The cost to repipe a house in Houston ranges from $3,910 to $14,660, with most homeowners paying around $7,330. Your actual cost depends on several factors specific to your home and the Houston-The Woodlands 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 South generally offers lower labor costs, though fast-growing metro areas are seeing rates climb. Year-round building seasons mean more consistent pricing and availability.
Budget $98–$490 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.
UV-resistant PEX and proper insulation for hot water lines are important. Tankless water heaters perform exceptionally well in warm climates due to higher incoming water temperatures.
This project requires a licensed professional in Houston. Attempting whole house repiping without proper licensing can void insurance and create serious safety hazards.

Most whole house repiping projects in Houston take 3–7 days to complete. The timeline depends on project scope, contractor availability in the Houston-The Woodlands metro area, and seasonal demand. Scheduling during Houston's off-peak season (typically late fall through early spring) can reduce wait times and may lower costs.
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.
