Koan Builders

Koan excavated my old garage foundation, built my new garage foundation, and installed french drains to help with the drainage around my garage. Koan did an incredible job. Their work product is top notch. Dave and Keelan are both good people and great to work with. They're communicative, organized, professional, and trustworthy. Dave is meticulous, thorough, and very thoughtful about every aspect of the job onsite. In addition to the garage, Dave highlighted some water drainage issues on my property and recommended ideas to prevent future problems. The crew was hard working, efficient, and respectful. My job created a huge mess between the demolition, rain, and snow. The crew cleaned up every day so my neighbor's couldn't complain. I would highly recommend Koan to anyone with a concret

Dave and his crew from Koen Builders have done several jobs for us. First was a driveway and sidewalk. Next they poured an RV pad. Lastly they created a beautiful concrete patio in the backyard. The patio was a huge project which included new roof support beams, a tear out of our old concrete patio and a new colored poured patio. Prior to the new patio we were constantly plagued by rain water coming into our basement. Dave and his team designed and installed a French drain system. No more water problems!! They did a phenomenal job! We were impressed how quickly all jobs were completed. We highly recommend Koen Builders. They are fair, trustworthy and efficient. Photos attached are of the driveway and the backyard patio. Well done Koen Builders!!!

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.

Dave and his crew were wonderful to work with. Dave helped with some design issues and offered wonderful solutions. The crew cleaned up after themselves. The only trace they were there was this beautiful new walkway and stairs.
