Repiping Cost Calculator
Use our free Repiping Cost Calculator to quickly estimate material, labor, and disposal costs for full or partial repipes based on inputs like linear feet of pipe, pipe material (PEX, copper, CPVC), fixture count, and job complexity. Perfect for plumbers, remodelers, and homeowners planning a repipe project.
Repiping Cost Formula
The calculator aggregates length-based material costs and labor estimates, adds fixed line items (permits, water heater work), and applies a contingency factor to produce a planning-level project cost.
How this repiping calculator works
Starting from total pipe length and fixture count, the calculator estimates required pipe and fitting quantities, multiplies by unit prices, and estimates labor from industry-standard installation rates adjusted for job access and complexity. It then adds permit, disposal, and contingency to provide a complete project-level estimate. Use results for budgeting—obtain on-site quotes for final pricing.
When to use this Repiping Cost Calculator
When budgeting a full-house repipe before contractor bids
To estimate costs for converting pipe material (copper → PEX)
When planning partial repipes (kitchen/bathroom wing) or service line replacement
For preliminary homeowner quotes and financing applications
To compare labor vs material cost impacts across materials and access conditions

Typical Repiping Cost Ranges & Benchmarks
Benchmarks vary by region, home layout, access, and material. Use these ranges to sanity-check inputs.
PEX material (pipe only)
Copper material (pipe only)
Fittings & valves

Typical total (full-house, PEX)
Typical total (full-house, copper)
Use local contractor quotes to refine these benchmarks—access, wall/ceiling finishes, and home age are major cost drivers.
Frequently Asked Questions
It gives a planning-level estimate. On-site inspections reveal hidden costs (wall/ceiling repairs, access issues). Always get contractor quotes.
PEX is typically cheaper and faster to install than copper; copper costs more in material and labor but can be chosen for longevity or code preferences.
Most jurisdictions require plumbing permits and inspections for repiping—include permit fees in budgeting.
Hard access (finished walls, ceilings, multi-story homes) increases labor and patch/repair costs significantly—plan for higher labor multipliers in those cases.
Service line replacement (from meter to house) is a separate scope with its own permitting and costs—include as an additional line item if relevant.
Yes—targeted branch replacements are cheaper but may not resolve systemic issues; evaluate based on pipe condition and failure risk.
Add separate allowances for patching and finishing per affected area or ask contractors for combined install + repair quotes.
PEX is widely used in modern repipes but check local code, water chemistry, and compatibility with existing systems (e.g., certain polybutylene issues).
