Very frustrating
Placed a warranty claim on one of our windows that the glass had cracked. Of course I had to pay $150 up front for labor. Then I had to keep calling as I received no response from WN. So then the tech shows up at our house but without the replacement glass. To make matters worse, once the tech got the replacement glass, it cracked as well. So now I will have to wait another 6+ weeks. Horrible customer service!!!

Was a good experience
Klaudia, sales rep, was very knowledgeable and helped to meet our needs. She was understanding and listened to our concerns. When we called her about a concern she called us back in a timely manner.
The installment happened well before the date we expected. The installers came and completed the job in a timely manner even finishing up almost an hour earlier than projected.

The installation of my new windows was very successful. The two men who came to install the windows were on-time, professional and respectful of my property. They used dust cloths and plastic to protect my furniture, rugs etc. They cleaned the windows after the job was completed and they vacuumed almost my entire house. I love the new windows and they made the process painless!!
