Sealing Gutters

[Fergieman]

Got a valley gutter leaking at the joints. Its a galvanised tin gutter that is dripping at the joints.

Is there something to paint on the inside of the joints to seal them up or is it a case of slackening the joints of and resealing then between the joints?

Flashband

We've painted a few of ours with bitumen paint and it seems to cure them.

Not paint but always seems to be recommended.

For just joints I think sharman stuff is overkill.

Primer and flashband will do a good job for about £20. Promise you.
Fibreglass also a possibility but not sure it sticks to tin?

+1 for fiberglass. Got some leaky valley gutter done 5 years ago and they are still sound, so I had a go at doing some myself this year. Pretty easy to do and seemed to stick to the tin really well.
