We recently bought a mid-century modern house in Scottsdale. Constructed of concrete masonry blocks, the house had 49 years' worth of paint and desert dirt on it, and Ramon and his brothers did a fantastic job at a very fair price restoring it to its original handsome gray. They were professional in every way, had all of the best equipment, and took great care to protect windows and doors, not over-blast any area, and keep the dust down as much as possible. Ramon's years of experience and pride in his work were evident from our initial consultation to our final "thank you" and "goodbye." We're so glad we chose Baja Sandblasting; they made what is an inherently noisy, messy process worry-free and gratifying. And the bonus is that they're really nice and were fun to have around for three days.
