Before you sign

What to ask a San Jose contractor first

  1. 01

    Will every fixture, hose bib and appliance line be reconnected, including the water heater, ice maker and outdoor spigots?

  2. 02

    Is the main shut-off, pressure regulator and service line included, because leaving old components upstream undermines the new system?

  3. 03

    Which pipe material is proposed for the new distribution lines, and how does that material perform with local water chemistry?

Before anyone touches a pipe

Verify the license. It takes two minutes.

  • Who licenses the work: Contractors State License Board (CSLB).
  • Who pulls the permit: San Jose Planning, Building and Code Enforcement — the licensed contractor, never the homeowner.
  • What to ask for: the license number, the registered name behind it, and an insurance certificate issued to the property address.

Answers first

Repiping in San Jose — common questions

How do I know if my house needs repiping?

The usual triggers are the material itself (galvanized steel or polybutylene), repeated pinhole leaks across the system rather than at one spot, and discolored water at multiple fixtures. One leak in one place is a repair; a pattern across the house is a repipe conversation.

PEX or copper?

PEX installs faster, costs less in labor, tolerates freezing better and has fewer joints in walls. Copper has a longer track record and is preferred by some jurisdictions and some buyers. Local code, water chemistry and your resale plans all factor in — ask the contractor to justify the choice for your specific house.

How long does a whole-house repipe take?

For a typical single-family home, commonly a few days of pipe work plus separate drywall repair and inspection. Water is usually off only for part of each working day rather than continuously.

Do I need a permit for plumbing work in San Jose?

Permits in San Jose are issued by San Jose Planning, Building and Code Enforcement. As a rule, water heater replacement, gas work, sewer laterals and repiping are permitted work, while a like-for-like faucet or disposal swap usually is not. A licensed contractor pulls the permit — if one offers to skip it, that is the signal to stop.

Is PlumberCalifornia a plumbing company?

No. Independent licensed professionals perform and contract the work directly with you. PlumberCalifornia routes the request and links every page to the official California license register.

Does PlumberCalifornia charge homeowners anything?

No. PlumberCalifornia may be compensated by a partner when a homeowner connects with a professional through the site. That never changes what the contractor charges for the job.

Does calling create any obligation to hire?

None. A call or a callback request is a conversation, not a contract. Scope, timing and price are only agreed if you decide to proceed with the professional handling San Jose.

Are night and weekend calls handled differently in San Jose?

Requests route around the clock, but most contractors price after-hours work differently. Ask for the after-hours rate and a committed arrival window before agreeing to a dispatch.
