I'VE HAD THREE TRI FOLD DOORS MADE AND FITTED (FOR SECURITY PURPOSES) TO THE UPSTAIRS ROOMS OF MY HOUSE. THE FLOORS HAVE BEEN SCREEDED IN PREPARATION FOR TILING WHICH HAS CHANGED THE BASE DIMENSION OF THE DOORS. CAN YOU SUGGEST A WAY TO OVERCOME THIS DISCREPENCY WITHOUT HAVING TO BUY NEW DOORS?[/img]
