Anything involving building and water just has to be done right. In this video, master builder Matt Risinger walks us through a house where a lot went wrong, and it all involved water. First, Risinger points out the differences between two areas of the house, one where there was a decent overhang and one where there was virtually no overhang to protect against the elements. To make matters worse, where there is no overhang, the housewrap was incorrectly installed, making it easy for water to get in behind the wrap. The result is that the OSB is black, disintegrating and is flaking off. There is not enough air flow to even begin to help this house dry. The house is a mere six months old. Unfortunately, there are a long list of problems. Flashings were missing from the heads of the windows, wherever penetrations came through, they were performed in a sub-standard way. The way that windows were installed, for most of them, the builder put the flashings on three sides of the windows correctly. There is, however, no sill pan underneath the windows. They ran a paper-based flashing, which is an incorrect choice and then the paper was careless cut as the windows was installed. It gave no protection at all to the sill area. The video shows the testing of housewraps, including the one that had been used, which was not waterproof against the one that is waterproof and is in entirely different category. Using water with dye, we see just how fast the water intrudes, especially with the way the wrap was attached. Catch the testing that Risinger and Jordan Smith perform on the wraps Risinger shows a much better alternative wrap with a peel and stick wrap that is asphaltic material that is super sticky and is waterproof and is put directly onto primed OSB.Another option for northern homes it is important to use a more vapor permeable material that feels like denim. Again, a primer goes down first and then the DELTA VENT SA on top. There's no excuse for mold," rot and failure in six months.
