Hurricane Impact Windows - Who to choose?

[Ashraf Spahi]

Hello,

I'm working on a flip in the Miami area and I'm looking to change out all the windows. I've dug around and talked to a few window people to get estimates and it seems like each installer is trying to sell me on a different brand and I'm trying to understand the differences and advantages of each. 

The brands I've been bid on have been:
Eco Windows
CGI Sparta Series
Lawson Industries
ESWindows
Assura

Assura is from home depot, main advantage i've found is that they have a quick lead time of 4 weeks, compared to everyone else saying 6-8 weeks.

CGI I heard its a reputable brand with a good warranty 

Lawson, cheapest quote but Im' hearing has a huge lead time now and they have been messing up peoples orders with sizes or specifications

ES Windows, comes from Colombia and I heard spare parts, replacements and customer service is terrible

Eco, I haven't really heard much about but price seems close to what I'm being quoted for CGI Spartas 

Anybody on here with more experience that can help me narrow it down?
