I recently had a window guy come out to measure and quote me for two windows, each measuring 60.5"x42.25". While he was a really nice person, his quote of $6400 seems ridiculously high to me. I have a friend who can help with the installation, and I've done a few installations before, but only in sheds and garages, not in a home. Considering this is in my house, I want to make sure everything goes smoothly. If I decide to buy a cheaper window from Home Depot that measures 60"x40", will I face any issues? Can I simply shim and spray foam the differences?

If your windows have casing strips around them, this could be a straightforward DIY project. But I’d recommend avoiding cheap options. Check out your local lumber yard; you might find good deals there that are much cheaper—like half the price if not even better! There are plenty of YouTube tutorials to help guide you through the installation process.
Yes, shim those inches! Just leave about 1/4” on each side for adjustments. Make sure you’re buying replacement windows, not new construction types. And don't forget about proper flashing and waterproofing!
First off, getting more quotes is definitely a good move. That price sounds really high. You might want to also check what type of windows you're purchasing—are they replacements or new constructions? The materials can play a huge role too. Consider brands like Marvin Fiberglass versus vinyl. How high your windows are can change things as well!
You’re right; there’s a crazy range in window pricing. Even comparing similar materials can yield wildly different quotes. Your best bet is to gather multiple quotes and find a reliable installer. If you can swing the installation yourself, that’ll save you a good chunk!

Absolutely! Those windows are quite large, and it’s good to know the difference in products could really impact costs.
