I had 12 windows installed and encountered several issues with the installation. That said, upon contacting the company, the President personally followed-up with me to ensure I was satisfied with the installation. After sending an inspector, a crew came to my house in a timely manner to make the necessary repairs. I'm happy to report that all the windows have now been installed correctly and I am very pleased with the final result. I have been advised that my windows were initially installed by a new crew but that any issues with that relatively inexperienced crew have since been addressed.
I suspect my experience is not the norm. In other words, that you are unlikely to have similar initial issues with the installation that I encountered, since to my knowledge this has now been addressed internally. And, I can attest to the fact that even if you do encounter problems, that this is a company with integrity that will do whatever they can to make it right.
