# Find the Hidden Leak Before the Floor Comes Up

Thermal imaging and acoustic tracing locate leaks inside walls, under floors and below ground, so only the right spot gets opened up.

- Leak Detection

## Locate First, Open Up Second

Norbert uses thermal imaging and acoustic tracing to pin down hidden leaks from the surface, so the only hole made is the one needed to reach the pipe.

## Signs It Is Time To Call
- A water bill higher than your usage explains
- A damp patch or stain that keeps spreading
- Warm spots in a floor with nothing above them
- The sound of running water when every tap is off
- A water meter that turns with everything switched off
- Mains pressure that has dropped for no clear reason

## Finding a leak without lifting floors

A hidden leak shows itself indirectly: a ceiling stain, a warm patch in a floor, a water bill that makes no sense. The water rarely appears where the leak is, sometimes surfacing metres away.
- Water runs along joists, down inside walls and under screed first
- A meter that keeps ticking with every tap closed is a clue
- Norbert locates the source from the surface, then opens up only there

## Two methods for two kinds of leak

Thermal imaging suits hot water pipes and radiator runs, showing the warm pattern escaping water leaves. Acoustic tracing suits cold mains and buried pipes, picking up the sound of pressurised water through concrete, tiles or soil.
- A pinhole in a radiator tail shows as a warm streak
- Acoustic is often quickest for supply pipe leaks under drives or gardens
- Pressure testing isolates sections to confirm which run is losing water
- Radiator valve leaks are fixed under [radiator leak repair](https://visionplumbing.co.uk/services/radiator-repair-and-installation/)

## Gas leaks located, then handed over

Norbert can help locate a gas leak. Vision Plumbing is not a gas installer, so the repair goes to a registered gas engineer.
- No work on gas pipework or gas appliances
- No gas certificates issued
- Smell gas? Leave the building and call the gas emergency service first

## After the leak is found

Norbert repairs the water leak he finds, whether a failed joint, a corroded section or a split pipe. He covers Kent, Medway, Surrey, East and West Sussex and south-east London from near Sevenoaks.
- Opened up at one point only, where the leak was located
- Every repair carries a one year warranty on parts and labour
- Water pouring through a ceiling is an [emergency plumber](https://visionplumbing.co.uk/services/emergency-plumber/) job first

## Leak Detection: questions answered

### 01How does thermal imaging find a water leak?

Water escaping from a hot pipe warms the floor, wall or ceiling around it, and a thermal camera shows that as a patch or streak on the screen. Tracing the pattern back leads to where the water is coming from. It works best on hot water and radiator pipework. For cold mains leaks, where there is little temperature difference, acoustic equipment usually does the job better.

### 02What is acoustic leak detection?

Pressurised water escaping through a small hole makes a noise, even when the pipe is buried under concrete or soil. Acoustic equipment amplifies that sound through the surface, and the loudest point sits over the leak. It is particularly useful for mains supply pipes running under drives, gardens and solid floors, where there is nothing to see and no heat to pick up.

### 03Will you need to damage my walls or floors?

Finding the leak itself does not involve breaking anything. Thermal and acoustic surveys work from the surface. To repair the pipe, the floor or wall does have to be opened, but only at the spot where the leak has been located, rather than lifting a whole room in search of it. That smaller opening is usually far less disruptive than guessing.

### 04Can you repair a gas leak once you have found it?

No. Vision Plumbing is not a gas installer and does no work on gas pipework or appliances, and issues no gas certificates. Norbert can help locate where a gas leak is. The repair itself is handed to a registered gas engineer. If you smell gas at any point, leave the property and call the National Gas Emergency Service before ringing anyone else.

### 05Can the findings help with a home insurance claim?

Many home insurance policies include cover for tracing a leak, sometimes called trace and access, separately from the repair. Norbert explains what he found, where the leak is and what caused it, which gives your insurer the information it usually asks for. Check your own policy wording first, as cover and excesses vary between insurers.

### 06Do you find leaks on underground supply pipes?

Yes. The supply pipe between the boundary stop tap and the house is a common place for leaks, often shown by a meter that keeps turning with everything off, or a damp patch in a lawn or drive. Acoustic tracing along the route of the pipe narrows it down to one spot, so only a small hole is needed to reach and repair it.

## Tell Norbert what needs doing

A line about the job is enough. Norbert reads every enquiry himself and rings you back to talk it through before he quotes.
