THE MATH
Whole-house repipe cost formula
Total = length × (material + labor) + fixtures + wall repair + permitsPEX runs ~$2/ft, copper ~$3.50/ft. Labor averages ~$6/ft and rises with floors and access difficulty (x1.15 moderate, x1.4 difficult). A 350 ft house on 2 floors is a common starting point.
PRACTICAL EXAMPLE
350 ft repipe in PEX, 2 floors, moderate access
Materials = $700. Labor = 350 × $6 × 1.2 × 1.15 = $2,898. Fixtures = $2,500. Wall repair = $1,800. Permits = $500. Total = $8,398.
