PSE offers rebates on attic, wall, floor, and crawlspace insulation and air sealing for Whatcom County homes, and for an under-insulated house they can cover a real chunk of the job. As of 2026, the insulation rebates are structured per square foot, tied to bringing each assembly up to a target R-value, with a cap per area. The exact amount depends on your home, how much insulation it needs, and what you are starting from. The single most important rule: the work generally has to be done by a contractor in the PSE trade-ally network and sized to qualify, so the rebate is something you plan into the job from the start, not an afterthought.
What qualifies for a PSE insulation rebate.
PSE's residential weatherization rebates generally cover these measures for electrically or gas heated homes in their service area, which includes Whatcom County:
- Attic insulation, bringing the attic up toward R-49 from a lower starting point
- Wall insulation, adding insulation to under-insulated or empty walls
- Floor insulation, bringing the floor over a crawlspace up toward R-30
- Air sealing, which is often required as part of the insulation work and can carry its own incentive
The rebates are tied to the R-value improvement and the area insulated, and as of 2026 there is a square-footage cap per area. Because the amounts and the exact rules change, we confirm the current numbers for your specific home at the assessment rather than quoting a figure that might be out of date.
How much you actually get back.
The rebate scales with how much insulation your home needs and how far below the target it starts. A home with a nearly bare attic getting brought up to R-49 captures more than a home that just needs a small top-off, because the improvement is bigger. The rebate is generally applied per square foot, so a larger attic or floor captures more, up to the cap. For many Bellingham homes, the rebate brings the out-of-pocket on a typical attic or crawlspace job down meaningfully. We show you the real number for your house, not an inflated promise.
The rebate rewards the size of the improvement. The more under-insulated your home is to start, the more the rebate tends to be worth.
The trade-ally rule that trips people up.
The most common reason a homeowner misses out on a PSE rebate is doing the work themselves or hiring a contractor who is not in the PSE trade-ally network. To get the instant rebate, the installation generally has to be done by a participating contractor who deducts the rebate from your invoice, which lowers your out-of-pocket directly. This is exactly how we set up our jobs: we size the work to qualify, handle the rebate paperwork, and apply it to your invoice. You do not chase a check after the fact.
Air sealing: the two-for-one.
Air sealing is often required before or alongside the insulation, and it can carry its own incentive on top of the insulation rebate. That is part of why air sealing is such good value here, it saves the most on your heating bill and it helps unlock the insulation rebate. We seal first, then insulate, then file for both.
Beyond PSE: weatherization assistance.
For income-qualified Whatcom County households, there are deeper weatherization assistance programs, often run through the local community action agency, that can cover insulation and air sealing at little or no cost. These are separate from the standard PSE rebate and have their own eligibility rules. If you think you might qualify, it is worth asking about at the assessment, because the savings can be substantial.

Frequently asked questions.
How much is the PSE insulation rebate in Bellingham?
It depends on your home and how much insulation it needs. As of 2026, PSE's insulation rebates are structured per square foot, tied to bringing the attic, walls, or floor up to the target R-value, with a cap per area. A more under-insulated home captures more. We confirm the current amount for your specific house at the free assessment, since the figures change.
Do I have to use a specific contractor to get the PSE rebate?
Generally yes. To get the instant rebate deducted from your invoice, the work usually has to be done by a contractor in the PSE trade-ally network. We are set up to size the job to qualify, apply the rebate to your invoice, and file the paperwork, so you do not have to chase it yourself.
What insulation work qualifies for a rebate?
Attic, wall, floor, and crawlspace insulation and air sealing generally qualify for PSE rebates in Whatcom County, tied to bringing each assembly up to the target R-value. Air sealing is often required as part of the work and can carry its own incentive. We size the whole job to capture what is eligible.
Can I get a rebate if I already have some insulation?
Often yes, as long as you are below the target and the work brings you up to it. The rebate is tied to the improvement, so a home that starts with a thin, settled attic and gets brought up to R-49 still qualifies. A home already at or above the target generally would not, because there is no improvement to reward. We measure what you have and tell you straight.
