Installers were prompt, and checked measurements on the doors before proceeding. They showed me the doors and made sure they were the right ones. They did an excellent job cleaning up the awful single pane aluminum doors, and confirmed again when the new doors were placed, to make sure everything was correct.

They took their time, and were precise in how they mounted, and leveled the doors. Checking and rechecking to make sure everything was working properly. They also foam filled any cracks between the new door and the wall/frame, trimmed the excess foam, and then did very smooth caulking over top to provide clean lines.

The end result is sliding doors which are more akin to vault doors in how they keep out sound and the cold. Very impressed and will use them again.
