Hi All, Able to advise me where can I get good reputable company/ contractor to install a partition with door **** room which link two bedrooms(photos below)? The door will need to save space (foldable?). Reason is because me and wife sleep in one room, kids sleep another room, both no close room door yet wife want to on aircon. Electricity bill super high, Was thinking of getting PD door until I read really bad comments on them with poor workmanship and the door cannot last. Please advise if possible, thanks.
