Dallas Repiping Cost Estimator

Whole-house repipe of a one-story house

These answers sit in the middle: some factors keep the job simple and some add work. We would most likely run the new lines overhead through the attic and drop them down interior walls to each fixture, capping the old lines in and under the slab and leaving them in place, so the slab itself is not broken.

What a job like this costs

Our typical range for a whole-house PEX repipe in Dallas is $4,500 to $15,000 and up.

Our typical range for a whole-house copper repipe in Dallas is $8,500 to $18,000 and up.

A second story, three or more bathrooms, plaster or tile in the path, a slab route and the patch, texture and paint work all push a house toward the top of the range or past it. These are planning figures, not a quote: we set your number after the first visit, and the written estimate lists the fixtures, route, openings and finish work it covers.

What your project probably includes

• New hot and cold distribution lines to the kitchen, laundry, hose bibbs and two bathrooms
• New fixture stops and stub-outs at each fixture, with escutcheons where the pipe leaves the wall
• Hot and cold connections at the water heater in the garage
• A connection to the main shutoff where the water enters the house
• Pipe support, insulation and freeze protection for lines in the attic, which runs very hot in Dallas summers and can freeze in a hard winter
• Access openings at fittings and turns, with firestopping where lines pass through framing
• A pressure test before walls close and a flush after the new lines are connected
• A City of Dallas plumbing permit, with a rough-in inspection while walls are open and a final inspection
• Patching of the access openings to the level the written estimate defines

Pushing toward the simpler end

• One story. Every fixture is reached from the same attic or crawlspace, so runs are short and each drop is a single wall cavity.
• Slab with attic access. An attic route avoids breaking the slab. The old under-slab lines are capped and abandoned, and the new ones drop through interior walls.
• Drywall. We cut openings in clean rectangles and patch them, and the written estimate says how far the texture match goes.
• Water heater in the garage. Open framing and room to work make the hot and cold connections straightforward.

Pushing toward the larger end

• Material not known yet. On the first visit we identify the pipe at the water heater, under sinks and at the main shutoff before we set a scope.
• Whole house. Every fixture group, the water heater connections and the main shutoff connection are in scope.
• Living there during the work. We stage the work so water comes back on between steps where the plan allows, and openings are protected each day. That adds time.

City of Dallas fee items that can apply

Repiping is permitted plumbing work in Dallas, applied for through DallasNow. The City's development services fee schedule lists these items that can apply. They are parts of the permit cost, not the permit total.

• The base permit fee depends on the permit type the City assigns, so this tool does not add up a permit total. Your written estimate shows the permit as its own line.
• Since June 1, 2026 the City coordinates plumbing rough-in and final inspections. Walls stay open until the rough-in inspection passes, which is how the concealment fee is avoided.

Labor context

Bureau of Labor Statistics wage data for May 2025 puts the mean wage for plumbers, pipefitters and steamfitters at $29.94 an hour in Dallas-Fort Worth-Arlington, against $34.70 for the U.S. A wage is not a billing rate: the rate on an estimate also carries licensing, insurance, vehicles, permits and overhead.

What your written estimate should list

• Which fixtures and branches are replaced, and every place where old pipe stays in service
• The pipe material and type (for example PEX-A or PEX-B to ASTM F876/F877, or Type L or M copper) and the fitting method
• The route, and the number and location of access openings
• Who patches, textures and paints the openings, and to what finish
• Who pulls the City of Dallas permit and books the rough-in and final inspections
• The pressure test before walls close and the flush after connection
• Water-off windows and working days
• The water heater connections, and any valves, as separate lines
• The written warranty: who gives it, what it covers and for how long
• How attic lines are supported, insulated and protected from freezing
• How the home stays usable between stages

Not part of a repipe

• Sewer and drain piping
• Gas piping
• The underground water service line from the meter to the house
• Replacing the water heater itself, and new fixtures
