Job-site craft: sequencing with the other trades, protecting the home, and the punch list that ends the job
Half of a plumbing business's reputation is made after the pipe is right: whether the plumber showed up the morning the framer finished, whether the hardwood was covered, whether the customer's last impression was a clean garage and a walk-through or a missing escutcheon and a text three days later. This lesson is the craft that the code does not grade and the customer does: the sequence on a remodel and how a plumber fits into it, the protection of the home that is both courtesy and, in a pre-1978 house, law, the inspection sequence as a schedule, and the punch list that turns the final walk-through into the final payment and the review.
What the full lesson covers
- On a remodel, the plumber's three visits (underground, rough, trim) each sit between other trades; the sequence is posted, the dates are on the contract, and a day missed by the plumber is a week lost by the job.
- Nothing is concealed before inspection: no drywall over an uninspected rough, no backfill over an uninspected lateral, no slab over an uninspected underground. The inspector's schedule is the plumber's schedule.
- Protect the home like the lawsuit depends on it: floor protection from the door to the work, containment at the work area (mandatory containment in pre-1978 homes under RRP), drop cloths, shoe covers, a HEPA vacuum, and a photo of every room before and after.
- Discoveries on site are written change orders before the work, not surprises on the final invoice.
- The punch list is walked with the customer, every item is closed the same day or scheduled in writing, the final release goes with the receipt, and the review ask follows the walk-through, not the invoice.
