crack under window

[boxtree]

Hi,

I've recently been decorating and removed wallpaper to find this deep crack under the window. I've looked out of the window and the brickwork looks fine with no cracks or gaps in the mortar.

The wall has no other cracks, not even hairline. The house was built in 1968 and the double glazing was added around 15 years ago.

Another point which may or not be related is that there are 4 random wall plugs that have been left in the wall, not sure if this could be a potential cause?

Can anyone advise if it is ok to just fill this with regular pollyfilla? Or is something more advanced required?

Thanks,

Just rake out the loose plaster and fill with polyfilla, you will probably need a second fill once its dried out.

Could be that there was a Storage Heater fitted under the window.

Great, thanks.

Just wanted to check as i've never seen a crack this deep before and was worried a specialised might have been needed.
