Yes, it's a big-un. Luckily, the window is in an 'out-cropping' from the house - so hopefully when we replace it with a slightly smaller sized window(s), the whole front of the house won't need to be re-worked, at least. We're actually considering two or three nice casement windows, side-by-side. And definitely going with the Low E stuff - the window faces due west.
We have a contractor we like, though he's definitely not the cheapest, we do trust him and he's done a lot of great work for us. I think we'll get him out for an estimate and go from there. I might even sneak in a new front door, if the price is do-able.
So, does everyone go with vinyl windows now? I saw some (very pricey) wooden ones - but is the wood on the outside too? Isn't that a LOT of maintenance? Our house is tan and brown, and I think the wood might look nice, but the price will be a big factor.
Thanks for everyone's input and for the bump, Brandy...Liz.
