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 given the chance and not being used.
We would recommend re-treating the house between seasons or at least once a year depending on the weather conditions and the use.
