My landlord is beyond incompetent. She shares the freehold with a few others, and sometimes she exercises her right to get the common parts maintained. She lives in Paris and never inspects the work or meets the contractors. She gets 3 quotes, chooses the cheapest one, and that's it, she's done her duty. Then she falls out with the contractor, argues about the bill and they disappear, leaving all kinds of horrors.
When I moved in the kitchen wall had a pair of 1 ft square holes in it. The kitchen had been fitted over the holes. You can't see the holes from any vantage points outside the building. It took me years to work out where the draught was coming from. I never suspected enormous holes in the outside wall. No wonder there's a giant crack in the building and all the flats below are damp. By then I'd discovered that getting her to fix things would only make them worse, so I just filled half the fucking kitchen with expanding foam.
We had all the repointing and window frames done. I sent her photos of the worst bits, but she fell out with the contractor before they got to the very worst bit, the north facing walls at the top, i.e. my flat. Some of my window frames are now mostly filler, the rest still have that nasty dark green paint which nobody's used since the '50s. The mortar between the inner and outer brick courses has chunks missing. The bathroom's sash window has to be opened very gingerly in case the glass falls out. I could go on. She even managed to pay the £30k bill to a push payment fraudster who hacked her email. After that she gave me notice and put the flat on the market on some shitty self-service property site where she wrote the blurb, describing the flat (2 beds on Rushcroft Road) as a penthouse, worth £925k. That didn't work, so we agreed a small rent increase in exchange for me continuing to live here.
