Say Goodbye to Hidden Leaks and Dampness

Leaks in a house can be one of the most destructive issues you’ll face, potentially causing thousands of pounds worth of damage.

Sadly, not all leaks are covered by your house insurance; floods or burst pipes might be covered, while slow leaks caused by wear and tear or a lack of maintenance are usually not covered.

As a result, if you’ve discovered a potential leak in your home, it’s essential to act quickly to limit damage and costs.

How it works


Think you’ve got a leak?

If you think your home is suffering from a leak, call Causeway Cleaning.

Our goal is to identify the leak, create a safe environment and advise you on how to get it repaired through a local plumbing expert.


Infrared Thermal Imaging Leak Inspections

Once we arrive at your property, we’ll work to identify the problem.

First, we’ll conduct a detailed Infrared Thermal Imaging leak inspection using state-of-the-art equipment: an infrared camera, the FLIR E8 Pro, and a Protimeter MMS3.

Our advanced infrared cameras precisely identify leaks and moisture issues within walls, floors and ceilings that may be causing mould growth.


Non-Invasive Moisture Detection

We can detect excess moisture and water leaks behind surfaces using professional-grade moisture meters without any destructive testing or drilling.


Report and Recommendations

After thoroughly inspecting your home, we’ll provide a detailed report mapping any problem areas and leaks found.

We'll recommend reputable local plumbers to contact for any necessary repairs.

That means when the plumber arrives, they’ll know exactly where to work, saving you time and money.

Sebastian quite literally saved my life. I was faced, unexpectedly, with a severe amount of mould on my kitchen walls when installing a new kitchen. Myself and my young daughter had become ill for sinister unknown reasons. Seb turned up like a SUPERHERO with his gas canister of biocide mould-killing chemicals, and within hours had transformed my home into a sparkling clean, mould-free, disinfected environment. He was friendly and professional at all times and went above and beyond with his advice. Highly recommend this service, it is worth every penny.
