How to Tell If You Have a Hidden Water Leak
Silent leaks waste thousands of litres and cause massive structural damage before you even notice them.
Why Hidden Leaks Are Dangerous
Unlike a dripping faucet, hidden leaks operate silently — often behind walls, under slabs, or in crawl spaces. By the time visible damage appears, the problem has often been going on for months.
A small, continuous leak can cause wood rot, mold growth, foundation damage, and elevated water bills that add up to hundreds of dollars annually.
Warning Signs to Watch For
1. Unexplained increase in your water bill
If your water bill has increased without a change in usage habits, a hidden leak is one of the most common culprits.
2. Damp spots on walls, ceilings, or floors
Discoloration, soft spots, or visible dampness without an obvious source is a strong indicator of a leaking pipe nearby.
3. Mold or mildew smell without visible mold
A persistent musty odor — especially in closets or under sinks — can mean moisture is accumulating somewhere hidden.
4. Sound of running water when nothing is on
If you can hear water moving through pipes when all fixtures are off, you may have a leak allowing constant water flow.
5. Low water pressure throughout the home
A significant water leak can reduce pressure throughout your system, making showers weaker and fill times longer.
