How to replace a fence post

One of our timber fence posts has rotted at the base. I'm trying to work out if it's worth doing myself or if it's easier to get someone in. What tools and materials would I need to do this job?

"You would need some kind of breaker to get the concrete out from the under the soil and dig out by hand. Would need a new post and 2 bags of post fix just to be sure and a level"

"Hi Kelly,

You buy a concrete spur and bolt it to the wooden post. You will need a beaker and spade to do the job. I hope this helps.

Thanks
Mark"

"If the post has rotten and the replacement post of going into exactly the same place, it can be quite tricky to remove what's left of the old post in the ground.

Tool wise you'll just need post diggers and a spirit level to put a new post in, to remove old post which is likely set in the ground in concrete your looking at hiring a breaker to remove it.

Personally hiring someone to replace one post won't be that much, personally I'd charge no more than £80 for that"

"Dig out one side of the concrete and pull the damaged post into the hole this saves digging out the four sides, once loose remove post without making a huge hole with loose sides, sit post in hole and backfill underneath to set your height. Then level and secure in upright level position. Fill hole 2 thirds with water and add post mix, not foam until the hole is full."

"Hi,I hope you are ok!
take the post out, you have to break the supporting cement or take it out directly if possible.
clean around the post and make a hole to put cement and fix the new post.
you need a level to put it straight and a tape measure to use to be at the same distance as the others next to it (left, right), otherwise it is possible that when you put the panel it will not be ok if it is not at the distance that it should be ...
everything being measured correctly, there will be no problems when you put the panel"

"Hiya, It’s a doable DIY job but getting the old post and its concrete base out is the hard part (in my opinion). You’ll need a spade, crowbar, club hammer, a new treated timber post, and either a bag of Postcrete or a concrete repair spur if the rest of the post is still solid.

If it’s just rotten at the bottom you might get away with bolting a concrete spur to it rather than a full replacement- saves a lot of digging!"
