Split-levels define Dunwoody, and split-levels leak in predictable places. Cantilevered floors hanging over open air, bump-outs, stair landings between conditioned zones. All of it built in the 1970s and 1980s when nobody was thinking hard about air sealing.
Dunwoody's 1960s–1980s ranch and split-level stock sits on wooded lots with heavy shade, so attic temperatures run lower than in newer subdivisions but crawl spaces stay damp much longer after rain. That combination shifts the priority away from radiant barriers and toward air sealing at attic penetrations and crawl space vapor management.
Here's what our crews typically find when they open up attics and crawl spaces in specific Dunwoody neighborhoods:
Wooded split-level and ranch homes where original fiberglass batts have been disturbed by decades of HVAC work, leaving obvious low spots.
Larger family homes where crawl space rim joist sealing and encapsulation produce the biggest single comfort improvement.
New townhomes and mid-rise condos where the primary issue is party-wall air sealing and attic knee wall insulation continuity.
Maximum air sealing and R-value per inch
Restoring depth over disturbed 1960s–1980s batts
Cost-effective for walls and new construction
Uninsulated basement rim joists on split-level homes
Safe removal of old or damaged insulation
Pull-down attic stairs, the most common Dunwoody leak
Homes from Dunwoody's original build-out are structurally sound and worth investing in, but the insulation in them has had decades of trades working around it. What's up there today rarely resembles what was installed.
