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
Fall is when everyone rushes to insulate before winter hits, making it the busiest and priciest season. Spring and summer see far less demand — and utility rebate budgets are often still full that early in the year.
How much insulation is worth paying for?
Insulation is priced on more than thickness. Target R-value, the presence or absence of air-sealing, and the material itself each pull the number in a different direction, and each changes how fast the job pays for itself.
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
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.
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.
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.
