I just got quotes from four companies:
Window World - baseline quote with no intention of selecting them. Cheapest option with questionable crews. Some great, some bad. Only one window option.
Superior Windows - Tried to upsell to reinforced vinyl with aluminum core. Pretty terrible high, pressure sales experience (3+ hours) and had to force the guy out of the house. Most expensive of the four quotes I got.
Ultra Windows - recommends aluminum windows, which aren't as efficient as vinyl but stronger. Best install process / crew of the people I talked with. Middle price point. Efficiency is only as good as the install imo. Son is an Aggie.
Houston Window Experts - sell all kinds of brands and can install whatever you want (vinyl, aluminum, fiberglass, wood). Vinyl quote I got was in the middle of bids. Felt okay about their install process and no high pressure sales. Didn't love the product I was quoted, but like I said they have many options
