Starke County averages 38 nights a year at 20°F or colder, mostly November to March, and 35% of its homes predate 1960.
June brings the most downpours to Starke County, part of 6.6 heavy-rain days a year. Check the sump first.
Backups often follow heavy rain, which Starke County gets about 6.6 days a year, when storm water overloads sewer mains and pushes up through the lowest drain in the house.
In Starke County, 5.61 inches fell on the wettest day of the 2015–2024 record. Storms like that, and ice dams in snowy winters, cause most roof leaks.
23% of occupied homes in Starke County heat mainly with wood or propane, above the Indiana county median of 17%.
About 30 nights a year here stay at 65°F or warmer, so basements and crawl spaces can grow mold even without a leak.
Local risk profile
Starke County covers 309 square miles of northern Indiana, with about 23,365 residents and 11,273 homes. Knox is the county seat; North Judson, Koontz Lake and Hamlet are the next largest communities. Half the homes here were built before 1974, half after.
50/100 Water Damage Risk Index: Elevated Starke County ranks 46 of 92 Indiana counties. See the statewide ranking and method.The three factors where Starke County ranks highest compared with other Indiana counties.
Starke County gets more hard-freeze nights than most of Indiana. In the 2015–2024 record the county logged about 38 nights a year at or below 20°F (11th of 92) and 120 below freezing. Twenty degrees is roughly where uninsulated pipes start to freeze.
On January 31, 2019 the low fell to about -20°F, and in the stretch ending March 2015 the county went 19 days in a row below freezing. Leaks from split pipes typically appear the day the thaw arrives.
The freeze season here runs November to March, with January the coldest. If you travel then, leave the thermostat at 55°F or above and open sink cabinets on outside walls.
Freezing nights typically start around Oct 24 and end around Apr 29.
Rainfall is about average for Indiana. The county gets about 41.4 inches of rain and melted snow a year, with 6.6 days of an inch or more (58th of 92). Those downpours cluster in May, June and October, when sump pumps and gutters are tested hardest. The wettest day on record brought 5.61 inches on August 16, 2016. The worst three-day stretch dropped 5.71 inches, ending August 18, 2016, the kind of soaking that overwhelms sump pumps and storm sewers.
About 90 days a year swing from below freezing at night to above freezing by day. Those freeze-thaw cycles feed ice dams on roofs, open cracks in foundations and driveways, and stress pipes that are already marginal.
Housing
Roughly 61% of the county's housing was built before 1980. That puts Starke near the middle of Indiana's 92 counties.
The mix runs from 35% built before 1960 to 18% built since 2000, so older neighborhoods bring aging pipe while newer subdivisions bring failed appliance lines and water heaters.
9% of homes are manufactured or mobile homes, above the Indiana county median of 6.4%. Their water lines run under the floor behind the skirting, so a torn skirt or failed heat tape freezes them faster than lines in a site-built house.
The Census counted 20% of homes as vacant, above the Indiana county median of 9.2%. Empty houses are where a small leak turns into a large claim, because nobody is there to hear it.
Beyond water
Starke County averages 30 warm, muggy nights a year (lows of 65°F or more) and gets the most rain in June. Keep indoor humidity under 60%, as the EPA advises, and dry any leak within 24 to 48 hours; in a humid month a wet basement left alone won't dry by itself.
Mold remediation: what to expectMain heating fuel in Starke County's occupied homes: 67% utility gas, 10% electric, 19% propane and 4% wood. Propane heat is more common here than in most Indiana counties. Heating equipment is one of the leading causes of home fires nationally, and the NFPA recommends having chimneys and vents inspected every year.
