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?
R-value, air-sealing and material decide both the price and the payback. Our editors on the trade-offs.
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 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 rebate case
Insulation carries some of the strongest incentive money in remodeling, with utility and state rebates covering a real portion of the cost since the federal 25C credit expired at the end of 2025. Look up what applies on DSIRE, then schedule the work while rebate funds are still unclaimed for the year.
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.
