The cost of a repipe depends on how many fixtures the house has, what the walls and floors are made of, which pipe you choose and what has to be repaired afterward. A small single-story home with open attic access costs far less than a large two-story house with finished walls.
We do not post a fixed number, because a number without a visit would be a guess. We give a clear price before work starts. Call (805) 249-7135 and describe the house, and we will tell you what to expect.
The six factors that set the price
When you compare quotes, make sure each one covers the same scope. A low quote that excludes drywall and permits is not lower, it is shorter.
PEX or copper: the cost trade-off
| Material | Upfront | Install speed | Notes |
|---|---|---|---|
| PEX | Lower | Fast, flexible runs | Most common for whole-house repipes |
| Copper | Higher | Slower, requires soldering | Long record and a metal look |
| CPVC | Lower | Fast | Less common, can become brittle |
Our repiping page compares materials in more detail. Whatever you choose, ask what warranty covers the pipe and what covers labor.

Repair, partial repipe or whole house
One leaking section in sound pipe is a repair, and a repair costs the least. When pipes fail in many places, repairs add up, and a repipe becomes the better value over a few years. A partial repipe replaces the worst sections, such as a bathroom group or a service line.
If you are asking because a pipe has just burst, start with burst pipe repair, and decide on the larger project once the water is stopped and the damage is clear.
Lompoc local note: permits and the water you are piping
The City of Lompoc building division says any addition or relocation of water, sewer, gas or electrical lines always requires a permit, and plumbing work in general requires one. Ask the counter how your repipe will be classified, since inspections are part of the timeline.
The city's 2025 water quality report lists a pH near 8.4, average hardness near 293 ppm and sulfate near 424 ppm. In August 2025 its lead and copper sampling of 32 homes found no sites over the action levels. That describes the supply, not your interior pipe, so inspect the pipe itself before deciding how much to replace.
What insurance might cover
Most homeowner policies do not pay to replace aging pipes. They may cover sudden water damage that results from a failure. Read your policy and ask your insurer before you decide, and keep receipts and photos of any damage.
Some owners consider repiping before a major remodel, since walls are open anyway. That can reduce the drywall cost portion of the project. Talk with your general contractor about sequencing.
Questions to ask every contractor
- Is the permit included, and who pulls it?
- Does the quote include drywall patching and paint?
- What pipe material and fittings will you use?
- How many days will the water be off and for how long each day?
- What warranty covers labor, and what covers materials?
- Who inspects the work and tests the pressure?
Write the answers down and compare them line by line. If a contractor will not answer plainly, that is information too. A clear price before work starts is the standard we hold ourselves to, and you can ask any plumber for the same.
Planning around a repipe
Plan for a few days of disruption. Move furniture away from walls where pipes run, and clear the area under sinks. Plan meals and showers around the hours when water is off. If you have pets or small children, ask about the work areas and dust control.
Take photos of the walls and ceilings before work begins. Ask the crew to mark access holes and discuss where they will be. A tidy plan with open communication prevents most complaints.
After the job, run every fixture and check for stains or drips over the next week. A good contractor will come back to fix any leak they missed.
Why quotes differ so much
Two contractors can walk the same house and return numbers that look far apart. The gap usually comes from scope and assumptions. One may plan to open walls in every room and another may route most pipe through the attic. One may include every fixture shutoff and another may reuse the old ones.
Ask each contractor to list the fixtures covered, the pipe material, the manifold or trunk layout and the patching included. Then compare the lists, not just the totals. A clear price before work starts only helps if you know what it covers.
Also ask about change orders. Hidden damage behind a wall can add work, and a good contractor explains how that would be priced before it happens.
Signs it is time to consider a repipe
- Repeated leaks in different parts of the house.
- Discolored water that returns after flushing.
- Low pressure that does not improve after fixture repair.
- Pinhole leaks in copper.
- Galvanized steel or polybutylene pipe still in use.
- Visible corrosion at joints and valves.
One of these alone may not justify a repipe. Several together usually do. A plumber can test pressure, inspect exposed pipe and offer an honest opinion on remaining life.
How long it takes and what to expect
- Most houses take one to three days.
- Water is off for part of each day, and we tell you when.
- Small access holes are cut in drywall, and patching is separate unless included.
- A final pressure test confirms the new lines before walls are closed.
- A city inspection may be required.

Questions homeowners ask
Access, pipe condition and fixture count change the number. We give a clear price after we understand the house.
The City says additions or relocations of water lines always require a permit, so confirm with the building counter.
Yes. A partial repipe replaces the worst sections.
Usually not for worn pipe, but possibly for sudden resulting damage. Ask your insurer.
The 2025 report lists average hardness near 293 ppm. Scale narrows pipes over time, but many failures come from old steel and fittings.
Compare scope, material, permits, inspection, patching and warranty. A lower number may exclude items.
