How much does decking repair cost?

Question

few of the boards have gone soft and one of the joists underneath looks rotten. is it worth repairing or better to replace the whole thing, its about 4m x 3m?

Daniel · Accepted Answer

It's very hard to cost. Can be repaired but for what it's worth if it's starting rotten my guess is that's very old so if the budget there I would personally replace

Evan · Answer

I would replace the whole thing, if them boards have gone rotten then the underside where the structure of it is will be rotting to

Lucas · Answer

In my personal opinion I would replace it all. If one joist is already rotten then no doubt the others won’t be far behind. This price for brand new would be done on one price as a whole.

For a 4m x 3m deck, if only a few boards and one joist are rotten, repairing it would normally be more economical than replacing the whole deck. A typical repair could be around £300–£700 depending on access and the extent of the rot. If several joists are affected or the subframe is generally deteriorated, full replacement may be better value, typically around £1,500–£3,000 depending on the timber or composite decking chosen. The structure should be inspected first, as rot can sometimes extend further than is visible from above.

Hi.
I would need to have a look at it to see to what needs to be repaired. Also please bear in minded you might not be able to get the same decking boards to match the old ones.
Many thanks.

Can be fixed depending on the surrounding timber condition. May be worth completely replacing if the existing decking is very old.

For a 4m x 3m deck, I’d recommend checking the joists and the full frame before deciding whether to repair or replace it. If only a few boards and one joist are rotten, a repair could be much cheaper than replacing the whole deck.

As a rough guide, replacing a few boards and repairing the affected joist could be around £300–£600, depending on access and materials. A full replacement could be considerably more. Getting it inspected first is the best way to know which option represents better value.
