WHO WE ARE

IMG_1474.jpeg

Since Carl Coffman founded our company in 1979, Coffman Excavation has grown from a specialist in residential septic systems to a full-service contractor specializing in site preparation and roadway construction.

 

From small scope projects to major public works endeavors, we have gained a reservoir of knowledge that only four decades of experience can impart.

Our longevity in the marketplace and collaborative project approach has created enduring partnerships that are based on loyalty and trust.
