You may have a hidden water leak behind walls or floors in your Calpe home if you notice damp patches, peeling paint, swollen flooring, loose tiles, mould, musty smells, unexplained stains, reduced water pressure or a higher-than-usual water bill.
Hidden leaks can develop slowly behind bathrooms, kitchens, utility rooms, ceilings, terraces or pipework areas. Even if the leak is not visible, the damage can spread through walls, floors and ceilings if it is not checked and repaired early.

Signos comunes de una fuga de agua oculta
Hidden water leaks are not always obvious at first. In many Calpe and Costa Blanca properties, the first sign may be a small damp patch, a musty smell or a change in water pressure.
You may have a hidden leak if you notice:
- Damp patches on walls, ceilings or floors.
- Peeling paint, bubbling plaster or damaged wallpaper.
- Swollen wooden flooring, skirting boards or door frames.
- Loose tiles, cracked grout or damaged silicone seals.
- Mould growth or dark stains.
- A musty smell that does not go away.
- The sound of running or dripping water when taps are off.
- Reduced water pressure.
- A boiler or water heater losing pressure repeatedly.
- An unexplained increase in your water bill.
- Wet areas outside the property with no clear cause.
If one or more of these signs appears, it is best to arrange a professional inspection before opening walls, floors or ceilings yourself.
Why hidden leaks should not be ignored
A hidden leak may look minor on the surface, but water can travel behind tiles, under flooring or through ceiling voids. Over time, this can damage plaster, cabinets, flooring, insulation, paintwork and electrical areas.
In homes across Calpe, hidden leaks may also be linked to older pipework, pressure changes, hot water systems or limescale build-up. If the cause is not repaired properly, the same issue can return and lead to higher repair costs.
If the problem appears to be connected to hot water, a leaking cylinder, a boiler or repeated pressure loss, you can also read more about our sistemas de agua caliente y reparaciones.
