Marvin Ultimate with new construction install generally start out easily over $1k ea, and you have 3 windows there so I'd definitely say that is within the range of what's normal. Exact install circumstances and options would dictate how good the deal is.

If that is installed, it is a very good price.

Thanks HomeSealedWI and Eastbay10. I had expected about $3000, cause the large window is fixed, and the two casements are pretty small. But I am glad for your advice. I like this contractor, so I wanted to hire him for this window unit replacement.

That is much less than we would have to charge in this area.

Rock start pricing. Not sure how they are doing that project for that king of number when there is likely over $3,000 in materials alone.
