Quick answer
Southdown's housing age points mostly to slab leaks on aging copper supply lines, toilets and shower valves from the original build, and remodel work that exposes old pipe. Today is fine: we answer 24/7, and a leak call opens with a meter reading and isolation of the hot and cold lines before any talk of cutting concrete.
What plumbing calls look like in Southdown
Southdown's median house was built in 1994, a year that sits in the middle of the copper-under-slab era for this part of Texas. Water comes in through a main line from the meter, then branches under the concrete to each bathroom and the kitchen. Drains are plastic. Thirty years of hot water, pressure swings and ground movement wear on that copper in places nobody can see.
Locating a leak under concrete is a step of its own. First comes a meter reading with everything off, then we shut the hot and cold sides separately to see which one is losing water. Listening gear and thermal imaging then narrow it to a small patch of floor. With the spot marked, we price a spot repair and a reroute side by side, and for a second or third leak, a full repipe too.
Pearland calls, Southdown included, are run from our service office in Rosharon, with the phone answered around the clock. If a kitchen or bath remodel is already on your list, we can time a repipe to line up with it, so walls are only opened once and the new lines land where the new fixtures will sit.

Local conditions
HAR counts 1,496 single-family properties in Southdown with a median build year of 1994, which makes it one of the larger 1990s neighborhoods in Pearland. Thirty-year-old plumbing tends to show its age in predictable places: pinhole leaks in copper, water heaters on their second or third replacement, worn shower valves behind original tile, and drain lines slowed by years of buildup. When one of those fails, it is worth asking what else in the house shares the same age.

- Leak DetectionPinpointing a leak under concrete before cutting keeps the opening small and tells you whether the hot or cold side is failing.
- Whole-House RepipingAfter repeat leaks on 1990s copper, moving the supply lines overhead in PEX takes them out of the shifting soil for good.
- Toilet RepairOriginal fill valves, flappers and wax seals wear out on a cycle, and a toilet that runs at night is easy to mistake for a slab leak on the meter.
- Kitchen & Bath Remodel PlumbingA kitchen or bath remodel opens walls anyway, which makes it the cheapest moment to replace old supply lines, valves and drain connections in that room.
- Water Line Repair & ReplacementThe main line from the meter to the house also sits in moving clay, and a leak there shows as a soggy patch in the yard rather than a warm floor.
- Smart Water Shutoff InstallationAn automatic shut-off valve on the main can close the supply when it senses a leak, which limits damage if a pipe fails while you are away.

Close every faucet and shut off appliances and the ice maker, then watch the meter's small leak indicator for a few minutes. If it moves, water is going somewhere. Our meter reading guide shows what to look for on common meters.
On the meter, it can look identical. Before calling a slab leak, put a few drops of food coloring in each toilet tank. Color in the bowl without flushing means a leaking flapper, which is a much smaller repair.
For a first leak on pipe that otherwise looks sound, a spot repair or single-line reroute usually wins. Once leaks repeat, each new repair adds floor work and risk, and a repipe becomes the better long-term spend.
Only the affected line needs to be off while we work. In many cases we can isolate it and keep the rest of the house running. For a full repipe, we plan the switchover so water is usually back on by evening.
