Of course you deserve superb workmanship, and in a timely manner. But whether it's delivery of the new tub before noon or the envisioned placement of a switch plate, nothing will ever be perfectly perfect. "We explained that custom cabinetry could never look like an airbrushed photo in a catalog," one source says of a prickly client. "It is handcrafted, after all." But she had the cabinets remade—twice. If you suspect that you, too, qualify as "tightly wound," start with a realistic calendar—your pro can help—and be glad if the tub arrives before he's off to his next job.
