Here at Leakbusters Lanzarote, our team of leak detection specialists shares their expertise on preventing water damage in Lanzarote.

Introduction: Why Water Damage Prevention Matters in Lanzarote

Preventing water damage in Lanzarote is crucial for property owners, managers, and residents who want to protect their investments and maintain the value and safety of their homes or businesses. This article covers the unique risks of water damage on the island, practical prevention strategies, and expert tips tailored to Lanzarote's climate and construction. Whether you own a holiday rental, manage a commercial property, or live on the island year-round, understanding and addressing water damage risks is essential due to Lanzarote's arid climate, reliance on desalinated water, and exposure to sea salt.

Main Sources of Water Damage in Lanzarote

Preventing water damage in Lanzarote requires addressing two main sources:

Intense, infrequent torrential rains: These rare but powerful storms can overwhelm drainage systems and cause rapid flooding.

The constant, corrosive impact of sea salt: Sea salt in the air and water supply accelerates corrosion and deterioration of building materials and plumbing systems.

The Paradox of Water Damage on a Dry Island

Lanzarote receives barely 112mm of annual rainfall — less than almost any inhabited place in Europe. Yet water damage remains one of the most significant risks facing property owners across the island. This apparent contradiction makes perfect sense once you understand how water moves through and around Lanzarote properties.

The very aridity that defines our climate makes water damage more insidious, not less. Properties aren't designed for moisture. Building materials lack the water resistance common in wetter climates. And when leaks occur, they often go unnoticed far longer than they would in regions where people expect water problems.

Understanding Lanzarote's Water Damage Risks

Internal Plumbing Failures

The most common source of water damage in Lanzarote properties comes from within. Our reliance on desalinated water, coupled with ageing infrastructure in many developments, creates constant pressure on internal plumbing systems.

Properties in Puerto del Carmen, Costa Teguise, and other tourist-developed areas often date from intensive 1980s construction. These buildings now have plumbing systems 40+ years old — well beyond the design life of many original components. Properties in Lanzarote often have plumbing systems that are over 40 years old, increasing the risk of failures.

Common internal failure points:

Supply connections: Under sinks and behind appliances

Toilet components: Fill mechanisms and wax seals

Water heater connections: Including relief valves

Washing machine hoses: Inlet hoses

Shower tray seals: And grout lines

Preventive replacement: Replace washing machine and dishwasher hoses every five years to prevent bursting

Each of these can fail suddenly after years of trouble-free operation. The damage from a burst supply hose or failed connection can flood a property within hours, especially in holiday homes where discovery may be delayed.

Preventive maintenance is key to avoiding costly plumbing emergencies in Lanzarote properties. Utilize local services for routine plumbing checks to identify small, persistent leaks. Leakbusters offer homeowners specialized services to handle plumbing issues proactively, ensuring peace of mind and reducing the risk of emergencies.

Pool and Irrigation Systems

Many Lanzarote properties include swimming pools and irrigated gardens — systems that contain and move thousands of litres of water daily. When these systems leak, the water often percolates through volcanic soil without surface evidence.

Pool leak detection frequently reveals problems that have been developing for months or years. A pool losing 3mm daily through a structural crack wastes over 3,000 litres monthly — and that water goes somewhere, often toward foundations or underground structures.

Irrigation systems present similar hidden risks. Broken drip lines, failed sprinkler heads, and root-damaged underground pipes can saturate soil around foundations without any visible indication until structural damage becomes apparent.

Rare but Intense Rainfall

When Lanzarote does receive rain, it often arrives in concentrated bursts. These sudden downpours overwhelm drainage systems designed for minimal rainfall. It is important to prepare for storms, including sea storms, by securing property and avoiding dangerous areas during heavy surf and storm warnings. Properties can flood rapidly when:

Roof drains block with accumulated dust and debris

Flat roof waterproofing has degraded

Ground-level drains cannot handle sudden volume

Retaining walls lack proper drainage

Regular cleaning of roof drainage systems is recommended before the main rainfall period in Lanzarote.

The calima phenomenon — Saharan dust storms — deposits fine particulates that later combine with rain to form a clay-like sludge that blocks drains and waterproofing layers.

Humidity Events

Several times annually, Lanzarote experiences high humidity events when weather patterns trap moist air against the island. Condensation forms on cold surfaces, inside wall cavities, and within mechanical systems. Mold and damp patches are often located in rooms with poor ventilation or in basements.

These humidity spikes can cause:

Mould growth in concealed spaces

Electrical system damage from moisture

Deterioration of wooden elements

Corrosion of metal components

To prevent mold growth, utilize electric dehumidifiers or passive damp-traps in rooms with high moisture, especially in poorly ventilated areas or basements. Ensure proper airflow by opening windows daily to reduce indoor humidity, or consider installing ventilation systems. Do not dry clothes inside without adequate ventilation, as this adds significant moisture to the air.

Properties with air conditioning may experience more severe condensation issues as cooled interior surfaces attract moisture during humid periods.

Detecting Hidden Leaks

Hidden leaks are one of the most significant risks facing Lanzarote properties, often developing out of sight within walls, under floors, or beneath pool areas. Because these leaks can go undetected for long periods, they pose a serious threat to the integrity of your plumbing systems and the overall value of your property. For property managers and homeowners alike, the ability to locate leaks quickly is essential to prevent further damage and avoid costly repairs.

Modern leak detection is a professional service specifically designed to address the unique challenges of Lanzarote's construction and climate. Using advanced technology such as sensitive acoustic sensors, thermal imaging, and specialized equipment, expert teams can pinpoint the exact location of hidden leaks without invasive work. This smart way of handling plumbing issues not only protects your property from major damage but also saves you money by addressing problems before they escalate.

Regularly monitoring your water meter is a key step in early leak detection. Unexplained increases in water usage can be the first sign of a hidden leak. By staying vigilant and checking your water meter readings, you can catch leaks before they cause significant damage to your walls, floors, or foundations. Property managers should also keep an eye on weather forecasts, as heavy rain can reveal or worsen existing leaks, especially in older plumbing systems or around pools and drains.

Preventing corrosion and maintaining your plumbing systems is just as important as detecting leaks. Routine inspections of drains, pool equipment, and plumbing connections help identify early signs of wear or damage. By taking these proactive steps, property owners can reduce the risk of leaks and extend the life of their Lanzarote home or business.

Pool systems: Pool circulation and heating systems

Business continuity planning:

Shutoff knowledge: Know location of main shutoff valves

Emergency contacts: Have emergency plumber contacts readily available

Flood sensors: Consider flood sensors in high-risk areas

Insurance: Maintain appropriate insurance coverage

Technical Prevention Measures

Smart Water Monitoring

Modern technology offers several options for early leak detection:

Flow-based systems: Monitor water usage patterns and alert to anomalies. A toilet running at 3 AM in an unoccupied property triggers an immediate notification.

Moisture sensors: Placed in vulnerable locations (under sinks, behind appliances, near water heaters) provide alerts when water reaches unintended areas.

Automatic shutoff valves: Can close the main water supply when sensors detect problems, limiting damage in unoccupied properties.

These systems are particularly valuable for holiday homes and investment properties where owners aren't present to notice developing problems.

Building Waterproofing Maintenance

Lanzarote's climate requires specific attention to waterproofing systems:

Flat roof coatings: Degrade in UV exposure and thermal cycling. Professional inspection every 3-5 years identifies developing issues before interior damage occurs.

Wall coatings: Should be appropriate for the local climate. Traditional lime-based renders breathe better than modern waterproof paints, which can trap moisture within walls.

Below-grade waterproofing: Around basements, semi-underground parking, and foundation walls needs periodic inspection, particularly after any seismic activity.

Drainage System Maintenance

Functional drainage prevents water accumulation around foundations:

Roof drainage: Systems require annual cleaning, ideally before the main rainfall period (typically November-February). Check downspouts for blockages and ensure water discharges well away from foundations.

Ground drains: Around pools, patios, and entrances accumulate volcanic dust. Regular clearing prevents backup during rain events.

French drains: Or similar perimeter systems require verification that they still function. Volcanic soil can compact over time, reducing drainage effectiveness.

Water Meter and Leak Detection

Protecting your Lanzarote property from hidden leaks starts with one of the simplest tools at your disposal: your water meter. Regularly monitoring your water meter is a smart way to catch water leaks early, often before they cause major damage to your walls, floors, or plumbing systems. Even a small, undetected leak can lead to significant issues over time, especially given the unique weather and construction conditions on the island.

When Damage Occurs: Immediate Response

Despite best prevention efforts, water damage sometimes occurs. Rapid response significantly limits overall damage:

First 30 minutes

Stop the water source: Main shutoff if necessary

Begin water removal: If safe

Document damage: With photographs

Contact property manager or insurance: For rentals or personal property

First 24 hours

Arrange professional water extraction

Begin drying processes

Assess structural concerns

Contact leak detection services: If source is unclear

First week

Monitor for mould development

Complete insurance documentation

Plan necessary repairs

Address root cause: To prevent recurrence

The key is understanding that water damage worsens exponentially with time. Mould can begin developing within 24-48 hours in Lanzarote's conditions. Structural materials absorb more moisture the longer they're exposed.

Insurance Considerations

Water damage insurance in Spain — and specifically on Lanzarote — has particular characteristics:

Community insurance: In apartment complexes typically covers common areas and structural elements. Individual contents and improvements require separate coverage.

Gradual damage exclusions: Mean that slow leaks discovered after long development may face claim challenges. Regular maintenance documentation helps establish that damage was sudden rather than gradual.

Holiday rental policies: Need to specifically address periods of non-occupation. Standard homeowner policies may have exclusions for prolonged vacancy.

Pool coverage: Varies significantly between policies. Ensure your coverage explicitly addresses pool structure, equipment, and related water damage.

Lanzarote-Specific Prevention Tips

Managing Aljibes (Water Storage Tanks)

Traditional rooftop water tanks are common across Lanzarote. These systems require attention:

Float valve check: Check float valves annually to prevent overflow

Seal inspection: Inspect tank seals for deterioration

Overflow verification: Verify overflow pipes discharge safely

Tank covers: Consider tank covers to reduce evaporation and debris entry

Protecting Against Calima Effects

Saharan dust events deposit material that affects water systems:

Pool cover: Cover pool when calima is forecast

Drain cleaning: Clean roof drains after significant dust events

Tap flushing: Flush outdoor taps after extended calima periods

AC condensate check: Check air conditioning condensate lines

Seasonal Considerations

Winter (November-February): Maximum rainfall risk. Ensure drainage clear, check waterproofing, monitor weather forecasts.

Summer (June-September): Maximum thermal stress on plumbing. Check connections, monitor for pool evaporation versus leaks.

Shoulder seasons: Humidity events more common. Watch for condensation issues, especially in closed-up properties.

Frequently Asked Questions

How can water damage be a risk on such a dry island?

Most water damage in Lanzarote comes from internal plumbing failures, not weather. The island's reliance on pressurised desalinated water, combined with ageing infrastructure, creates constant leak potential. When it does rain, concentrated downpours can overwhelm systems designed for minimal rainfall.

What's the most important preventive measure I can take?

Regular water meter monitoring. Checking your meter weekly catches developing leaks before they cause major damage. A toilet mechanism failure or underground pipe leak will show as increased consumption long before visible damage appears.

Should I shut off water when my holiday property is empty?

For extended vacancies (over 4 weeks), consider main water shutoff. This eliminates the risk of burst supply lines flooding an empty property. For shorter periods, regular property checks may be sufficient.

How does Lanzarote's climate affect mould risk?

While generally dry, Lanzarote experiences periodic humidity events that create mould-friendly conditions. Properties with existing moisture from leaks are particularly vulnerable during these periods. Once established, mould can persist even when humidity returns to normal levels.

What should I do if I discover water damage?

Stop the water source immediately, document everything with photos, begin water removal if safe, and contact professionals. Speed is essential — water damage compounds rapidly. Contact our team for leak source identification if the origin isn't obvious.

Are older properties at higher risk?

Yes. Properties built before 1995 typically have plumbing materials now reaching end-of-life. Galvanised steel pipes corrode, early PVC becomes brittle, and decades of ground movement stress all connections. Older properties benefit from proactive plumbing assessment.
