North Carolina has just emerged from a hot, dry September, and the consequences extend well beyond brown lawns. Climate researchers at NC State University report a preliminary statewide average of 2.63 inches of rain for the month—about half of normal—ranking it the state's fifth-warmest September since 1895. Raleigh, the closest major reporting city to Sanford, recorded only 2.17 inches, or 42% of normal. That lack of moisture is now affecting the ground beneath homes in Sanford and across Lee County, where clay soils dominate.
The NC State Extension Gardener Handbook notes that clayey soils often have shrink-and-swell characteristics that affect construction uses. When a house sits on clay and that clay dries out, it pulls away from the water service line, the sewer lateral, and the pipes under a slab. The ground supporting those pipes can shift, creating small separations at joints or cracks in older lines. The result is rarely dramatic at first—a joint on an older sewer line separates slightly, a supply line under a slab starts to weep, or tree roots searching for moisture find a tiny crack in a drain line.
Homeowners may notice subtle signs: a water bill that creeps up without a change in use, a drain that gurgles or backs up, a damp or warm patch on a floor, or the sound of running water when every fixture is off. Comfort First Heating and Cooling, a Sanford-based plumbing and HVAC contractor, says the weeks following a long dry stretch are the cheapest time to find hidden leaks. The company's plumbing services at its Sanford location include pipe repair and replacement, drain cleaning, slab leak repair, water heater repair and installation, tankless systems, sump pumps, gas lines, and fixture repair. "Most people think about pipes when it freezes, but a long dry month moves the ground too," said Adam Hagen, General Manager. "Clay soil shrinks, the pipes settle with it, and a joint that held for years starts to leak where nobody can see it. Checking the meter with the water off takes five minutes and tells you whether there is a problem worth looking at before the cold weather arrives."
For residents, the implications are both practical and financial. Undetected leaks can waste thousands of gallons of water, drive up utility bills, and lead to expensive repairs if left unchecked. Early detection is key, and Comfort First offers a simple checklist: turn off every faucet and appliance, then check the water meter—if it still moves, water is going somewhere. Compare this month's water bill with the same month last year. Listen for gurgling drains or a toilet that refills on its own. Walk the floors barefoot and note any warm or damp spots on a slab. Watch the yard for a patch of green grass or soft ground above the sewer line during a dry week. Finally, find the main shutoff valve and make sure it turns freely before winter.
Comfort First Heating and Cooling serves Sanford and the surrounding Triangle area, including Cary, Apex, Garner, Pittsboro, and Carthage. Local plumbing service details are available on the Sanford service page, and the team can be reached at (919) 295-3421. With winter approaching, addressing pipe stress now can prevent more costly emergency repairs later. As the region recovers from an unusually dry September, homeowners should pay attention to the ground beneath their feet—and the pipes within it.
