Rebates & incentives
Insulation and air-sealing lost their federal tax credit in 2026, but rebates and free-weatherization programs still cut the cost — especially for lower-income households.
- The federal 25C tax credit (which covered up to $1,200/yr of insulation and air-sealing) ended December 31, 2025 under the One Big Beautiful Bill Act — not available for 2026.
- IRA Home Electrification & Appliance Rebates (HEAR): up to $1,600 toward insulation, air-sealing and ventilation for households under 150% of area median income, where the state program has launched.
- IRA HOMES rebates: up to $8,000 for whole-home efficiency retrofits that hit modeled energy-savings targets.
- Weatherization Assistance Program (WAP): free insulation and air-sealing for households at or below 200% of the federal poverty level.
- Many gas and electric utilities offer their own insulation rebates — check the DSIRE database and your provider.

Why a quote looks high (or low)
- Material (blown-in, batt, spray foam) changes price sharply.
- Air-sealing may be included or quoted separately.
- R-value target varies — a bid to a lower R-value will look cheaper.
Get an apples-to-apples bid
- Ask about utility rebates and who handles the paperwork.
- Confirm removal of old insulation if needed.
- Match the target R-value to the DOE recommendation for your zone.
- Ask whether air-sealing is included or extra.
Questions to ask Lexington-Fayette Insulation pros
The only honest way to compare is to hold every quote to one checklist. Start with these.
- 1Did you do (or recommend) a blower-door test to find air leaks first?
- 2What R-value are you targeting, and is it the DOE recommendation for my zone?
- 3Is air-sealing included, or just the insulation material?
- 4Is removal of old/damaged insulation included if needed?
- 5Are there utility or state rebates I qualify for, and do you handle the paperwork?

What affects attic insulation cost the most?
Insulating an attic to cut heating and cooling loss — blown-in, batt or spray foam. That's the baseline — the price moves from there. Your mixed climate zone plays a part, but equipment/material grade, the size and complexity of the home, and local labor rates weigh in just as heavily.
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 R-value case
Insulate to the DOE recommendation for your climate zone — under-insulating to save money leaves comfort and energy savings on the table that would have paid the job back.
The air-sealing case
Insulation without air-sealing underperforms. Sealing leaks first is cheap and often delivers more comfort per dollar than thicker insulation alone — make sure it's in the scope.
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.
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.
