Bifold Door Installation. Watch this before you buy.
I have fitted a fair number of Quickslide sliding sash windows over the years but this was my first job using their Bi-fold doors.
I attended a trade show to check out the quality before I ordered them and was very impressed by the build quality and the way they operated. The unknown quantity, for me, was the fitting. Happily it turned out to be one of those rare occasions where the job was much easier than I anticipated.
