This is an installation undertaken in Horsham , West Sussex . We installed a sentinel sectional aluminium guttering in a half round profile. We took down all the existing upvc guttering that just could not cope with the long runs of gutter and the amount of joints it had. These were leaking due to the amount of contraction and expansion caused by weathering. We installed this system to the existing Fascias in RAL 7016 anthracite grey, Along with all new ,larger ,matching, round aluminium rain water pipes to cope with the larger flow capacity of the gutters.
