How much should this gap actually matter?
That's a real $300 difference (9%) on spray foam insulation — worth factoring in, though off-season timing and a tighter quote in San Antonio can narrow it.
Spray foam insulation by type: McKinney vs San Antonio
Every spray foam insulation type gets its own localized price for each metro, using the same labor, climate and permit adjustments — a true apples-to-apples comparison.
| Type | McKinney | San Antonio |
|---|---|---|
| Open-cell | $1,350–$4,050 | $1,450–$4,350 |
| Closed-cell | $2,250–$6,250 | $2,450–$6,800 |
Localized 2026 planning estimates — not quotes. Each city adjusts the national spray foam insulation range for local labor, climate and permits.
Spray foam insulation by area: McKinney 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 | McKinney | San Antonio |
|---|---|---|
| 500 sq ft | $800–$2,150 | $850–$2,350 |
| 1,000 sq ft | $1,350–$3,600 | $1,450–$3,900 |

| 2,000+ sq ft | $2,500–$5,800 | $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
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?
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
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.
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.
What makes insulation unusual is that the thorough version and the cheap version are the same version — seal first, meet the DOE R-value for your zone, and layer on the rebates. A partial job just pushes the payback date further out.
