Recently got an aluminium g/house off Freecycle but door is buckled and wont slide. Is there anywhere that you can get spare parts? the front part of the frame that the door runs along is all but unusable but I dont know what make of greenhouse it is. Are greenhouse parts 'standard' or do they only fit their own models. Your help would be much appreciated as I've scoured the net to no avail.
