Plano built much of its housing between 1970 and 1995, right through the years when galvanized steel, early copper and gray polybutylene were going into walls and slabs. If you're seeing pinhole leaks, rusty water or low pressure, we replace the supply lines with PEX at a published price per fixture.

Two different jobs: the repipe and the yard water line
- Repipe: the hot and cold supply lines inside your house, from the main shutoff to every fixture. This is what fails with pinhole leaks, rust and low pressure.
- Water line (service line): the pipe in your yard from the City meter to the house. The City of Plano owns the line from the main to the meter; from the meter to your house is yours.
We do both, and we’ll tell you honestly whether you need one, the other, or both.
What’s in Plano walls, by decade
These are typical patterns, not guarantees; we confirm on site.
- 1950s–1960s (Old Towne, Haggard Addition, Belle View Estates, Briarwood): galvanized steel or early copper. Galvanized rusts from the inside and chokes the flow.
- 1970s–early 1980s (Dallas North Estates, Park Forest, Los Rios): mostly copper in or under the slab. Copper can pinhole, and under-slab copper is a common source of slab leaks.
- About 1978–1995: polybutylene, the gray plastic pipe, shows up in some North Texas homes from this window. Its fittings are a known failure point, and many insurers and buyers ask about it.
Plano has inventoried more than 81,000 water service lines for federal lead and copper rules; you can look up the recorded material for your address on the City’s service line map.
Signs your Plano home needs a repipe
A second or third slab leak or pinhole leak in a few years

Gray plastic pipe (polybutylene) at the water heater or under sinks
You're selling, and the inspector flagged the supply piping
Your insurer is asking about pipe material
How a PEX repipe works
- Walk-through and drop count. We count every fixture drop and decide the route: through the attic and down the walls (most slab homes) or under the floor (pier and beam). This reroute usually means we abandon the old lines in the slab instead of digging them out.
- Fixed written price. Drops × your foundation rate. No hourly billing.
- New PEX to every fixture. All replacements use PEX piping, with new shutoffs at each fixture.
- Pressure test, then patch. We test the system before we close any walls, and patch the access openings. The written quote will say whether texture and paint are included.
- Permit and inspection where the City requires one. We pull the permit and meet the inspector.
Most homes keep water service overnight during the job. We’ll give you the schedule with the written quote.
Replacing the yard water line
If your leak is between the meter and the house (a soggy spot in the yard, a meter that spins with everything off, or low pressure throughout), the fix is a new PEX service line from the meter to the house shutoff, with a new shutoff valve. A typical yard water line replacement from the meter to the house runs $3,500–$4,500, confirmed in a written quote after we see the run. We install PEX, with a new shutoff valve you can actually reach.
Repipe cost in Plano: priced per drop
A drop is one supply connection to a fixture. We price repipes per drop, so you can count your own house and know the number before we arrive.
Example (illustration only): a 1980s Plano slab home with 2 full baths, 1 half bath, 2 hose faucets, and a kitchen sink, dishwasher, washer, water heater and ice maker line: 10 + 3 + 2 + 5 = 20 drops × $1,050 = $21,000, or $17,850 with same-day approval.

Plano repipe and water line FAQs
How much does a whole-house repipe cost in Plano?
We price per fixture drop: $1,050 per drop on a slab and $500 per drop on pier and beam. A typical 2.5-bath slab home is about 20 drops, or $21,000 before the 15% same-day discount.
What is a drop?
One water supply connection to a fixture. A full bath counts as 5 drops, a half bath as 3, each hose faucet as 1, and appliances like the dishwasher, washer and water heater as 1 each.
Why does a slab repipe cost more than pier and beam?
On a slab we can't run new pipe under the floor, so we reroute through the attic and walls, which means more access, more pipe and more patching.
Who owns the water line in Plano?
The City owns the line from the main up to the meter. The line from the meter to your house, and all the plumbing inside, belongs to the homeowner.
Do you use PEX or copper?
All of our repipes use PEX. It handles North Texas freezes better than rigid pipe, has fewer joints in the walls, and costs less to install.
I have polybutylene. Do I have to replace it?
Nothing requires it, but polybutylene fittings are a known failure point and some insurers and buyers object to it. A repipe removes the question.
How long does a repipe take?
Water is usually back on each night. We'll give you the job schedule with the written quote.
