iv done this house a few times its only 3 windows +its on a street were I have a few houses to do .nothing out of the ordinary charged £2.50 3mins of a job. Did the job awhile ago then went to collect ,nobody in .did this for a few days no answer. The day came round to clean them again so I did .I cleaned them then on collection day same again no answer.....I have a few customers like this but its because of work (they work silly hours )but I know they always pay up at end of the month ,so no worries. But this house wasn't normally like this,so I posted a card that said here's my number pls get in touch then we can arrange payment. Nothing no answer. The day came to clean that street again and I thought to myself do I do them or not only to see the house is empty. Not bothered about the money just they could of text "saying we re moving "that would of been enough.loll any way i posted another card through the letter box for the next household ,if you need a window cleaner it'll be £2.50 for the front and here's my number.
