Thermal Imaging Leak Detection Lanzarote | Leakbusters

Here at Leakbusters Lanzarote, our team of leak detection specialists shares their expertise.

The Science Behind Thermal Leak Detection

When water escapes from pipes hidden within walls, under floors, or beneath your property, it creates temperature differences that are invisible to the naked eye. Thermal imaging cameras detect these temperature variations, revealing the precise location of hidden leaks without any need for destructive investigation.

At Leak Busters Lanzarote, we use professional-grade FLIR thermal imaging equipment — the same technology used by firefighters and industrial inspectors worldwide. This allows us to see what traditional methods cannot: the thermal signature of moisture hiding behind surfaces.

How Thermal Imaging Works for Leak Detection

The Physics of Temperature Variation

Water leaking from a pipe affects the surrounding temperature in predictable ways:

Evaporative cooling: As leaked water evaporates, it draws heat from surrounding materials. This creates cold spots visible on thermal cameras even when no moisture is visible to the eye.

Conductive patterns: Water spreads through building materials following paths of least resistance. Thermal imaging reveals these moisture migration patterns, allowing us to trace leaks back to their source.

Material saturation: Wet materials have different thermal properties than dry ones. A soaked wall absorbs and releases heat differently, creating distinct thermal signatures.

What We See Through the Camera

Our FLIR cameras display temperature as colour gradients. In a typical scan:

Blue and purple areas indicate cooler temperatures (potential moisture)

Red and orange areas show warmer temperatures

Yellow and white represent the hottest zones

When scanning a wall or floor, a hidden leak appears as an irregular cooler zone that doesn't match the expected thermal pattern of the building.

Where Thermal Imaging Excels

Behind Walls Without Destruction

Traditional leak detection often meant cutting holes in walls to investigate suspicious areas. With thermal imaging, we scan entire walls in minutes, identifying exactly where moisture exists before any investigation work begins.

This is particularly valuable in Lanzarote properties where:

Thick stone walls make invasive investigation expensive

Holiday rental properties cannot afford extended repair downtime

Heritage buildings require preservation of original features

Underfloor Heating Systems

Many Lanzarote villas feature underfloor heating — a luxury that becomes a liability if leaks develop in the buried pipe network. Thermal cameras show us the exact routing of heating pipes and highlight any areas where water escapes the system.

Without thermal imaging, underfloor heating leaks often require lifting entire floor sections to locate. Our technology pinpoints the problem to within centimetres, minimising disruption.

Flat Roof Inspections

Lanzarote's characteristic flat roofs are vulnerable to water ingress, but finding the actual entry point can be challenging. Water often travels horizontally under waterproof membranes before appearing as a stain inside.

Thermal roof inspections reveal:

Areas where moisture has accumulated under the surface

The path water takes from entry to visible damage

Defects in insulation where thermal performance has degraded

Pool Plumbing Systems

Pool leak detection combines several techniques, but thermal imaging plays a crucial role in identifying leaks in buried pool pipework. The temperature differential between leaked water and surrounding volcanic soil creates clear signatures on our equipment.

Case Study: Puerto del Carmen Villa

A property owner in Puerto del Carmen contacted us after noticing their water bills had increased by 40% over three months. There were no visible signs of leaks anywhere in the property.

The challenge: The villa had extensive gardens with irrigation, a pool, and underfloor heating in the living areas. The leak could have been anywhere in over 200 metres of buried pipework.

Thermal imaging approach: We systematically scanned all accessible surfaces. Within 30 minutes, we identified an unusual cold spot on the terrace floor near the pool equipment room.

The discovery: A supply pipe to the pool filtration system had developed a pinhole leak at a fitting. Water was escaping into the volcanic gravel beneath the terrace — invisible from above but clearly visible to our thermal camera.

The outcome: Repair required lifting just four terrace tiles rather than excavating the entire pool equipment area. Total repair time: 3 hours instead of potentially days of investigation.

Thermal Imaging vs Traditional Methods

Acoustic Listening Devices

Acoustic leak detection listens for the sound of escaping water. This works well for pressurised pipes with active flow, but has limitations:

Requires the leak to be actively producing sound

Background noise can interfere with detection

Cannot detect very slow seepage

Less effective on plastic pipes than metal

Thermal imaging complements acoustic methods by detecting moisture regardless of whether water is actively flowing at the moment of inspection.

Moisture Meters

Handheld moisture meters measure dampness at specific points. While useful for confirming moisture presence, they cannot:

Scan large areas quickly

Detect moisture behind thick materials

Show the extent and pattern of water spread

Work without direct surface contact

We often use moisture meters to confirm thermal findings, but the camera provides the initial wide-area assessment.

Tracer Gas

Tracer gas methods introduce harmless gases that escape through leak points and can be detected at the surface. This is highly effective but:

Requires isolating and pressurising systems

Takes longer to set up and execute

May not locate leaks in inaccessible areas

Thermal imaging often identifies the general area before tracer gas confirms the precise point.

The FLIR Technology We Use

Our equipment includes the FLIR E-Series professional thermal cameras with:

Temperature sensitivity of 0.05°C — detecting the smallest variations

High resolution sensors for detailed imaging

Multiple colour palettes for different inspection scenarios

Image storage and reporting capabilities

This professional equipment differs significantly from consumer thermal cameras or smartphone attachments, which lack the sensitivity required for accurate leak detection.

When to Request Thermal Inspection

Ideal Scenarios for Thermal Detection

Thermal imaging is particularly effective when:

You suspect a leak but cannot see any visible signs

Water bills have increased without explanation

Damp patches appear and disappear

You're purchasing a property and want a thorough inspection

Previous repair attempts have failed to resolve issues

Limitations to Understand

Thermal imaging performs best under certain conditions:

Temperature differential: The bigger the difference between leaked water and ambient temperature, the clearer the signature. Very cold water in very cold conditions, or warm water in hot conditions, may be harder to detect.

Material density: Very thick materials or those with reflective surfaces can reduce thermal visibility. Metal panels and some tiles may require different scanning angles.

Time factor: Very fresh leaks may not have created sufficient thermal variation yet, while very old leaks where materials have reached equilibrium may show reduced contrast.

Our technicians understand these variables and adjust techniques accordingly.

Cost Benefits of Early Thermal Detection

Preventing Water Damage

The average cost of water damage repair in Lanzarote properties ranges from €2,000 to €15,000 depending on extent and materials affected. Early detection through thermal imaging typically costs a fraction of potential repair bills.

Reducing Investigation Costs

Traditional leak investigation often meant exploratory demolition — opening walls and floors hoping to find the problem. Each access point costs money to create and repair. Thermal imaging targets investigation precisely, often reducing access work by 80% or more.

Protecting Property Value

Water damage affects property resale value and can complicate sales if moisture problems are discovered during buyer surveys. Regular thermal inspections provide documentation of property condition and early warning of developing issues.

What to Expect During a Thermal Survey

When you book a thermal leak detection survey with Leak Busters Lanzarote, here's what happens:

Initial consultation: We discuss your concerns, property type, and any symptoms you've noticed. This helps us plan the most effective scanning approach.

Property preparation: For best results, we may ask you to run heating or hot water systems before our arrival, or to ensure certain areas are accessible.

Systematic scanning: Our technician works methodically through the property, capturing thermal images of all relevant surfaces. This typically takes 1-2 hours for a standard villa.

Real-time explanation: We show you what we're seeing on camera and explain any findings as we work.

Written report: You receive a detailed report with thermal images, our findings, and recommendations for any required repairs.

Combining Technologies for Best Results

At Leak Busters Lanzarote, thermal imaging is one tool in our comprehensive detection toolkit. Depending on your situation, we may combine thermal scanning with:

Water leak detection using acoustic methods

Pipe inspection using CCTV cameras

Underground detection using ground-penetrating radar

This multi-technology approach ensures we find problems that any single method might miss.

Frequently Asked Questions

Is thermal imaging safe for my home?

Completely safe. Thermal cameras are passive devices that detect naturally occurring temperature variations. They emit nothing and pose no risk to people, pets, or electronics.

Can thermal imaging see through walls?

Not exactly. Thermal cameras detect surface temperatures, but temperature variations caused by moisture behind walls show through as the surface temperature changes. It's indirect detection rather than seeing through materials.

How accurate is thermal leak detection?

In experienced hands, thermal imaging locates leaks to within 10-20 centimetres in most situations. Combined with confirmation methods, accuracy approaches centimetres.

Does the weather affect thermal surveys?

Significant temperature changes immediately before a survey can affect results. We typically avoid scanning exterior surfaces during direct sunshine and prefer stable temperature conditions. Interior scans are less weather-dependent.

Can I buy a thermal camera and do this myself?

Consumer thermal cameras lack the resolution and sensitivity for reliable leak detection. Professional equipment costs €10,000+ and requires training to interpret correctly. For occasional property checks, professional surveys are more cost-effective.
