“Sia and his team from Step Up Concrete and Construction were great to work with! They were on time for every appointment. They took great care of my property and belongings. I had a very tight workspace, and they had to work sometimes on their tiptoes, yet they turned out exactly what I had asked for with skill and finesse. I highly recommend them!”
“I have now used Step Up twice Once for a breakdown of a front concrete patio area that involved breakup and take away and a whole new set up And I was impressed with some details that made it pop that I did not ask for And more recently had them extend a cement slab and do an overlay of the older area and the work was impeccable Great communication Good clean up And quality work”
