Local risk profile
About 21,217 people live in Grenada County, 422 square miles in northern Mississippi, in roughly 10,444 homes. The county seat is Grenada, and Elliott and Holcomb round out the largest towns. Half the homes here were built before 1983, half after.
43/100 Water Damage Risk Index: Moderate Grenada County ranks 57 of 82 Mississippi counties. See the statewide ranking and method.The three factors where Grenada County ranks highest compared with other Mississippi counties.
Grenada County gets more hard-freeze nights than most of Mississippi. In the 2015–2024 record the county logged about 4 nights a year at or below 20°F (17th of 82) and 42 below freezing. Twenty degrees is roughly where uninsulated pipes start to freeze.
Cold snaps are the real risk. The worst in the record lasted 6 days below freezing (ending February 2021), and the low bottomed out near 6°F on December 23, 2022.
Expect the hardest freezes in January, inside a season that runs January. That's when an outdoor spigot left connected to a hose, or a pipe in a crawl space, is most likely to split.
Freezing nights typically start around Nov 12 and end around Mar 14.
Grenada gets fewer downpours than most Mississippi counties, but they still fill basements. Of roughly 56.5 inches of yearly precipitation, the damage comes from the 14.6 days a year with an inch or more, ranked 80th of 82. February, March and April see the most. The single wettest day in the record: 4.12 inches, February 22, 2019. The worst three-day stretch dropped 7.79 inches, ending June 10, 2021, the kind of soaking that overwhelms sump pumps and storm sewers.
The temperature crosses 32°F in both directions on roughly 39 days a year. Each cycle melts and refreezes water at roof edges and in foundation cracks, which is how ice dams and basement seepage get started.
Housing
Mississippi's 82 counties range widely in housing age; Grenada ranks 38th, with 46% of its homes built before 1980.
The mix runs from 15% built before 1960 to 21% built since 2000, so older neighborhoods bring aging pipe while newer subdivisions bring failed appliance lines and water heaters.
About 33% of homes went up between 1980 and 1999. Some houses from the late 1970s to the mid-1990s were plumbed with polybutylene, a gray plastic pipe known for failing at fittings. A plumber can tell you in a few minutes whether you have it.
Here 14% of housing is manufactured homes. Check the skirting and the heat tape on the main water line every fall, because that one exposed line is what freezes.
19% of homes were vacant at survey time. A leak in an empty rental or seasonal house can run for days before anyone notices, which is why those losses tend to be larger.
Renters occupy 33% of homes. If you rent, the building is usually the landlord's to repair, but your belongings are only covered by renters insurance.
Beyond water
About 117 nights a year in Grenada County stay at 65°F or warmer, a sign of muggy summer air (56th of 82 counties). February is the wettest month. The EPA recommends keeping indoor humidity below 60%, ideally 30 to 50%. Basements can pass 60% on their own in summer, so a dehumidifier matters even without a leak, and anything wet should be dried within 24 to 48 hours.
Mold remediation: what to expectBy main heating fuel, Grenada County homes break down as 39% utility gas, 45% electric, 15% propane and under 1% wood. Most homes here heat with gas or electricity, so cooking and electrical faults are the likelier fire sources. Even a contained kitchen fire can send soot through the ductwork to every room.
