Cons: UV sensitive (not for outdoor use), not recyclable. Best for: Most homeowners, especially in cold climates.
Copper: Premium choice (15% of projects). Cost per sq ft: $8.00-$14.00. Lifespan: 70+ years. Pros: Traditional, durable, recyclable, doesn't leach chemicals, high heat resistance. Cons: Expensive (40-60% more than PEX), requires soldering (fire risk), can corrode with acidic water, freeze-prone. Best for: Historic homes, buyers who prefer traditional materials.
CPVC (Chlorinated Polyvinyl Chloride): Budget choice (8% of projects). Cost per sq ft: $4.00-$8.50. Lifespan: 40-50 years. Pros: Budget-friendly, rigid, good chemical resistance, easy installation.

Factors That Increase Repiping Cost

Home Size (Largest Factor): More square footage = more pipe length = higher cost. Each additional 500 sq ft adds approximately $1,500-$3,500 to PEX cost, $3,000-$7,000 to copper cost.
Number of Bathrooms: Each additional bathroom adds $800-$2,000 to total cost due to extra fixtures and pipe runs.
Number of Floors: Multi-story homes require additional labor for accessing upper floors through walls and ceilings. Add $500-$1,500 per floor.
Access Difficulty: Slab foundations cost more than crawl spaces or basements because pipes must be run through ceilings or walls. Add 15-25% to total cost.
Limited Access: Tight attics, cramped crawl spaces, or finished basements increase labor time by 30-50%.
Water Heater Replacement: Standard water heater $2,200, tankless $3,500. Often recommended during repiping.

How Long Does Whole House Repiping Take?

1,500 sq ft home (2 bathrooms): 3-5 days. 2,500 sq ft home (3 bathrooms): 5-7 days. 4,000+ sq ft home (4+ bathrooms): 7-10 days. PEX installation is faster than copper (30-40% time savings). Most homes are without water for 8-12 hours during the main water line connection. Plumbers typically work 8-hour days and will schedule water shutoff for daytime hours only. Plan for the inconvenience and consider staying elsewhere during the project if you have young children or medical needs.

Does Repiping Increase Home Value?

Yes, repiping typically increases home value by $10,000-$25,000 depending on home size and market. Homes with updated plumbing systems sell 15-20% faster and at 5-10% higher prices than homes with aging galvanized or polybutylene pipes. New PEX or copper piping: Eliminates buyer concerns about leaks and water damage, improves water pressure, modernizes the home, and is a major selling point during home inspections. ROI typically 80-100% of project cost. Many real estate agents recommend repiping before listing older homes.
