I want to add some new extras for my customers. I would like to offer Gutter Cleaning but don't know how much to charge. I know that several factors effect the price of the job. Lenght, height of the gutters and how long will it take to clean. This is where I need help. I do not have a starting price (for an easy job). I currently offer fall clean-up and leaf removal. What other extras will bring more work?
