We've been fixing plumbing in Georgetown since the 1990s. Homes on the west side of town in Wolf Ranch and Cimarron Hills sit on limestone bedrock. That rock drains surface water great, but tree roots break into sewer lines hunting for moisture. We replace a lot of old clay pipes in these neighborhoods because roots find every crack.
The east side in Sun City and Georgetown Village has clay soil that swells when it rains and shrinks when it's dry. Your foundation moves slightly with those changes, and plumbing connections take the stress. Joints develop leaks during summer when the ground contracts.
Berry Creek and Gabriel's Grove were built in the 1980s and 1990s. Most homes still have original galvanized steel pipes that are corroding from the inside. Low pressure and rusty water mean it's time to replace them, and we do that work constantly in these older neighborhoods.
Your water comes from Lake Georgetown. It's hard water with high mineral content. Water heaters need flushing more often than they would with softer water. Faucet aerators clog faster. Without a water softener, you're constantly fighting mineral buildup that shortens fixture life.
