Crack help

marcarm

I have stripped the lining paper in my kitchen which as been sitting there for 10 years plus.

Above one of the windows I found this crack.

The whole lot below moves, you can push it into place but obviously it falls down again.

Any ideas on what can be done to repair it?

I wanted to replace the paper but this has set me back finding that. I will say that there was a leak from the shower which is above this part of the house, so not sure if the water ingress has contributed to that.

Is it plasterboard?

I wouldn't know tbh, I'm good at the decorating just not the other stuff yet!

You might be able to fix it by injecting some PVA into the crack then pushing it up and wedging it into place with a plank underneath it until it hardens.

Otherwise if the plasterboard has lost its rigidity because of dampness it'll need to be hacked off and replaced with a new piece cut to size and fixed into position.

Thank you, I have a handyman coming to look at it, hopefully soon as I am on a schedule this week and this has set me back :-X

What does that look like outside?

It looks like the upper part of the reveal is bowing, meaning a lack of support above the window.

But then that big patch also looks like it could be a lintel and the crack is straight above that bow.

Bit contradictory. I'd like to see outside.

The photo from inside seems to show the centre top of the window deflecting down. If that's the case it would suggest that whatever is above is not properly supported. The whole area, inside and out, looks like a bodge up. Unless you know a competent DIYer I would get somebody in to check it out.

I'd go for a fairly new build using Catnic type lintels finished off with dot'n'dab plasterboard. In which case, the plasterboard has turned to mush from the leaking shower and needs replacing. PVA won't do anything as it lacks sufficient gap filling properties - A thinned down water based grab adhesive might work, but I've found it hit & miss with plasterboard. Expanding foam (known as "Bodger's Foam" for a reason) squirted in and then bracing the plaster would work - Definite bodge.

Looking at the external photo it could be a concrete boot lintel which only had the bearing on the inner skin. These lintels were quite common in the 60's, but some of them have had a few issues.

sagging plasterboard from leak(complete with 5 screws), remove plasterboard from top of window reveal and replace.
