Replace Failing Pipes Before They Fail Completely

Whole-home repiping services in San Jose for older and deteriorating plumbing systems

If your home was built in the 1960s or 1970s, there is a good chance the original plumbing is still in the walls, and you have noticed rust-colored water, inconsistent pressure, or small leaks that keep coming back. Cervantes Construction replaces aging plumbing systems throughout San Jose, pulling out corroded galvanized pipe and installing new copper lines that will last decades without the same problems.

This service involves removing old supply lines and running new copper piping to every fixture in your home. It is ideal for homes preparing for a remodel, properties with recurring leak issues, or buyers who want to address plumbing before move-in. The work is done in sections to keep water available during most of the project, and all connections are pressure-tested before walls are closed.

If you are tired of patching leaks or dealing with weak water flow in your San Jose home, reach out to Cervantes Construction for a repiping estimate.

How the Work Is Sequenced and Completed

The job begins with an inspection of your existing system and a walkthrough to determine where new lines will run in your San Jose home. Access points are identified, and the schedule is planned to limit how long water service is interrupted each day.

Once the new copper piping is installed and tested, you will notice consistent water pressure at every faucet, no more discoloration, and a system that does not require constant monitoring. The work is organized to minimize dust and damage, and any drywall or flooring disturbed during installation is noted for repair coordination.

All piping is routed to code, and inspections are scheduled as required by the city. If your home includes a second story or complex layout, the routing plan is adjusted to avoid unnecessary wall demolition while still delivering full coverage.

What You Should Know Before Starting

Homeowners usually want to understand how long the work takes, what will be opened up, and whether they can stay in the house during the project.

How long does a whole-home repipe take?
Most single-story homes take three to five days, depending on size and layout. Two-story homes or homes with complex plumbing may take longer, and you will receive a timeline during the estimate.
What happens to my walls and ceilings?
We open only what is necessary to access old piping and install new lines. All openings are marked and can be patched by your contractor or ours, depending on your preference.
Why is copper recommended over other materials?
Copper piping is durable, code-compliant, and performs well in San Jose homes for decades without the degradation seen in galvanized steel. It also handles pressure changes better than some plastic alternatives.
Can I use water during the project?
Water is typically available in the evenings and overnight. We work in sections so that service is only fully shut off during active installation hours.
When is repiping recommended before a remodel?
If your home is over 40 years old or you have seen recurring leaks, it makes sense to repipe before opening walls for other work. It saves time and avoids future disruption.

Cervantes Construction has repiped dozens of homes across San Jose, including properties preparing for sale, mid-century homes with original plumbing, and remodels where updated infrastructure was part of the scope.
