I hope @Innocentbystander comments because this stuff is his bread and butter and I want to be him when I grow up, but just slightly less grumpy. Actually, if @Racer and IBS could have some weird pressure washing baby, I’d like to be it. Let me know if you guys plan anything.
A few questions though:
Do you have a hot water machine?
Do they want vinyl (hardiboard? I can’t tell) AND concrete done?
I’ve done a couple apartment complexes and HATED them. Lol. Breezeways are the tedious part.
Currently, this is how we’re doing apartments:
5 buildings once per month, perpetually. Meaning no end to the contract.
If they haven’t been done in years I’d do the first round at double what you were guessing to get them back to a baseline. Meaning as clean as you can reasonably get them.
Then I’d do 10-12 breezeways once every month maintenance washes that way everything was getting cleaned on a quarterly basis.
But then again, I have jobsite ADD and absolutely hate being on the same job site for longer than 2 days.
