What would cause cracks to appear on every ceiling in my house?

Anonymous user 03/03/2024 - 3.05 PM

I have lived in my bungalow for 7 yrs now and over the last 12 months or so I have started to notice hairline cracks running the length of my ceilings, they appear to be where the joins are in the plasterboards. I'm a little concerned as to why they have appeared so suddenly, I also have a length of coving on one of my bedroom ceilings that is coming away from the wall and has left a 5mm gap. I dont know whether this has any bearing at all but, I had loft insulation done last year, also a new boiler, and cavity wall insulation so I had tradesmen working in the roofspace/loft on several occasions, someone also said that the heat and humidity from last summer could have had something to do with these cracks too? Also, in my bedroom, I keep hearing a 'clunking' noise coming from the outer wall behind my bed, it sounds like a rubber mallet hitting the brickwork and it pretty loud! As I said, I have lived here for seven years and I have not noticed this noise before, however, I have been really ill over the last year and have spent a lot more time in my bedroom than I would normally do, I am worried that the ceiling cracks coupled with the coving gap and the clunking noise are warnings that the house is going to fall on me, I really need some advice please. Thank you.
