Our hedgehog houses see a lot of abuse over the space of a year but with the correct maintenance, they should last well into 2-3 hibernation sessions.
Make sure that the house is cleaned out and allowed to dry when not in use when given the chance and not being used.
We would recommend retreating the house between seasons or at least once a year depending on the weather conditions and the use.
