I'm taking a shot in the dark at this, because I've been there. On a couple of occasions, we had some high pressure sales pitches to try to get us to install new windows in our home. They had all of the financing available for us - and more importantly, they were more than double the price of what it would cost to go through a regular contractor. If you have CU loan availability, make sure you shop around on price. Replacement windows are generally trivial to install (very low labor costs) and glass is relatively cheap. For most older homes with "normal" sized windows, it runs around $200 per window to replace them. Oddly, if I recall correctly, for our previous house, the price was the same as slag's: 18k. Going through a contractor who was purchasing them through a respected lumberyard, at that time, would have been well under half of the cost. The companies I'm aware of that make their own windows, install them, and do their own financing are, imho, ripoffs.
