Window Quote Reality Check

I was recently quoted over $16,000 for 2 basic sliding glass doors and 9 windows (2 are larger and the rest are all in the standard / normal size). Cedar trim, clear glass, pretty standard request, and we are within city limits. I’m being told by friends in a nearby state that this would only be about $5k for a similar quote.

Am I getting hosed by a company that wanted to see how much they could get from me, or is Bellingham, like always, this expensive for home projects? If so, at that point, I’d pay a premium to bring someone in from another region and take my chances, and still save $8-10k. Or learn how to install my own windows?
