Selecting the Right Wood for Your Outdoor Pergola

When you have decided that a pergola is the right option for your garden, the next big decision is what wood to choose. There are lots of different options in both hardwood and softwood categories that all bring different looks and benefits to the end result. Here are some of the most popular to help you choose the best wood for your outdoor pergola.

Pressure treated timber

A strong, affordable and low-maintenance option for budget-friendly pergolas.

Pressure treated timber is placed under a vacuum so preservatives can penetrate deeply into the wood. Modern regulations ensure environmental safety. This timber is strong, resistant to fungal decay and insects, low-maintenance, and budget-friendly. It also comes in a variety of types and grades to suit different price ranges.

Oak

Oak has been used in construction for centuries thanks to its long-lasting strength and natural beauty. Oak pergolas weather beautifully, each with its own distinct grain and character.

Oak pergola kits are made from green oak—one of the toughest, most durable timbers available. Highly moisture-resistant and sustainable, green oak locks in the CO₂ it has absorbed over its lifetime.

Western Red Cedar

Western Red Cedar is naturally resistant to rot, insects, and harsh weather. It has a rich amber colour that fades to a silvery grey if left untreated—but can also be stained or painted. Its rustic aesthetic makes it a popular choice for decorative pergolas.

Douglas Fir

Douglas Fir—especially the North American varieties—is extremely strong and resistant to stress. It handles extreme weather well, and unlike some softwoods, does not warp or shrink easily. Attractive and reliable, it offers both durability and style.

Larch

Larch is a durable UK-grown softwood that is more affordable than many hardwood options. It has natural insect resistance and a warm golden colour. While not ideal for heavy structural construction, it is excellent for lighter outdoor structures like pergolas.

Choosing the right wood for an outdoor pergola

There’s no right or wrong choice—your ideal pergola wood depends on durability needs, maintenance preferences, budget and the look you want to achieve.
