On average, a timber subframe
lasts approximately 8-10 years.
We found that the average timber subframe lasts approximately 8-10 years. So, you can understand why we are often baffled when customers of ours opt to install our long-life composite decking (which comes with a 25-year warranty) onto this subframe solution. We promote the benefits of using our moisture-resistant composite and recycled plastic subframe options, instead.
That being said, we understand that this is a solution widely used by customers due to the relative cost-savings that can be made in the short-term. While there is not a lot that can be done to fully prevent the inevitable damaging effects of moisture on your timber joists, we have outlined 6 top tips you can follow to prolong these effects- meaning your timber subframe will remain safe and stable for longer.
