Spray foam insulation by type: Jacksonville vs Kendall
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.
| Type | Jacksonville | Kendall |
|---|---|---|
| Open-cell | $1,450–$4,350 | $1,450–$4,400 |
| Closed-cell | $2,400–$6,800 | $2,450–$6,850 |

Spray foam insulation by area: Jacksonville vs Kendall
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 | Jacksonville | Kendall |
|---|---|---|
| 500 sq ft | $850–$2,300 | $900–$2,350 |
| 1,000 sq ft | $1,450–$3,850 | $1,450–$3,900 |

Cheapest time for spray foam insulation in either city
Demand for insulation spikes every fall as winter approaches, pushing prices with it. Spring and summer avoid that crowd, and utility rebate pools are frequently still fresh 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 air-sealing case
Skip air-sealing and you're insulating around the very holes letting conditioned air leak out. Caulk, foam and weatherstripping are inexpensive and often return more felt comfort than a thicker blanket of insulation ever would — insist the crew handles the leaks before they bury them.
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 carries some of the strongest incentive money in remodeling, with utility and state rebates covering a real portion of the cost since the federal 25C credit expired at the end of 2025. Look up what applies on DSIRE, then schedule the work while rebate funds are still unclaimed for the year.
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.
