Replacing galvanized plumbing costs $2,000 to $15,000 for a typical home.
Replacing galvanized plumbing typically costs between $2,000 and $15,000 for a standard single-family home. Galvanized pipes corrode over time, causing reduced water pressure, discolored water, and potential leaks. Replacement is recommended when pipes are over 50 years old or show signs of deterioration. The process involves removing old pipes and installing new copper or PEX piping throughout the home.

| Partial replacement | $1,000 - $5,000 | 1-2 days |
