What insulation pros earn in each metro
Roughly 55% of what you pay for attic insulation is labor, which is why local wages explain most of the price gap. The numbers below are actual metro wages for skilled installers, sourced from BLS OEWS — not guesses.

Cheapest time for attic insulation in either city
Everyone waits until fall to insulate, which is exactly why fall costs the most. Spring and summer are quieter for installers and often catch a fresh year's rebate budget before it runs dry.
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 R-value case
Aim for the R-value the DOE assigns your zone, not a round number that sounds close enough. Every point you fall short is comfort you don't feel and utility savings you never bank — savings that would have covered the extra material several times over.
The air-sealing case
Insulation without air-sealing underperforms. Sealing leaks first is cheap and often delivers more comfort per dollar than thicker insulation alone — make sure it's in the scope.
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.
Rare among home projects, insulation punishes the half-measure — the money saved by under-insulating or skipping the air-seal comes back as higher bills. Meet the DOE R-value for your zone, seal the leaks first, and use the rebates on the table.
