"It went really well!
Prompt response to my original request. Prompt arrival for ALL subsequent visits - by the sales rep, 2 different measurement guys, and the installers.
We had a very tight schedule and they met it.
The installations were done beautifully.  I was personally home for the door installation (the windows were done on a separate day) and I can tell you that the two guys paid alot of attention to all the details, tested the door, cleaned the door, swept up after themselves, etc.  They were very courteous throughout.
I am SO happy with my new windows.  3 of them were straight-up replacements. And never have I had windows that slid up and down so well.  And the 4th was a replacement of my kitchen over-the-sink window with a window that cranks open.  It is lovely.  It is a huge window, but even my 9 year old can crank it open and closed.
I am already planning on calling them again for several more windows and would recommend them to anyone.

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"Install was easy. Up front cost was pretty low with Angie's List coupon. Monthly price is a little high compared to competing companies. Response time with alarms is excellent. I was advised to use glass break alarms within 10 ft of my first floor windows, which we installed correctly. I asked prior to installation if having one in the kitchen would cause false alarms due to dishes clanging, etc. I was told the glass break alarms are configured to a precise frequency that alarms with breaking glass. So, not a "no", but not really an answer. Well, every time we cook dinner, wash dishes or empty the dish washer, the kitchen glass break alarm gives a warning which would sound the alarm if it was set. This has caused us a number of false alarms while we've been away due to shifting bowls or plates in our drying rack. For the first several we've had to pay our police department $120 to check the house, and I was only notified after the first alarm that there was a cheaper option for a security company to drive by to check for a break in."
