The verdict

Is the price difference a dealbreaker?

That 3% gap is small — for attic insulation it's usually less than the spread between two local contractors' quotes, so the metro matters far less than who you hire and when you 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?

How much you spend on insulation and how fast it pays back come down to R-value, air-sealing and material. Our editors break down the trade-offs.

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 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.

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.

Our take

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.
