California’s aging housing stock means galvanized steel, early copper, and even polybutylene pipes are still hiding behind many walls. Leaks, low pressure, rusty water, and constant pin-hole repairs push homeowners to ask the same question: how much to repipe a house in California? CountBricks delivers a clear, data-backed answer by combining AI takeoffs, live material pricing, and on-site voice capture to build rock-solid estimates in minutes. Below, we break down every cost driver so you can compare figures with confidence.
• PEX: Flexible, fast to install, and earthquake-friendly. Typical supply cost ranges from $0.40–$0.60 per linear foot, keeping the average 3-bedroom home between $4,000 and $9,500 installed.
• Type L Copper: Premium durability but higher raw cost. Expect $2.50–$3.50 per linear foot, landing most homes between $10,000 and $18,000.
• CPVC: Less common on the West Coast but still an option. Pricing sits between PEX and copper.
• Condos and small bungalows (under 1,400 ft²) may only need 150-200 linear feet of new line, trimming labor and materials.
• Larger two-story homes (2,400 ft²+) often require 350-450 linear feet plus additional vertical runs, driving totals up by 25-40 %.
1. Open basements and crawlspaces reduce drywall cuts and labor hours by roughly 15 %.
2. Slab-on-grade construction requires overhead runs or partial trenching, adding demolition and concrete patching fees.
California’s strict Title 24 plumbing standards mean pressure balancing valves, seismic strapping, and lead-free fittings are non-negotiable. Permit fees usually fall between $300 and $900, varying by county.
• Standard patch and texture: $2–$4 per square foot of affected drywall.
• Premium finishes (Venetian, high-end tile): budget an extra 10-15 % to blend repairs seamlessly.
• Two-bed, one-bath bungalow in Los Angeles: $6,800–$9,200 with PEX, full trenchless pull via attic, and basic drywall restoration.
• Four-bed, three-bath suburban home in Orange County: $11,500–$16,000 using Type L copper, partial slab saw-cutting, and premium texture matching.
• Mid-century hillside property in San Diego with limited access: $18,000–$24,000 after seismic upgrades, multi-story scaffolding, and upgraded fixtures.

Yes. CountBricks crews reroute water so at least one bathroom remains active. We schedule short shutdown windows during school hours or workdays whenever possible.
After repeated leak claims, many carriers encourage proactive repiping. CountBricks provides documentation packets to submit with your policy.

When the Fernandez family bought their 1924 Craftsman, they loved the original woodwork but not the rusty laundry water. They asked, “How much to repipe a house in California of this vintage?” In 22 minutes, CountBricks LiveView captured every run length while our estimator spoke into a headset. The AI generated three options:
• PEX solution at $8,900 with a three-day schedule
• Hybrid PEX/copper upgrade at $11,200
• Full Type L copper with seismic bracing at $14,600
1. PEX in walls reduced wall demo by 30 %.
2. Exposed basement ceiling allowed sweat-braised copper mains for longevity.
3. CountBricks showed live supplier rebates, trimming $450 from copper fittings the same day.
• Demo started 48 hours after permit release thanks to our internal code desk.
• Voice-logged progress notes synced to the homeowner portal nightly.
• Drywall team matched 100-year-old plaster texture using CountBricks historical finish library.
