Windows mist or get full of water or condensation for a variety of reasons, this could be age related, poor installation, or due to weather.
Age of the Sealed Double Glazed Units Can Cause Foggy Glass
As the windows get older, the seals break down. This lets moisture get into what was once a sealed unit and causes the foggy misted glass.
This seems to be a factor in about 10% of the misted double glazed window panes we replace.
Installation of the Double Glazing Can Cause Misted Panes
Bad installation can let the two panes of glass move. This breaks the seal and causes condensation or misted double glazing.
Or it often is a screw that has come up from the frame into the sealant, breaking it, and then you have to deal with the window condensation.
This seems to be a factor in about 60% of the misted double glazed window panes we replace.
We guarantee our installation is free from these problems.
Weather Can Cause Windows to Mist or Fog
Heat from the sun can also break down the sealed glass unit, for instance, a south facing side of the house has much more expansion and contraction of the sealed units than the north facing side.
Then the sealant breaks down and your windows mist or fog.
This seems to be a factor in about 30% of the misted double glazed window panes we replace.
How Can We Help? Misted Glass Replacement!
We replace the blown double glazed units with new ones and take away the old ones.
You can get a quicker idea of the cost if you can take rough measurements of the misted double glazed panes. Then you can give them to us, it is best to send the meaurements to us via email.
Also, can be helpful to send a photo as well, showing the foggy window in relation to the wall.
Don’t worry, we do not use your measurements to order the replacement glass, it is only to give you an idea of cost.
If the quote is acceptable, we will then come out and get accurate measurements and confirm the cost and get your approval before ordering.
Will the misted glass pane problem go away if left, or do I need to do something about it?
Left alone, the misting may well come and go for a time, depending on the humidity, but the double glazed pane is now defective, and the misted pane needs to be replaced with a new double glazed pane. Otherwise, it will just get worse over time.
But the whole window does not need replacing. Only the misted double glazed unit with the condensation needs replacing.
What to Keep In Mind About the Quote
Please keep in mind that there are things that can affect the cost.
For instance, there is a cost difference between clear standard glass, and glass that needs to be safety glass, or has a type of leading, or Georgian bars, or is obscure glass, like found in many bathrooms. If you know your glass is one of these, just mention it. Otherwise we will get a replacement glass quote in standard clear glass, and confirm the type of replacement glass needed after a home visit.
