Federal Insulation Tax Credits

There are Tax Breaks for Insulation, But For a Limited Time Only!

Upgrading your home’s insulation or sealing up energy-wasting air leaks? Right now, you could qualify for up to $1,200 in federal tax credits.

UPDATE: Time is running out. Congress passed a bill in July 2025 that ends the tax credit early, at the end of this year. That means you only have a few months to complete your upgrades and claim your credit.

At Evergreen Home Performance, we make it easy to not only improve your comfort and lower your energy bills, but also maximize the financial incentives available to you.

How the Insulation Tax Credit Works

The insulation tax credit (formally known as the Energy Efficient Home Improvement Credit or 25C) covers 30% of the cost of qualifying home upgrades, up to a maximum of $1,200 for insulation and air sealing.

It’s available now for all upgrades completed by December 31, 2025.

You can combine this credit with other incentives like Efficiency Maine rebates to stack your savings even higher..

How to Claim the Insulation Tax Credit in Maine

A tax credit reduces the amount of taxes you owe when you file—they are a different kind of incentive than a rebate, where you receive a direct check or upfront discount.

Efficiency Maine and the IRS are both good resources for homeowners looking to take advantage of this tax credit:

For personalized guidance tailored to your specific circumstances, we recommend consulting with your tax professional. They can assist you in assessing your eligibility and accurately calculating the credit based on the scope of work and invoice provided by us.

I highly recommend Evergreen! 1st, I had a home efficiency inspection (that was free) & Bryan P. was great! He took the time needed, asked & listened to what I thought were priorities, explained clearly what he thought were priorities & why, then gave me numerous options. No pressure whatsoever. Then I had my attic sealed & insulated as the 1st step & Bryan came along on day 1 to introduce everyone & make sure we were all on the same page. Bruce's team (inc. Kelsey & Roland) did the work - they were exceptional!!

Professional, friendly and hard-working staff. The product/approach they use for insulation is top notch. We felt the difference immediately, both from added warmth and eliminating drafts. The team and management were easily available to answer our questions or coordinate meeting times. Highly recommended.

The Evergreen crew who installed insulation in my attic were fantastic! They were very professional, worked exceedingly hard, and they did an excellent job. They were very pleasant and friendly to be around. They cleaned up beautifully after each work day, and left my home in great shape on when they walked out the door for the last time. I can't believe they were able to accomplish all that they did with heat soaring into the 80s and 90s. It was pretty unbearable up there! They have my highest praise and my gratitude.

We absolutely loved our experience with Evergreen. The team was incredibly kind, professional and great to work with. We're very impressed with the quality of work of the Evergreen team and how easy they made everything! Our house had barely any insulation ahead of this project and the results are amazing. Insulating the attic, walls and basement with Evergreen allowed us to tear a 50-year-old furnace, ductwork and oil tank out of the basement and now heat the home with new heat pumps. Evergreen also added 100 sq ft of clean, new storage space to the attic!

I have always been impressed by the high level of service, quality of work, and excellent follow-through provided by Evergreen Home Performance in the three projects that they completed at the Wells Reserve at Laudholm over the past several years.

Evergreen has just completed Phase 2 of 2 at my home. They are professional, hard-working and courteous. They communicate well..no surprises. They've gone above and beyond to make my home comfortable and were very respectful of my home.I recommend them unequivocally!!!Many thanks to Brian, Brian, Rick, Eddie, Dawson and the rest of the Evergreen crew!!

I used to spend winters in the bathtub because my house was so cold. This was my first winter roaming around my whole house comfortably. This even led me to decorate a little. My heating oil usage has been reduced by over a quarter: I rarely have to boost the thermostat because the temp stays at a constant. The Efficiency Maine rebates, together with the energy savings, make it affordable for me to pay for the loan I took out to finance the project. I do not worry about my pipes freezing.

Last week, my oil company asked if we were using some other kind of fuel because our usage was so much less than they had expected We are very happy with the results; the house is much more comfortable

Our basement was the eyesore of the house. I wanted to make improvements, but first needed to make structural, insulating and moisture mitigation improvements. Evergreen was professional and competent in taking on a complex project of not only encapsulation and insulation of basement and crawlspace, but completed needed improvements to the structural integrity of the wood floor platform above a crawlspace and brought in a concrete contractor to pour where there was once a rotting, tiered wood platform - replacing that area with a more functional and tight tiered concrete area.

Bryan, Dave and the entire Evergreen team are wonderfully professional, prompt and thorough. I enjoyed working with them and look forward to continued work as we upgrade our home! Thank you so much for your professionalism, fairness, time and diligence.

I am very pleased with my experience with Evergreen Home Performance. I met several times with Richard Burbank and he was very detailed in his explanations to all of my questions. He provided me with several options for improving the insulation to our home. The team of installers were very professional and respectful of our home. They did a great job of cleaning up every day after the days work and they were also very responsive to all my questions as well as we collaborated to get our home better insulated. It was a pleasure to work with Richard and…

We had Evergreen redo the insulation in our roof. The team handling our project did a great job. They left the house spotless. We've already noticed the difference in how much better our house is retaining heat. I would definitely recommend and will use them for future projects.

We couldn't be more pleased with the easy, professional, high-value service from Evergreen. Having purchased an older home that had been in our family for generations, we needed multiple upgrades, including insulation throughout. Evergreen insulated our attic with blown-in cellulose, built a new, super-insulated attic hatch, sealed off the old one (which was just a piece of plywood in a closet ceiling), and also talked us through our best options to upgrade our heating system given the plans we have to add onto the house.
