Have any of you had your double glazing resealed? One of my windows has started to mist over on the inside of the glass panels. It's bugging me as i like to look out the window(nosy git),but i'm now having my view restricted. If you have,did it work/last and how much does it cost? I know prices will vary depending on how many windows you've had done and the style of them.

It's a short term fix at best. I'd bite the bullet and buy new glass,it will save you money in the long run.

no actual need to buy new glass, as its not the glass that is leaking ...

what does need to happen is for the sealed unit to be dismantled , have the inside surfaces cleaned so they are not " dirty " on the inside, then be rebuilt properly .

sadly the cost of that is more than getting new sealed units made. unless your ex lodger mate works in a Glaziers and operates the machine that does the sealing :whistle:

I'd be wanting to know a little more about the valves they fit, see Q10 in their FAQs.
A ten year guarantee sounds good!
Can you find anyone who has has used this company?

Sounds odd to me and the first ive heard of it . It says they install vents in the unit , well that would stop it condensating and probably is the only thing that does but it will make the unit just two bits of glass rather than a sealed unit .

A 500mm x 500mm unit costs me about £30 if I remember correctly. Ring around prices will vary, fitting yourself is not hard in most cases.

Don't forget that when it comes to replacement* if the glass is within 800 mm of the floor or (X distance, I've temporarily forgotten) of a door, it needs to be "safety glass" (toughened or laminated), and marked to show that it is.

*The only sensible option.

As others have said............a new panel is not that expensive and will give you peace of mind. I have quite a lot of double glazing (as we have an extension) and just replace them when essential.
You can google "window Geeks" or similar names..........they specialise in that type of repair.

Ignore - our side window DG has failed. It mists up when the weather is damp and clears when it warms up during the summer.

Don't ignore! Double glazing is an important part of the insulated envelope of your house. Heat losses through 2 sheets of glass are many times higher than through a sealed unit, and when you consider that even the best triple glazing loses some ten times more heat through it than a well insulated wall in which it sits, you can see that retaining failed units in place is simply a way of increasing your discomfort and your heating bills. And spoiling your view.

Moisture inside your DG units is as inevitable as death and taxes. In explanation, the spacers have to be permeable to air in order to prevent the two sheets of glass from moving apart and together as atmospheric pressure changes. Every time the pressure increases a little air seeps in through those little holes (there are no "valves") carrying with it a little moisture, some of which condenses on the inside of the outer pane. Also between the sheets of glass is a moisture absorber, which scavenges the moisture and keeps the atmosphere dry. After some years though this becomes saturated and then you will begin to see more and more misting appearing, sometimes moving around as the micro-climate changes with sunlight and ambient temperature. Time to get the unit replaced with new, and new units will be made from K glass, which is lightly mirrored to reduce radiant heat transmission.

Well, I guess you are literally correct, but well made units can quite easily last 25 years and more. I put triple glazed units in a house in 1990 which are as good as the day they went in, other than the one involved in an altercation with a large piece of farm equipment.

Oh, and there are much better coatings than "K" glass these days, although K glass is much better than nothing.
