Where we started
The brief
Joe's home in Richmond has a walled courtyard garden behind large glazed doors, almost entirely covered by an old timber deck. The boards had weathered and the frame underneath had rotted.
Rather than patch it, the whole deck and frame needed to come out and be replaced with something that would not rot again. Composite boards on a new frame were the answer. It is a good example of the decking in Richmond we build.

Questions
About replacing timber decking with composite
Thinking about something similar? These are the questions we hear most.
How much does Trex composite decking cost in Richmond?
Joe's courtyard deck in Richmond TW9 cost £4,000 including VAT and took two days, covering removal of the old timber deck and its rotten frame, a new timber frame, and Trex composite decking supplied and fitted. Size and the board range make the biggest difference.
Can you put composite boards on my old deck frame?
Only if the frame is sound. Joe's frame had rotted, so we removed it and built a new one. Putting new boards on a rotten frame just moves the problem out of sight.
Why replace timber decking with composite?
Composite does not rot, splinter or need staining, so it stays looking good with just an occasional clean, while timber needs regular upkeep and eventually rots.
Is Trex good composite decking?
Trex is one of the best-known composite decking brands. The boards are made largely from recycled materials, resist rot, fading and staining, and need far less upkeep than timber.
How long does it take to replace a deck with composite?
Joe's courtyard deck took two days, including taking out the old deck and frame, building the new frame and laying the Trex boards.
Do you take the old deck away?
Yes. We removed Joe's old timber deck and its frame as part of the job.
Do you fit composite decking near Richmond?
Yes, including Twickenham, Kingston and Putney. See all our landscaping in Richmond.
