Patent number: 9003870Abstract: To address this and/or other needs, the present inventor devised, among other things, a passive moisture detection probe that can be installed and left in place to continuously indicate whether the moisture-content in the wall-cavity of a building is below or above a desirable level. One exemplary moisture detection assembly includes a moisture-absorbent sensor element and an indicator. The sensor element, which can be placed in contact with the inner surface of a home's exterior sheathing, expands and contracts in response to the moisture content of the sheathing. The indicator, for example a rod, moves in responsive to the expansion and contraction of the sensor element, with its relative position corresponding to the moisture in the exterior sheathing and thus providing an on-going and observable sign of moisture intrusion.Type: GrantFiled: December 9, 2013Date of Patent: April 14, 2015Inventor: Alan B.

Patent number: 8707762Abstract: A low-cost, easily manufactured humidity and mold indicator for buildings that incorporates a one-piece transparent plastic injection-molded body. Appearance of a warning icon or a change in color alerts the owners or occupants of a building to a hidden leak and thereby prevents costly structural damage, cosmetic damage and mold damage to building components. The indicator is easily inserted and secured into a drilled hole in panel such as a wall or soffit. In one embodiment, the indicator snaps into place after being fully inserted into the panel. In another embodiment, a retainer inserted into the hole holds the indicator enabling easier removal of the indicator for replacement or for inspection of the area behind the panel. An optional removable cap can be painted the same color as the wall. An optional mask covers the integral viewing window during painting of the device.Type: GrantFiled: November 4, 2011Date of Patent: April 29, 2014Inventor: John Gardner Pfanstiehl
