Leak Detection and Repair in Worthing

Leak detection and repair in Worthing helps find water loss that isn't obvious from the surface, such as a damp patch, a higher water bill, or a boiler that keeps losing pressure. Worthing's older housing stock and hard water can both play a part, and pinpointing the source accurately before any repair work is what stops the same leak recurring.

Our Expertise

Finding the source before repairing anything

A hidden leak can be surprisingly hard to pin down - water often travels along a joist or pipe run before it shows up as a damp patch, so the visible sign isn't always directly above or below the actual source. Proper leak detection uses a combination of visual checks, pressure testing and, where needed, specialist equipment to narrow down the location before any wall, floor or pipework is disturbed to make the repair.

Leak detection - typical approach by sign

What are the signs of a hidden leak?

An unexplained rise in your water bill, damp patches or discolouration on walls and ceilings, a musty smell, or a boiler that keeps losing pressure are all signs worth investigating.

Some signs are obvious, like a visible damp patch, while others are easy to miss - a slightly higher water bill than usual, or a boiler that needs topping up more often than it used to. None of these confirm a leak on their own, but together they're a reasonable prompt to get a proper check done before any damage gets worse.

How is a hidden leak actually found?

Visual inspection, pressure testing of the system, and specialist detection equipment are used together to narrow down a leak's location without unnecessary disruption.

The starting point is usually a visual inspection of accessible pipework and any visible damp signs, followed by pressure testing to confirm whether the system is losing water and roughly how quickly. Where the source still isn't clear, more specialist methods help narrow the search further before any repair work begins - the goal throughout is finding the source accurately rather than opening up more of the property than necessary.

What happens once the leak is found?

The repair itself depends entirely on what's found - a joint reseal, a section of pipe replacement, or in some cases a bigger repipe - and is scoped once the source is confirmed.

Repair scope varies enormously depending on what's actually wrong, from a straightforward joint reseal to a more involved section replacement if the pipe itself has failed. Getting an accurate location first means the repair addresses the actual problem rather than the closest visible symptom, which is what stops the same leak reappearing somewhere nearby a few weeks later.

Frequently asked questions

How do I know if I have a hidden leak?

An unexplained rise in your water bill, a damp patch that doesn't have an obvious cause, or a boiler that keeps losing pressure are the most common early signs worth getting checked.

Will finding a leak mean my walls or floors get opened up?

Not necessarily - detection methods aim to narrow down the location as precisely as possible before any repair work, which limits disruption to only where it's actually needed.

Can a leak affect my boiler?

Yes - a leak in the connected pipework can show up as the boiler repeatedly losing pressure, which is why a boiler-related pressure drop is worth checking against the wider system, not just the boiler itself.

Is a hidden leak an emergency?

A slow hidden leak usually isn't as urgent as an active burst, but it shouldn't be ignored, since ongoing water loss can cause structural damage over time. See our emergency plumber page if water is actively escaping.
