Happy Evergreen Team Working On A Project Together

Why Mainers Trust Evergreen

Our process is simple, clear, and built around your needs:

Step 1: Understanding Your Home – and Your Goals

Before we talk upgrades, we listen.

During your free one-hour consult, an Evergreen Energy Advisor will:

  • Learn about your comfort, health, and energy concerns
  • Walk through your home – from basement to attic
  • Identify visible issues like air leaks, insulation gaps, and moisture problems

We focus on finding the root causes of your home’s problems, so that we can recommend long-lasting solutions.

If you decide to move forward, we’ll move right to a full home energy audit – a deep diagnostic evaluation using tools like blower door testing and thermal imaging. This gives us the data to build a custom, building-science-based plan for your home.

Step 2: Expert Upgrades, Designed for Lasting Results

Once we know what’s going on, we get to work fixing it—carefully, completely, and customized to your home.

Evergreen offers comprehensive solutions like:

Step 3: Measuring Your Success

We don’t just say your home is better. We prove it.

After upgrades are completed, we’ll:

  1. Retest and verify the improvements with diagnostic tools
  2. Confirm your home meets Evergreen’s quality and safety standards
  3. Check in to hear about the real, measurable impact you’re experiencing in your home

We love hearing from customers about how their homes feel after Evergreen upgrades! And we always appreciate when our customers tell their friends, neighbors, and Google about what it’s like working with our team.

Making It Affordable: Rebates and Financing

Home improvements should feel good for your wallet, too. When you work with Evergreen, we can help you:

  • Qualify for up to $8,000 in Efficiency Maine rebates
  • Finance the balance with payments as low as $50/month

We’ll guide you through every available rebate and financing option – handling the paperwork where possible and making it easy for you to take advantage of savings.

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.

Awesome company. It was a few years ago that they did the audit and then we commissioned them to do the work. We subsequently sold our house and moved to South Africa, but their level of service and expertise will live on.

Odette Brown

Our house still the most efficient home we’ve ever lived in. And we have you folks to thank for that! A special howdy to Brian Robinson please!

Bruce O’Donal and Eva Butler

Evergreen did an amazing job insulating our historic home. Their professional staff worked hard to ensure the tough areas in the attic were covered, and clearly communicated their progress. We are seeing the results with our discounted heating bills. Thank you, Evergreen!

I made the mistake of NOT hiring this company last year when I bought and renovated my home. I have brought them in now and what a difference. This group knows what they are doing. They take a complete look at everything and believe they can make your home more energy efficient. They are very professional in the way they approach problems and solutions. And they find ways to save me money. Don't bother with anyone else. Bring Evergreen in before you do anything. Let them assess your issues and give you the right solutions.

Really great experience from start to finish with Evergreen. They helped us prioritize what needed to be completed first, and has made a significant difference in our hearing costs already. Plus they were really friendly and considerate to work with!

Great job installing windows and insulation.

From beginning to end – that is from the moment Justin McEdward stepped into our home to assess our energy conservation needs until the crew left – the Evergreen Home Performance process went absolutely smoothly. Justin made a thorough inspection and took pictures with an infrared camera. His proposal described the scope of work in detail, and he explained what we could expect the proposed work to accomplish. Our proposal was forthcoming within a couple of days, and Justin was available to discuss it and answer questions.

Adrienne Harkavy

I never leave reviews, but had a great experience with Evergreen and wanted to spread the word! In short, we worked with them to insulate our roof this winter and have noticed surprising immediate results. The constant ice dams I have wrestled with are completely gone, and the home is noticeably more comfortable. It's a little too early to tell if our oil bill is going to reduce, but I imagine we will see an impact there as well.

I had gotten estimates from several other companies, but Evergreen was in another league entirely with their professionalism. If you want the job done correctly, I couldn't recommend this company enough.

Several years ago Brian Robinson evaluated the crawl space at my summer home on Islesboro where I knew moisture was becoming a problem. I had done quite a bit of work in the space many years prior with mixed results. When Brian offered some suggestions, they were ideas that incorporated work previously done, and would be a relatively low cost effort to improve the situation. He offered this advice over several phone conversations of some length, informally, and at no charge.

The Evergreen crew from initial inception to installation were professional, on time, and left our place spotless. The end result was exceptional.

John Brown

Evergreen removed and replaced the insulation in my attic. They did a great job!, Crew was excellent, and the whole thing went smoothly, and the attic was NOT easy to get into or work in, so kudos to some hard work done well!

Joel A.

Portland

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!

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.
