"My overall experience was wonderful! Beginning with Chris, my sales rep, to the young men who came to conduct measurements and go over logistics with me. They took their time and answered all my questions. The installation crew were courteous, professional and friendly. At end of installations, the project manager made sure that I checked all aspects of the windows, from hinges, to opening and closing and testing for any draft. He and his crew also cleaned up after themselves. And let's not forget Diana (my new bestie), who kept me abreast of project with updates. Truly a great experience!!!! I highly recommend and will conduct any future door, window or sliding installation with Ecoview."
