House leveling is the process of lifting a home when it is sinking. When a house sinks it creates structural problems. Sinking will pull at the walls and the roof, can put the plumbing into the ground, rip the ceiling apart, and more. These problems cannot simply just be fixed. House leveling, along with fixing the source of the problem, will help correct those issues.
