What’s Causing That Wet Spot? Quick Leak Checks That Save You Money
Introduction
A mysterious wet spot on your wall, ceiling, or floor can be easy to ignore—until it turns into mould, damaged plaster, or a nasty water bill. Hidden leaks are one of the most common plumbing issues Australian homes face, especially in older properties. Understanding the basics of Leak Detection can help you act early and avoid costly repairs.
This guide breaks down what causes wet spots, how to check for leaks quickly, and when it’s time to call in the professionals.
Common Causes of Wet Spots in Homes
Wet patches don’t appear without reason. Some of the most common causes include:
- Leaking pipes behind walls or under floors
- Cracked or damaged plumbing joints
- Roof leaks from broken tiles or flashing
- Blocked or damaged drains causing water to back up
- Faulty appliances like dishwashers or washing machines
In coastal areas and suburbs with older pipework, leaks can develop slowly and remain hidden for months.
Quick Leak Checks You Can Do Yourself
Before calling a plumber, there are a few simple checks you can try:
1. Monitor Your Water Meter
Turn off all taps and water-using appliances. If the meter continues to move, there’s likely a hidden leak.
2. Check for Damp Smells and Mould
Musty odours, bubbling paint, or mould growth often indicate moisture behind walls.
3. Inspect Visible Pipes
Look under sinks, around hot water systems, and behind toilets for corrosion, moisture, or drips.
4. Watch Your Water Bill
A sudden increase without higher usage is a strong sign that Leak Detection is needed.
These checks won’t always locate the exact source, but they help confirm whether a leak exists.
