Once the guttering has been subject to uv degradation and embrittlement,
changing the seals can be a problem (if you can get them). OTOH if they are
not leaking now, leave well alone until they are - if they do leak it will
start very slowly (drips). You can always pop some mastic in them, get a few
more years out of them and then change them. I suspect you are
over-worrying!

From someone who does have the odd joint in plastic guttering that is
dripping slightly, what is the best way of applying some mastic.
Obviously a bit of cleaning up but do I need to spring the joint and
get the mastic into the joint ?

Thanks
