Paid for gutter cleaning for gutters that were 2 years old, . Saw evidence of a repair we asked for but not the cleaning. 2 weeks later same problem had to pay for a revisit. Second visit we were home. No one knocked or announced themselves said the work was done. After this last heavy rain I still have a blocked gutter. I have no idea how they flushed the gutter without any one hearing them on the visit. I paid in good faith but I am not satisfied !
