You can safely fix a very small, accessible water leak yourself, but hidden or pressurized-line leaks should be handled by a licensed plumber. The most common DIY-safe issues are loose supply connections or worn faucet washers, while leaks inside walls, slabs, or main lines can spread fast and get expensive. If a supply nut still weeps after a gentle snug, stop—overtightening can split the fitting. In the Portland area, our team can locate hidden leaks without unnecessary demolition and repair anything from fixture drips to slab leaks.
Call a professional promptly if you notice:
- Warm or damp floor spots, bubbling paint, or ceiling stains
- Hissing water sounds with no fixtures running, or a water meter spinning when valves are off
- Water seeping from a slab, foundation, or yard with no visible source
- Corroded or crumbling piping, or a patch that failed again
Shut off the nearest supply valve (or the main) before any work and avoid using nearby electrical outlets until the area is dry.
