One of the main advantages of oak pergolas and outdoor structures is their low maintenance. Oak is naturally durable, so chemical treatment is not essential.
Yes. Untreated oak can last for decades outdoors. As it weathers, the colour changes from golden brown to a natural silver-grey patina. Small surface cracks can also appear as the timber seasons. These are normal and do not necessarily affect the structure.
In coastal areas, stainless steel or galvanised fixings are recommended to help resist corrosion.
Treatment is optional. If you want to keep the original oak colour for longer, a UV-protective exterior oil can slow natural greying. At Timber Solution, our oak structures can be left untreated or finished according to the appearance you prefer.
