Repipe a house cost in San Antonio, TX (2026)
The short answer
Repiping a house in San Antonio typically costs about $3,600 to $13,700, with PEX running roughly 30 to 40 percent below copper. The local reason it comes up: the median San Antonio home dates to around 1986, in the polybutylene-pipe era, so aging supply lines and slab-on-grade construction make a full repipe a common call. These are our national repipe figures adjusted for local plumber wages. See how we localize a range.

We did not collect local repipe quotes; San Antonio plumbers rarely publish a whole-house repipe price. These figures are the national cited ranges multiplied by the local wage index, which keeps them honest and consistent with the national picture. Home size, material, and wall access move the number far more than city does.
Why San Antonio costs differ
A few verified local facts explain why repiping comes up here.
- Polybutylene-era housing stock. The median San Antonio home was built around 1986 (Census ACS), which straddles the polybutylene-pipe era of roughly 1978 to 1995. Homes from that window can still have original gray polybutylene or aging supply lines, which is a common reason local plumbers recommend a full repipe rather than another spot repair. [source]
- Slab-on-grade over expansive clay. San Antonio sits on expansive clay soils, and most homes here are built on a slab-on-grade foundation (commonly post-tension), not a basement. That is why slab leaks, where a supply line under the concrete fails, are a recognized local repair and why rerouting overhead is often cheaper than opening the slab. [source]
- Very hard water. SAWS reports typical hardness of 15 to 20 grains per gallon, and mineral-heavy water is hard on aging metal supply lines, which is one reason a full repipe can beat repeated patches. [source]
- Local plumber wages run about 9% below the national median. The San Antonio metro median wage for plumbers is $58,180, versus $63,800 nationally, which trims the labor share of a large job here. [source]

What moves the price
- Pipe material. PEX is typically 30 to 40 percent cheaper installed than copper, so the material choice alone can move the total by thousands.
- Home size and stories. More square footage, more bathrooms, and a second story all add pipe length and labor hours.
- Wall and slab access. Open drywall is quick to work in. Tight spaces, or lines that run through a slab, add time and restoration cost.
- Freeze resistance. PEX tolerates the occasional San Antonio hard freeze better than rigid pipe, which some homeowners factor into the material choice.

Common questions
San Antonio repiping questions
How much does it cost to repipe a house in San Antonio?
A whole-house repipe in San Antonio typically costs about $3,600 to $13,700, with a common 2,000-square-foot home landing near $5,500 to $9,100 in PEX and $7,300 to $13,700 in copper. Drywall repair afterward often adds $900 to $2,700 and is easy to overlook. These are our national repipe figures adjusted for local plumber wages; see our methodology.
Why might a San Antonio home need a repipe?
The median San Antonio home was built around 1986, which straddles the polybutylene-pipe era of roughly 1978 to 1995. Homes from that window can still have original gray polybutylene or aging supply lines that fail repeatedly. Combined with slab-on-grade construction over expansive clay, that makes a full repipe a common recommendation once patches stop holding.
PEX or copper for a San Antonio repipe?
PEX typically costs 30 to 40 percent less installed, resists freezing better, and installs faster with fewer joints, which matters for the occasional hard freeze here. Copper is more rigid with a long track record. Both are code-compliant in San Antonio. Ask your plumber which suits your walls, your water, and your budget.
Do I need a permit to repipe a house in San Antonio?
Yes. A repipe is major plumbing work that requires a City of San Antonio plumbing permit, with the base fee starting around $50 plus surcharges and inspections. Your licensed plumber normally pulls it. Confirm the plumber’s license is current with the Texas State Board of Plumbing Examiners before the job begins.
