How to Know If You Have a Water Leak: 7 Warning Signs Homeowners Shouldn’t Ignore

Water leaks can cause thousands of dollars in damage before you even realize there’s a problem. Whether it’s a slow drip behind the walls or a burst pipe underground, early detection is the key to avoiding costly repairs.

In this post, we’ll show you the most common signs of hidden water leaks and explain when to call a professional leak detection specialist in Melbourne.


🔍 Why Water Leak Detection Matters

Water leaks don’t just waste water—they cause mould growth, property damage, and skyrocketing water bills. If you suspect a leak but don’t see visible signs, it might be hidden behind walls, under concrete, or in underground pipes.

That’s where non-invasive leak detection comes in.


✅ 7 Signs You Might Have a Water Leak


1. 💧 Unexpectedly High Water Bills

If your water usage hasn’t changed but your bill keeps rising, you could be losing water through an undetected leak.


2. 🧱 Damp or Discoloured Walls

Brown or yellow stains on walls or ceilings often mean water is seeping from a hidden pipe. Don’t ignore the signs—this can quickly lead to structural damage and mould.


3. 🔇 Hissing or Dripping Sounds

Hear dripping or running water when no taps are on? It’s a classic sign of a leaking pipe inside the walls or under the floor.


4. 🦠 Mould or Musty Smells

Unexplained mould patches or a persistent musty smell in your bathroom, laundry, or hallway? That’s often due to a slow leak that’s been feeding moisture into your walls or subfloor.


5. 🌿 Greener Patch in the Garden

Got one spot in your lawn that’s greener or constantly wet? It could be a leaking underground pipe, especially in areas near stormwater or sewer lines.


6. 🚿 Shower Always Feels Damp

If your shower area never fully dries or your bathroom tiles feel spongy, you may have a shower leak behind the wall or under the base—a common issue we fix with our leak detection services in Melbourne.


7. 🏚 Cracked Concrete or Foundation Shifts

Leaks under concrete (also called slab leaks) can cause the ground to shift, resulting in cracked driveways, loose tiles, or uneven flooring.
