Terraced Housing - Different Gutter to Neighbour Join Issue

[andre1990]

Hi all,

Just moved into a new house and there’s bad damp and swelling downstairs caused by a faulty join between my gutter with neighbours.

I have square guttering, as do most of the street, and as do the ones the other side of my neighbour, but my neighbour has ogee.

The union appears to have been put on my side of the boundary. I don’t know when any of this work was done.

I’ve had a few roofers come and look at it and they’ve suggested a few things:

1) Sealant and retry, which I’m not keen on as it will fail again
2) Downpipe at that join
3) asking neighbour to change to square gutter to fit in with everyone else
4) Cap an end off, which I must admit I don’t fully understand.

Does anyone have any thoughts or experience with this type of situation?

Common problem. Gutter moves with heat so normal joins allowed for sliding without seal breaking.
Really want the same gutter all the way along and be maintained so water runs out. Unfortunately that's never the case.

Silicone or polymer sealant is only a temporary fix

Would a downpipe work well?

You can fit a hopper to downpipe.
With a hopper one type of gutter brand either side as it eliminates the join
