Our locksmiths are receiving many calls regarding UPVC doors expanding during the hot weather. UPVC doors and windows do expand when they are hot and you can incur difficulties opening and closing during the hot months of the year, even more so if you have a south facing door which is dark in colour.
In most cases there is enough play in the door or window to ride this problem out and you do not notice any difference what so ever when opening and closing your windows and doors. If the door or window has been fitted a bit tight your windows and doors can be problematic, in some cases and adjustments will need to be made to rectify this on going problem.
