The apartment was in perfect condition b4 the damage. He lent me a de-humidifier, I left it on for a week, it caused cracks in other places as a result. We agreed to paint the walls and ceiling only where the water damage was but the marks came though as clear as they were before the painting. The result was they needed to be primed and painted over 3 times, its was big inconvenience. The paint work was only done where the water damage was visible, as a result is not perfect. He doesn’t want to pay for the work done. He wants an invoice. It’s my first time experiencing such things, and I'm learning a lot by it. Question is - legally do I have to consult him before I got the professionals in. I would like it to be amicable, I’m a reasonable person, but unfortunately its got a bit nasty now. The bottom line is, the apartment was perfect before now, and I don’t think I should be out of pocket to get it back to the condition it was in before hand. Thanks for all your input!
