How much should this gap actually matter?
That 4% 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
Because most homeowners wait for the fall pre-winter panic, that's when prices peak. Getting it done in spring or summer means less competition and, often, an untapped rebate budget.
How much insulation is worth paying for?
Where an insulation budget lands depends less on square footage than on three calls — the R-value you target, whether air-sealing rides along, and which material fills the cavity.
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
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 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.
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.
