With 33% of homes built before 1960 and about 35 hard-freeze nights a year, frozen and split pipes are a leading winter risk in the county.
Basements flood here mostly in May. Van Buren County averages 5.4 days a year with an inch of rain or more.
33% of homes here predate 1960, when clay and cast iron sewer laterals were standard. Roots and cracks in those lines are a common cause of backups.
Van Buren County's wettest day in the 2015–2024 record brought 3.17 inches, and about 87 freeze-thaw days a year mean ice dams in some winters.
24% of occupied homes in Van Buren County heat mainly with wood or propane, below the Michigan county median of 29%.
About 24 nights a year here stay at 65°F or warmer, so basements and crawl spaces can grow mold even without a leak.

Van Buren County covers 608 square miles of southwest Michigan, with about 75,795 residents and 37,405 homes. Paw Paw is the county seat; South Haven, Mattawan and Hartford are the next largest communities. Half the homes here were built before 1978, half after.
53/100 Water Damage Risk Index: Elevated Van Buren County ranks 35 of 83 Michigan counties. See the statewide ranking and method.The three factors where Van Buren County ranks highest compared with other Michigan counties.
Winters here are on the gentler end for Michigan, and pipes still freeze. It averaged 120 freezing nights a year over 2015–2024, 35 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 79th.
On January 31, 2019 the low fell to about -14°F, and in the stretch ending March 2015 the county went 18 days in a row below freezing. Leaks from split pipes typically appear the day the thaw arrives.
Expect the hardest freezes in January, inside a season that runs November to March. That's when an outdoor spigot left connected to a hose, or a pipe in a crawl space, is most likely to split.
Freezing nights typically start around Oct 28 and end around Apr 29.
Heavy rain is a bigger factor here than in most of Michigan. About 5.4 days a year bring an inch or more (10th of 83), most often in May, out of 40 inches of total precipitation. On August 16, 2016, 3.17 inches fell in a single day. The worst three-day stretch dropped 5.51 inches, ending June 27, 2021, the kind of soaking that overwhelms sump pumps and storm sewers.
About 87 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
Michigan's 83 counties range widely in housing age; Van Buren ranks 62nd, with 53% of its homes built before 1980.
Older and newer homes sit side by side here: 33% predate 1960 and 19% are from 2000 or later. Corroded pipe is the typical failure in the first group, burst supply hoses in the second.
About 28% 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.
Manufactured and mobile homes make up 11% 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
Summer nights that don't drop below 65°F, a good marker of humid air, come about 24 times a year here, above the Michigan county median of 10. 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 expectBy main heating fuel, Van Buren County homes break down as 58% utility gas, 12% electric, 19% propane and 5% 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.
