Outdoor wooden structures—whether in porches, pergolas, decks, or facades—provide warmth, beauty, and natural integration with the environment. But with the arrival of summer, intense sun, high temperatures, and low humidity can affect the durability and appearance of these elements if proper maintenance is not done.
At Pallars Fustes, as specialists in wood construction and structural engineering, we share some tips to ensure that your outdoor wooden structures remain in perfect condition and continue to be a sustainable and long-lasting bet.

1. Protects wood from sun and extreme heat
UV rays can dry out and degrade the surface of the wood over time. We recommend applying natural oils or sun-protective stains specifically for exterior use. Unlike paints, these products allow the wood to breathe and maintain its natural appearance.
2. Monitor humidity and condensation
Even if the summer is dry, occasional rain or environmental humidity can affect the wood if it is not well ventilated. Avoid direct contact with accumulated water and make sure there is good ventilation between the structure and the ground to avoid condensation and internal humidity.

3. Regular and gentle cleaning
A surface cleaning every so often helps to eliminate dust, fungi or mold that can appear with heat and humidity. Use warm water and neutral soap, avoiding abrasive products that could damage the surface treatment of the wood.
4. Review and revise treatments annually
Summer is a good time to do a visual inspection and detect cracks, discolored areas or small deformations. Depending on the exposure and type of wood, it may be necessary to reapply a protective treatment every 1 or 2 years.
5. Choose quality and sustainable woods
If you are thinking of building a new structure, choose wood prepared for the exterior such as treated spruce, larch, or heat-treated wood. At Pallars Fustes we work with certified wood and materials designed to withstand the most demanding conditions in a sustainable way.
Building with wood is not only an aesthetic and warm option, but also one of the most sustainable. But like any natural material, it needs proper maintenance to preserve all its properties.
With these simple tips you will be able to enjoy your wooden structure outdoors for many years. And if you have any questions or need technical advice, at Pallars Fustes we are by your side to turn your projects into reality.
