This idea has occured to me whilst working on exterior jobs. Multiple times i have heard my customers complain about previous gutter cleans not actually being done. I am happy to take before and after photos of your gutters so you can rest assured that they have been completely emptied. You don't need any decorating done by me if you don't want/need to, I'm happy to come round and clean your gutters as a one off job. As all my customers know, i take great pride in my work so this will be no exception.
