What our Clients are Saying

“We could not have been happier with our experience working with G. Christianson. Super organized. Professional. Super high quality work. Responsive. Kind and generous. We had one point of discussion that was handled quickly, professionally and with equanimity. Our kitchen remodel has changed our home, not only structurally but how we live here. And that could not have been done without the good folks from G. Christianson.”

“They took our period bathroom and built a gorgeous and accessible shower with great sensitivity to the historic details. They left no mess, and finished every detail perfectly. They adapted to small changes we suggested and made errors right. Tony, especially, was just terrific to work with and the cabinetmaker was a master!”
