You will find there will be tradesmen within the 'Domestic Cleaning' section that have specialist equipment for cleaning gutters along with pressure washing equipment. Alternatively 'Brick and Stone Cleaning' is a good option for the driveway.
I hope this is of help to you.
Hi holli. You could put the heading under Brick and stone Cleaning for the powerwash of the driveway and mention the cleaning of the gutter within the desciption. Alternatively you could put it under general diy or landscaping as the driveway would come under the landscape heading. Up to yourself really but I reckon you would receive feedback if you put that under the heading.
