Is the price difference a dealbreaker?
That 5% 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.

What insulation pros earn in each metro

Cheapest time for spray foam insulation in either city
Everyone waits until fall to insulate, which is exactly why fall costs the most. Spring and summer are quieter for installers and often catch a fresh year's rebate budget before it runs dry.
How much insulation is worth paying for?
Insulation is one of the few home upgrades where spending more can genuinely pay for itself. Our editors on the choices that decide both cost and payback.
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
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.
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.
