Is the price difference a dealbreaker?
That 8% 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.
Attic insulation by type: Columbus vs Hamilton

What insulation pros earn in each metro

Cheapest time for attic 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
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.
Don't half-do an insulation job to save money upfront: seal the air leaks first, insulate to the DOE target for your zone, and stack the rebates. The full scope pays back faster than the partial one.
