Why Dunn homes leak

Dunn's housing is among the older stock in Harnett County. The median home was built in 1973, about two-thirds predate 1980, and only about 9% have gone up since 2000. A lot of these houses still have galvanized steel or early copper supply lines, which corrode from the inside and tend to fail at threaded joints and elbows. Many also sit over crawl spaces, where a slow drip can soak insulation and joists for a long time before anyone sees it.

The city treats its own Cape Fear River water and maintains about 115 miles of water lines. City crews make water taps for new homes and repair water services and mains, so a leak at the meter or in the street is something to report to Dunn Public Utilities first. The city's pages don't say exactly where its part of a service line ends, so ask before assuming a yard leak is private. Dunn's 2025 water quality report also notes that a service line inventory is available from the city.

Dunn water carries chloramines (a 2025 average of 2.44 ppm), and chloramine is known to wear down rubber seals, so worn toilet flappers and faucet washers are among the first things a plumber will rule out.

Cost depends on

• How deep and where the leak is: interior wall, crawl space, or buried line
• Pipe material, since old galvanized often needs a section replaced rather than a patch
• How much testing it takes to confirm the location
• Whether the repair is done on the same visit
