A countertop is measured once, cut once and set once, and every one of those steps is a chance for a different company to blame the last one. We keep all three inside our own stone crew. The person who templates the vanity is the person who sets it, and our project manager signs off the seam layout before the saw starts.
That matters most on hotel and multifamily work, where dozens of identical tops have to land in dozens of rooms on a rolling schedule. Our crew fabricates ahead of the floors being finished and installs the day the room is ready for it.
