With 52% of homes built before 1960 and about 70 hard-freeze nights a year, frozen and split pipes are a leading winter risk in the county.
Heavy rain days of an inch or more come about 1.6 times a year here, most often in May. A sump pump that hasn't run since last season is a common weak point.
Backups often follow heavy rain, which Banner County gets about 1.6 days a year, when storm water overloads sewer mains and pushes up through the lowest drain in the house.
In Banner County, 2.83 inches fell on the wettest day of the 2015–2024 record. Storms like that, and ice dams in snowy winters, cause most roof leaks.
69% of occupied homes in Banner County heat mainly with wood or propane, above the Nebraska county median of 19.4%.
About 1 night a year here stay at 65°F or warmer, so basements and crawl spaces can grow mold even without a leak.
Local risk profile
About 742 people live in Banner County, 746 square miles in western Nebraska, in roughly 383 homes. Harrisburg is the county seat. It has some of the oldest housing in the state: the median home went up in 1959.
43/100 Water Damage Risk Index: Moderate Banner County ranks 71 of 93 Nebraska counties. See the statewide ranking and method.The three factors where Banner County ranks highest compared with other Nebraska counties.
Banner County gets more hard-freeze nights than most of Nebraska. From 2015–2024 it averaged 70 nights a year at 20°F or colder, the range where pipes in exterior walls, crawl spaces and unheated garages freeze, and 174 nights at or below 32°F. That ranks 23rd of 93 counties.
The longest cold spell was straight 13 days without the temperature rising above freezing, ending in February 2021. The coldest night reached about -21°F on January 14, 2024. Burst pipes usually show up when a spell like that breaks and the ice thaws.
The freeze season here runs October to April, 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 5 and end around May 11.
Banner gets fewer downpours than most Nebraska counties, but they still fill basements. About 1.6 days a year bring an inch or more (85th of 93), most often in May, out of 17.6 inches of total precipitation. On May 12, 2023, 2.83 inches fell in a single day. The worst three-day stretch dropped 3.97 inches, ending May 12, 2023, the kind of soaking that overwhelms sump pumps and storm sewers.
About 149 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
69% of homes in Banner County predate 1980, close to the Nebraska county median of 73.1%, which ranks 58th of Nebraska's 93 counties.
The mix runs from 52% built before 1960 to 10% 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 Nebraska county median of 5%. 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 Nebraska county median of 14.2%. Empty houses are where a small leak turns into a large claim, because nobody is there to hear it.
Renters occupy 32% 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
Summer nights that don't drop below 65°F, a good marker of humid air, come about once a year here, below the Nebraska county median of 27. 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 Banner County's occupied homes: 3% utility gas, 28% electric, 62% propane and 7% wood. Wood and propane heat are more common here than the state median. Have chimneys swept and fuel-burning appliances serviced each fall, and keep three feet clear around stoves and space heaters.
