“Trefz Mechanical worked with us as the plumbing contractor on an elementary school project, installing a 120-gallon, high- efficiency hot water heater as well as renovating two main bathrooms. Our window was short since these kinds of projects must be completed in the summer when the students are not in session. Working directly with the owner, they addressed questions/issues to close out the project in a timely fashion.”
