What happens here
The first and often cheapest solution is exterior grading. This involves ensuring that the ground around the house, including any sidewalks or paved areas, is sloped away from the foundation. The video demonstrates common issues like sidewalks being lower than the house's grade, creating a 'moat' for water. It also stresses checking gutters for clogs and ensuring downspouts extend far enough away from the foundation (at least 8 feet, with a 1-inch drop per 8 feet of run). The danger of water collecting against the sill plate is highlighted, emphasizing the need for proper grade to prevent issues like dry rot.
Goal: Correct ground slope and downspout drainage around the house.
