Colquitt County, GA Insulation Payback
Colquitt County attic insulation, by the numbers
Colquitt County, Georgia is zone 2 under DOE's climate map (Hot-Humid), which means long, muggy summers and mild winters, where cooling dominates the energy bill. An uninsulated attic there should be built up to R-49. Going from R-2 to the recommended R-49 costs roughly $2,820 installed for a typical attic (about 1,000 sq ft), and pays for itself in about 3.4 years at an estimated $836/year saved. Topping up the attic pays for itself here.
Where the savings come from
Split it out and it's roughly $472 a year on the heating side, $364 on cooling. By estimated insulation savings, Colquitt County lands in the 6th percentile nationally. Zone 2 alone covers 233 counties in this dataset, and Colquitt County comes in 134th by savings. Georgia averages $974/year across the counties tracked here; Colquitt County comes in 14% lower.
Where these numbers come from
Colquitt County's climate figures — 1,779 heating and 2,286 cooling degree days a year — are read from MOULTRIE 2 ESE, GA US, 1.5 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Colquitt County sits at the 3th percentile nationally. One local detail the R-value alone won't tell you: Colquitt County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
The smaller top-up scenario
Already have a few inches up there? Topping R-11 up to R-38 runs about $1,620 for about $113/year saved — roughly 14.4 years to break even. Call this borderline rather than a clear win.
Getting it done in Colquitt County
Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $2,820 as a starting estimate for a Colquitt County job, not a quote. Expect at least a $600 minimum charge from most contractors.
