Pulaski County, VA Insulation Payback

Is attic insulation worth it in Pulaski County, VA?

Pulaski County, Virginia is zone 4 under DOE's climate map (Mixed-Humid), which means a genuine mix of cold winters and humid summers, with neither one dominating the bill. An uninsulated attic there should be built up to R-60. Topping up a typical 1,000-square-foot attic from bare joists (R-2) to R-60 runs an estimated $3,480, and saves about $1,465 a year in heating and cooling — a payback around 2.4 years. Few home upgrades pay back that quickly.

The breakdown behind the number

Heating accounts for about $1,358/year of that and cooling about $106/year — Pulaski County needs both. Nationally, Pulaski County ranks in the 50th percentile for insulation savings potential. Compared only against its own climate zone, Pulaski County places 248th out of 825. Against Virginia's own average of $1,342/year, Pulaski County runs 9% above that.

The climate data behind this

The heating and cooling degree days behind this estimate — 5,079 HDD and 663 CDD (base 65°F, 1991-2020 normals) — come from PULASKI 2 E, VA US, the nearest NOAA station with published normals, 3.9 miles from Pulaski County's center. Combined heating and cooling load puts Pulaski County in the 46th percentile of this 3,162-county dataset. Its moisture regime is classified humid, which matters for whether the attic needs a vapor retarder as part of the job — worth asking a contractor about locally.

If the attic isn't bare

A shallower starting point changes the math: with R-11 already down, only the gap to R-49 needs filling, at roughly $2,280 for an estimated $214/year saved (~10.7-year payback). Whether that is worth it depends on how long you plan to stay.

Next steps for a Pulaski County attic

Actual quotes will vary by attic access, existing debris, and whether the job needs air sealing first. Treat the $3,480 figure above as a planning number for Pulaski County, not a bid - contractors typically charge a $600 minimum regardless of job size.
