Disclosed are means for detecting water or moisture in a building, or a quality of a building material within the building. The means include an electrical first line (401) extending to measurement sites at timber framing within the building; an electrical second line (402) extending to the same measurement sites; moisture sensors (403) connected to the lines at different sites, each sensor having a respective switch means (405); a resistance meter (404) which can be connected to the lines; and means for opening and closing the switch means. When a switch means is closed a circuit is formed so that respective sensor is active to enable readings for that sensor to be taken at the meter (62) Divided Out of 578082
