:?: I have lived in my present house for 18 months. Over the last 14/15 months a lot of my double glazed units have misted up. eg in one window i have 8 units, 6 have misted and one of them has some water in the bottom. Most of the windows in the house have one or two units that have misted up. My question is; is this normal or is there something else going on. I would hate to pay to have all of these units replaced only for them to go again because there is an underlying problem
I am aware that the seals have failed> What is worrying me is that they all seem to be going within a matter of months of each other and I am concerned that there may be an underlying problem other than a straight forward failure of the seals. Is this possible?
Sealed units fail due to the fact that they are not pressure equalized, the life span of a sealed unit is 5 - 10 years.
New technology alows the units to be repaired and last 4 times longer than replacing.
