Due to Covid-19, we currently are only quoting New Construction Windows.

Windows by the Numbers

Every Energy Star Certified window is tested independently by the NFRC.  A sticker will appear on your new window with the results and these number can NOT be altered.  It is by far the best way to compare the performance of multiple windows.

The top 3 performance numbers to compare are:

 

Energy Star Minimum

Alliance

Alliance Triple Glass
U-Value .30 or less (less is better) .27 .21
Air Leakage .30 or less (less is better) .06 .06
DP-Design Pressure more than 20 40 40

  • Rob is the best! He is an honest salesman and it made all the difference in our experience. We are thrilled with our new double-paned windows. The noise control is amazing and they look wonderful. We were also amazed by how fast his installer got the job done. Rob’s customer service is definitely the highlight of our experience. We would recommend him to anyone!

  • I took 3 estimates on my window and door job for my older condo. Alliance had the best price and it appeared they were offering a superior product at that better price. Of course I went with Alliance and they installed just a couple days after the intended installation time frame. The job was done very efficiently and without incident.
