Water on Lanzarote is not a natural resource, it is a manufactured one. With no rivers, lakes, or aquifers, every single litre used on the island begins its life in the Atlantic Ocean before being desalinated at significant cost. We, at Canary Detect, are consistently reminding property owners, “Lanzarote doesn’t collect its water. It manufactures it. Every litre wasted here had to be made first.”
In this environment, water waste is not just inconvenient; it is expensive, energy‑intensive, and potentially destructive. A hidden leak can quietly drain hundreds of euros, damage the structure of a home, and even spread into neighbouring properties long before anyone notices a damp patch or peeling paint. Traditional water bills —arriving every six to eight weeks — simply cannot keep pace with the speed at which damage escalates.
This is the problem LeakGuard was built to solve.
The Leaky Finders: 40 Years of Expertise Meets Modern AI
Canary Detect, known island‑wide as “The Leaky Finders,” has protected over 1,200 Lanzarote properties with specialist leak detection equipment and a reputation for precision. In early 2026, we launched LeakGuard, a 24/7 smart monitoring system that immediately begins catching leaks that would otherwise have gone unnoticed for months.
Now, with Phase 2 of LeakGuard, Canary Detect introduces a major evolution: LeakGuard AI, powered by a trained intelligence affectionately known as Aunt Polly. This upgraded system offers two flexible plans, deeper analytics, and faster, more accurate leak detection than ever before.
And the main thing, LeakGuard really works, we’ve caught numerous leaks for our customers already alerting them to unusual water patterns before they had even realised there was a problem. That’s the power of our LeakGuard system.
Why Hidden Leaks Are So Dangerous
A typical hidden leak on Lanzarote does not merely run up the water bill. When a leak occurs underground or within the structure of a property, the water often soaks into the concrete floor first. From there, it finds its way between the concrete and the tiles, eventually spreading out across the house and reaching the breeze-block walls. Breeze blocks act like sponges, drawing moisture upward and causing severe internal damage long before any signs are visible on the surface.
Consequences include:
- Months of drying time and unsightly walls
- Cancelled holiday bookings and refunded deposits
- Homes in an unsightly and unlivable state
- Damage spreading into neighbouring homes
- Stressful insurance claims and strained relationships
- And that massive water bill
In many cases, the water bill is the cheapest part of the disaster.
LeakGuard AI fundamentally changes this dynamic by catching leaks within 24 hours, long before the concrete gets wet, before the tiles lift, before the walls start drinking the water, and before it ever reaches the property next door. LeakGuard literally spots the leak before anyone else knows it’s there.
Two Jobs, One AI: Catching Leaks & Stopping Waste
LeakGuard AI performs two essential tasks for every property:
1. Catch Sudden Leaks Before They Become Expensive
Aunt Polly monitors water flow every 15 minutes, learning the unique rhythm of your home—showers, pool cycles, irrigation, and more. When something deviates from your normal pattern, she alerts you instantly via phone, email, or WhatsApp.
Real‑world catches include:
- Hidden pipe leaks detected on the very first alert
- Overflow valves stuck open for days
- Leaks with no visible signs that would have run for months
The Leaky Finders are immediately on hand to locate and repair the issue. Real-world catches have proven the system’s effectiveness time and again. Aunt Polly alerts both you and us at The Leaky Finders so we can be proactive and act fast.
2. Stop Silent, Continuous Water Waste
Not all waste is dramatic. Some is quiet, constant, and costly:
- A passing toilet running all night
- A dripping tap adding litres every hour
- A pool cleaner’s hose left running after a visit
LeakGuard AI shows live usage for pools, gardens, and irrigation, exposing overnight waste and saving both water and money. “A water meter cannot lie, and neither can anyone who touches one.”
If anything it’s these kind of leaks that we see on a more regular basis, these are the ones that can go unnoticed for months especially if your villa is a holiday rental or empty.
How LeakGuard AI Works
LeakGuard AI is installed directly at your water meter using a self‑contained 4G device. It requires:
- No Wi‑Fi
- No mains power
- No invasive work
A qualified surveyor fits the device, hides the flush lid under picón or within the wall, and leaves the property looking untouched. We do all the configuration for you.
Inside the device lives Aunt Polly, the AI bookkeeper who “checks the ledger” rather than guessing. She reads your meter around the clock, understands your household’s normal behaviour, and flags anything unusual with precision. She knows what normal looks like for you. As Aunt Polly herself says, “I don’t guess. I check the ledger.” By understanding these patterns, she does not have to guess; she checks the data, and every alert is grounded in your real numbers, to the cent. Whether it is a burst pipe or a silent running toilet, Aunt Polly identifies the issue and sends an alert. This dual capability ensures that property owners are never caught off guard.
Built for Every Type of Property
LeakGuard AI is designed to protect:
- Villas: A slow drip under a terrace can run for weeks unnoticed. LeakGuard AI catches it overnight, ensuring your property is protected even when you are off the island.
- Holiday Rentals: Guests rarely report a hidden leak, often not noticing or simply ignoring the signs. The system monitors water usage between bookings and alerts the property manager the moment usage looks wrong, preventing cancelled bookings and the hassle of refunded deposits.
- Commercial Properties: Restaurants, hotels, and businesses face significant water costs. Continuous monitoring keeps consumption in check and prevents minor plumbing issues from becoming major operational expenses.
Transparent and Flexible Pricing
LeakGuard AI offers two clear plans, both with an installation fee starting from €350 (subject to survey, plus 7% IGIC):

The Plus plan is the most popular, offering full analytics, usage history, and conversational insights from Aunt Polly.
Conclusion
For Lanzarote property owners, water is too precious and too expensive to waste. Hidden leaks cause structural damage, financial loss, and months of disruption. LeakGuard AI provides a modern, intelligent, always‑watching solution that protects homes, conserves water and saves money.
With Aunt Polly guarding the meter, the days of waiting for a shocking water bill to discover a leak are finally over.
LeakGuard is your eyes and ears for water leaks giving you peace of mind that if the worst does happen, we can spot it and react fast.
