The install went well. A crew of 3 guys. Took about 5 hours to get 9 windows in . Good pace , house wasn't open to the elements for too long. The fishing (chaulking and flashing0 took longer than expected but that was mainly due to weather. Installed on a Friday, left two windows unfinished until Tuesday (they told me at the end of the day Friday they would come back to finish on Saturday, and they finished both of them on Saturday). Very professional job. They cleaned adequately inside the house , did not leave any finger/hand prints on the window frames. Outside they also cleaned everything neatly.
