Customer satisfaction

Asher Lasting Exteriors has the process down. The cost is high, however worth it. The initial consultation and booking was thorough and well explained. The process is accurate. After the initial consultation, a team returned to confirm measurements for all windows. Asher kept me updated throughout the process, from setting up the initial appointment, to arrival times, window delivery and installation times. The crew (Keylan and Chris) who arrived and installed the windows were amazing! They were courteous, professional, cleaned and removed all debris during the process. Keylan, Chris, Kolton, Arthur and Gavin were knowledgeable, and this was definitely a professional level install. The company who applied my new siding to my house after the window install commented on what a great installation job this was.

Holt, David C., and Brandon R. – did an awesome job installing my new French patio door. They did beautiful work and I am super happy that I finally was able to replace the old patio door. If I need new windows in the future – I will be using Ashers/Andersen again.
