Is the price difference a dealbreaker?
4% is within noise for spray foam insulation — contractor selection and timing move the price more than which of these two metros you're in.
Spray foam insulation by type: Florence vs Montgomery
We localize each spray foam insulation type separately for both metros, applying the same labor, climate and permit adjustments each time, so you're comparing like for like.

Spray foam insulation by area: Florence vs Montgomery
Spray foam is priced by board foot (1 sq ft at 1 inch thick), which works out to about $1.50–$5 per sq ft of surface installed depending on foam type and thickness. Closed-cell costs more but adds twice the R-value per inch.
| Size | Florence | Montgomery |
|---|---|---|
| 500 sq ft | $850–$2,250 | $850–$2,300 |

Cheapest time for spray foam insulation in either city
The fall insulation rush drives prices up because everyone's thinking about the coming winter at once. Book in spring or summer instead, when demand is lower and rebate funds haven't been claimed yet.
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 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 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 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.
Payback is the whole point with insulation, and it arrives fastest when the job is done in full: air-sealing, the DOE-recommended R-value for your climate zone, and whatever utility rebates you qualify for. Trimming any one of those trims the return, not the cost.

When is the cheapest time to buy spray foam insulation — and does it differ by city?

Should I choose where to live based on spray foam insulation cost?
That would be a stretch. $150 is a one-time difference, not an ongoing one, and off-season buying plus apples-to-apples bids in Montgomery can close a good chunk of it. What matters more long-term is energy costs, climate and the condition of the home.
