Our 64 year old cupboards and drawers are beautiful!  I’m sure they are more beautiful now than when they were brand new.  Every penny spent was worth it.  Now we have to make the rest of our kitchen look as good as the work Diamond Prefinish, Inc. did.

Reviews / Testimonials

I was constantly having scheduling issues as well as color matching problems with my previous finishers. These are no longer issues for me, as scheduling is taken as seriously by Diamond Prefinish as it is by me and my clients.

Mike Zuber, Owner – Thatcher Woodworks, Seattle, WA

We have noticed that when working with Diamond Prefinish we move more efficiently and can often get the job done quicker! We have always been pleased with their finished product.

David Rice, Owner – DK Professional Painting, LLC., – Tacoma, WA

After using several other finishers in the past, I was finding myself having to settle for sub-par work much too often. But since I’ve been using Diamond, I see myself looking no further. All of my projects go there now. They are professional, knowledgeable, flexible and courteous.
