If you are worried about a hidden leak, the most important step is booking a professional inspection. Preparation does not replace the visit, but it helps the specialist understand the property quickly and check the right areas first.
Before the visit
Write down what changed. Note when you first noticed the symptom, whether it appears after rain, after shower use, when the pump runs, or when the water meter moves.
Keep access clear. Tanks, manifolds, bathrooms, shafts, terraces, garages, utility rooms and affected walls may need to be checked. Clear access saves time during the inspection.
Know who needs the answer. Tell us if the findings are for you, a landlord, a neighbour, a property administrator, a plumber, an insurer or WSC-related follow-up.
Make water and electricity safely available where needed. Some checks depend on water supply, hot water use, pumps or access to fixtures. If anything is unsafe, tell us before the visit.
Secure pets and sensitive areas. The inspection may involve movement through the property, equipment and opening access panels.
What not to do
Do not open tiles, seal random joints or repaint damp areas before the inspection unless emergency safety requires it. Covering evidence too early can make the source harder to understand.
Do not rely on assumptions to diagnose the leak. The reassurance comes from having the property checked properly.
Book the inspection
If you have a high bill, moving meter, ceiling stain, bathroom leak, damp bedroom or water entering from above, book a professional leak detection inspection and let the evidence guide the next step.
