Signs of a hidden water leak in Benissa or Moraira
Hidden leaks are not always visible straight away. In villas, apartments, rental homes and commercial properties around Benissa and Moraira, the first signs may be subtle.
You may have a hidden leak if you notice:
- Damp patches on walls, ceilings or floors.
- Peeling paint, bubbling plaster or damaged wallpaper.
- Mould, mildew or dark staining.
- A musty smell that does not go away.
- Loose tiles, cracked grout or damaged silicone.
- Swollen flooring, skirting boards or door frames.
- Reduced water pressure.
- A boiler or water heater losing pressure.
- The sound of running water when taps are off.
- Higher-than-usual water bills.
- Wet areas outside the property with no clear cause.
If you see these signs, avoid opening walls, lifting floors or breaking tiles without professional advice. A plumber can help assess the likely source and recommend the safest repair.
Why hidden leaks should be repaired quickly
A hidden water leak may start small, but the damage can spread through walls, floors and ceilings. Water trapped behind surfaces can affect plaster, flooring, cabinets, insulation, tiles and electrical areas.
In Costa Blanca properties, hidden leaks may also be linked to older pipework, pressure changes, limescale build-up, hot water systems or outdoor pipework exposed to weather and movement. If the underlying cause is not repaired properly, the same problem can return.
100% Plumbing provides general plumbing services for water leaks, pipework problems, pressure issues and plumbing repairs. If the leak is connected to a cylinder, boiler or hot water system, you can also read more about our hot water systems and repairs.
What should you do if you suspect a hidden leak?
If you suspect a hidden water leak in Benissa or Moraira, act early. Waiting can increase damage and repair costs, especially if the leak is affecting walls, floors, ceilings or electrical areas.
You should:
- Turn off the water supply if the leak is active or spreading.
- Avoid using sockets or appliances near damp areas.
- Check whether the water meter moves when all taps are off.
- Take photos of damp patches, stains or visible damage.
- Move furniture and valuables away from affected areas.
- Avoid painting over damp or mould before fixing the cause.
- Contact a professional plumber for inspection and repair advice.
If the leak is spreading quickly, dripping through a ceiling, close to electrics or causing flooding, treat it as urgent. In that case, call 100% Plumbing’s 24h emergency help line on 607 415 520 or visit our emergency plumbing page.
