We have a residential customer who is certified OCD. We clean the outsides of all his windows once a month and every two weeks it’s just the outside windows in his pool enclosure. We’ve been doing him for almost two years and it’s crazy easy money, but wecan only be there either Wednesday or Thursday afternoon and he won’t let us clean the insides because he’s afraid we’ll track in dirt…no joke.
He also gets his pool deck surface cleaned once a month, but with another company. I ran into that guy one time while we we’re there and he said he’s been cleaning that pool deck once a month for 5 years!
