The majority of 2 storey properties will require the help of professionals and the tools they have at their disposal. However, if the cause of a blocked gutter is just build-up of debris or plants, a simple power wash or hose should do the trick; granted you can easily reach the blockage. Some issues may require replacement joints, especially for leaks and overflows. The best course of action would be to contact one of our professional team to assess the problem quickly, before the cost becomes too much.
