Why quotes vary
- • Access: a pipe behind drywall or under a slab legitimately costs multiples of an exposed one
- • Home age: galvanized or cast-iron plumbing takes longer and often reveals adjacent problems
- • Emergency timing: nights/weekends run 1.5–2x — if it can wait until Monday, it should
- • Fixture grade: builder-grade vs designer fixtures swing materials cost far more than labor
- • Code add-ons: expansion tanks and pans are sometimes required, sometimes padding — ask which code section
