The key to this job is to set low expectation’s, looks maybe 26feet high max base on the size of the door . Get up there scrub with applicator , then here is the key you rinse with your WFP hose . No need to get your pole up there , just lots of rinsing straight from the hose . I don’t think the outside should take 2-3 hours max , not sure about the inside. But like others shave said , their budget is probably $200 lol .
I dont mind the hard work to be honest. For me, its just a contract. I dont mind charging more for hard work. If they dont accept the price. Too bad. I just dont want to look silly with a crazy number.
From those pictures I can’t even decipher what’s in need of cleaning or what it looks like.
Just going by your description I’d toss out some wild number, that seems really high for the PITA (like $2-3k for annoyance and hard work) and then have a clause that states something like “due to the nature of this job windows may not come out perfect and blah blah blah…” whatever wording
I personally prefer straight forward jobs and the really hard work or wild windows aren’t fun like they were my first couple years doing this
i’d almost say a custom tool that combines the flexibility/pivoting and movement of a “doodlebug”, a 24" strip washer or flat micro scrub or whatever applicator to agitate at whatever minimum overlap length you need, and a rinse bar
