Our Work Speaks for Itself

I worked with McClure Company at West Shore School District and Elizabethtown Area School District. Both with great success! West Shore was building wide mechanical upgrades at both high schools, Elizabethtown was a mechanical upgrade at an elementary school, districtwide LED lighting, building envelope, equipment/piping insulation, building system optimization, and a solar field.

Aside from the construction and energy savings, I can’t say enough good about McClure. From the people on their sales and engineering team, to their service, and being an overall great partner that will help me with whatever situation I’m in. I consider them my long-term partner that I can rely on for honest feedback with the district’s best interest first, not the sale.
