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 attic insulation quotes vary — and how to compare them fairly

Why a quote looks high (or low)
- Material (blown-in, batt, spray foam) changes price sharply.
- R-value target varies — a bid to a lower R-value will look cheaper.
- Air-sealing may be included or quoted separately.
Get an apples-to-apples bid
- Compare the same material type across bids.
- Ask whether air-sealing is included or extra.
- Confirm removal of old insulation if needed.
- Match the target R-value to the DOE recommendation for your zone.
Questions to ask Burien 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. Where two homes diverge is in the details below. What moves the price most: equipment or material grade, your home's size and complexity, local labor rates, and the mixed climate zone.
How much insulation is worth paying for?
Insulation is one of the few home upgrades where spending more can genuinely pay for itself. Our editors on the choices that decide both cost and 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 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
Skip air-sealing and you're insulating around the very holes letting conditioned air leak out. Caulk, foam and weatherstripping are inexpensive and often return more felt comfort than a thicker blanket of insulation ever would — insist the crew handles the leaks before they bury them.
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.
