Alpharetta housing stock and foundations
Two-story traditional and transitional homes built during the 1985-2006 North Fulton boom, nearly all on poured or block stem-wall crawl spaces with fiberglass batts stapled between the floor joists and a thin 6-mil sheet loosely laid on the soil.
Stem-wall crawl spaces with generous 36 to 48 inch clearance, which makes Alpharetta among the easiest cities in the metro to encapsulate correctly.
Soil: Cecil sandy clay loam over saprolite, with Big Creek floodplain soils along the greenway corridor.

Water and climate
Big Creek and its tributaries. Subdivision-era detention ponds were sized to 1990s standards and several now discharge toward downhill homes during high-intensity storms. North Fulton runs a few degrees cooler than intown, which lengthens the spring and fall condensation season inside vented crawl spaces.
Elevation 1,150 ft · Population approximately 68,000 · 26 miles from Atlanta

What goes wrong under Alpharetta houses
- Fiberglass batts saturated and hanging off the subfloor in 1990s homes
- 6-mil vapor barrier laid loose, torn, and not sealed to the stem wall
- Undersized subdivision detention discharging toward downhill crawl spaces
- HVAC ductwork in the crawl space sweating and dripping onto joists
The Alpharetta pattern
Alpharetta has the most consistent crawl space inventory in the metro, and the most consistent failure. A home built between 1988 and 2004 here almost certainly has fiberglass batts stapled to the underside of the subfloor and a loose 6-mil sheet on the dirt. That assembly works until the batts absorb enough humid summer air to lose their grip, and once they fall, they hold moisture against the joists instead of insulating them. The fix is not more batting.
Crawl space costs in Alpharetta
Alpharetta prices about 3 percent below the Metro Atlanta average. That is driven by documented local conditions rather than by postcode.
