Had all 33 windows/sliders replaced in 2011 at cost of $18,300 (40% discounted). Work and customer service both outstanding; project complete in 2 days. Glass offers UV protection. Outside noise reduced by about 75%. Installer showed us how negative airflow through home was reduced by about 80% (comparison of before and after). No issues 9 yrs later. Added new 34th window in guest bath in 2015. Again, very professional installation work. HIGHLY RECOMMEND.

Class-Act Customer Service. We all expect great customer service when purchasing a product. However, during a recent 6-window Thompson Creek purchase, after ordering, our decade-old (another brand) installer "coughed up" their still under-warranty 3 replacement sashes for free. I immediately contacted the Thompson Creek customer service department. I timidly asked if they could remove those 3 windows from my package. THEY DID! My husband and I were shocked at their kindness and professionalism. I am singing the praises of Thompson Creek from my rooftop.

POOR POOR LAZY SERVICE!!!!! We wanted to replace the French doors in 4 condos. We spoke with Thompson Creek literally 6 or 7 times to get all the information needed including a letter from our HOA stating it was okay. The appointment was scheduled for 6:00 PM on a Friday night. After sitting at home until 6:45 I called to see where they were. They said oh didn’t someone call you to say they weren’t able to come because of the building you live in. THEY WERE JUST LAZY AND DIDN’T WANT TO COME TO DUPONT! Never use this company!!!!!!!

The installers did and excellent job and thanks to Jairo and Mervin

I got Windows, gutters and a door from Thompson Creek. The product is high quality and the service was great!
