About a year ago or more, it was a very windy night and I had left the downstairs shower door ajar to air the room. I left the house and on my retu I discovered the glass in the shower door was shattered all over the floor and the only way it could have happened is when I left the house, the wind blew through and consequently the door hit the radiator which had an airer on it, therefore causing the glass to break. I informed the landlord via a third party and he apparently said he didn’t see why he should replace the glass in the door. I have looked for the door online to replace and the nearest one to it I can find is a bit expensive for me to buy. I would appreciate any advice please.
