Why Grovetown's Newer Homes Still Get Damp

Grovetown's median home was built in 2008, and 72.8% of homes date from 2000 or later (U.S. Census). Tight, newer houses resist leaks but depend on air conditioning and exhaust fans to remove moisture, and Augusta-area July dew points average 70.7°F (NOAA).

A town built mostly since 2000

Grovetown grew fast once Camp Gordon, now Fort Gordon, opened just south of town, and it has kept growing. The 2020 Census counted 15,577 residents, and the latest Census estimate is about 17,014 (U.S. Census). Only 10.5% of homes predate 1980. About 65% are single-family detached houses, and 8.5% are mobile or manufactured homes (U.S. Census). That mix means most local mold problems start with modern building parts: sealed attics and ductwork, plastic drain lines, and bathroom fans that were either undersized or never ducted to the outside.

Summer air and the tight house

Average dew points at Augusta's Bush Field climb from 59.4°F in May to 67.4°F in June and about 71°F in July and August, then ease to 65.0°F in September (NOAA 1991–2020 normals). June is also the wettest month, averaging 4.75 inches of rain. From late spring to early fall, outdoor air carries a lot of water. A newer home keeps most of it out, but whatever gets in from cooking, showers, laundry and people has to be removed by the air conditioner and exhaust fans. When the air conditioner runs only in short bursts, or a bath fan pushes air into the attic, that moisture settles on the coolest surfaces it can find.

Storms: the Helene reminder

Hurricane Helene dropped 12.02 inches of rain at the Fort Gordon weather station on September 26–27, 2024 (NWS Columbia), and FEMA's disaster declaration DR-4830 included Individual Assistance for Columbia County. Newer roofs and windows still let in wind-driven rain during a storm like that. Water in an attic or wall cavity can sit out of sight long enough for mold to start, so any storm leak deserves a moisture check, not just a patch.

A seasonal checklist for Grovetown homes

• Spring: flush the AC condensate line and check that the drain pan is dry.
• Early summer: keep indoor humidity between 30% and 50%; an inexpensive hygrometer tells you.
• Any time: hold tissue to each bath fan; if it doesn't pull, the fan or its duct needs work.
• After big storms: look in the attic for wet decking or insulation within a day or two.
• Manufactured homes: check the underbelly and skirting for sagging or dampness.
