I think these guys did a great job from quote to install and I'd definitely recommend them. My only hesitation is that they seemed a little too busy which resulted in me having to follow up a few times about quote revisions, drawing revisions, questions, installation confirmation, etc.
I appreciated their professionalism during the quoting process. I had received four quotes before choosing Go Green and I found two of the four other vendors fairly unprofessional in their unfounded bashing of their competition. That kind of behavior doesn't really inspire trust, and I feel you have to have some trust when it comes to something as expensive as windows. I'd like to see more female sales reps in the window industry in general (none of the quoting companies had female reps).
Go Green gave me a competitive price and the quality seems good so far. I ended up doing a full frame replacement (the more expensive but thorough option) but I appreciate that Go Green was able to do either and discussed both options fully with me without pressure.
The installers were great - very polite and tidy young fellas. It seemed that one had worked with GoGreen for 9 years and the other 2 - both a good long time - which probably speaks well of the installation quality and also Go Green as an employer.
