🎨

DIY Finishing

Handle drywall repair and painting yourself. Saves $2,000-$4,000. Plumbers patch holes, you finish.

📊

Smart Material Choice

PEX saves 40-50% over copper. Equal performance for most homes. Faster installation = lower labor.

🏠

Partial Repipe?

Sometimes possible for problem areas only. Galvanized to water heater. Kitchen zone only. Assess carefully.

Frequently Asked Questions

Expert answers to common repiping questions

How do I know if I need whole house repiping vs repairs?
Need repiping if: Multiple leaks per year, pipes are 40+ years old (galvanized) or any age polybutylene, low pressure throughout house, discolored water from multiple taps. Repairs work for: Isolated leaks, newer pipes (under 20 years), single fixture issues. Rule of thumb: If repair costs exceed $2,000/year or you’ve had 3+ leaks, repiping is more cost-effective long-term.
What’s the best pipe material for repiping?
PEX is best for most homes: costs 40-50% less than copper, installs faster (less labor), resists freezing, 50+ year lifespan. Choose PEX-A for cold climates (most flexible). Copper still best for: exposed pipes, outdoor runs, where code requires. CPVC okay for budget jobs in warm climates. Avoid: anything not code approved, used materials, mixing incompatible metals.
Can I live in my house during repiping?
Yes, most people stay home during repiping. Water is restored each evening, one bathroom usually stays functional. Expect: 4-6 hour water shutoffs daily, noise and workers 8am-5pm, dust from wall openings, furniture moving. Tips: Stock bottled water, plan shower times, protect belongings with plastic, communicate needs with crew. Only 10-20% of homeowners relocate.
How long does whole house repiping take?
Typical timeline: Small home (1-2 bath): 2-3 days piping + 2-3 days drywall. Average home (2-3 bath): 3-5 days piping + 3-4 days finishing. Large home (3+ bath): 5-7 days piping + 4-5 days finishing. Factors affecting time: slab vs crawlspace, single vs multi-story, occupied vs vacant, weather (for external work). Most jobs complete within 2 weeks total.
Does repiping add value to my home?
Repiping adds $5,000-$10,000 in appraised value but main benefit is marketability. Buyers fear old pipes – major negotiation point. New pipes: eliminate inspection concerns, reduce insurance costs, prevent deal-killing surprises. For selling: market as “completely repiped” – powerful selling point. Keep all documentation and warranties for buyers.
Will insurance cover repiping costs?
Insurance rarely covers preventive repiping but may cover: damage from pipe failure (water damage), repiping after covered incident, partial costs if pipes fail. Won’t cover: age-related replacement, polybutylene replacement, gradual deterioration. However: some insurers require repiping for coverage, others offer discounts for new pipes. Check policy and discuss with agent before major leaks occur.
What about just repiping the hot water lines?
Partial repiping possible but consider: hot lines often fail first (more corrosion), but cold lines same age. Cost savings minimal: still need permits, wall access, labor mobilization. Maybe worthwhile if: hot lines are different material, cold lines recently done, severe budget constraints. Most plumbers recommend complete job – only 20-30% more for all pipes.
