A hidden water leak can be one of a homeowner's worst nightmares. Unlike a dripping faucet, these leaks are often out of sight, silently causing damage to your home's structure and promoting mold growth. Knowing the signs of a hidden leak can help you catch it early and prevent a major disaster.

1. An Unexplained Increase in Your Water Bill

If your water bill has suddenly spiked without a change in your water usage habits, it's a strong indicator of a leak. Keep an eye on your monthly statements and compare them to previous months or the same period last year.

2. Mold or Mildew

Mold and mildew thrive in damp environments. If you notice a musty smell or see mold growth on walls, ceilings, or floors (especially in areas without high humidity like a shower), it could be due to a leak in a nearby pipe.

3. Stains, Discoloration, or Damage

Water stains on your walls or ceilings are a clear sign of a leak. Look for discoloration, bubbling or peeling paint, or warped wallpaper. Don't ignore these signs, even if the area isn't actively wet to the touch.

4. The Sound of Running Water

If you can hear water running when all your faucets and appliances are turned off, you likely have a leak. This could be a hissing sound from a pipe or the sound of dripping inside a wall.

5. A Spinning Water Meter

You can check for a leak by using your water meter. First, make sure all water is turned off in your home. Then, check your water meter. If the dial is spinning, it means water is flowing somewhere on your property, indicating a leak.
