How much should this gap actually matter?
A 6% 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
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?
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 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.
The rebate case
Few home projects come with rebate support like insulation does — utility and state programs routinely offset a meaningful slice of the bill (the federal 25C credit closed in December 2025). Run your address through DSIRE first, and book when a program's yearly budget has just refilled.
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.
Air-seal before you insulate, hit the DOE-recommended R-value for your zone, and claim every rebate you're eligible for — insulation is a rare case where doing the full job is also the cheapest one, long-term.

Should I choose where to live based on spray foam insulation cost?
