Leak & Fault Finding

Find the leak in an hour. Save the floor.

Water in the wrong place is expensive. Rather than digging up your floor to find a leak, we use acoustic microphones, thermal imaging and dye tracing to pinpoint it — then repair with the minimum possible disruption.

Warning signs

  • Damp patches with no obvious cause
  • Musty smells inside cupboards or walls
  • Higher water bill than expected
  • Insurance claim requiring leak location evidence

Common causes

  • Failed drainage joints inside walls
  • Pinhole leaks in central heating drainage
  • Rainwater downpipe leaking into a wall cavity
Our process

How we handle leak & fault finding

01
Symptom mapping
Identify the affected area precisely.
02
Non-invasive testing
Acoustic, thermal or dye trace as appropriate.
03
Locate & report
Exact location marked and reported for repair.

Kit we bring

  • Acoustic microphones
  • Thermal imaging cameras
  • Fluorescent dye tracing kits

While you wait — do

  • ✓ Take dated photos of damp patches as they develop
  • ✓ Turn off the leaking service at the isolation valve

Please don't

  • ✕ Don't ignore a leak — it always gets worse and rots timbers

Common questions

Is dye tracing safe indoors?▾
Yes — we use non-toxic UV dyes designed for indoor use.
