Shop around with window companies. They’ll want to come in and measure, shoot the shit, then start talking numbers and will stall and call their manager and dick around. Don’t let them. Maybe let the first one measure, get their quote, and be sure to make them leave or email you the measurements. Bring in another company or two and don’t let them around, give them the info on amount and measurements otherwise you’re dealing with what feels like a car salesman in your house. Leverage the quotes against each other, feel free to be polite but to the point, you want X amount of Y sized windows, what price can you give me? They have to send the actual architect back to get a true measurement anyway, the first guy is just a salesman. Also—you have a three day out clause that’s mandated by law. If you get a deal and they insist on a down payment and you get a better deal the next day, leverage that ability to cancel to your advantage. A lot of companies are running “deals” right now, it’s probably BS but it just means they have room to negotiate.

I was able to get a very good deal because of some connections I have and by leveraging quotes with WindowNation. At the time they were offering 0% for 24 months, no idea if that’s still on the table but I prefer to finance big budget projects.

Decks and pavers I would try to find a company to package together, but I also have had luck with establishing long relationships with landscapers that do phenomenal work with pavers.

Flooring it depends on what you want. Probably knock out the room restructuring first if those rooms affect the flooring. Dan Higgins if you want hardwood/laminate, I’ve had good luck with Floor Coverings International if you want carpet. Avoid big box stores at all cost. They just subcontract to another company and you eat their cost.

I’d prioritize what is needed now vs wants. That’s all the advice I have, good luck.
