"Diego and his crew are amazing! Punctual, fair price and just a great job all around. I even had other contractors come through who commented on what a great job they did. At one point we were on a very tight timeline and needed the remaining plaster installed before the floors went in. Diego’s crew worked late on a Saturday to make sure it was done. Simply could not have stayed on schedule without him."
