“K-One is now my go-to company. Trustworthy, honest, knowledgeable, and detailed oriented.”
Lindsey, 2nd Story Addition

“We were pleased with the work of the K-One team from initial proposals and revisions through final stages. They did great work, worked to minimize their impact on our home and were very kind. We enjoyed working with them and are very pleased with the end result.”
Nick, 2nd Story Addition
