We replace corroded, leaking or outdated water supply pipes with new lines planned around your home's layout. If repeated leaks, rusty water or weak pressure keep coming back, a repipe fixes the source instead of patching one spot at a time.
Repiping means replacing the old water supply lines in a home and running new pipe to every fixture that needs it. Our repipe specialists start by tracing where the existing lines run, what they are made of and where failures are showing up. That lets us size and route the new system for how the house actually uses water, so the weak points that kept causing trouble are gone.
Most homes reach this point gradually. Galvanized steel corrodes from the inside and narrows the pipe. Older polybutylene can become brittle, and copper can develop pinhole leaks over time. Once failures appear in several places, chasing individual leaks can mean opening walls again and again. A planned repipe deals with the whole run at once.
We check visible pipe, test pressure at fixtures and look at where leaks or discoloration are appearing. That tells us whether the whole system is failing or only one section needs new pipe.
New supply lines run from the main shutoff to every fixture and replace corroded or brittle pipe throughout the house. Access openings are planned in advance so walls are opened only where the new routing requires it.
When failures are confined to one area, such as a kitchen run or a bathroom group, we replace that section and connect it cleanly to sound pipe. This keeps the scope matched to the actual problem.
A repipe is a planned project, not a quick swap, so the plan is part of the job. Before work starts, you see which lines are being replaced, which pipe material we recommend and why, and where access openings will go. We also explain how water service will be handled while the work is underway. Nothing in the scope changes without a conversation first.
On the job, the sequence stays consistent. We shut off the supply, open access points, then run and secure the new pipe. Next we connect each fixture and pressure-test the system before anything is closed up. When we finish, we walk you through the completed work, show you the new shutoffs and explain any wall or ceiling patching that remains.
What homeowners usually ask before replacing their water lines.
How do I know if my house needs a repipe instead of a repair?
Repeated leaks in different spots, rusty or discolored water from several taps, and pressure that drops across the whole house all point to a system-wide problem. A single leak at one fitting is usually a repair. A pattern of failures is where repiping makes sense, and an inspection of the pipe material and condition settles the question.
Should I choose copper or PEX for repiping?
Both are common for water supply lines. Copper is rigid and long established. PEX is flexible, which can mean fewer fittings and fewer wall openings when routing through finished spaces. We recommend a material based on your home's layout, access and priorities, and we explain the tradeoffs before work starts.
Will you have to open my walls?
Some access openings are usually needed to reach the old pipe and route the new lines. We plan the openings in advance to keep them as few and as small as the routing allows. We also explain up front what patching will remain afterward.
Can I stay in my home during a repipe?
Often, yes. The main inconvenience is that the water is shut off during parts of the work. We explain the sequence ahead of time so you know when service will be interrupted and when it will be restored.
What affects the cost of repiping?
Cost depends on the size of the home, the number of fixtures, the pipe material, how many floors the lines run through and how easy the existing pipe is to reach. A partial repipe costs less than whole-home work because it involves less pipe and fewer openings. We provide a scope-based quote after the assessment.
