We are equipped and trained to perform real-world water testing on windows, walls, doors, rooftop flashings, and decks. We look for how your building components will respond to the elements while being washed or in a rain storm or on a windy day. In our view, this is the helpful information that maintenance personnel, property owners, and construction quality control supervisors need; they do not need to know whether or not a window, for example, will leak during 15-minutes of water delivered at a specific psi from a specific distance while subjected to calibrated negative air pressure.
