What Our Clients Say
Trusted across Sandpoint & Bonner County.
“They showed up exactly when they said they would and knew right away how to handle the granite we'd been warned about. Our foundation dig was done in two days flat.”
“We had no idea our lot had that much rock under the topsoil. Curtis walked us through the plan before anything moved and the price didn't change once work started.”
“Snowmelt used to pool right next to our garage every spring. One afternoon of grading and it's never been a problem since. Straightforward crew, fair price.”
