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.

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

The Evergreen team was amazing from initial assessment and planning to the crew that came to complete the work. Our basement encapsulation is the best money we've spent on our house by far. The work was thorough and high quality. And what a wonderful group of people to work with. I highly recommend Evergreen!

Martha Bracy

Evergreen did a fantastic job insulating our 1930's home. The onsite team was professional, clean, and really just a joy to interact with throughout the process. A blower test at the end showed a significant decrease in air leakage. I highly recommend Evergreen.

Greetings one and all! I am writing to express my gratitude to all involved in my insulation project.  From start to finish, I appreciate the universal theme which was maintained by each and every one of you, to ensure that my home was insulated and protected from freezing pipes as if it was your home. Andrea, thanks for helping me navigate my way to the project. Nate, thanks for the thorough initial assessment and the time you took to explain this project to me, step by step. Brian, thanks for setting up my project - so happy

Evergreen came back this year to finish insulating our house. We have been remodeling and renovating an 1850s cape for several years. Their employees are very professional and pleasant to deal with. Over several years Brian Robinson has been able to schedule us in for several small areas that needed addressing and finally turning a room we used to close off in the winter into a comfortable usable space. We primarily heat with wood and since Evergreens great work our furnace has only come on ONCE this winter. Fantastic. Really satisfied customer in Thomaston.

Evergreen has a professional and reliable team of people who do excellent work. If you want the best of the best in the area, select Evergreen to accomplish your insulation needs.

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.

We needed basement encapsulation to stop moisture coming up into the house from our regularly flooding basement. We had mold growing on windowsills and furniture. All the staff were friendly, respectful of our home, and easy to work with. Humidity has gone from 70% down to 40% and mold has not grown back after two months. Very grateful.

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

John Brown

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.

The crew members from Evergreen Home Performance each made sure to greet us every day, while maintaining their distance in this time of the pandemic. Their work took a total of nine days, spread over three weeks. Even though they were working in multiple rooms of our house, as well as the basement and attic, they were unobtrusive and always cleaned up after themselves every day. The on-sight manager kept us informed of their daily schedule so we'd know which parts of the house they'd be working on.

From start to finish, our experience was incredible. Justin was extremely helpful. The crew was fast, friendly, and efficient. And most importantly, our home is WAY warmer and our heating is less costly. I'd highly recommend evergreen to anyone looking to upgrade their home!

"Working with Evergreen from start to finish was a great experience." See what our customers have to say about their experience with Evergreen Home Performance. 

Jeff L.

We just finished a large project air sealing and reinsulating our 1890s basement and attic. It had been completely renovated 8 years ago, but still felt cold, and lacked proper energy assessment and corrections. We met with Justin in December and were very impressed with his knowledge, professionalism and communication skills and knew Evergreen was who we wanted to work with. Dave was our on hands project manager and was excellent. The office staff has been quick to respond and helpful as well when needed.

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.
