Again we used Washington Marble and Granite - this time for our kitchen. Mike was wonderful to work with and very helpful to get the right design and layout. Val and Juan came for the install and were respectful and courteous taking their time to remove the other granite. I can't say enough about the quality of work and assistance from this company. i wouldn't use anyone else. My kitchen is brighter and so beautiful! Used this company for our Master Bath. Best customer service, great selection, courteous staff. Quality all the way!

They did an amazing job installing our new quartz kitchen counters. Perfect placement of the seams and it was measured so accurately that the job was perfection! They were great about coming back quickly when one small area needed cleaning and a bit of polishing. The installers were very professional and friendly! Highly recommend them!
