Is the gap worth worrying about?
That 3% 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 area: Irving vs San Antonio
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 | Irving | San Antonio |
|---|---|---|
| 500 sq ft | $900–$2,400 | $850–$2,350 |
| 1,000 sq ft | $1,500–$3,950 | $1,450–$3,900 |

| 2,000+ sq ft | $2,800–$6,450 | $2,700–$6,300 |

What insulation pros earn in each metro
Since labor accounts for around 55% of what a spray foam insulation job costs, it's the biggest lever behind any price gap between cities. What you're seeing below is actual BLS metro wage data for skilled installers — not a guess.

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 rebate case
Few home projects come with rebate support like insulation does — utility and state programs routinely offset a meaningful slice of the bill (the federal 25C credit closed in December 2025). Run your address through DSIRE first, and book when a program's yearly budget has just refilled.
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.
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.
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.

Do insulation pros really charge more in one city?
It's not a myth — BLS data puts installer wages at about $29.7/hr in the Dallas-Fort Worth-Arlington area and $28.4/hr in San Antonio-New Braunfels. Given labor is around 55% of a spray foam insulation job's cost, that gap explains most of the price spread.
When is the cheapest time to buy spray foam insulation — and does it differ by city?
It doesn't vary by location — Spring and summer is the discount window in both Irving and San Antonio (roughly 5–10% off), while the pre-winter fall rush tends to be the most expensive in either city.
Should I choose where to live based on spray foam insulation cost?
Rarely. The $100 difference is real but one-time, and you can often close most of it in Irving by buying in the off-season and getting tighter, apples-to-apples bids. Ongoing factors — energy prices, climate and home condition — matter more over the life of the system.
