Leak Detection & Repair

Find it fast. Fix it once.

Hidden leaks quietly damage drywall, flooring, and framing, and feed mold. Pro Gen Plumbing tracks leaks to their source — supply lines, drain lines, shut-off valves, fixture connections, or pipe joints inside walls and ceilings — and repairs them properly.

We explain what we found and why it happened, then give you a clear price before any repair work starts.

Signs you may have a hidden leak

  • Water stains or bubbling paint on ceilings or walls
  • A musty smell, or mold appearing in one spot
  • Unexplained increase in your water bill
  • Low water pressure at one or more fixtures
  • Warm spots on the floor (hot water line) or a water meter that moves when nothing is running
  • Dripping sounds inside a wall

  • Leaking or seized shut-off valves under sinks and toilets

Our process

  1. Inspection. We trace the water back to its source rather than guessing from where it shows up.
  2. Minimal opening. If we need to open a wall or ceiling, we keep the cut as small as possible.
  3. Clear quote. You get the price and the plan before we start.
  4. Repair and test. We fix the leak, run the system, and confirm it's dry.
  5. Finish. Need the drywall patched? We can arrange a finisher so you're not left with a hole.

Frequently asked questions

We're plumbers first, but we work with drywall installers and can arrange the patch so the job is finished end to end.

By reading the evidence — where water shows, which fixtures are nearby, pressure tests, and opening the smallest section possible in the right place.

Yes. A small drip inside a wall can rot framing and grow mold over months. It's much cheaper to fix early.
