Composite decking cost (installed)? | Mumsnet
25 · Anyone had composite decking installed recently? If so, can I ask how much it cost? We are looking to have about 40m2 of raised decking replaced (we think that the structure is ok - so just the boards, fixings, fascia and edging etc). Then we would be adding about about 20m2 (along a new extension) to “step down to” the garden level.
