Moisture meters can help to detect and quantify the amount of moisture that is actually in a building. We may use a moisture meter to check areas around plumbing pipes, air conditioning units, bathroom toilets and showers, and at wooden components near or in contact with the ground surface. Appliances may cause water leaks or cause condensation problems which may result in elevated levels of moisture. A professional inspector with a moisture meter is equipped to find the source of moisture and water problems in a property. Once discovered, all moisture intrusion problems must be immediately corrected before mould growth develops.
