Cutomer’s UPVC door had not worked since they moved in several months ago. It had clearly been a problem for years as previous owners had bodged it with old fashioned garden gate bolts.
When you see how broken the gearbox is it’s no wonder the customer was unable to get the door open. For us to open the door required removing the glass, and several other steps. New gearbox now fitted and customer has a fully working door.
Recently a landlord had been told by their managing agent that a jammed door would need a complete replacement door fitting. We were able to open and repair the door for probably 1/10th or less of the price of fitting a complete new one.
If your UPCV door is becoming difficult to lock it will probably only get worse. It may only need correctly aligning. This in turn may prevent the mechanism from breaking – saving you money.
