Is the gap worth worrying about?
A 8% difference on spray foam insulation is minor — you'll typically see a wider spread just from getting multiple quotes in the same city, so don't let location drive the decision.

Cheapest time for spray foam insulation in either city
Demand for insulation spikes every fall as winter approaches, pushing prices with it. Spring and summer avoid that crowd, and utility rebate pools are frequently still fresh that early in the year.
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 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.
Hit the DOE R-value for your zone, air-seal first, and stack the rebates. Insulation is one of the few upgrades where doing it fully is also the cheapest path to payback.
