The growth of stochastic interfaces in the vicinity of a boundary shows a non-trivial crossover between the behaviour deep in the bulk and a more complex boundary behaviour, related to the causal interaction of the interface with the boundary. This calls for a generalization of the usually admitted scaling laws. This is exemplified in the semi-infinite Edwards-Wilkinson model in one dimension, both from its exact solution and numerical simulations, as well as from simulations on the semi-infinite one-dimensional Kardar-Parisi-Zhang model. The scaling of interface heights and widths is analyzed and an universal scaling form for the local height profile is proposed.
