Hidden leaks rarely announce themselves clearly — they show up as small, easy-to-dismiss signs first. These are the patterns Islington homeowners tell us about most.
Common in Highbury and Angel’s period properties, where a stain can point to a leak well away from where it appears.
A steadily climbing bill with no change in usage is often the first sign of an underground or concealed supply leak.
A gradual pressure drop across taps can indicate a leak feeding off the mains supply somewhere in the system.
Common in Archway and Highbury gardens — a persistently soggy patch of lawn often traces back to a split supply pipe.
A methodical, non-invasive process designed to find the exact source of a leak before any repair work is even discussed.
We review the signs you've noticed, check the water meter, and identify the likely area of the property to investigate first.
Acoustic listening equipment, thermal imaging and tracer gas are used to pinpoint the leak without lifting floors or opening walls.
Once located, we confirm the exact position and cause, and provide a fixed price for repair before any further work begins.
If you'd like us to carry out the repair, it's completed, tested, and signed off with a written report the same visit where possible.
Different leaks need different detection methods — our engineers are equipped for all of them.
Sensitive listening equipment picks up the sound of water escaping under pressure, even through walls, floors and underground pipework.
Identifies temperature differences caused by escaping water or heating fluid, useful for tracing leaks behind walls and under floors.
A safe, non-toxic tracer gas is introduced into the system and detected as it escapes — highly accurate for hard-to-locate leaks.
Guesswork leads to unnecessary damage. A proper detection survey protects your home and your budget.
Non-invasive methods mean we don’t open up walls or lift floors speculatively — only where the leak is confirmed.
An undetected leak can run for months, quietly inflating your bill. Finding and fixing it stops the waste at the source.
Left long enough, hidden leaks can cause rot, mould and damage to foundations — catching it early avoids costly repairs later.
A written report with findings and photos, useful if you need to support an insurance claim for water damage.
Fixed prices agreed before we start. Any repair work is quoted separately once the leak is confirmed.

From Highbury's period homes to Angel and Holloway's flats and conversions.
Our detection survey stands alone — you're never obligated to book a repair with us once the leak is found.
Same pricing whether you're in N1 Angel or N19 Archway. No zone uplift, ever.
Reg. No. 123456 — essential when a hidden leak is near a boiler or gas appliance.
Hundreds of Islington homeowners have rated our leak detection service five stars for accuracy and minimal disruption.

“Our water bill had almost doubled with no explanation. The engineer used tracer gas and found a split supply pipe under the garden in about two hours, without digging up the whole thing first.”
“Damp patch kept appearing on our lounge ceiling in our Highbury house. Thermal imaging traced it to a heating pipe two rooms away — repaired the same day, no unnecessary holes in the wall.”
“Persistent wet patch in the garden for months in our Finsbury Park house. Turned out to be a leaking supply pipe, found accurately and quickly. Fixed price throughout, no surprises.”
We use acoustic listening equipment, thermal imaging and tracer gas to pinpoint the location of a leak without needing to dig up gardens or open walls speculatively. Each method suits different leak types, and your engineer will select the right approach based on the signs you've noticed.
No. Our leak detection survey is a standalone service. Once the leak is located, you'll receive a fixed price for the repair, but there's no obligation to book that work with us.
Yes. We provide a written report with our findings and photographs from the survey, which you can use to support a home insurance claim for water damage.
We typically schedule leak detection surveys within 24 to 48 hours of your enquiry. If the leak is causing active flooding or significant water loss, call our emergency line and we'll prioritise a faster response.
Don’t guess or start digging. Book a non-invasive leak detection survey and get a clear answer, fast.
