dakota Dunes, SD. As a very thoughtful subcontractor, we couldn't have asked for more as they were both strong in the field and in the office. We greatly appreciated the team's engagement, planning, flexibility and proactive responses to project changes. Interstate Mechanical was an exceptional partner on this project, and their actions surrounding safety, quality and timely completion of work was second to none.
