Not all plumbing leaks make themselves obvious. Some leaks create visible puddles, but many others hide quietly behind walls, under floors, or even inside the slab foundation. These slow, concealed leaks can waste hundreds of gallons of water, weaken structural materials, encourage mold growth, and lead to costly repairs if ignored. The sooner you recognize the signs, the easier — and more affordable — the fix will be.
Common Signs a Hidden Leak Might Be Lurking in Your Home
✔ You hear running water when no fixtures are on
If faucets are off and toilets aren’t filling, the sound of flowing water often means a leak behind a wall or under the slab.
✔ Your water bill suddenly increases
A spike in usage with no lifestyle changes is one of the most reliable indicators of an unseen leak.
✔ Soft spots, warping, or discoloration on walls or floors
Water trapped behind drywall or flooring causes swelling, sagging, or staining — all warning signs of a leak inside the structure.
✔ Persistent musty or mildew odors
Moisture takes time to become visible, but odors appear much sooner. A smell you can’t track down is a red flag for hidden moisture.
Hidden leaks never resolve on their own, and waiting can allow minor damage to turn into significant structural problems. Gary uses professional leak-detection tools and years of hands-on experience to find the source quickly and accurately — helping you avoid unnecessary damage and high repair costs.
