Comments from a few satisfied customers...


"Ryan was the best, and I've dealt with many contractors in my life. He listened to my needs, answered any questions I asked, did not try to sell me anything I did not need or want and communicated his experience preventing me from making mistakes. He had all work done in a professional and timely manner. I would recommend him to anyone, even my family, need I say more?"

"Ryan Koster was extremely professional, pleasant and efficient. His decking crew were equally professional, pleasant and efficient and built exactly what I had designed to perfection - I have absolutely no complaints and would highly recommend Koster Konstruction to anyone who needs additions or remodeling to their home.

"(Koster) Konstruction was an amazing contractor. He showed up when he was supposed to show up his quality work was excellent and his interpersonal approach and caring attitude made our project seemed as though it was his own. Ryan was exceptionally Fair in his assessment of the work as well as this proposal to complete the work. He was also very flexible."

"We started a DIY project in our guest bathroom, unable to complete so we called in the pros! They came in the next week, completed the drywall, plumbing, painting and install of vanity, toilet and tile on the wall and floor... Ryan had a new pro in and out for each project. The project started on a Thurs and they were done by Monday. Very impressed with the work, especially for the cost!"
