A lot of Peachtree Corners houses are still running their original insulation, and original here can mean 1976. Fiberglass that old has usually compressed, absorbed decades of dust, and in more than a few attics been disturbed by rodents at some point.
Peachtree Corners' 1970s–1990s development wave produced a large stock of mid-sized homes on wooded Gwinnett lots with heavy shade, which keeps attic temperatures moderate but means crawl spaces stay damp for long stretches after rain. Original fiberglass batts have almost universally been disturbed by decades of HVAC and electrical changeouts.
Here's what our crews typically find when they open up attics and crawl spaces in specific Peachtree Corners neighborhoods:
Established family neighborhood where original attic batts show consistent low spots and pull-down stair leakage.
Larger family homes where crawl space insulation is often sagging or missing entirely and needs full replacement.
Newer townhomes and infill construction where party wall air sealing and attic knee wall insulation are the top issues.
Maximum air sealing and R-value per inch
Topping off settled 1970s–1990s attic insulation
Cost-effective for walls and new construction
Uninsulated basement rim joists and band boards
Safe removal of old or damaged insulation
Pull-down stairs and ceiling penetrations
The original development wave here produced solid houses with insulation packages that were adequate in 1985 and are well short of adequate now. Most owners are surprised how much of the original material is still up there.
