Duration Windows

I purchased bi-fold aluminium doors combined with traffic door to my special design and measurements. I had previously enquired with several other companies who told me it could not be done. I specifically wanted aluminium because of strength and durability and which could provide larger glass area and allow in more light. Duration were quick to say it could easily be done, and were content to provide door size less than the conventional size to fit the opening created by the demolished bay window, and they delivered on time before Christmas, and their prices much better than any of the other companies (presumably because they mostly supply direct to the trade). The frame was accurate and the doors slide solid, smooth and free, and lock firm, solid and secure. I would have no hesitation in recommending this firm.
