How much should this gap actually matter?
That 1% gap is small — for spray foam 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 spray foam 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?
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
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 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.
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.
