Best time to buy

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.

Editors' roundtable

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

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 air-sealing case

Skip air-sealing and you're insulating around the very holes letting conditioned air leak out. Caulk, foam and weatherstripping are inexpensive and often return more felt comfort than a thicker blanket of insulation ever would — insist the crew handles the leaks before they bury them.

The rebate case

Insulation has some of the best rebate math in home improvement — utility and state programs can cover a solid share (the federal 25C credits ended Dec 2025). Check DSIRE before you book and time it to a fresh rebate budget.

Our take

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.
