July brings the most downpours to Dubois County, part of 13.8 heavy-rain days a year. Check the sump first.
Backups often follow heavy rain, which Dubois County gets about 13.8 days a year, when storm water overloads sewer mains and pushes up through the lowest drain in the house.
In Dubois County, 2.99 inches fell on the wettest day of the 2015–2024 record. Storms like that, and ice dams in snowy winters, cause most roof leaks.
19% of occupied homes in Dubois County heat mainly with wood or propane, close to the Indiana county median of 17%.
About 46 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
With 18,836 homes and around 43,614 residents, Dubois County is 427 square miles of southern Indiana. Besides Jasper, the county seat, the biggest communities are Huntingburg, Ferdinand and Holland. Half the homes here were built before 1980, half after.
51/100 Water Damage Risk Index: Elevated Dubois County ranks 42 of 92 Indiana counties. See the statewide ranking and method.The three factors where Dubois County ranks highest compared with other Indiana counties.
Winters here are on the gentler end for Indiana, and pipes still freeze. From 2015–2024 it averaged 26 nights a year at 20°F or colder, the range where pipes in exterior walls, crawl spaces and unheated garages freeze, and 98 nights at or below 32°F. That ranks 71st of 92 counties.
The longest cold spell was straight 13 days without the temperature rising above freezing, ending in January 2018. The coldest night reached about -9°F on February 20, 2015. Burst pipes usually show up when a spell like that breaks and the ice thaws.
Most freezing nights fall from November to March, peaking in January. Disconnect garden hoses and shut off outdoor spigots before the first hard frost, and keep the heat at 55°F or higher if you'll be away.
Freezing nights typically start around Oct 26 and end around Apr 17.
Heavy rain is a bigger factor here than in most of Indiana. About 13.8 days a year bring an inch or more (1st of 92), most often in July, out of 52.9 inches of total precipitation. On June 20, 2015, 2.99 inches fell in a single day. The worst three-day stretch dropped 4.29 inches, ending June 20, 2015, the kind of soaking that overwhelms sump pumps and storm sewers.
The temperature crosses 32°F in both directions on roughly 86 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
Indiana's 92 counties range widely in housing age; Dubois ranks 66th, with 50% of its homes built before 1980.
Housing age is mixed: 28% of homes are pre-1960 and 20% are 2000 or newer. Ask any plumber which era your house is from and you'll know which failures to watch for.
About 30% 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.
Beyond water
Summer nights that don't drop below 65°F, a good marker of humid air, come about 46 times a year here, above the Indiana county median of 38. Mold grows when indoor humidity stays above about 60%, the EPA's ceiling. A basement dehumidifier set to 50% and drying anything wet within 24 to 48 hours prevents most problems.
Mold remediation: what to expectHeating fuel matters for fire risk. In Dubois County it's 46% utility gas, 33% electric, 16% propane and 3% 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.
