The two-man staff did our 5 windows in one morning with no mess left and a short though comprehensive and clear out-briefing. The manner of the senior partner was professional yet friendly.

Window Installation
From initial contact with company to installation everything went very well. Reason for 4 stars at this time is because of one service issue that needs to be addressed and resolved to my satisfaction.

Overall Very Good Experience
Sales rep was knowledgeable, professional, and not at all pushy. Installers went right to it and were careful to put protective material on our floors. We are very happy with the final product.

Howell, made this window replacement painless. Explained everything in detail to me and gave “me” the choice of purchasing the windows which I appreciate. The windows look great, no mess left behind, and the installers were quick.

My salesman was great and very helpful
My salesman was great and very helpful. The person you measured the windows did a super job, they all fit correctly. The nine man who installed the windows knew what their job was and it was done with care and efficiency. They answered every question I had. What a pile of trash there was and when they left it all went with them. I feel blessed that you have such a great company. Thank you

very good installers
The workers were beyond reproach. They worked carefully and cleaned up after themselves the whole time and answered all questions I had. I really appreciated all the foam insulation and the caulking. Nothing will leak through my windows or around them. If I have any complaint it would be that they called at the end of my 11-2 waiting time to tell me they would be an hour late. I suggest that the installers call clients as soon as they know they will be late. We have much to do in our lives and to wait for hours when they knew they would be late is not a good practice. Everyone would appreciate being able to use their time wisely with notice instead of being irked. We did talk about it and they apologized and said they would not do that again.

All of the installation aspects from the salesman, measurement team, and installers when as planned. Everyone showed up on time and completed things in a timely fashion. The only negative issue was dealing with the payment process where using a credit card charges a 1.5% convenience fee and the web site doesn't give you an option to pay by check or debit card. A check had to be mailed in since the installers didn't take my check and didn't know how to properly use the QRC method.

Windows look great
Windows look great. Installers knew what they were doing. Only problem was the work order, which left something off and the "flashing" issue.
