How Much Does Repiping a House Cost in North Texas?

If your home has recurring pinhole leaks, rusty water, or aging galvanized pipe, at some point a plumber says the word repipe, and your next question is what that costs. Fair. A published DFW benchmark for a whole-house repipe runs roughly $4,500 to $11,000. Treat that as a benchmark, not a quote, because the real number for your house depends on things a benchmark cannot see. Here is what actually drives it.

What you are paying for

A repipe replaces the water supply lines throughout the house, the pipes that carry fresh water to every fixture. It is a bigger job than a single repair because it touches every bathroom, the kitchen, the laundry, and the water heater, and it involves opening and patching some drywall to reach the runs. The price bundles several real costs:

• Labor, the largest share, driven by the size and access of your home
• Pipe material, PEX or copper, and all the fittings and valves
• Drywall access and patching where lines are reached
• Permits and inspection, required for this scope in most cities
• Restoring water service cleanly and pressure-testing the new system

PEX versus copper

The material choice is the biggest lever you control. Both are good pipe, but they behave differently and cost differently.

PEX

PEX is flexible plastic tubing. It is less expensive in both material and labor because it runs in long flexible lengths with fewer fittings and needs less wall opening. It resists the scale buildup that North Texas hard water causes, and it handles a freeze better than rigid pipe because it can expand slightly before bursting, a real advantage after what Winter Storm Uri did to homes across the region in 2021. For most Colleyville repipes, PEX is the practical choice.

Copper

Copper is the traditional rigid metal pipe. It costs more up front, in both material and the labor to sweat all the joints, and it is more vulnerable to bursting in a hard freeze. Some homeowners prefer it for its long track record and because it is unaffected by UV in exposed runs. It is a fine material, it just usually lands at the higher end of the benchmark.

What moves the number

Two homes on the same street can get different repipe quotes for good reasons.

• Home size and number of bathrooms, more fixtures means more pipe and labor
• One story versus two, second-floor runs are harder to reach
• Slab foundation, which is standard here and affects how lines are routed
• Accessibility, an open attic and crawl space are easier than finished, tight spaces
• How much drywall must be opened and patched
• Whether you upgrade shut-off valves, hose bibs, or the water heater connections at the same time

That slab foundation point matters in North Texas. Because so many homes here sit on slab, plumbers often route new lines through the attic and down the walls rather than under the slab, which shapes both the approach and the cost. A good estimate accounts for your specific layout, not a generic average.

How to read a repipe quote

A trustworthy quote is itemized enough that you can see what you are buying. Look for the material specified, the scope of drywall work and who patches it, whether permits and inspection are included, and the warranty on both parts and labor. A suspiciously low headline number often leaves out drywall repair or the permit, which then reappear as change orders. Get the scope in writing.

When a repipe is worth it

Repiping is the right call when the whole system is failing, not just one spot. Repeated pinhole leaks, discolored or metallic-tasting water, visibly corroded galvanized pipe, and dropping pressure across multiple fixtures all point to a system at the end of its life. Patching one leak after another on old pipe is money poured into a losing position. A repipe resets the clock and, in North Texas, is a good moment to move off scale-prone materials.

While the walls are open, many homeowners also address the water heater, since the connections are already exposed, so it is worth asking our water heater repair and installation team to look at yours during the project. For the repipe itself, our whole-house repiping crew gives you an itemized, on-site estimate with the material, drywall scope, permit, and warranty all spelled out, no benchmark guesswork.
