The salesperson was knowledgeable of his product, was not forceful in getting a sales and was receptive to our budget. The window crew was a well oiled machine. They were professional doubled check our order and verified where all the windows went. From that point we never heard from them again. Installed 13 windows in one day, cleaned the the windows and their work area.

Great service but at a premium cost
I researched multiple companies for a few weeks before I started requesting quotes. While not the cheapest, the sales agent (Daniel) presented a good case for their business. The warranty and the quality of the windows was the most attractive features. I was annoyed at the sales tactic deployed on their web site stating a 50% off deal of the windows cost, while the windows costs were nearly doubled to appear as a good deal. Daniel explained the 50% off was only for the windows themselves, not the installation. I presented evidence of their misleading ploy and provided the costs averages of the same quality window in this region, and they were willing to reduce the price a little. I explained if you stand by the quality of your product, no deception is needed. The crew came out and replaced 18 windows in 4.5 hours. They were professional, fast, and courteous. I just had them installed, so I don't know the impact on my cooling bill just yet, but the windows look great and my home looks better with them. I paid more than I wanted to (more than the regional avg.), but I cannot deny the quality work.

The salesman and the installers did a good job, but trying to communicate with folks in the office (order status and installation questions) was horrible.
