Martex is the name of our signature product.

At Ordaz General Marble & Granite, Inc., we’re best known for our custom work, but we do it all-- including counter tops, bath tubs, shower pans, vanity tops, and more. Each and every client has its own specific goals and needs and that’s why we never take a “one size fits all” approach to any job. Everything we do is essentially “custom work” because no project is ever identical.

Client Review

Our customers aren't afraid to tell the world that we've done a great job for them,
because they value our quality, work ethic and skills.


My contractor recommended Ordaz with good reason.  Unbeatable quality, prices and personal service.  You can tell Carlos is passionate about his work and products they manufacture personally in their shop.  I was a little leery of marble, but when Carlos explained that the cultured onyx would not fade, needed little cleaning, and was as strong as granite, I was sold.  Even my hubby who was not fond of the idea loves the way it turned out.  Some friends actually thought it was real granite slabs. 

Carlos and his crew were meticulous, fast, and flexible.  He knew we were in a hurry for this unplanned shower remodel and was willing to install on a Sunday morning, but instead squeezed us in on the Saturday at 5:00 so his guys could have Sunday off.  Despite the late hour, the install was perfect! 

There is a reason this family owned business has been around for more than 25 years.  Wish all businesses were this good!  The only negative thing I can say is I wish the showroom were still in Pleasanton.

Will definitely call them again when another bathroom is in need and recommend to friends. Thanks Carlos!
