My double glazing is getting the misty condensation problem I have been told they can be repaired or reglazed and not sure what this entails or if it would e better to replace the whole windows. The frames seem absolutely fine and not all the units have gone misty. Any comments from anyone who knows would be great. The salesmen obviously want to sell me new windows and the prices seem exorbitant. I amout of my depth and need to know who to trust and what the facts are. Any recommendations would be good I am in Bethnal green. I did find a window on ebay that would fit but having difficulty finding a builder willing to put it in. Help please. Sarah
