What insulation pros earn in each metro
Labor is about 55% of a spray foam insulation bill, so local wages drive most of the gap. These are real metro hourly wages for skilled installers (BLS OEWS), not estimates.

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?
R-value, air-sealing and material decide both the price and the payback. Our editors on the trade-offs.
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.
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 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.
Hit the DOE R-value for your zone, air-seal first, and stack the rebates. Insulation is one of the few upgrades where doing it fully is also the cheapest path to payback.
