Awake at 4 am, I heard a steady dripping noise. I investigated and found it to be rain leaking in through the window. From the bottom corner, where the plaster around the frame joins the inside sill.
It's a upvc window, probably quite old. It's more of a steady trickle, than an occasional drip, so someone needs to fix this, but who? I'm skint, I can't afford multiple call outs to find out who I should pay to fix it! I know nothing at all about tbis sort of thing, help me!
I can't face looking at it again, so I've drawn a picture. Water is coming in through the red scribbly bit.
