# DTE Energy Rebates for Spray Foam in Michigan: What Detroit Area Homeowners Can Claim in 2026
The February 2025 cold snap that hit Metro Detroit hard — eleven consecutive days in single digits — left a lot of Dearborn bungalows and Grosse Pointe colonials running furnaces around the clock. If your DTE Energy bill spiked past $400 that month, you were not alone. And if that bill still stings, there is real money on the table right now through DTE’s 2026 rebate program that most homeowners in Wayne, Oakland, Macomb, and Washtenaw counties have no idea exists.
Spray foam is one of the few insulation types that qualifies on both the air sealing and insulation sides of the program simultaneously — which is why it tends to pencil out better than batts or blown-in cellulose once you factor in what you can actually recover.

## What DTE’s Home Energy Efficiency Program covers
DTE serves most of southeast Michigan. If your gas or electric service comes from DTE, you are in the program zone.
For 2026, the two rebate categories most relevant to spray foam work are:
– **Air sealing**: Up to $400 when the contractor documents a measurable reduction in air leakage via blower door test before and after the work
– **Attic insulation**: Up to $600 for bringing an attic up to R-49 or higher
A home that gets closed-cell foam in the attic deck and rim joist area — common in the older two-story brick homes throughout Livonia, Westland, and east Dearborn — can claim both in a single project. That is $1,000 back from DTE before the federal side enters the picture.

## How to actually qualify
### Get the energy assessment before any work starts
DTE will not pay a rebate on work completed before a pre-inspection. Full stop. You need an energy assessment first. DTE runs a network of program partners who offer this, and in many cases the assessment itself is subsidized — you may pay $100 or less for a full blower door test, combustion safety check, and thermal imaging walkthrough.
You can also hire a private auditor who holds Building Performance Institute (BPI) analyst credentials. But call DTE to confirm your auditor is recognized by the program before you schedule. Some Oakland County homeowners have hit delays when their private auditor did not satisfy the program administrator’s requirements, and by the time that got sorted out, the project was already done.
### What your contractor has to give you
This is where rebate claims die. DTE requires the contractor to submit a documentation package — not just an invoice. That package needs:
– Pre- and post-installation blower door test results (ACH50, before and after)
– Product data sheets for the spray foam, including R-value per inch
– Installation photos showing coverage area and depth
– A signed contractor attestation matching the work scope to the pre-inspection findings
Ask your contractor directly before signing anything: “Have you submitted DTE Home Energy Efficiency Program packages before?” If they look uncertain, that is worth knowing now rather than after the job is done.
### Submit within 90 days
DTE has a submission window. If you miss it, you lose the rebate. Ask your contractor to hand you the full documentation package before they leave the job, not three weeks later when you are chasing them by email.

## Stacking the DTE rebate with the federal 25C credit
The Section 25C tax credit under the Inflation Reduction Act runs through 2032. For 2026, it pays 30% of qualifying insulation material costs, up to a $1,200 annual cap. It applies to materials only — not labor — so your contractor’s invoice needs to break those out separately.
Here is a real Wayne County example with actual numbers. A 1,500 square foot ranch in Taylor with an unconditioned attic and drafty rim joists gets 4 inches of open-cell foam across the attic deck and 2 inches of closed-cell on the rim joists. In this market, that project quotes somewhere between $4,800 and $6,200 depending on access and prep. Say the material breakdown comes in at $3,000. Your 25C credit is $900. Stack that against the $1,000 DTE rebate and your effective cost drops by $1,900 on a project that was north of $5,000.
Homes that were leaking badly enough to qualify for that air sealing rebate tend to see $600 to $900 per year in combined heating and cooling savings after the work. You will not recover the full cost overnight. But it is not a losing proposition either, especially when a lot of Downriver homes are burning through that in a couple of bad winters.
Keep your itemized invoice. Your tax preparer needs the material cost separated from labor to calculate the 25C correctly.

## If DTE does not serve you
DTE does not cover all of Michigan. If you are in Grand Rapids, Kalamazoo, or Lansing, your utility is Consumers Energy, and they run a parallel program through their own contractor network. The rebate structure is similar, but the dollar amounts and documentation requirements differ. Consumers Energy also has an online pre-application portal that lets you get preliminary approval before scheduling your assessment — something DTE does not currently offer. The federal 25C credit works the same either way.

## FAQ
**My Macomb County home was built in the 1970s. Does that hurt my eligibility?**
No. DTE’s program is open to existing homes regardless of age. Homes from that era were built under different codes with almost no intentional air sealing, so they often show the largest measurable improvement from spray foam work. That actually helps your rebate documentation — the blower door delta is usually significant enough that there is no ambiguity about whether the work moved the needle.
**Can I claim the DTE rebate and the 25C credit in the same year?**
Yes. They are completely independent. DTE processes the rebate on their end and sends a check, typically 6 to 10 weeks after submission. The 25C credit gets claimed on your federal return (Form 5695) based on material costs, and the rebate does not reduce the figure you use for that calculation.
**My contractor is not on DTE’s partner directory. Can I still get the rebate?**
Yes. The rebate does not require you to use a DTE-listed contractor — it requires the work to meet program specs and the documentation package to be complete. Any contractor who understands the requirements can submit the package. The practical difference is that contractors who have done it before tend to submit cleaner packages that do not bounce back for corrections, which speeds up your check.
**Does spray foam in a crawl space qualify?**
It can, under the air sealing category. But the rebate is calculated on verified ACH50 improvement across the whole house envelope, not the crawl space alone. Your pre-inspection assessment will tell you how much your crawl space is contributing to your total air leakage. In older Downriver homes with unencapsulated dirt crawl spaces, it is usually a meaningful contributor — and treating it typically does move the whole-house number enough to satisfy the program threshold.
