Interactive estimate

Estimate your project cost

Whole-house repiping pricing depends on square footage, number of bathrooms and fixtures, PEX versus copper or CPVC material choices, slab or crawlspace access, old galvanized, polybutylene, lead, or failing CPVC pipe risk, wall openings, drywall repair, paint, permits, water shutoff timing, and whether a partial repipe house scope is enough.

How this estimate should work

  1. Start with current whole-house repiping and replumbing ranges, then scale by home size, bathroom count, fixture count, wet-room spacing, and total pipe runs instead of using one flat per-house average.
  2. Separate PEX-versus-copper, CPVC, premium PEX manifolds, mixed-material systems, shutoff valves, supply branches, and fixture reconnections so material choices are not compared as if they have the same labor and lifespan.
  3. Flag galvanized, polybutylene, lead, or failing CPVC risk, repeated leaks, low pressure, rusty water, pinhole corrosion, and water-pressure and leak history before deciding whether a partial repair is still reasonable.
  4. Price crawlspace, basement, attic, two-story, slab, tile, cabinet, and finished-wall access separately because openings, protection, cleanup, and daily water shutoff coordination can move labor materially.
  5. Track drywall repair and painting, texture matching, permit and inspection fees, disposal, temporary water service, fixture supply lines, water heater tie-ins, and patch allowances as separate bid lines.
  6. Use partial-versus-whole-home repipe guidance when a homeowner is deciding whether isolated fixture repairs, a bathroom remodel rough-in, or a full supply-line replacement is the better long-term quote target.

Cost examples

Lower-scope whole house repiping $3,000 - $18,700

A planning example for smaller or simpler whole house repiping work with easier access, fewer upgrades, and limited prep.

Typical whole house repiping $4,000 - $22,000

A planning example around the starter range when home size, bathroom and fixture count, and pipe material are near the middle of the project.

Higher-scope whole house repiping $4,800 - $29,700

A planning example for larger, upgraded, or harder-to-access whole house repiping work with more site prep or coordination.

Common questions

How much does whole house repiping cost?

A typical whole house repiping planning range is $4,000 - $22,000 per project. Final pricing depends on home size, bathroom and fixture count, pipe material, access and foundation, local labor rates, access, permits, and project conditions.

What changes a whole house repiping estimate the most?

The biggest changes usually come from project scope, especially home size, bathroom and fixture count, pipe material, access and foundation. Contractor availability, code requirements, site access, disposal needs, and regional cost pressure can also move the final quote.

How should I compare whole house repiping bids?

Ask each contractor to price the same scope, materials, timeline, cleanup, warranty, and permit assumptions. Then compare what is included, what is excluded, and how each quote handles surprises.

Compare contractor bids

Often included

  • Labor and standard materials for whole house repiping.
  • Basic site preparation, cleanup, and disposal assumptions.
  • Standard contractor scheduling and project coordination.

May cost extra

  • Changes related to home size, bathroom and fixture count, pipe material, or access and foundation.
  • Permits, code upgrades, access issues, repairs, haul-off, or special-order materials.
  • Scope changes discovered after the contractor inspects the site.

Confirm before hiring

  • Whether the bid is fixed-price, allowance-based, or subject to site conditions.
  • What is excluded, what could trigger a change order, and how surprises are priced.
  • Warranty terms, payment schedule, start date, and cleanup responsibilities.

When to request quotes

Use the estimate after you know home size, bathroom and fixture count, pipe material, and access and foundation well enough to compare the same scope across contractors.

Good time to ask

  • You can describe home size, bathroom and fixture count, pipe material, and access and foundation without guessing.
  • You have photos, measurements, or notes that show the current whole house repiping scope.
  • You are ready to ask at least two contractors for the same included work, exclusions, warranty, and change-order rules.

Wait until you know more

  • The project scope may change after an inspection, repair decision, insurance review, or permit requirement.
  • You are still deciding between whole house repiping options that would create different material, labor, or access needs.
