If you live in Jackson and a stair-step crack showed up after a dry month, the first hour is the same as anywhere else: mark the crack, check the doors, then decide who should look. What to do when the house is cracking or settling is that order.
The local part is the clay. Mississippi Geological Survey Circular 1 says Yazoo clay is the informal name for the Yazoo Formation, that it crops out in a belt across central Mississippi, and that foundation damage in that belt, especially in the Jackson area, is caused primarily by the clay's expansive nature. When is a foundation crack serious? is the short version.
Permits for the repair
A city permit is not a bid. Jackson's building permit office requires a permit to construct, enlarge, or repair a building. MSBOC sets the dollar lines for a residential license. Ask for the license number before anyone digs. How to choose a foundation contractor is the checklist.
What it costs here
We do not print a Jackson crew price, because we do not have a sourced local list to show you. Ask the company for a written scope.

Permits and registration
The City of Jackson Building Permit Office issues construction permits and requires a permit whenever an owner or the owner's authorized agent proposes to construct, enlarge, repair, move, or demolish a building, including structural work. Jackson has adopted the 2018 International Residential Code with amendments. MSBOC says a state license is required for new residential construction over $50,000 and for residential remodeling, additions, or roofing over $10,000. A city permit is not a soil report.
Climate
The climate figures are 1991-2020 U.S. Climate Normals for Jackson, station USW00003940, from NOAA's National Centers for Environmental Information. January mean temperature is 47.0 F and January precipitation is 5.42 inches. July mean temperature is 82.1 F and July precipitation is 5.02 inches. December mean temperature is 49.1 F and December precipitation is 5.13 inches. The mean of the twelve monthly mean temperatures is 65.4 F. The twelve monthly precipitation normals sum to 57.35 inches. Wet winters and hot summers are when Yazoo clay often shrinks and swells.
About Jackson
