Is the gap worth worrying about?
That 1% gap is small — for attic 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.

Cheapest time for attic insulation in either city
Everyone insulates in fall before winter, so that's the busy, full-price season. Booking in spring or summer catches off-peak pricing — and utility rebate budgets are often freshest 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 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
Aim for the R-value the DOE assigns your zone, not a round number that sounds close enough. Every point you fall short is comfort you don't feel and utility savings you never bank — savings that would have covered the extra material several times over.
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.

Since labor is roughly 55% of a attic insulation job, that wage gap is the biggest reason the installed prices differ.

Should I choose where to live based on attic insulation cost?
Probably not. Yes, $50 is a real gap, but it's a one-time cost you can partly offset in Grand Prairie with off-season timing and tighter bids. Long-term factors like energy prices and home condition matter more than this one number.
