Leak Detection Coulsdon
Hidden water leaks in Coulsdon pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Coulsdon buildings.
Local knowledge
Coulsdon housing, from a leak engineer's side
Coulsdon includes larger detached homes on leafy plots alongside more modest semis. The hilly topography means properties often have significant changes in level, requiring careful drainage design and putting extra pressure on pipework. Long, private drain runs to the sewer are common, as are soakaways for surface water. Many properties have outbuildings, swimming pools, or irrigation systems fed from the domestic supply, adding complexity to the network and potential leak points.
Engineer's note
A high water bill or a constantly running meter often signals a hidden leak on your large plot. Call us for immediate detection – delaying can lead to major water loss and foundation issues.
Covered in Coulsdon

What fails here
Common leak problems in Coulsdon
01
Soakaway & Land Drain Failure
Failed soakaways from roof drainage or collapsed land drains cause water to pool near foundations, leading to penetrating damp in lower walls and floors. The first sign is often a perpetually soggy lawn or a suddenly damp cellar wall after rain.
02
Irrigation System Leaks
Underground irrigation systems are vulnerable to frost damage and accidental piercing. A leak here can waste huge amounts of water, dramatically increasing the meter reading, while the surface grass may appear unusually lush.
03
Swimming Pool Pipe Leaks
Leaks in the filtration or vacuum lines of a pool are not always obvious but cause a steady drop in water level and potential structural issues with the pool shell. Dye testing and pressure testing of individual lines is needed to find the breach.
04
Leaks in Stepped Drainage Runs
Drainage on steep plots uses backdrops and stepped sections. A blockage or fracture at a lower step can cause a backup that floods upper sections or outbuildings. A CCTV survey is essential to navigate these complex runs and find the fault.
Three methods, one marked point
Acoustic survey
Ground microphones and correlators follow the sound of escaping water through floors and ground.
Thermal imaging
Infrared cameras reveal wet patches and buried heating runs through the floor surface.
Tracer gas
A safe hydrogen mix escapes through the exact failure point and rises to our surface detector.
Leak detection in Coulsdon — FAQs
How quickly can you attend a leak in Coulsdon?
Same-day appointments are usually available in Coulsdon and across Croydon, and next-day almost always. If water is actively escaping, say so when you book — live leaks are prioritised and we can talk you through isolating the supply while the engineer travels.
What does leak detection cost in Coulsdon?
A fixed fee agreed at booking — typically £250–£450 for a domestic detection visit — covered by no find, no fee. That includes pressure testing per circuit, thermal imaging, acoustic survey and moisture mapping. Repairs are quoted separately before any work starts.
Do you know Coulsdon properties?
Yes — Coulsdon includes larger detached homes on leafy plots alongside more modest semis. The hilly topography means properties often have significant changes in level, requiring careful drainage design and putting extra pressure on pipework. Long, private drain runs to the sewer are common, as are soakaways for surface water. Many properties have outbuildings, swimming pools, or irrigation systems fed from the domestic supply, adding complexity to the network and potential leak points.
Can you provide a report for my insurer?
Every Coulsdon detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
