Local risk profile
About 83,757 people live in Midland County, 518 square miles in central Lower Michigan, in roughly 37,160 homes. Midland is the county seat; Coleman and Sanford are the next largest communities. The county's median home was built in 1975.
42/100 Water Damage Risk Index: Moderate Midland County ranks 63 of 83 Michigan counties. See the statewide ranking and method.The three factors where Midland County ranks highest compared with other Michigan counties.
For frozen pipes, Midland County is a typical Michigan county, which is still plenty. It averaged 130 freezing nights a year over 2015–2024, 46 of them at 20°F or colder, cold enough for pipes in outside walls and crawl spaces to freeze. Among 83 Michigan counties that's 50th.
Cold snaps are the real risk. The worst in the record lasted 18 days below freezing (ending March 2015), and the low bottomed out near -20°F on February 20, 2015.
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.
On average the first fall freeze arrives around Oct 23 and the last spring freeze around Apr 28.
Rainfall is about average for Michigan. The county gets about 32.8 inches of rain and melted snow a year, with 3.7 days of an inch or more (46th of 83). Those downpours cluster in June, August and October, when sump pumps and gutters are tested hardest. The wettest day on record brought 2.97 inches on June 23, 2017. Multi-day storms matter most for basements; the wettest three days on record here totaled 4.33 inches (through May 20, 2020).
The temperature crosses 32°F in both directions on roughly 88 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
Roughly 58% of the county's housing was built before 1980. That puts Midland near the middle of Michigan's 83 counties.
Housing age is mixed: 26% of homes are pre-1960 and 16% are 2000 or newer. Ask any plumber which era your house is from and you'll know which failures to watch for.
26% 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.
Manufactured and mobile homes make up 8% of the housing here. Water lines in the underbelly depend on intact skirting and working heat tape, and they're usually the first to freeze in a cold snap.
Beyond water
Midland County averages 19 warm, muggy nights a year (lows of 65°F or more) and gets the most rain in August. 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 Midland County it's 66% utility gas, 13% electric, 16% propane and 4% 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.
