Upshur County, TX Insulation Payback
Upshur County, TX: what topping up your attic actually costs
Upshur County, Texas is zone 3 under DOE's climate map (Hot-Humid), which means summers that stay hot and humid while winters barely register on 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 2.7 years at an estimated $1,058/year saved. That's about as fast as attic paybacks get.
The breakdown behind the number
The estimated savings split roughly $726/year heating, $331/year cooling. Out of every 100 US counties tracked here, Upshur County's savings potential beats roughly 21 of them. Within zone 3 specifically, it ranks 340th of 690 counties by estimated savings. Texas averages $1,035/year across the counties tracked here; Upshur County comes in 2% higher.
Where these numbers come from
The heating and cooling degree days behind this estimate — 2,737 HDD and 2,080 CDD (base 65°F, 1991-2020 normals) — come from GILMER 4 WNW, TX US, the nearest NOAA station with published normals, 6.4 miles from Upshur County's center. By total degree days, Upshur County sits at the 20th percentile nationally. Upshur County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
Already have some insulation?
If Upshur County's attic already has 3-4 inches of old insulation (about R-11) rather than bare joists, the recommended target drops to R-38. That smaller top-up costs around $1,620 and saves an estimated $142/year — payback about 11.4 years. This one is a genuine toss-up, not a clear yes.
Getting it done in Upshur 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 Upshur County job, not a quote. Expect at least a $600 minimum charge from most contractors.
Nothing here is a guess
Every figure on this page traces to DOE/IECC climate zones and NOAA degree-day normals, documented in the methodology guide. The guide to what R-value actually means explains why R-49 is the target here specifically.
