A property in Costa Blanca that remains unoccupied for several weeks or months can develop problems that are not immediately obvious.

From a small water leak to humidity, condensation or air-conditioning issues, early identification can make an important difference.

1. Check access and security

The first step is to check the access points:

  • the main door;
  • windows;
  • shutters;
  • locks;
  • the terrace and exterior access, where applicable.

Any change compared with the previous visit should be documented.

2. Water and plumbing

A minor water issue can become a serious problem if the property remains unattended.

It is useful to check periodically:

  • taps;
  • toilets;
  • areas under sinks;
  • any signs of water ingress or leaks;
  • water meters.

3. Humidity and the indoor environment

In a coastal climate, humidity should be monitored over time.

A single reading does not always tell us very much. It is therefore more useful to compare readings between visits and follow the trends.

Prevention starts with noticing changes before they become costly problems.

4. Ventilating the property

Periodic ventilation can help reduce stagnant air and condensation.

Depending on the property, this can be complemented by monitoring temperature and relative humidity.

5. Document every visit

Photographs and observations create a history of the property.

At Stay in Costa Blanca we use a simple method:

Measure → Compare → Document → Detect → Act.

Conclusion

Preventive property management is not simply about checking whether “everything looks fine”.

It means monitoring the property over time and identifying changes before they become bigger problems.
