1. Measured the 2 windows incorrectly.
2. Showed up with a broken window (many weeks delayed).
3. Installed a window with silicon dripped through. Replaced.

5. Broken the window frame (cobbled together with silicon)
6. Window still has smudges in between panes (triple).
7. Poor communication overall.
8. Window installed was too large for the space.
9. Window was poorly insulated. Frosted in 1st winter.
10. Came with generic trim.
11. In writing "blinds will fit" after new window. Not even close.
Settled for a discount. Didn't want these people near our property again.
