  • Patent number: 9003870
    Abstract: 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.

  • Patent number: 8707762
    Abstract: 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.

  • Patent number: 7284412
    Abstract: A moisture detection apparatus is installed within a building below a critical area of the building's envelope and has a casing, which may be telescoping, and which as a window on one or both ends. An absorbent material is disposed within an interior chamber of the casing as is a moisture soluble dye that changes color upon contact with moisture and thereby changes the color of the absorbent material which color change is visible through the windows, the moisture entering the interior chamber through at least one upwardly oriented aperture on the casing. The apparatus is installed so that the window protrudes either through an interior wall section of the building's exterior wall, an exterior wall section of the wall, or both. If water penetrates the building, the water enters the casing, and causes the dye to change the color of the absorbent material to alert an occupant that a cladding failure has occurred.
