Hi all help please,
I'm going to attempt to replace an old wooden window, I've measured outside from brick to brick across top middle and bottom and from the lintel to the bottom of the sill, I've been told to take the shortest of each of those measurements and then deduct 10 mm, is all of that correct please? I'm a little unsure about the sill on the the new window, I've taken a couple of pics to show what I'm replacing, any advice greatly received
