How Much Does It Cost to Repipe a House in Houston?
Repiping a house costs about $7,500 on average, based on national data from Angi and HomeAdvisor. Most full repipes fall between $1,500 and $15,000, and your home’s size and pipe choice set where you land. Houston adds one more factor. Many homes here still run on galvanized steel pipe from before 1970, and that pipe is at the end of its life.
How much does it cost to repipe a house in Houston?
Angi reports most homeowners pay around $7,500 to repipe a house, with projects running $1,500 to $15,000. HomeAdvisor prices new plumbing at about $4.50 per square foot. That comes to about $6,750 for a 1,500 square foot home and about $9,000 for 2,000 square feet.
Pipe material moves the number a lot. Angi’s example for a two bathroom home runs $4,000 to $6,000 in PEX and $8,000 to $10,000 in copper. These are national figures, not our prices. The only real number for your house comes from a walkthrough and a written estimate.

What makes a repipe cost more or less?
Size and fixture count matter most. Every sink, tub, toilet, and washer hookup needs its own supply lines, so more fixtures mean more pipe and labor.
A second story raises the price. Upstairs bathrooms need longer runs and more openings in walls and ceilings.
Your foundation matters too. Most Houston homes sit on a slab, so new lines route through the attic and down the walls. Pier-and-beam homes have a crawl space, which can make runs easier to reach.
Pipe choice is the last big lever. PEX costs less and bends around framing, so crews cut fewer holes. Copper costs more per foot and takes more time to fit and solder. Wall and ceiling repair sits on top of all of it, and many plumbing bids leave that part out.
Why do older Houston homes need a repipe?
Galvanized steel was the standard water pipe in American homes built before about 1970. Plumbing guides put its working life at 40 to 60 years. A house built in 1965 is past that window today. Houston neighborhoods like Oak Forest and Meyerland went up in those years, so the problem is common here.
Galvanized pipe fails from the inside out. The zinc coating wears away, and rust builds up until the water path narrows. Pressure drops and water runs brown after a trip away. Then pinhole leaks start. Once one leak appears, the rest of the system is the same age and condition.
What does a whole-house repipe include?
A full repipe replaces every hot and cold water line in the house. New lines run from the main shutoff to each fixture. You also get new shutoff valves at the fixtures and fresh connections at the water heater. The new system gets pressure tested, and the city inspects it. A standard repipe covers the water supply lines only, so drain and sewer pipes are a separate job.
A repipe also opens walls and ceilings in most rooms with plumbing. Plumbing-only companies run the pipe and leave the patching to someone else. Then you must find a drywall crew and a painter to finish your own house. We are a remodeling contractor with master plumbers on the team. After the pipe work, we patch, float, texture, and paint the same walls.
How long does a repipe take?
Bob Vila puts a whole-house repipe at a few days to a few weeks. Most single story homes need a few days of pipe work. Two story homes and high fixture counts take longer.
You can stay in the house during the job. Water goes off in stretches and comes back on before the crew leaves most days. Wall repair and paint add more days after the plumbing passes inspection. Permit and inspection scheduling can add a day or two to the calendar.
Do you need a permit to repipe a house in Houston?
Yes. The Houston Permitting Center requires a plumbing permit for this work. A city plumbing inspector must approve the job before it is finalized. Your contractor pulls the permit and schedules the inspection. HomeAdvisor puts typical permit fees at $50 to $500.
The permit protects you. Unpermitted plumbing work can stall a home sale when the buyer’s inspector finds it. The city inspection also checks the pressure test and the quality of the connections.
Should you repipe or keep fixing leaks one at a time?
Fix single leaks when the system is sound. A newer copper or PEX system with one bad fitting does not need a repipe.
Rusted galvanized pipe is a different case. Patch one pinhole and the next one opens somewhere else, because the whole system wore out together. Each leak call means a plumber bill plus a hole cut in your drywall. Then you pay again to patch and paint it. Leaks inside walls also feed mold and ruin insulation and flooring between visits.
Ask your plumber one question: does the pipe show heavy rust at every cut? If the answer is yes, stop patching and price the full repipe.
