Windows
I liked this company. However, I hear a cracking noise from my windows every day. I contacted the company, and one of their representatives came and checked all the windows, but couldn't find any problems. Yet, the noise remains.

The installation was completed very quickly but correctly and professionally. The foreman also took the time to go over the installation to make sure that everything was to my satisfaction and even went over the features of my new windows. Overall, a job very well done.

sales person just did not pay attention.
The sales person showed me a window that I thought I was getting and instead I got a inferior window. That did not have the metal locks to tilt the window out. My new windows have the plastic locks for the tilt exactly what I told him I did not want. I have had windows like this before and they failed with in a couple of years. I was very adamant on I DID NOT WANT These. He informed me that if his boss would let him combine 2 orders he could get me a better price I told him fine. So he got me a better price but did not lesson to me about what I DID NOT WANT. I was in a conference call for about 2 hours of the beginning of the install and did not see the windows until they already had about half of them cut out and was installing the new ones. He switched out the windows and did not explain the differences in the two windows.
The installers did an awesome job. They was very courteous and did a very professional job. Their work was top notch.
