Hidden leaks

Leak detection,
find it before it floods.

Hidden leaks can quietly destroy floors, ceilings, and pipework. We use thermal imaging, acoustic equipment, and tracer-gas detection to find leaks fast — without ripping up your home.

Signs of a hidden leak

Unexplained rise in water bills

If your usage hasn't changed but your bill has spiked, water is going somewhere you can't see.

Damp patches on walls or ceilings

Yellow stains, peeling paint, or wallpaper bubbling — classic signs of slow water ingress.

Constant boiler pressure drop

If you keep topping up your boiler, there's likely a leak in the central heating circuit.

Sound of running water

When all taps are off but you can still hear water moving — pipework leak somewhere.

Mould or musty smell

Persistent damp and mould suggest moisture is escaping behind the structure.

Warm patches on cold floors

A hot-water leak under tiles or wood can heat the floor above it.

The process

How it works

  1. 1

    Initial assessment

    We talk through what you've noticed and where you suspect the leak is. Helps us narrow the search before equipment comes out.

  2. 2

    Pressure & sound test

    Acoustic listening devices and pressure tests on individual circuits to localise the leak to a specific zone.

  3. 3

    Thermal imaging

    Infrared camera shows temperature differences from leaking water — usually a clean visual confirmation.

  4. 4

    Tracer gas if needed

    For tricky leaks behind structure, we introduce a safe tracer gas into the pipework and detect where it escapes.

  5. Quote & repair

    Once the leak is found, we'll quote the repair and get it sorted — same visit if possible.

FAQ

Common questions

How much does leak detection cost?
Our leak detection callout is a fixed fee — you'll know the price before we start. If we find and repair on the same visit, the repair is quoted separately and clearly.
Do you damage walls or floors?
No. Our equipment is non-invasive — thermal cameras, acoustic listening, and tracer gas. The only opening we make is a small access hole at the exact leak point, if needed for repair.
How quickly can you respond?
For active leaks we'll prioritise — usually same day across Surrey and Sussex. For ongoing investigation we book within 1–2 days.
Will my insurance cover the leak?
Most home insurance policies cover trace and access. We provide a full written report you can submit with your claim.
