How much should this gap actually matter?
A 11% gap is meaningful on a project this size — about $450. That's real money, but it's often within reach of off-season timing and a tighter apples-to-apples bid in Denver.
Attic insulation by type: Denver vs Greeley
We localize each attic insulation type separately for both metros, applying the same labor, climate and permit adjustments each time, so you're comparing like for like.
| Type | Denver | Greeley |
|---|---|---|
| Fiberglass batts | $1,750–$4,650 | $1,600–$4,200 |
| Blown-in fiberglass | $1,750–$5,250 | $1,600–$4,750 |

Attic insulation by area: Denver vs Greeley
Attic insulation is priced by the square foot of attic floor, typically $1–$7 per sq ft installed depending on material and how deep you build the R-value. Blown-in is cheapest; spray foam costs the most.
| Size | Denver | Greeley |
|---|---|---|
| 500 sq ft | $800–$2,550 | $750–$2,300 |
| 1,000 sq ft | $1,400–$4,100 | $1,250–$3,700 |
| 1,500 sq ft | $2,100–$5,850 | $1,900–$5,250 |
| 2,000+ sq ft | $2,800–$7,600 | $2,500–$6,850 |

What insulation pros earn in each metro
Labor is about 55% of a attic insulation bill, so local wages drive most of the gap. These are real metro hourly wages for skilled installers (BLS OEWS), not estimates.

Cheapest time for attic insulation in either city
Demand for insulation spikes every fall as winter approaches, pushing prices with it. Spring and summer avoid that crowd, and utility rebate pools are frequently still fresh that early in the year.
How much insulation is worth paying for?
Three choices shape an insulation budget — target R-value, whether air-sealing is included, and material type. Our editors weigh how each affects payback.
The air-sealing case
Blown-in or batt, insulation can only slow the heat that isn't already escaping through gaps and penetrations. Sealing those leaks costs little and frequently buys more comfort per dollar than piling on extra R-value, so confirm it's written into the scope.
The R-value case
Insulate to the DOE recommendation for your climate zone — under-insulating to save money leaves comfort and energy savings on the table that would have paid the job back.
The rebate case
Few home projects come with rebate support like insulation does — utility and state programs routinely offset a meaningful slice of the bill (the federal 25C credit closed in December 2025). Run your address through DSIRE first, and book when a program's yearly budget has just refilled.
Don't half-do an insulation job to save money upfront: seal the air leaks first, insulate to the DOE target for your zone, and stack the rebates. The full scope pays back faster than the partial one.
