Saving a Shed from Damp and Rot That's Next to Neighbours Wall Fillers, sealants and adhesives for all types of DIY work. Help, advice and information on all aspects of this subject

Hi all,

The previous owner of my house built the shed right next to the neighbours brick wall - I guess assuming that it would offer the shed some protection.

However, over the years debris has fallen down the small gap between shed and wall and when it rains the water soaks into the debris and eventually the shed.

There are signs of rotting and there's not really much can do to replace the wood so was considering filling the gap with expanding foam, sanding so its got a bit of a gradient and then topping off with an external sealent.

Does this seem like a crazy idea? I'm open to any suggestions - clearing out the debris is pretty difficult due to access restraints.

I already installed some guttering but that has only partially helped.

Cheers for any advice

Carl

use treated timber to fill the gap and cover it with flashband to seal it

Thanks, hadnt heard of flashband before

the foam method sounds like a good idea,do it in summer though as you dont
want to trap moisture.
