Is the gap worth worrying about?
That 6% 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 insulates in fall before winter, so that's the busy, full-price season. Booking in spring or summer catches off-peak pricing — and utility rebate budgets are often freshest early in the year.
How much insulation is worth paying for?
Insulation is one of the few home upgrades where spending more can genuinely pay for itself. Our editors on the choices that decide both cost and 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 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
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.
Of every home upgrade, insulation rewards doing it right the most: air-seal first, meet the DOE R-value for your climate zone, and use the rebates on the table. Cutting the scope here just delays the payback.
