How do you fix a sagging house?

To fix a sagging house, first assess the foundation and identify the cause of the sagging, which could be due to inadequate support, settling, or water damage. You may need to install additional piers or underpinning to provide better support. It’s also essential to address any moisture issues by improving drainage and repairing leaks. If the problem is extensive, consulting a structural engineer or a foundation repair specialist is advisable for a comprehensive solution.
