With 23% of homes built before 1960 and about 65 hard-freeze nights a year, frozen and split pipes are a leading winter risk in the county.
October brings the most downpours to Emmet County, part of 2.9 heavy-rain days a year. Check the sump first.
Backups often follow heavy rain, which Emmet County gets about 2.9 days a year, when storm water overloads sewer mains and pushes up through the lowest drain in the house.
In Emmet County, 2.28 inches fell on the wettest day of the 2015–2024 record. Storms like that, and ice dams in snowy winters, cause most roof leaks.
30% of occupied homes in Emmet County heat mainly with wood or propane, close to the Michigan county median of 29%.
Muggy summer nights, lows of 65°F or more, come about 6 times a year in Emmet County. Mold after a leak spreads fastest from June through August.
Local risk profile
With 21,979 homes and around 34,125 residents, Emmet County is 468 square miles of northern Lower Michigan. Petoskey is the county seat; Harbor Springs, Alanson and Mackinaw City are the next largest communities. Much of its housing is recent, with a median build year of 1985.
35/100 Water Damage Risk Index: Moderate Emmet County ranks 74 of 83 Michigan counties. See the statewide ranking and method.The three factors where Emmet County ranks highest compared with other Michigan counties.
Emmet County gets more hard-freeze nights than most of Michigan. In the 2015–2024 record the county logged about 65 nights a year at or below 20°F (26th of 83) and 153 below freezing. Twenty degrees is roughly where uninsulated pipes start to freeze.
On February 20, 2015 the low fell to about -24°F, and in the stretch ending March 2015 the county went 41 days in a row below freezing. Leaks from split pipes typically appear the day the thaw arrives.
Most freezing nights fall from November to April, 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 16 and end around May 14.
Emmet gets fewer downpours than most Michigan counties, but they still fill basements. The county gets about 34.1 inches of rain and melted snow a year, with 2.9 days of an inch or more (71st of 83). Those downpours cluster in June, August and October, when sump pumps and gutters are tested hardest. The wettest day on record brought 2.28 inches on October 23, 2020. The worst three-day stretch dropped 4.17 inches, ending October 25, 2017, the kind of soaking that overwhelms sump pumps and storm sewers.
The temperature crosses 32°F in both directions on roughly 91 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
42% of homes in Emmet County predate 1980, below the Michigan county median of 58.4%, which ranks 79th of Michigan's 83 counties.
22% of homes were built in 2000 or later, more than in most of Michigan. Newer plumbing rarely corrodes, so damage here tends to come from appliance supply lines, water heaters, sump pumps and storms.
35% date from 1980 to 1999, the window when polybutylene, a gray flexible plastic supply pipe, was used in some homes. It's prone to leaks at the fittings, so it's worth checking for in a house from those years.
The Census counted 31% of homes as vacant, above the Michigan county median of 19.5%. Empty houses are where a small leak turns into a large claim, because nobody is there to hear it.
Beyond water
Summer nights that don't drop below 65°F, a good marker of humid air, come about 6 times a year here, below the Michigan county median of 10. 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 expectHeating fuel matters for fire risk. In Emmet County it's 57% utility gas, 10% electric, 22% propane and 8% wood. Heating equipment, cooking and electrical failures cause most home fires nationally. Even a small kitchen fire can leave soot through the whole house, because smoke follows air currents into closets, ducts and attic space.
