"Paul and his crew were amazing. I haven't seen three guys work that hard and that efficiently in a really long time. In addition to busting their humps, knocking out all of that work in the short weather-window they had, they were very professional and friendly too. They really took pains to make sure I was satisfied ... nay... elated... with the work. I wish everyone I contract with for work were half-as-good as Paul and his crew.
I was also pleasantly surprised with the quality of the windows they installed. I hadn't really given it much thought, and just assumed they would be cheapo windows, since that is what we have come to expect as the baseline default. They are actually well built, and come with a great warranty too.
If you want the job done right, this is the company to do it. I was extremely impressed.

"Very nice to work with. The crew did a great job. I always imagined that getting a new window well would be incredibly expensive and a huge disruption. Not a all! I hardly knew the crew was there. And no hard sell on new window well. He gave me options and information"
