Matt installed three banks of 3 blinds each and one bank of 5 blinds. Three of the banks were installed with no gaps between the blinds because the windows were flush with the walls == that is, they were not recessed. This was done with such precision that when the slats are in either the closed position or the open position, they are perfectly aligned, so that they almost appear as one blind. This is very impressive. The majority of these blinds was installed on a sun porch where the windows at two corners come very close to each other. We thought there might be a problem with the blinds on the corners because of their closeness, but Matt was able to install them so that they open and close easily without interference with one another. The work was done in a timely fashion. Matt was a pleasure to work with. Edward P.
