How Much Does It Cost to Repipe a House in Los Angeles?
Repiping a typical Los Angeles home costs $6,000 to $15,000 with PEX and $10,000 to $25,000 with copper. A 1,500 to 2,000 square foot house with 2 bathrooms often lands around $8,000 to $12,000 in PEX. Size, number of bathrooms and wall repairs drive the final price.

What drives the price
- Number of bathrooms and fixtures. Each fixture adds pipe runs and connections.
- One story or two. Two-story homes need more wall openings to reach upstairs lines.
- Access. A raised foundation or attic makes routing easier. Slab homes often route new lines through the attic and walls.
- Drywall and paint repair. Some quotes include patching. Others leave it to you, which can add $1,000 to $3,000.
- Permit. Repipes in the City of LA require an LADBS permit and inspection, often a few hundred dollars.
Signs you need a repipe
- Two or more pinhole or slab leaks in a few years
- Rusty or brown water, especially from hot taps
- Low water pressure throughout the house
- Original galvanized steel pipes, common in LA homes built before about 1960

Frequently asked questions
How long does a repipe take?
Most single-family homes take 2 to 5 days. Many plumbers restore water at the end of each day.
PEX or copper?
PEX costs less, installs faster and resists freezing and scale. Copper lasts a long time and some buyers prefer it. Both meet California code when installed correctly.
Will insurance pay for a repipe?
Usually not. Insurance may cover sudden water damage from a leak, but replacing old pipes is typically treated as maintenance.
Can I stay in the house during a repipe?
Usually yes. Expect some noise, dust and open walls, and water shut off for part of each day.
