Repiping is what our crews do every week.
Most of the homes we repipe were built between the 1960s and the 1990s, and almost all of them still run on their original copper or galvanized pipe. That pipe is 30 to 60 years old now, and Orange County water is not doing it any favors. We have repiped more than 780 homes here since 2020, from the original El Toro tracts in Lake Forest to the master-planned streets of Mission Viejo. Nearly 1 in 5 of those homes is on a street where we had already repiped a neighbor. Houses built in the same year, with the same pipe, on the same water, tend to reach the same decision around the same time. When your home gets there, our dedicated repipe crews pull the permit, schedule the city inspection, and patch and texture the walls before we consider the job finished.
Problems We Solve
Here is what we actually see on repipe calls across Orange County, and what each one usually means.
Pinhole Leaks in Copper Pipe
The most common reason Orange County homes repipe. Thin-wall copper from the 1970s through the 1990s develops tiny pinholes as it ages, and once the first one shows up, the second and third are usually not far behind.
Slab Leaks
Warm spots in the tile, the sound of running water when everything is off, a water heater that runs all night, a meter that spins with every fixture closed. Hot water lines under the slab are a regular story in South County homes.
Galvanized Pipe in Older Homes
Homes built before about 1970 in Santa Ana, Anaheim, Orange, Tustin, and Costa Mesa often still carry galvanized steel that has been rusting from the inside for decades. It shows up as fading pressure, rusty water, and questions during escrow.
Low Water Pressure
When pressure drops across the whole house rather than at one fixture, the pipe itself has usually narrowed with corrosion or scale. New pipe restores the flow the house was built to have.
Rusty or Discolored Water
Water that runs brown after a vacation, or carries a metallic taste, is usually picking that up from the inside of aging pipe on its way to your faucet.
Repair Bills That Keep Coming Back
Once a home has had two or three leak repairs, the math starts favoring the permanent fix. We will tell you honestly which side of that line your home is on.

Here is the pattern we see: a pinhole leak gets repaired, then another shows up months later, sometimes right after a neighbor has been through the same thing. Add dropping water pressure or rusty morning water, and the pipe is telling you where it is headed. One leak is a repair. Two or three is a conversation about repiping, and we will walk you through it honestly.
