How to fix rotten timber pool surround?

Hi, I need to redo my pool surround and copping BC the timer has been eaten by an orange fungi, and the nails are popping up.

It's dangerous to walk around. As it was only done 7 years ago I'm after the most economical solution. The pool measures 4x5 mts, the decking is not huge. Please see attached photos.

Hi @LE2,

Welcome to the Bunnings Workshop community. We're so pleased to have you join us.

Seven years seems an exceptionally short lifespan for any deck so I'm hopeful that the damage is not terribly serious. It's certainly common for screws or nails to pop up as the timber moves, so that is a common maintenance job to screw and/or nail them down again. It also looks like your deck would benefit from sanding and oiling like in my own deck renewal project.

What would be much more concerning from a safety point of view is rotting timber. Is there any evidence of that? The guide How to renovate a timber deck by @Adam_W would be a great place to start for what might be involved if the damage was more serious.

If you were looking to totally replace the deck, Adam also provides great inspiration with his poolside timber-free deck with steel frame.

Please have a thorough inspection of the deck and let us know if there is any concerning damage. We are very happy to answer any follow-up questions you might have regarding next steps. We're here to help.

Hi @LE2,

I'd encourage you to have a few quotes done on a restoration of the deck rather than a replacement. If the deck can be saved, then I think it's worth going that route, as the Merbau decking should still be in a reasonable state, just requiring a sanding.

The popped screws are a little concerning, and I suspect there might be something going on with the timber which has been used for the structure and joists, and perhaps it has rotted. When you say the deck was done seven years ago, was that new decking laid over an existing frame from a previous deck? If it was just new decking over an old frame, I presume that the frame, which might have been reasonably seven years ago, has now rotted.

Please let me know if you have any questions.
