This week, Paul and Sara are joined by Darin and Shanese Wells of Professional Foundation Repair, a husband-and-wife team who specialize in foundation and drainage repair. We discuss the most common problems in both slab and raised foundations, some things homeowners can do preventatively, as well as what is required to diagnose and address foundation problems. We also cover what realtors should be looking for when it comes to potential foundation concerns in their listings, when and why you should bring in a foundation/drainage inspector, and why exactly California's soils and earthquakes are to blame for many foundation problems.
