OK I know this has nothing to do with Lawn service. But, I got to ask. A new customer wanted a trailer park home power washed. She also said, the last guy who PW charged $100. After accepting the job it took me 2 hours to completely clean it up good. She was impressed at the the detail of clean-up. And commented the last PW only sprayed for about 45 minutes and left. My question is should I honor the $100 or should I ask for more. My estimate is approx. $183. Based on either 0.10 per sq ft x 1830 sq ft. OR I could charge $45 per man hour with 2 person crew. I also used 1 gal of cleaner. Any opinions on how to charge for this type of work?.
