What You'll Actually Pay for Pool Leak Detection in Lanzarote

When your pool keeps dropping water, the first question is usually: "How much will it cost to find the problem?" It's a fair question, and one that deserves a straight answer.

Pool leak detection on our island typically ranges from €150 to €400, depending on the complexity of your pool and what methods are required. Let me explain exactly what determines where your situation falls on that scale.

Breaking Down the Real Costs

Basic Inspection: €150-200

This entry-level service includes:

Visual examination of the entire pool structure

Checking all fittings, returns, and drain covers

Dye testing around suspected areas

Pressure testing of accessible pipework

Basic report on findings

For straightforward situations where the leak is in an accessible location, this level of investigation often identifies the source. Many pool owners find their problem is nothing more than a cracked fitting or deteriorated gasket.

Comprehensive Detection: €250-350

When basic inspection doesn't reveal the culprit, more sophisticated methods become necessary:

Acoustic leak detection uses sensitive microphones to listen for the sound of escaping water underground or within pool walls. This technology can locate leaks in buried pipes without excavation.

Electronic leak detection employs specialized equipment that identifies the precise location of breaches in vinyl liners or through concrete structures.

Pressure testing with isolation systematically tests each section of your pool's plumbing to identify which line has failed.

This comprehensive approach suits pools with complex plumbing or suspected subsurface issues.

Complex Investigations: €350-400+

Certain situations require extended investigation time:

Pools with multiple suspected leak points

Infinity edge or overflow designs with intricate hydraulics

Heated pools with extensive underground pipework

Commercial or community pools with large surface areas

These investigations may span several hours and employ multiple detection technologies.

What Actually Affects the Price

Pool Size and Design

A simple rectangular pool with standard fittings takes less time to assess than one with beach entries, grottos, integrated spas, or extensive water features. Each additional element adds potential failure points.

Pool Age and Construction Type

Pools built in the 1980s and 1990s often used materials and methods that have specific failure patterns. Concrete pools from this era may have delamination issues, while fibreglass shells can develop osmotic blistering.

Accessibility

Pools surrounded by extensive decking, built-in furniture, or landscaping that restricts access to pipework increase investigation complexity. If we can't easily reach a potential problem area, alternative detection methods take longer.

Previous Repair History

Pools that have undergone multiple repairs may have unusual routing of replacement pipes or non-standard fittings that complicate systematic testing.

What Should Be Included

Any reputable leak detection service should provide:

Written report: Documenting all findings, including photographs where relevant.

Precise location marking: If a leak is found, its exact position should be marked on-site.

Repair recommendations: Clear guidance on what needs fixing and approximate repair costs.

No-find policy: Many specialists offer reduced fees or partial refunds if no leak is located despite thorough investigation.

Questions to Ask Before Booking

When contacting specialists, clarify:

What's included in the quoted price?

What happens if the initial investigation doesn't find the leak?

Do you provide written reports?

What detection methods do you use?

How long will the investigation take?

These questions help you compare quotes accurately rather than just choosing the lowest number.

When Detection Isn't Needed

Not every water loss requires professional detection. Before booking, eliminate these common causes:

Evaporation: Lanzarote summers can remove 5-7mm daily from an uncovered pool. Use the bucket test (explained in our other articles) to distinguish evaporation from leaks.

Splash-out: Active pool use, particularly with children, removes more water than most owners estimate.

Backwash waste: Sand filter maintenance consumes 200-400 litres per backwash cycle.

Winterisation drainage: Some pools are partially drained seasonally, leading to confusion about normal levels.

The Value Perspective

Consider what delayed detection costs you:

Continued water bills of €3-5 per cubic metre

Chemical imbalances from constantly adding fresh water

Pump strain from air ingestion through failing pipes

Potential structural damage from water escaping beneath the pool

A €300 detection service that identifies a €150 repair saves thousands in continued water loss and prevents escalating damage.

Choosing a Specialist

Look for detection services that:

Focus specifically on leak detection rather than offering it as a side service

Use modern electronic and acoustic equipment

Provide references from previous pool work

Offer clear, fixed-price quotes rather than hourly estimates

Have specific experience with Lanzarote's pool infrastructure

Pool leak detection is precision work requiring specialized skills and equipment. The most experienced technicians quickly narrow down possibilities, often identifying issues that less specialized services might miss.

Your pool represents a significant investment in your property. Professional leak detection protects that investment while stopping the steady drain on your water bills.
