Signs You Have a Hidden Water Leak

Not every leak shows up as an obvious puddle on the floor. Hidden leaks - under floors, behind walls, or underground - can go unnoticed for months while quietly causing damage. Here's what to watch for.

Warning signs

• ✓ A water bill that's noticeably higher than usual with no change in habits
• ✓ Damp patches, discolouration, or peeling paint on walls or ceilings
• ✓ A musty smell that won't go away
• ✓ A boiler or heating system that keeps losing pressure
• ✓ The sound of running water when every tap is off
• ✓ Unusually lush or soggy patches on the lawn (for underground supply leaks)

Why it's worth acting quickly

Left long enough, a hidden leak can lead to structural damage, mould growth, and much larger repair bills than catching it early. It's also simply wasted money - a small persistent leak can waste a surprising amount of water over a year.

How we find it without unnecessary damage

Our leak detection service uses pressure testing and tracing equipment to narrow down the source before any exploratory work begins, keeping disruption and cost to a minimum.
