I'm totally clueless so any advice would be very much appreciated.
We have a freezing, damp crappy bathroom with an ancient metal-framed window that needs replacing. It's an odd size so we will need a smaller one, meaning that some building work will be necessary. Do window companies (Everest etc) do that, or will I need to buy a window and get a builder to put it in?
Am I right to think that we should sort the window out first, and then install the new bathroom?
