Is the price difference a dealbreaker?
That 6% 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?
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
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
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
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.
Don't half-do an insulation job to save money upfront: seal the air leaks first, insulate to the DOE target for your zone, and stack the rebates. The full scope pays back faster than the partial one.
