I have a large triangle shapped window that the seal has been broken on... is there a way or a company that repairs them... the window was a special order 25 years ago & I fear the cost of replacement would be real expensive

I would call your local window companies and get quotes from each of them. They would be better able to assess the damage.

Repair a thermopane window? Not possible according to my glazier. Once the seal breaks air and moisture get inside and start condensing and leaving spots and residue.

I agree with ballengerb1. I have been selling thesr windows for 11 years. Fixing the existing glass unit is not an possible. There are two options - call a glass company in your area to have them replace the glass unit. This may be the easist since the window frame will not be removed from the wall. Second is to replace the entire window unit. This may be the more costly choice since you will be paying for a new window and labor to install it. Of course you would be getting an entirly new window. Check out the costs on both options. The local glass Co should give free estimates. If there is a Lowe's or Home Depot in the area, they can also give the cost for the window and install labor.

Absolutely possible! I restore foggy windows every day.

The Window Medics (defogit.com) process shows immediate results and has a 20 year warranty on refogging. It's not new but is relatively unknown - even in the window business. The cost usually ends up being 30% to 70% less expensive than replacing. Go to the web site to find the dealer in your area - they'll give you a free estimate.
