Keeping Leland's Newer Homes Dry: A Moisture Guide

Most Leland homes are new: 12,359 of the town's 14,045 housing units were built in 2000 or later, and the median home dates to 2010 (U.S. Census). Newer homes rarely fail from age. Tight construction, HVAC sizing and 60.15 inches of yearly precipitation (NOAA) make indoor humidity the thing to manage.

A town built mostly since 2000

Leland sits five miles west of Wilmington, across the Cape Fear River, and it's Brunswick County's most populous town. It was only incorporated in 1989. Census estimates put it at 35,731 residents in July 2025, up from a 2020 base of 23,365, and 80.6% of occupied homes are owner-occupied (U.S. Census). With the median home built in 2010, most owners here are dealing with young houses, not old ones.

The first year in a new house

New lumber, concrete and drywall compound give off moisture as they cure, and a new house is built tight enough to keep it in. Run the AC on auto, use bath fans during and after every shower, and keep a hygrometer in a bedroom closet. If it reads above 60% for days at a time, have the system checked while any builder warranty still applies.

A seasonal checklist

• Spring: change the HVAC filter, flush the condensate line, and confirm bath and dryer vents end outdoors.
• Summer: watch indoor humidity; aim for 30–50%. June through August bring 20.69 inches of precipitation on average (NOAA).
• Late summer: August and September are the wettest months, averaging 8.16 and 8.69 inches. Clear gutters and check that downspouts drain away from the slab.
• After any big storm: look at baseboards, door thresholds and closet floors on exterior walls, and dry anything wet within 48 hours.
• Fall: check the attic for roof-deck staining and damp insulation after storm season.

New doesn't mean high and dry

A new house can still sit on low ground. Town Creek flooded 30 homes in Stoney Creek during Hurricane Florence in 2018 (NWS Wilmington), and Leland's planning documents list Sturgeon Creek among its floodplain concerns. Before you finish a garage, add a room or plan landscaping that changes drainage, look up your lot on the Town's Flood Zone Map. Work in a Special Flood Hazard Area needs a floodplain development permit from the town.

When to get help

A musty closet that won't clear, spots on vent covers, or humidity you can't bring down are the usual signs. Read about HVAC and humidity mold or mold inspection and testing, and see the Leland mold removal cost guide for what fixes typically run.
