How much should this gap actually matter?

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 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
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
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.
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.
