Is the price difference a dealbreaker?
That 3% 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
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
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
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
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.
Rare among home projects, insulation punishes the half-measure — the money saved by under-insulating or skipping the air-seal comes back as higher bills. Meet the DOE R-value for your zone, seal the leaks first, and use the rebates on the table.
