About this service
Water leak detection in Kingston upon Thames, found without ripping up your floor
A damp patch, a boiler that keeps losing pressure, or a water bill that's crept up for no obvious reason — all classic signs of a hidden leak. We use listening equipment and thermal imaging to trace it to within a few centimetres before anyone lifts a floorboard, which saves you money and mess compared to searching by guesswork.
Most home insurance policies include "trace and access" cover, meaning the cost of finding the leak (even if not fixing it) is often covered. We'll give you a written report suitable for a claim either way.
Signs of a hidden water leak
A water meter that moves when nothing is running, a boiler that needs topping up every few days, damp or warm patches on a floor, mould or a musty smell with no obvious source, or the sound of running water when every tap is off.
How we find it
Acoustic listening equipment picks up the sound of water escaping under pressure. Thermal imaging shows warm pipe runs and the spread of moisture behind surfaces. Pressure testing then confirms which circuit is losing water: mains, hot water or central heating.
Leaks under floors and in walls
Once the leak is located we open up only that spot, make the repair and re-test. If the pipe itself is failing along its length, we explain the options on our pipe repair service before you spend anything.

Leak detection in Kingston, Surbiton and New Malden
Many Kingston and Surbiton homes have pipework buried in solid ground floors or run under suspended timber floors, and plenty of New Malden and Chessington houses have had extensions built over the original supply pipe. That is exactly where leaks hide longest.
We trace leaks across the borough, including Norbiton, Berrylands, Tolworth, Old Malden and Hook (KT1, KT2, KT3, KT5, KT6, KT9), in houses, flats and rental properties.
If water is pouring out, call our emergency plumber in Kingston or see burst pipe repairs. Hidden leaks often show up as low water pressure. Maxfix is a local Kingston plumber covering every KT postcode.

Frequently asked
Leak detection FAQs
How do I know if I've got a hidden leak?
Try the 30-minute meter test: turn off every tap and appliance, read your water meter, wait 30 minutes without using any water, then read it again. Any movement means water is escaping somewhere on your side of the stopcock.
Will you need to damage my walls or floors to find it?
Rarely. Acoustic and thermal equipment usually pinpoints a leak without any exploratory digging.
Is leak detection covered by my home insurance?
Many policies include trace and access cover, which pays for finding the leak. Cover varies, so check your policy. We provide a written report you can send to your insurer.
Why does my boiler keep losing pressure?
If you are topping it up more than once or twice a year, water is leaving the heating system somewhere: a radiator valve, a joint under the floor, or a fault inside the boiler such as the pressure relief valve. We test to find out which before anything is replaced.
