The cost to repipe a house in Troy ranges from $4,010 to $15,030, with most homeowners paying around $7,510. Your actual cost depends on several factors specific to your home and the Detroit-Warren market.
PEX is significantly cheaper and faster to install than copper, but copper has a longer track record and is required by some local codes.
Larger homes need more pipe, more fittings, and more labor hours — repiping a 2,500 sq ft home costs roughly twice what a 1,200 sq ft home costs.
More bathrooms, kitchens, and fixtures mean more connection points and branch lines, increasing materials and labor.
Slab foundations require rerouting pipes through the attic or walls (expensive) versus crawlspace access which is much easier and cheaper.
Open walls (during a remodel) make repiping dramatically cheaper than working through finished walls, which require cutting and patching.
The Midwest has a strong pool of skilled tradespeople, and labor rates tend to be moderate compared to coastal cities. Union and non-union shops both compete, giving homeowners options on pricing.
Budget $102–$510 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.
Freeze protection is critical here. Budget for pipe insulation, heat tape on exposed runs, and deeper trenching below the frost line. Winter plumbing work typically costs more due to frozen ground conditions.
This project requires a licensed professional in Troy. Attempting whole house repiping without proper licensing can void insurance and create serious safety hazards.

Signs include recurring leaks, rusty or discolored water, low water pressure in multiple fixtures, visible corrosion on pipes, or galvanized steel pipes (common in pre-1970 homes). A plumber can inspect and advise for $150–$300.
PEX is the most popular choice for repiping due to lower cost, faster installation, freeze resistance, and flexibility. Copper is more durable and has a proven 50+ year lifespan but costs 2–3x more installed. Both are excellent choices.
