I need to replace sealed double glazed units that are 25 years old, and the seals have perished, so windows are cloudy and full of condensation. Happy to replace the units myself, but need to find inexpensive supplier of new units, or a firm that can recondition my current ones... any ideas?

The old ones can't be reconditioned, but look for Glaziers in the Yellow Pages and you'll have loads of choice! Offer to pay cash and you'll get a good price....
