Moisture detection is also important in the case of water damage from an unknown source, such as a hidden roof leak, window leak, or hidden leak in the building envelope. Maybe you see or smell mold but you don’t know where it’s coming from. Maybe you are noticing staining on the ceiling or walls. In these situations, you need to find the source of the leak in order to fix the problem. Moisture detection and tracing is how we find hidden leaks.
