Whole House Repiping
Done Right - Guaranteed

What repiping actually means

Repiping replaces the water supply lines running through your walls, ceilings and crawl space, rather than patching one failure at a time. It is the permanent fix for galvanized steel that has corroded shut, copper developing pinhole leaks, or a house that has simply reached the end of its original plumbing life. In most Bay Area homes the job takes one to two days, with water restored the same evening.

What it costs

A whole-house water repipe in the Bay Area typically runs $5,500 to $33,500 and up. That is a wide band because three things move the number: how many fixtures and bathrooms you have, whether the house sits on a slab or a raised foundation, and whether you choose PEX-A or L-grade copper. A single-story home on a crawl space sits near the bottom of that range. A two-story home on a slab, where new lines route through the first-floor ceiling, sits nearer the top.

Gas repiping runs $1,800 to $18,000 and up, priced by appliance count and run length. Sewer line replacement runs $3,500 to $21,500 and up. You can narrow any of these to your own home with the repipe cost calculator in about a minute.

How to choose a repipe contractor

Repiping is one of the larger jobs a homeowner will ever authorise inside their walls, and the quality gap between contractors is wide. Five things separate a good bid from a risky one:

• An active CSLB licence you can verify. Look it up yourself on the CSLB website rather than taking a number on a truck at face value. Ours is #1057926.
• Permits pulled and inspection scheduled. Unpermitted plumbing surfaces later, during a sale or an insurance claim. A contractor who offers to skip the permit is offering you the problem.
• A warranty covering parts and labour. A manufacturer warranty on the pipe alone leaves you paying for the wall to be opened again. Ours is 25 years on PEX and 30 years on copper, parts and labour both.
• Drywall patch and texture written into the quote. Opening walls is unavoidable. Closing them properly is where cheap bids quietly leave you with the bill.
• Repiping as a specialty, not a sideline. A crew that repipes weekly works faster and cleaner than a general plumber doing a handful a year.

Repipe or keep repairing?

The usual tipping point is frequency. One leak in a decade is a repair. Two or more calls a year, discoloured water, or pressure that keeps dropping means the pipe material itself is failing, and each patch buys less time than the one before. Galvanized steel has a 40 to 50 year service life, so most Bay Area homes built before 1990 are at or past it.
