How much to repair a leaking gutter joint?

One of the joints on our guttering has started dripping during rain. Is this a cheap fix, or is it worth replacing the whole section? It's accessible from a ladder

"I presume the leak is where the pvc gutter is connected to a fitting.
The cheapest way is to clean around the joint then seal with aquaseal mastic.
The long term solution is t9 remove a section of gutter on one side of the fitting then replace the fitting with a new one then reconnect the section of gutter,either way is quite simple.

Kind regards

"If it’s plastic may just need new rubber seal £100
If it cast it may need more than just a seal on a joint as they will be movement in them as I try to reseal one which would lead to reselling al the joints"
