Spray Foam Insulation in North Augusta, SC

Spray Foam Insulation in North Augusta covers homes on the South Carolina bank of the Savannah River, directly across from Augusta. Wikipedia notes the city sits at about 469 feet, mostly in western Aiken County with a small part in Edgefield County. It began when the North Augusta Land Company bought a 5,600-acre tract in 1890 and incorporated in 1906. It has been growing, from 21,348 residents in 2010 to 24,379 in 2020, with a 2025 estimate near 27,000.

Older and newer homes

The original planned town holds older homes, many on crawl spaces, while newer subdivisions have ducts in the attic and bonus rooms. Both share the same hot, humid summers as Augusta.

South Carolina code

South Carolina's Building Codes Council lists the 2009 IECC as the mandatory statewide energy code since January 1, 2013. OpenEI lists Aiken and Edgefield counties in Climate Zone 3A.

Permits

Aiken County's planning department handles building permits countywide but excludes the city limits of Aiken and North Augusta, so city projects go through the city.

Attics and crawl spaces

Sealing the ceiling and blowing loose fill deep, foaming the roof deck where ducts are tight, and encapsulating humid crawl spaces are the main jobs.

Costs

HomeGuide lists crawl space encapsulation at $3 to $10 per square foot and attic jobs at $1,000 to $2,700 nationally. The written estimate is the price.

Riverside and hillside homes

North Augusta climbs from the Savannah River up into the hills. Homes on lower ground near the river can have more humid crawl spaces, while hillside homes catch more sun on west-facing walls and roofs. Both benefit from a sealed attic, and the lower homes in particular from crawl space encapsulation.
