Furthermore, these steel plates will be placed vertical. Now if your home has a crippling wall, we will need to replace the damaged existing wood to prevent this cripple wall from collapsing. In some older homes that have not been updated these crippling walls tend to be the weakest part of the structure. We will then add custom cut ventilation holes covered with galvanized wire mesh screen.
