Is the gap worth worrying about?
That 1% gap is small — for spray foam insulation it's usually less than the spread between two local contractors' quotes, so the metro matters far less than who you hire and when you buy.
Spray foam insulation by type: Dunwoody vs Savannah
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 | Dunwoody | Savannah |
|---|---|---|
| Open-cell | $1,450–$4,400 | $1,500–$4,500 |
| Closed-cell | $2,450–$6,900 | $2,500–$7,000 |

Spray foam insulation by area: Dunwoody vs Savannah
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 | Dunwoody | Savannah |
|---|---|---|
| 500 sq ft | $900–$2,350 | $900–$2,400 |
| 1,000 sq ft | $1,450–$3,950 | $1,500–$4,000 |

| 2,000+ sq ft | $2,750–$6,400 | $2,800–$6,500 |
Treat these as 2026 localized estimates for spray foam insulation, not quotes from a contractor.
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
Everyone waits until fall to insulate, which is exactly why fall costs the most. Spring and summer are quieter for installers and often catch a fresh year's rebate budget before it runs dry.
How much insulation is worth paying for?
Three choices shape an insulation budget — target R-value, whether air-sealing is included, and material type. Our editors weigh how each affects payback.
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 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.
Rare among home projects, insulation punishes the half-measure — the money saved by under-insulating or skipping the air-seal comes back as higher bills. Meet the DOE R-value for your zone, seal the leaks first, and use the rebates on the table.
