“Cast-metal systems are jointed with gaskets [or seals], whereas seamless systems are usually riveted together with a gasket material in the joint to provide a good seal.” Like cast metal, plastic gutters also have seals.
While gutters fixed to fascia and the like are sealed, downpipes are not. “Downpipes are loose-fitted, with a spigot above [which joins it to the gutter] and sockets joining the sections below,” says Currie. “This allows the downpipes to be dismantled for removing blockages, such as leaves.”
