After meeting Timothy and Nick, from Quality First Home Improvement, who were very attentive, patient, and knowledgeable salespeople, assisted me in purchasing ten, high quality, energy efficient double pane windows, and one sliding patio screen door, "that has prevented insects from getting inside!" The installers did a very good job, including an immaculate clean up..... "and a special thank you to Troy and Cesar for following through during the project!"
