Is the price difference a dealbreaker?

What insulation pros earn in each metro

Cheapest time for attic insulation in either city
The fall insulation rush drives prices up because everyone's thinking about the coming winter at once. Book in spring or summer instead, when demand is lower and rebate funds haven't been claimed yet.
How much insulation is worth paying for?
Insulation is priced on more than thickness. Target R-value, the presence or absence of air-sealing, and the material itself each pull the number in a different direction, and each changes how fast the job pays for itself.
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.
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
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.
Air-seal before you insulate, hit the DOE-recommended R-value for your zone, and claim every rebate you're eligible for — insulation is a rare case where doing the full job is also the cheapest one, long-term.
