Leak Detection in London

Our leak detection specialists help homeowners and property managers across London quickly locate hidden water leaks before they cause serious damage.

Early detection prevents costly repairs, damp problems, mould growth and structural damage.

Common Water Leak Problems We Investigate

Our leak detection specialists investigate hidden water leaks in bathrooms, plumbing systems, underground pipework and heating systems.

Undetected leaks can lead to damp issues, mould growth and structural damage within a property if the source of water is not identified quickly. In some cases, properties may also require structural drying services to remove trapped moisture after the leak has been repaired.

If you’re experiencing any of these issues, our leak detection specialists can quickly locate the source using non-destructive leak detection methods and prevent further damage to your property.

Signs You May Have a Hidden Leak

Hidden water leaks often develop slowly and can remain unnoticed for weeks or even months. If you’re experiencing any of the following warning signs, there may be an underlying water leak within your property that requires professional investigation.

In some cases, ongoing leaks can also lead to damp issues or mould growth if the moisture is left unresolved.

If you notice any of these warning signs, our leak detection specialists can quickly locate the source using non-destructive leak detection methods and prevent further damage to your property.

How Our Leak Detection Investigations Work

Our leak detection investigations follow a structured process designed to accurately locate hidden water leaks while minimising disruption to your property. Each investigation begins with a detailed inspection so our engineers can determine the most appropriate leak detection methods for the situation.

Inspection

We begin with a detailed inspection of the affected areas, reviewing visible signs such as damp patches, staining or unexplained moisture that may indicate a hidden water leak. Our engineers also assess plumbing routes, appliances and surrounding areas to identify potential sources of the leak.

Specialist Leak Detection

Once the investigation approach has been determined, we use specialist leak detection methods to locate the source of the problem. Depending on the situation, this may include thermal imaging, acoustic listening equipment or tracer gas testing to accurately pinpoint hidden leaks.

Moisture Testing

Specialist moisture meters are used to confirm moisture levels within walls, ceilings and floors. This helps determine how far water has travelled through the building structure and whether structural drying or remedial work may be required.

Insurance Report

Once the leak is located, we provide a clear report confirming the source of the leak along with supporting photographs and recommended repairs. Our documentation can assist with insurance claims where applicable.

Structural Damage Water Leaks Can Cause

Water leaks are often repaired, but moisture left behind inside walls, ceilings and flooring can continue causing damage if it is not properly addressed. Trapped moisture within building materials can lead to ongoing damp conditions, mould growth and structural deterioration.

In many cases, professional structural drying services may be required to remove trapped moisture and prevent further damage to the building structure.

Below are some of the common types of damage water leaks can cause.

Plaster Damage

Persistent moisture can cause plaster to blow, paint to peel and decorative finishes to stain or bubble. Once the leak has been repaired, affected areas often require replastering and redecorating.

Timber Decay

Timber structures such as joists, skirting boards and flooring can absorb moisture from ongoing leaks. Over time this can weaken the timber and increase the risk of rot.

Ceiling & Floor Damage

Leaks above ceilings or beneath flooring can cause sagging ceilings, warped floorboards and damage to surrounding finishes.

Mould & Damp Growth

Where moisture remains trapped within walls or building materials, mould growth and persistent damp conditions can develop even after the original leak has been repaired.
