Once an insulated widow looses its seal, can it be repaired?  Have a big window that's lots its seal and I'd think glass that big is gonna ber expensive.

Strange you should mention that. I have 3 that have moister inside, Just haven't got around to researching it yet. A couple of places I checked seemed to indicate that they can be repaired. For how much $$ and how long it will last I haven't found out  I'll be watching this thread.

Phu Cat and ceduby, Here's some reading for ya. I didn't spend a lot of time looking I just googled "thermopane window repair" I have about 6 windows in my house that need it also. I think this place is on the east coast  somewhere.

That repair sounds like you will lose the insulating air space between the panes.
Those windows come apart fairly easy. Take it apart on a nice day and take the glass to a window shop so they can measure it and make you a new one, I've done it several times.

I have a few myself including 2 sliders...$$$$$$$$$$$$$$$$$$$$$...

there is a place here that replaces car windows but they will re seal house windows on the side I think the big thing is what the window is made of my old windows were wood with a vinyl covering of course when I took them out most of the wood was rotten so no chance of fixing them had to replace them ,Check out your local automotive glass shops see if they can do it .

The guy that took our window out so he could make a template for the new window swears they can't be repaired, that the old windows are too hard to clean to make 'em look right again.  I'm not buyin it.  The manufacturer was able to clean that window just fine the first time it was sealed.  There's gotta be a way to clean, reseal, and put some gas between the panes that won't condense.  It just doesn't make sense to not use the old panes of glass (except for the problem of not having a window in the opening.  I could have cut some plywood to fit in there temporarily) cuz ya know they'll fit.  Will the new one made from the template fit as well?  Somethin makes me think there's something underhanded going on here.  Think I'll insist on keeping the old window tho.

used to be so easy back when.  All my mum had to do was remove the putty, take the cracked windows pane out, replace with new and putty back again.....

It would probably cost you more to do it your way than just buying new insulated glass units. If yours were low-e, then the glass is probably pretty badly clouded. Probably not repairable. Any reputable glass shop should be able to have new units made up for you.  You can get simple insulated glass or a number of different types depending on how much you want to spend and how much insulation you want.  Down here in the south, we look more at the heat gain issue in the summer, rather than the heat loss in the winter. 
I agree someone could probably reseal your glass, but its really not the way to go IMO.  I've got two big fixed glass units I'm gonna have to break down and replace before long.   Last time I got a quote a couple of years ago, it was almost $1000 for both of them.  Now I've got some double hung sashes leaking as well.  Not too bad really.  they all had a 5 year warranty, and they lasted 15 to 16 years.

I take it you are talking about double glazing ?. The insulated unit probably does not have gas in it, and it will only be the seal that has broken. Any dg manufacturing company can re-use the glass and make a new unit, but they would probably split it at your own risk of breakage. If you have a local company that manufactures, get a quote for a brand new one with a guarantee. If costs are anything like here in the UK you should only be paying from around $30 to $35 a sqr yd, including low e glass.
