Best practices for preventing dampness in your home

Our tips for preserving your property in the Basque Country

Humidity is one of the most common problems in homes, and the Basque Country is no exception to this reality. Between the oceanic climate, regular precipitation and proximity to the ocean, homes are particularly exposed. If not treated quickly, humidity can lead to mold, material damage, excess energy consumption and even harm indoor air quality.

A few simple actions, carried out regularly, can limit risks and preserve your assets.

1 - Air out your home every day.

Even in winter, it is essential to air out your home for 10 to 15 minutes a day. This habit helps remove moisture generated by cooking, showering, laundry, or simply the occupants' breathing.

Good air circulation significantly reduces the risk of condensation and mold growth.

2 - Check that your mechanical ventilation system is working properly.

Controlled Mechanical Ventilation (CMV) is your best ally against humidity.

Consider:

  • regularly clean the exhaust vents;
  • never obstruct them;
  • Have your system checked if it becomes noisy or seems less efficient.

A well-maintained mechanical ventilation system ensures optimal air renewal throughout the house.

3 - Maintain a stable temperature.

A home that is not adequately heated encourages condensation, particularly on walls and windows.

If you own a holiday home, avoid leaving the property completely unheated for several weeks. Maintaining a minimum temperature helps limit humidity fluctuations and protects your equipment.

4 - Avoid drying laundry indoors.

Drying laundry releases several liters of water into the air.

Whenever possible, opt to dry laundry outdoors. If that is not an option, ventilate the room thoroughly or use a dehumidifier.

5 - Inspect your roof and gutters regularly.

A simple water leak can cause significant damage if not detected quickly.

Make sure to check the following at least twice a year:

  • the condition of your roof;
  • gutters, which can become clogged with leaves or debris;
  • rainwater downpipes.

Proper rainwater drainage is essential to protect your home.

6 - Keep an eye on the joinery.

Windows and doors are vulnerable points.

Check regularly:

  • seals;
  • the tracks of the floor-to-ceiling windows;
  • any signs of water ingress around the openings.

Worn seals can allow moisture to penetrate and increase heat loss.

7 - Have your equipment inspected.

Certain types of equipment can cause excessive humidity:

  • water heater;
  • air conditioning;
  • faucets and fittings;
  • pipes;
  • water drainage outlets.

Regular maintenance helps prevent leaks and extend their lifespan.

8 - Pay close attention to the most exposed areas.

Certain rooms naturally accumulate more moisture:

  • the bathroom;
  • the kitchen;
  • the laundry room;
  • the cellar;
  • the garage.

After showering or preparing meals, remember to ventilate these areas to quickly clear away water vapor.

 

 

9 - Spot the early signs of dampness.

The earlier an anomaly is detected, the less extensive the repairs will be.

Pay attention to:

  • a musty smell;
  • black spots in the corners;
  • peeling paint;
  • peeling wallpaper;
  • persistent condensation on the windows;
  • water stains on the ceilings or walls.

These signals must never be ignored.

Why are these gestures particularly important in the Basque Country?

The Basque climate is pleasant, but it puts homes to the test. Frequent rain, high humidity, and sea air accelerate the deterioration of materials if houses are not regularly maintained. Depending on their location—such as in Biarritz, Anglet, Saint-Jean-de-Luz, or Bidart—some homes are more affected by this climate than others.

A few preventive checks are often enough to avoid major repairs and preserve the long-term value of your property.
