Will & Nikki C.

Wesner Excavation has done a number of jobs for us. Their quality work is both timely and efficient. With a breadth of equipment and extensive knowledge, there is no job too big or small. He embodies device with a smile and is a pleasure to work with.

A company that is trustworthy, courteous and hardworking. Scope of work was always clearly communicated and pricing has been competitive.  But most importantly, work performed whether it's septic, road work or earthwork, was done right the first time and within budget.
