Nicholas County, WV Insulation Payback
Attic insulation payback for Nicholas County, WV
Nicholas County sits in IECC climate zone 5 (Cold) — a real winter that drives most of the annual energy bill here. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-60. For an attic around 1,000 square feet, closing the gap from R-2 to R-60 costs around $3,480 and saves an estimated $1,551 a year — payback in roughly 2.2 years. Hard to find a home improvement with a faster payback than this.
Where the savings come from
Of that, about $1,455/year comes from reduced heating and $95/year from reduced cooling load through the ceiling. Nicholas County beats 56% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 745 counties DOE places in zone 5, Nicholas County ranks 693rd. Against West Virginia's own average of $1,526/year, Nicholas County runs 2% above that.
The climate data behind this
NOAA's SUMMERSVILLE LAKE, WV US station, 7.2 miles from Nicholas County, supplies the 5,443 HDD and 593 CDD this estimate runs on. Combined heating and cooling load puts Nicholas County in the 52th percentile of this 3,162-county dataset. DOE also classifies Nicholas County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
The smaller top-up scenario
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 $226/year saved (~10.1-year payback). It is close - the payback only just fits a reasonable timeframe.

Get more than one quote before committing. Attic access and any needed air sealing move the price around, and most contractors won't take a job below roughly $600 regardless of size - worth asking upfront given Nicholas County's estimated $1,551/year on the line.
