How do you know a wall is wet when it looks dry?
Many people will ask SERVPRO of Baltimore's Inner Harbor how can they know that moisture is present when it looks dry to the eye?
There has been a great advancement in recent years in technology and techniques that are used by SERVPRO.
SERVPRO will use infrared cameras to identify water location through walls. There is no guess work. Once located, there are moisture detectors, hydrometers and other meters that can measure the extent of the moisture.
All these techniques help to keep the mitigation of walls to a minimum as well as locate any hidden moisture so that it does not get over looked.
