Polyurea, Spray Foam or Bitumen Membrane? Choosing the Best Roof Insulation
A practical comparison of the most common roof insulation systems: polyurea, polyurethane spray foam and bituminous membranes…
The most dangerous leaks are the ones you cannot see. Water can leak for months inside walls or under floors before any clear sign appears, damaging concrete and finishes and driving up your bill. Here are the signs you should never ignore.
1. A sudden rise in your water bill
If the bill goes up while your household usage has not changed, it is the first and clearest sign of a leak, especially in buried pipes or the underground tank.
2. The meter moves with all taps closed
Close every tap and appliance and watch the meter. Any movement means water is going somewhere.
Quick test: note the meter reading at night and use no water until morning. If the reading changed, there is a leak.
3. Damp stains on ceilings or walls
Dark or yellow stains on the ceiling below bathrooms and kitchens, or on walls near pipes, usually point to a leak from above or inside the wall.
4. Peeling paint and white salts
Bubbling, peeling paint or a white layer of salts on a wall means moisture has reached inside the masonry.
5. The sound of running water
In the quiet of the night, if you hear water running inside walls or under the floor with taps closed, there is probably a pipe leak.
6. A persistent musty smell
A smell that stays despite ventilation and cleaning can mean hidden damp behind cabinets or under floors.
7. Changes in tiles or floors
Lifting or loose tiles, discolored grout or a damp feeling underfoot can all indicate a leak below.
How is a leak found without breaking?
Instead of breaking at random, a specialist uses electronic devices to pinpoint the leak:
| Device | What it does |
|---|---|
| Acoustic listening devices | Pick up the sound of water escaping from buried pipes |
| Thermal camera | Reveals temperature differences caused by moisture behind walls |
| Moisture meters | Measure moisture levels in walls and floors |
| Pressure testing | Shows which water line is losing pressure |
Once found, only the leak spot is opened and repaired, then the line is tested to confirm the problem is solved.
Every day a leak goes unrepaired means more wasted water and more damage. Acting early is always cheaper.

Frequently asked questions
How can I test for a leak myself?
Turn off every tap and appliance that uses water, then watch the water meter for a while. If it moves, there is most likely a leak somewhere.
Does a water leak damage the building?
Yes. A constant leak reaches the concrete and steel reinforcement, causing rust and cracks, as well as mold and damaged finishes.
How long does leak detection take?
It depends on the building size and the number of suspected points; usually it is done in a single visit.
