Window Clean

I received a flyer on my door and called him to get an estimate.  John called back within a few hours to set up an appointment for an estimate.  He was out to provide the estimate within 15 minutes of the call.  He quoted 175.00 to powerwash the house, wash the outside windows, and replace the piece of siding.  He called back to set up the appointment two days later, scheduling for that Friday between 8:30 and 9:30.  He arrived shortly after 8:30 in the morning.
As were were working he noticed that a gutter was coming loose and hanging off the roof and that there was build-up in the gutters.  He only asked for another $25 to do the gutter cleaning and nothing extra to re-attach the gutter.  The windows are spotless and the house is clean even around the drive way and front porch.  When he was unable to get the screens out, he came inside and removed the window to clean the outside and replaced the windows.  All items were put back where they were found and he cleaned up after himself.
I ended up paying him 300.00 even though he only asked for 200.00 because of the great job he did.
