About 2 weeks ago water started dripping down from the upstairs apartment. Their boiler went on the blink but they were not there when it happened. It caused a nice bit of damp damage to my ceiling and left the walls covered in mildew. As ownership of the apartment is on a leasehold basis I'm assuming that the Mngt Co. is responsible - Anyone had a similar problem? I spoke with the Mgt Agent who disclaim any responsibility which I accept but then they started mentioning about an excess on the Block Insurance Policy. As far as I am concerned I should not incur any expense, and any excess should be borne possibly by charging the upstairs Landlord or the Mngt Co accepting responsibility. Is this unreasonable?
