Is the gap worth worrying about?
A 3% 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
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?
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
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.
The R-value case
The DOE publishes a target R-value for every climate zone, and there's a reason to reach it: stopping short shaves a little off install day but forfeits years of lower energy bills and steadier indoor temperatures. Under-insulating is the one shortcut here that never actually pays.
The rebate case
Insulation carries some of the strongest incentive money in remodeling, with utility and state rebates covering a real portion of the cost since the federal 25C credit expired at the end of 2025. Look up what applies on DSIRE, then schedule the work while rebate funds are still unclaimed for the year.
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.
