Crack in wall
Hi, im really worried about a crack in my wall. I’ve spoken to a couple of builders and sent them these photos but they are so busy at the moment. my anxiety is through the roof waiting for one of them to have time to come and look.
I’ve got what’s looks like a 1mm slightly diagonal 1.5 meter long crack in my internal plaster. it’s covered by wallpaper at the moment. It easily shows during the day in the warmer weather by creasing the wallpaper then mostly goes in the evening when it’s cooler outside. Its an upstairs, gable end cavity wall south facing so gets the sun all day. It starts roughly at the bottom of a windowsill up towards a chimney breast and looks like it follows up the side of the chimney a little. I’ve take the plaster off in a couple of places (about an inch) and it looks like there’s a gap between the bricks where the mortar is missing/failed.
The bottom of the crack steps out a tiny bit but I think the plaster has blown. it’s original 1950s, very thick and sounds hollow in places.
we had a much shorter similar crack looked at by a structural engineer a few months ago and he said that was due to old plaster and the heat. I feel like a really wasted his time and he was lovely so feel reluctant to call him again so soon
Theres also a 1mm horizontal crack at the top of the window that’s been there 4 years at least, though when looking at it today it could be a bit longer than it was. window opens fine, there’s no cracks showing outside
