This video is part 1 of a two-part series where I demonstrate how I replaced a load-bearing post and modified the concrete supporting pier to help prevent future wood rot. The demonstration is an amateur effort, published for entertainment purposes only. It serves as a good example regarding why it is unwise to bury any wood foundation below or even near ground level. Before doing any home renovations, be sure you have read and understood your risk and responsibility. Specifically you need to understand whether your local building code requires a building permit, and you should inquire from local building inspection services whether additional work is required. Any misadventure you encounter if you decide to repair your home is your responsibility.
