Fascias, Soffits & Guttering

My cast iron guttering has a leak. replace or fix leak.

My cast iron gutter has a leak. Would it be easy to fix? I’ve had a roofer use a sealant before, but the leak has come back. I think the leak is in the joint. The other issue is that the gutter is connected to my neighbours roof, which I can see would be an issue.

Thanks for all the replies, certainly educated me.

Keep the peace between neighbours.
Yes, the joint can be cleaned and re-sealed this should solve the problem.
However, if there is a hairline crack in the joint this may have to be replaced.

Never been of fan of using sealants especially in an external situation like roof line products or roofing . I would always recommend repaclement , anything else would be a short term repair

I’m recommending to change the iron gutters to the plastic with proper levels and underly support trays :)

If the gutter has a hairline crack you can use a paint or spray sealant to seal it as the joint just needs a clean and a mastic applied.
