Hi Tosh
its not a newish house, but from the ground it looks like there are three seperate pains of glass in all the windows,
but like I said, in reality it is Just one pain of glass, these strips are stuck or pinned to the side rails of the frame or even mortised into the side frame, over the years these bars have warped and on some you can put your fingers behind these bars (made of the same wood by the way) some are still tight against the glass, if I wash with an applicator water just seeps behind these wooden bars and takes ages for it all to come out, this was my worry for WF, this guy is fussy but a very good customer, I would sooner do it with WF but if the water takes ages to finish seeping from behind the bars I'm worried it will carry any dirt down the windows.
I was wondering if this one would best be kept Traditional?
