Georgia red clay is part of the job in Lawrenceville. It holds water, it moves, and crawl spaces sitting on it stay damp well after the rain stops. Insulation installed over that without a vapor barrier is on borrowed time no matter how good the material is.
Lawrenceville's housing stock spans a much wider era range than most of Gwinnett. From pre-1960 homes near the historic square out to 2010s subdivisions on the county's outer edge. That means the right insulation strategy varies dramatically by address, and there's no one-size-fits-all package that works across the market.
Here's what our crews typically find when they open up attics and crawl spaces in specific Lawrenceville neighborhoods:
Older homes with little to no wall insulation and thin attic batts, where wall injection cellulose and attic top-offs are the standard package.
Executive community with large two-story homes and under-insulated bonus rooms over garages.
Newer subdivision where air leakage at tray ceilings and attic knee walls typically outranks depth as the primary issue.
Maximum air sealing and R-value per inch
Settled blown-in in Lawrenceville's newer subdivisions
Wall cavities in older homes near the historic square
