Added this to gardening and was advised to post here.

I got my greenhouse and didn’t account for the sloping away of the wall it was to go against. Meaning a small gap at the bottom becomes 4” at the top. I can’t push it into the wall as it warps the greenhouse and can’t leave the huge gap. Is there a way of deal with this?

I was thinking of maybe - some type of structure around it then fill with expanding foam then remove the structure. - some mesh then plaster it


Make a wood frame with the required taper.

This may also help with sealing to the surface of the wall.

  • Probably should have mentioned it’s an old stone wall so it’s not even, very bumpy

    Well you can take a plank and mark the shape of the wall on it and cut to fit - will make the sealing much easier.

  • Just realised I never accepted this, a wedge shaped piece of treated wood and some foam filler for the remaining holes did the trick. Thanks.
