About this calculator
Polybutylene and galvanized pipes are the two most-likely inspection findings that force a whole-house repipe. Insurers increasingly refuse to cover polybutylene homes, and galvanized pipes restrict flow even when not leaking. This calculator estimates the realistic repipe cost — including the drywall, fixture, and access surcharges that surprise most buyers.
