1930s through 1960s houses

Alamo Heights, Olmos Park and the streets north of Loop 410’s inner stretch were built from the 1930s into the 1960s. Houses are a mix of raised and slab. Those on slabs often have copper that has been repaired or partly replaced over the decades, so what is under the floor can be a mix of original and later work.

Mature trees and thin soil

Large live oaks and pecans stand close to many houses. Soil over limestone is thin in places, and roots reach along the rock. They draw moisture unevenly from the soil near a slab, which adds to movement around it. See slab leaks and expansive clay.

Warm Spot on the Floor? Call Now

Say where it is and how long it has been warm.

Mature gardens and irrigation

North central lots have mature gardens with irrigation systems that may be decades old. Irrigation leaks move the meter like a slab leak, and old systems often have underground valves in boxes that fill with water. A technician rules irrigation out first by closing its supply valve and watching the meter.

This site does not repair irrigation. If the leak is there, an irrigation contractor handles it.

Second leaks

Houses with older copper often have a second leak. After that, 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.

Finished floors and repair choices

Hardwood, tile and stone floors make rerouting a common conversation because it can avoid opening the floor. It depends on attic access and where the leak is.

More about slab leaks in Alamo Heights & North Central

Houses in Alamo Heights & North Central 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.

In Alamo Heights & North Central, this does not mean every house will leak. It does mean that slow leaks are sometimes found where lines bend, change direction or pass through the slab edge, because those places take the most strain.

In Alamo Heights & North Central, minerals in the water can add to the wear over time, though they are one factor among several and no reason to assume a house will leak. What a technician looks at is the pattern: a single leak, several leaks close together, or leaks on different lines.

In Alamo Heights & North Central, water that escapes under a slab on rock can travel along the rock surface before it shows itself, so the damp area may sit some distance from the actual leak. This is why a technician confirms the location with testing rather than trusting where the water appears.

When you call from Alamo Heights & North Central, mention how long you have noticed the signs and whether they change with the weather. Those details help a local crew plan the first test.
