Danielle was very accommodating in setting up my maintenance appointment. Isi and Kawika called me 5 minutes prior to the appointment to let me know that they were in the neighborhood. I was impressed by their professional and friendly attitude in taking care of this warranty service and answering all my questions. IWD are the “Clear Difference” in the window business and I continue to refer them to friends, family and acquaintances. Much Aloha to ALL the IWD team.
