To find a hidden water leak in a wall or ceiling, watch for moisture clues, isolate fixtures, and verify with your water meter. The most common cause is a slow pipe or fitting leak that wicks through drywall. Pros use advanced locating to target the source and limit opening walls. We offer non-invasive locating and hydro excavation when needed, and we handle this around the Portland metro, including near Hillsboro. Emergency help is available 24/7 for active leaks.
- New stains, bubbling paint, or warped drywall/trim
- Hissing or dripping with all fixtures off
- Meter test: no water running, meter still moves
- Toilet check: dye in tank shows a flapper leak
If a ceiling sags or water is visibly running, shut off the main valve and avoid the area until a pro inspects.
