We got a great deal from Expert Marble and Granite several years ago. I know they’re local and we were happy with the installation. http://www.emg206.com/
We also used expert marble and granite for our soapstone countertops last summer and they did a great job, were competitively priced and a pleasure to work with. Also loved that we were supporting a local West Seattle business owner.
I would HIGHLY recommend Sam Clark with Clarkstone. He has done several projects for us including bathroom counters and shower, fireplace surrounds and kitchen counters/backsplashes…. He lives local in West Seattle and worked for Caccalori Marble for about 20+ years. 206-954-7008
