How much does a whole-house repipe cost in San Jose?
A whole-house repipe in the San Jose / Bay Area typically ranges from about $4,000 to $15,000 or more, depending on the size of the home, the number of bathrooms, the pipe material (PEX vs. copper), and accessibility. The best way to get an accurate number is a free in-home estimate. Gladiator Repipe offers free consultations and financing options.
Is PEX or copper better for repiping?
Both are excellent. Copper (Type-L) is durable, time-tested, and corrosion-resistant, while PEX is more affordable, flexible, freeze-resistant, and faster to install. Copper often suits homeowners wanting maximum longevity; PEX suits those prioritizing cost and efficiency. A qualified repipe specialist can recommend the right material for your home and budget.
How long does a whole-house repipe take?
Most whole-house repipes are completed in 1 to 3 days, depending on the size of the home and the number of fixtures. Experienced repiping crews minimize disruption and typically restore water service by the end of each work day.
How do I know if a San Jose plumber is licensed?
Every legitimate plumbing contractor in California must hold a license from the Contractors State License Board (CSLB). You can verify any company’s license number for free at cslb.ca.gov. Gladiator Repipe & Plumbing holds CSLB license #1008291 and is fully insured.
