Why you should replace a misted up double-glazed unit

Do you have glazing that looks like this? Condensation and trapped water between the panes of a double glazed or triple glazed unit indicate that the internal seals have failed. This can happen to DGUs and TGUs over time. Result: reduced insulation value, leading to higher heating bills and increased transmission of noise from outside.

Some companies claim to be able to re-seal failed glazing units (and, indeed, DIY kits are available on Ebay and elsewhere). In our experience however, such repairs are rarely successful. The best solution is simply to fit a new double glazed or triple glazed unit. This is still considerably cheaper than replacing an entire window and, to save waste, we will send the old glazing unit for recycling.
