How long does whole-house repiping take?

Most residential repipes take 2–4 days for the plumbing work. A 2-bathroom home typically takes 1–2 days; a 4-bathroom home may take 3–5 days. Water is turned off during active pipe work but restored each night in most cases. Drywall patching happens after the pipe inspection passes — add another 1–3 days for a painter if you're repairing walls. The plumber should pull permits; inspection typically adds 1 business day to the schedule.

Is PEX or copper better for whole-house repiping?

For most homeowners, PEX-A is the better value choice: 40–50% lower material cost, superior freeze resistance (PEX expands rather than bursting), easier installation in tight spaces, and a 25-year manufacturer warranty. Copper is preferred when local water chemistry is aggressive (low pH), when resale value in your market favors copper, or when local codes restrict PEX. PEX cannot be used for gas lines and must maintain clearance from heat sources.

What signs indicate a whole-house repipe is needed vs. spot repairs?

Spot repairs make sense for an isolated leak on otherwise sound pipe. Whole-house repiping is indicated when: (1) pipes are original galvanized steel (50+ years old, now rusting from inside), (2) you see orange/brown water discoloration from multiple fixtures, (3) water pressure is low throughout the house, (4) you've had 3+ pinhole leaks in 5 years in copper pipes (common in aggressive-pH water areas), or (5) a plumber finds widespread corrosion in a partial repair. A repipe inspection (often free from repipe specialists) can confirm the scope.

Does homeowner's insurance cover repiping costs?

Standard homeowner's insurance policies cover water damage from a sudden pipe leak but typically exclude the pipe replacement itself, which is considered maintenance/wear. Some HO policies cover the cost to access the pipe (opening walls) but not the pipe. For older galvanized systems, some insurers require proof of repiping before renewing coverage or will exclude water damage claims from the original pipes. Read your policy's 'maintenance exclusion' clause and contact your agent before scheduling a repipe.

How Repiping Costs Are Estimated

Repiping contractors typically price whole-house projects using two components:

Core repipe cost = Fixture connections × Cost per fixture

Size allowance = Home square footage × $/ft²

Total budget = (Fixture subtotal + Size allowance) × Material multiplier × (1 + Contingency %)

This reflects real contractor pricing: a one-bathroom house with 10 fixture connections and 1,200 ft² costs less than a 4-bathroom 3,500 ft² home with 30+ connections.

Fixture Count Reference

Fixture Type	Connections
Kitchen sink	2 (hot + cold)
Dishwasher	1 (cold)
Bathroom sink	2
Toilet	1 (cold)
Tub/shower combo	2–3
Shower only	2
Washing machine	2
Water heater	2
Outdoor hose bib	1 each
Ice maker / fridge	1

Typical total connections: - 2-bed / 1-bath home: 15–20 connections - 3-bed / 2-bath home: 22–30 connections - 4-bed / 3-bath home: 30–42 connections

Material Cost Multipliers

Pipe Material	Multiplier vs. Baseline	Pros	Cons
PEX-A (Uponor)	1.0× (baseline)	Flexible, freeze-resistant, lower cost	Requires fittings, not all inspectors approve
PEX-B	0.85×	Cheaper than PEX-A	Less flexible, more prone to kinking
CPVC	1.1×	Rigid, glued joints	Brittle in cold climates
Copper	1.6–2.0×	50-year lifespan, resale value	High material cost, price fluctuates

Typical Cost Ranges (2024)

Home Size	PEX Repipe	Copper Repipe
1,000–1,500 ft² (2 bed/1 bath)	$3,500–$6,000	$6,000–$10,000
1,500–2,500 ft² (3 bed/2 bath)	$5,000–$9,000	$9,000–$16,000
2,500–3,500 ft² (4 bed/3 bath)	$8,000–$13,000	$14,000–$22,000
3,500–5,000 ft² (large home)	$11,000–$20,000	$20,000–$35,000

Add $500–$1,500 for drywall patching (typically excluded from plumber quote).

What Drives Cost Beyond Square Footage

Slab foundation vs. crawl space/basement: Slab requires saw-cutting ($500–$2,000 extra)
Number of stories: Multi-story homes need more pipe runs
Galvanized vs. copper original pipes: Galvanized is harder to remove cleanly
Water heater relocation: Add $500–$1,500 if moving the unit
Permit and inspection: Typically $200–$600 depending on jurisdiction
