Slab Leak Repair and Replacement in South & Southwest Austin, TX
Slab leak repair and replacement in South & Southwest Austin starts with finding the leak. South Austin runs from older slab neighborhoods near the river to large newer communities at the edge. The ground changes from clay to rock as you go west.
Answered 24 hours a day, every day.

Clay in the south, rock toward Oak Hill
South of the river and east of the escarpment, ground is clay and moves with moisture. Toward Oak Hill and the southwest, limestone comes close to the surface. Many lots have both clay pockets and rock. Either can wear a line from the outside over time. A technician locates the leak first.
1970s to 1990s neighborhoods and newer communities
Neighborhoods around Southpark Meadows, Oak Hill and South Congress were largely built from the 1970s through the 1990s, and many houses have copper under the slab. Some from the late 1970s to the mid-1990s may have polybutylene. Communities at the edge, such as Circle C and Slaughter Creek, are newer and use PEX. A technician confirms what a given house has.
Tell us how much it changed.
Rental houses and absentee owners
South Austin has many rental houses, and a slab leak in a rental raises questions of access and authority. A tenant who notices a warm spot or a bill increase should tell the owner or manager in writing. The owner or manager decides on repairs, and whoever has authority can call us.
For landlords: a leak that runs for weeks adds to a utility bill and can damage flooring that a tenant is responsible for reporting. See rental and commercial slab leaks for access and scheduling.
Tell us what was repaired before.
Second and third leaks
Houses with older copper often have repeat leaks. After the second, rerouting lines above the slab or repiping may come up. The technician explains the reasoning and none of it is promised. See repeat slab leaks.
A local crew explains what happens next.
First steps at home
Turn off everything that uses water and watch the meter. If it moves, water is escaping somewhere on the property. Irrigation and outdoor taps move it too, so a technician rules those out first.

More about slab leaks in South & Southwest Austin
Houses in South & Southwest Austin with original copper supply lines have had decades of water moving through them, and copper does not wear evenly. It tends to thin in a few places, usually where the water runs hottest, where flow is fastest or where a fitting was soldered. That is how a pinhole can appear in one spot while the rest of the line still looks sound.
Opening a slab over rock is slower and more disruptive than over soft ground. That is one reason a technician in South & Southwest Austin may bring up rerouting a line through the walls or attic as an option, instead of cutting through the floor to reach it.
In South & Southwest Austin, A leak in one fitting does not automatically mean the whole house needs new lines. It does mean the conversation about options is worth having early. A spot repair, a reroute of the affected line and a full repipe each suit different situations, and the technician walks through how many connections are involved and what sits above them.
In South & Southwest Austin, if you notice new cracks in tile or doors that stick, those are separate matters and not proof of a leak. A leak and a foundation concern can appear together or apart, and the way to tell them apart is to test the plumbing first.
Before you call from South & Southwest Austin, jot down which fixtures sit closest to the warm spot, whether the water bill has changed and whether the meter dial moves with everything off. Those three details help a local crew plan the visit.
