Moisture has gotten inside your sealed unit and the only remedy is a replacement glass unit, this is far less expensive than replacing the complete window or door.
There are 2 main reasons for this. Either the locking mechanism may need adjusting/replacing or the hinges may need replacing.
Most commonly, just an adjustment is required. But only if the door lock works when the door is in the open position.
This could be due to the handle being faulty, or the locking mechanism inside the window being broken, but both can be repaired, just ask us for a free quote and we will take care of it.
Yes, if you can tell us about your double glazing problems, we can normally diagnose the issue and supply you with a price over the phone. Same goes for other needed repairs.
