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.

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!!

David Henry Feldman

The Evergreen Team did a fabulous job, well exceeding our expectations, In just over a week they transformed our very drafty, noisy 213 year old house into a snug, draft-free, quiet haven with warm floors! The team was prompt, did everything they said they'd do and more. We are thrilled!

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

John Brown

First we have Evergreen do a BIG project worth about $20K (windows, basement, insulate & rebuild an entire wall, a door, attics, and air sealing). They were so great we had them come back later when we decided we did want to do our other door. They are professional and do great work. They take care of your home and are trustworthy, and on top of all that friendly! I highly recommend you call them!

Garreth C Debiegun

We had Evergreen energy do blow-in cellulose. I was very happy with the result. They tested with blower-door before and after. House is now MUCH warmer. Also, in the time since when I've had to open walls for various access, I've been impressed with how they got the insulation packed in everywhere. I'd use them again.

We just finished a large project of air sealing and reinsulating our 1890s basement and attic which 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.

Emily Gallant

Evergreen listened and produced a thoughtful evaluation, proposal and comprehensive plan for our attic and basement. They exhibited excellent workmanship, teamwork, and came back as planned after the completion of the job to test the outcomes. Their overall performance as insulation and home improvement contractors is truly outstanding and we highly recommend them.

The folks at Evergreen did a great job fixing a rather major insulation problem in my house, which they helped identify with a great audit. When the work began, they were thorough, upbeat, and -- dare I say it -- efficient. I strongly recommend them.

Michael Williams

Very easy process, start to finish.  Friendly, professional, and really know their stuff.  They made some improvements to our condo and we were very happy with how it played out.  Would definitely recommend them.

Clayton Eames

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.

I would recommend Evergreen wholeheartedly because of their professionalism, their follow through, and thoughtful project planning.

Jennifer A

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.

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

Michele

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.

Thorough, smart, informative, integrated, and communicative -- that's how my experience was with Evergreen even with the covid interruption midstream. The team picked up where they left off, insulated basement and air sealed attic and knee wall in 100' temps under the eaves! This business group was a pleasure to work with.
