Whole-house repipe cost in Dallas

Quick answer

Published Dallas estimates put a whole-house repipe at roughly $4,950–$12,100 in PEX and $8,800–$19,800 in copper, with partial repipes around $1,650–$4,950. These are published estimates, not a guaranteed price; home size, bathroom count, stories and wall access move your total most.

Many Dallas homes sit on slabs, so repipes are usually rerouted through the attic and walls instead of under the slab. Local plumbers note copper typically runs about 30–40% more than PEX for the same layout. This is educational information, not plumbing or legal advice; Texas requires a licensed plumber and the city permit rules for your address control your project.

What most people miss

Ask whether drywall repair is in the price

The biggest gap between repipe quotes is often who patches the walls and ceilings. Some plumbers include patch-and-texture, some leave rough openings for you to hire a drywall contractor, and few include paint. Get it in writing.

How this price is built

Pipe material and fixtures

PEX-A, PEX-B, CPVC or Type L copper, number of fixtures reconnected, new shutoff valves and whether a new main shutoff or pressure-reducing valve is included.

Routing

Slab homes are usually rerouted overhead through the attic. Ask how attic lines are insulated against Texas freezes and protected from summer heat.

Wall access and patching

Number of openings, patch and texture, and whether paint is included or excluded.

Permit and inspection

A City of Dallas plumbing permit and inspection by a Texas-licensed plumber (TSBPE). Confirm the fee is in the quote.

Old pipe issues

Polybutylene (common in homes from about 1978–1995) and corroded galvanized steel are common reasons for a repipe. Removing or abandoning old pipe should be described.

What makes a quote high

Copper pushed without reason
Copper is a legitimate choice but costs more. Ask the plumber to price both so you can decide.
Slab leak used to sell a full repipe
One slab leak does not always mean the whole system has failed. Ask for the leak location and pipe condition evidence.
Unpriced drywall
A low plumbing price can become expensive once you hire separate drywall and paint work.
Missing permit
Unpermitted repipes can cause problems at sale or with an insurance claim. Ask for the permit number.

Itemised versus vague

A quote you can evaluate looks different from one you can't. This is what to look for, line by line.

Item	A quote you can judge	A quote you can't
Material	PEX type or copper type named	New pipes
Scope	Fixtures, valves and main shutoff listed	Whole house
Walls	Patch, texture and paint terms stated	Minimal holes
Permit	City permit and inspection included	Not required
Warranty	Labour and material terms in writing	Lifetime warranty

Questions to ask before you approve

Can you price both PEX and copper for the same layout?
How many wall and ceiling openings, and who patches and textures them?
How will attic lines be insulated?
Who pulls the City of Dallas plumbing permit?
What is your workmanship warranty, and is the manufacturer warranty registered?

Message to a Dallas repipe plumber

Copy these lines as they are. Politeness plus specifics gets answers.

1.“Please price PEX and copper separately for the same layout.”
2.“List fixtures, valves and the main shutoff included.”
3.“State how many openings you make and who patches, textures and paints them.”
4.“Include the city permit, inspection and your warranty terms.”

When a high price is legitimate

A higher-than-expected price isn't automatically a bad one. These are the situations where it's usually justified.

Two-story homes and extra bathrooms add pipe, fittings and labour.
Copper materials cost more than PEX.
Finished ceilings and tile walls make access slower.
Replacing polybutylene or galvanized lines can reveal other code updates.
