Respectful to my home and decorations. Worked quickly as a team to replace a large window. Answered my questions and were available during the entire process. I love Millard windows and team members with their outstanding warranty.

We bought a new window for our cabin from Diana. She was very helpful with specifying the right size and configuration for us. Also, we couldn't take delivery as soon as it was in, so she kept it in her warehouse for a few weeks until we could. We have more windows to replace, and plan on going back to Windows Only for them.
