I was very happy with the quality and efficiency of service today. Mike quickly identified an issue with my front large window and added shims to completely seal the window. He identified an argon leak in one window and will order a replacement. He evaluated each window to ensure they were working properly and showed me some tips for opening & removing. He also redid a screen that needed it. I was very happy with his attention to detail and he was very respectful. Mike was on time which is always nice but you don't see very often from some service companies. Thank you for taking care of me today.
