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 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.
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.
What makes insulation unusual is that the thorough version and the cheap version are the same version — seal first, meet the DOE R-value for your zone, and layer on the rebates. A partial job just pushes the payback date further out.
