Leak Detection for New Malden homes
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.
New Malden's a mix of 1930s semis and newer developments — we cover boiler repairs, emergency plumbing and bathroom installations across the whole area.

Frequently asked
Your questions, answered
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.
Which parts of New Malden do you cover for leak detection?
We cover the whole of New Malden and the surrounding KT3 postcodes. Local engineers means short response times across every street.
