I have not gotten inside yet to ensure that the general contractor already had the windows cleaned by the install crew and all the silicone was removed. A good majority of the windows are joined together without a top or bottom frame rail, just a huge line of essentially silicone, though it is a much higher density.
On a 2 story building I average about 42 windows an hour, so let’s assume 1.5 minutes per window. I would be looking at somewhere close to 11 hours. The only caveat is that every 6 months they want to pressure wash the building so I will have a lift and I can do the WFP from there and it will go faster. But the price for the average monthly maintenance cleaning is going to be all from the ground so I have to assume the longest duration. If I went to 2 minutes per pane, as a more conservative time to account for setup and additional resting for my shoulders during the 3rd level cleaning, the overall time would extend to nearly 14 hours. The actual time cleaning may be closer to a minute on the glass, but after about 20 straight minutes on the highest level, I might need to take 15 minutes to relax and hydrate, it is Florida after all.
