Average Repiping Costs in Los Angeles (2025)
Whole-house repiping in Los Angeles typically costs between $4,000 and $15,000 for a single-family home. The wide range reflects significant variation in home size, material selection, accessibility, and the number of fixtures. Here are typical ranges: Small home (under 1,200 sq ft): $4,000–$6,500. Medium home (1,200–2,000 sq ft): $6,000–$10,000. Large home (2,000–3,000 sq ft): $9,000–$15,000. Homes over 3,000 sq ft or multi-story: $12,000–$20,000+.
Copper vs. PEX: Which Costs Less?
PEX repiping typically costs 20–40% less than copper repiping for the same home. This is because PEX is a flexible material that can run through walls with fewer fittings and less labor time. Copper requires more fittings, more precise cuts, and more installation time. However, copper carries a premium for its proven 50+ year track record and resistance to UV and rodents. Many homeowners choose copper for peace of mind, especially in higher-value homes.
What Factors Affect Repiping Cost?
Key cost factors include: (1) Home size — more square footage means more linear feet of pipe. (2) Number of fixtures — each bathroom, kitchen, and utility connection adds cost. (3) Foundation type — slab homes are more complex and expensive to repipe than homes with crawl spaces. (4) Accessibility — homes with finished walls throughout require more patching. (5) Material — copper vs. PEX (see above). (6) Permits — required in LA County and included in reputable contractor quotes.
What's Included in a Repiping Quote?
A complete repiping quote from Plumbing 405 includes: labor and materials, all new water supply lines from the main shutoff to every fixture, new supply stops under sinks and toilets, all building permits and city inspection fees, minimal drywall access openings and patching, pressure testing, and a workmanship warranty.
What is NOT Included in Most Repipe Quotes?
Most repiping quotes do not include: repainting walls (we patch and texture-match, but painting is typically a homeowner responsibility), replacing fixtures or valves beyond standard shutoffs, major drywall or tile restoration in bathrooms (if tiles must be removed), or any electrical work. Always ask for a detailed written quote that specifies exactly what is included.
Is the Cost Worth It?
For most homeowners with aging pipes in Los Angeles, repiping is absolutely worth the cost. The average repipe cost is recovered through: elimination of ongoing leak repairs ($500–$2,000+ per incident), reduced water bills from pinhole leaks, increased home value (repiped homes sell for more), and peace of mind. A repipe is a one-time investment that protects your home for 50+ years.
