    Hidden Water Leaks: Warning Signs Every Homeowner Should Know

    The most expensive leaks are the ones you can't see. A slab leak under your floors or a supply line seeping inside a wall can run for months — inflating your water bill, feeding mold, and weakening the structure of your home — before anyone notices a drop.

    Watch for these warning signs: an unexplained spike in your water bill, the sound of running water when every fixture is off, warm spots on the floor, musty odors, discolored or bubbling drywall, and condensation around baseboards. Any one of these deserves a professional look.

    Here's an easy test: note your water meter reading, avoid using any water for two hours, then check it again. If the reading moved, water is escaping somewhere — and it's time to call a plumber who can pinpoint the leak without tearing open your walls on guesswork.

    Our leak detection service locates leaks behind walls, under slabs, and in yards using pressure testing and moisture mapping — minimal disturbance, maximum accuracy. Once we find it, we explain the repair in plain English and fix it right. If you suspect a leak in your Austin, Round Rock, or Cedar Park home, reach out for a free on-site estimate.
