If your St. Louis home has original galvanized pipes, recurring pinhole leaks in copper, or persistently low water pressure from corroded supply lines, whole-house or partial repiping is the permanent solution. STL Plumbing Pros replaces failing pipe systems with modern PEX or copper — restoring water pressure, eliminating rust, and preventing future leaks.
Signs You Need Repiping
Rust-colored water from multiple faucets — galvanized pipes corroding from the inside.
Recurring leaks in different locations — patching individual leaks is no longer cost-effective.
Low water pressure throughout the house — pipe interior narrowed by corrosion deposits.
Visible corrosion, green patina, or white mineral deposits on exposed pipes.
Home built before 1970 with original galvanized supply piping.
Our Process
Assessment & Planning
We map your existing piping, identify the best routing for new lines, and provide a detailed quote. We plan to minimize wall access and disruption.
Install New Piping
Working room by room, we install new supply lines (PEX or copper), connect to fixtures, and restore water service at the end of each work day.
Test & Finish
Pressure test the entire system, check every fixture for proper flow, and patch any access holes. Your home is left clean and fully operational.

What Our Customers Say
"1950s home with galvanized pipes — low pressure, rusty water. They repiped the whole house with PEX in 3 days. Like having a new home."
"Had our fourth pinhole leak in 2 years. Decided to repipe instead of keep patching. Best decision — no more leak anxiety."
"They worked room by room and we had water every evening. Minimal disruption for such a big project."
