Hardwood Timber Decking FAQs
Hardwood joists are structural timbers cut from dense, slow-growing trees. They are used to create the subframe or foundation for outdoor structures like decking. Their natural density and strength make them an exceptionally strong and durable choice for a high-quality, long-lasting build.
The key benefits are superior strength and natural durability. Hardwood joists are significantly stronger and more resistant to rot, decay, and insect attack than treated softwood. This means they provide a more robust, stable, and longer-lasting foundation for your decking project.
A professionally installed hardwood subframe is built to last for decades. Depending on the specific type of hardwood used and the ground conditions, you can expect a lifespan of 25-40 years or more, often outlasting the decking boards placed on top.
Yes, they are an excellent choice for the UK. Many hardwoods have a high natural oil content and a dense grain structure that makes them inherently resistant to moisture absorption and rot, ensuring they perform exceptionally well in damp environments.
While hardwoods are very durable, we always recommend that any timber subframe is raised off the ground. Our professional installation ensures the subframe rests on appropriate supports, like concrete pads, allowing for proper air circulation and preventing constant contact with wet ground.
Absolutely. A hardwood subframe provides a premium, stable, and long-lasting foundation that is perfectly suited for supporting high-quality composite or PVC decking boards. Using a hardwood frame ensures the base of your deck will last as long as the high-performance boards on top.
Due to their density and weight, hardwood joists require more effort and specialised tools to cut and fix compared to softwood. Our experienced installation team has the expertise and equipment to work with these premium materials, ensuring a precise and secure construction.
They are ideal for high-end projects where longevity and strength are paramount. This includes premium decking areas, raised platforms, walkways over uneven ground, and any structure that needs to support significant weight or withstand challenging conditions.
Most high-quality hardwoods used for structural purposes have excellent natural resistance to decay and do not strictly require chemical treatment. However, applying an end-grain sealer during installation can provide additional protection and further enhance their lifespan.
Once installed correctly, the subframe itself requires virtually no maintenance. The primary focus of maintenance will be on the decking surface above. The 'fit and forget' nature of a hardwood frame is one of its key advantages.
Both are premium, long-lasting options. Hardwood is a natural, traditional material renowned for its incredible strength. Recycled plastic is completely immune to rot and can be laid on the ground, but hardwood often offers greater structural rigidity and load-bearing capacity, making it ideal for complex or elevated structures.
All timber has the potential to move. However, by sourcing high-quality, properly seasoned hardwood and using expert installation techniques, the risk of significant warping or twisting is minimised. The density of hardwood makes it inherently more stable than softwood.
Yes, the initial investment for a hardwood subframe is higher than for standard treated softwood. This cost reflects their superior strength, quality, and significantly longer lifespan.
Definitely. While the upfront cost is higher, a hardwood subframe represents excellent long-term value. You are investing in a foundation that will not need replacing for many decades, preventing the costly and disruptive process of having to rebuild a failed softwood frame in the future.
When sourced responsibly, yes. At Outdoor Makeover Group, we ensure our hardwoods come from legal, certified, and sustainable forests. Using a durable, natural material that lasts for decades is a sustainable approach to construction.
