Argh. Yeah look tbh I did the same at my old place - when I got the blinds replaced as the old one literally was going to fall off, bam, rent increase (even though it’s improving the sale price of the house and tax deductible! Fuckers)

I did have to give in and ask them to do my old stuck winder though as it was letting in a lot of cold air heading into winter and that sucked big time. I think the LL’s partner just did it himself.

Your situation sounds serious enough to be worth getting fixed…
