Repiping projects are a significant revenue driver for plumbing businesses, but pricing them incorrectly kills margins while overpricing loses jobs. Understanding how to break down labor costs, material expenses, and overhead will give you confidence in quoting and help you compete effectively in your market.
Material Costs: The Foundation of Your Estimate
Material pricing varies dramatically depending on pipe type and local supplier relationships. Copper runs $0.80–$1.50 per linear foot for 1/2" diameter, while PEX (cross-linked polyethylene) costs $0.15–$0.35 per foot and PVC ranges from $0.30–$0.70 per foot. Larger diameter pipes scale up proportionally—2" copper can hit $3.00+ per foot.
Beyond the pipe itself, factor in fittings, connectors, sealant, flux, and hangers. These ancillary materials typically add 15–25% to your base pipe cost. Get quotes from at least two suppliers and negotiate volume discounts; many plumbing wholesalers offer tiered pricing that makes a real difference on larger jobs.
Don't forget to include waste. Plan for 5–10% material overage depending on job complexity and existing wall conditions. A straightforward apartment repiping might stay at 5%; a Victorian home with multiple turns and obstacles justifies 10%.
Labor Calculation: Time + Hourly Rate
Labor is where most contractors leave money on the table. Start with your fully-loaded hourly rate—this includes wages, payroll taxes, workers' compensation, vehicles, tools, and overhead. Most repiping contractors operate at $85–$150 per hour depending on location, experience, and market positioning. High-cost metros like San Francisco or New York can justify $175+.
Next, estimate the time required. A standard single-bathroom repiping in a smaller home typically takes 8–16 hours for a crew of one or two. A full house repiping in a 2,000 sq ft home (3–4 bathrooms, kitchen, main lines) realistically takes 40–80 labor hours depending on access, pipe material choice, and whether you're working around occupied tenants.
Create a simple formula:
- Measure total linear feet of pipe replacement
- Divide by your crew's production rate (typically 10–20 linear feet per hour for installation)
- Multiply by hourly rate
- Add 10–20% for inspection, pressure testing, and cleanup
Hidden Costs That Erode Profit
Most repiping jobs involve wall or ceiling penetration. Budget for drywall repair and patch—this adds $200–$800 depending on extent. If you're not doing the finishing work, subcontract it out and include that cost in your quote.
Permits and inspections are mandatory in most jurisdictions. Permit costs range from $75–$300, plus inspector time (typically $150–$400). Pass these through directly to the customer or absorb them in a slightly higher labor rate if you want to include them in your quote.
Pressure testing and flushing add 2–4 hours to the timeline. Old debris in lines sometimes requires multiple flushes. Include contingency time for this in your estimates, especially on properties with existing galvanized or cast-iron lines.
Practical Pricing Example
A 1,500 sq ft, single-story house needing full repiping with PEX:
- Materials: 350 linear feet PEX @ $0.25/ft = $87.50, plus $120 in fittings and hardware = $207.50 + 10% waste buffer = $228
- Labor: 350 linear feet ÷ 15 ft/hour = 23.3 hours + 6 hours inspection/testing/cleanup = 29.3 hours × $110/hr = $3,223
- Permits & inspection: $250
- Drywall repair: $400
- Total cost to you: $4,101
- Markup (35%): Add $1,435
- Customer quote: $5,536
Adjust the markup percentage based on your market, competition, and project complexity. High-difficulty jobs (tight spaces, asbestos abatement, commercial buildings) warrant 40–50% markups.

Accurate pricing means nothing if customers can't find you. Listing your repiping and pipe installation services on Mercoly connects you directly with homeowners and property managers actively searching for these services—helping you win more leads and fill your pipeline consistently.
Frequently Asked Questions
Q: Should I charge differently for copper versus PEX? Yes—copper labor is slower due to soldering, so account for roughly 15–20% longer installation time, which justifies a higher labor rate even if material costs are higher.
Q: How do I price repiping in occupied apartments or homes? Add 20–40% to labor estimates; tenant access restrictions, noise considerations, and working around occupied spaces slow crews significantly.
Q: What's a realistic profit margin for repiping work? A healthy repiping business targets 30–40% gross margin after all direct costs (materials, labor, permits), which gives you room for overhead, marketing, and contingencies.
