Dave and the team are pros! In 5 days over the 4th of July holiday nonetheless they excavated my old driveway/garage slab, prepped for a new driveway/slab, poured both, and laid conduit for my underground electrical and communications cable. I am really happy with the final product and highly recommend them.
Koan did a great job helping us finish our landscaping. They added onto our driveway, built a retaining wall, and poured new pads in our backyard. The pricing was great, the price was exactly what was quoted, they were great about communicating, and they made every timeline estimate.
