Thanks to improper installation such as this video and 70% or more of housewrap jobs. Housewrap will actually damage a home more effectively than protect it. Those staple holes/cuts/tears any hole not taped let moisture in where it will be very slowly released as vapour. Many times causing mold or rot. The new homes we test become too tight with housewrap, it usually makes about a 2-4% difference in tightness. Housewraps do very little for making homes tighter. It is for water/weather.
