Quality work at a fair price, guaranteed

Back to Blog

Inviting a contractor into your home requires trust. You’re making decisions about comfort, health, energy use, and long-term value. 

You deserve to feel confident that you’re being treated fairly every step of the way.

At Evergreen Home Performance, two commitments guide how we work with homeowners across Maine: fair, transparent pricing and a promise to make things right if you’re not satisfied with the outcome.

Here’s what that means in practice.

Our apples-to-apples price match guarantee

Home performance work is rarely one size fits all. The scope of work, materials, installation details, and quality standards can vary widely from one proposal to the next.

That’s why Evergreen offers an apples-to-apples price match guarantee.

If you receive a written proposal from another Efficiency Maine participating contractor for the same scope of work, using comparable materials and methods, we’re happy to review it. If it is truly the same work at a lower price, we’ll match it.

What we typically find is that once homeowners look more closely, the work isn’t actually identical. Insulation depth, air sealing details, materials, and quality controls often differ in meaningful ways. Still, this guarantee gives you peace of mind that you’re getting quality work at a fair price, without cutting corners.

Our commitment to making things right

We’re careful about using the phrase “satisfaction guaranteed” because every home and project is unique. What we can say, and fully stand behind, is this:

If you’re not satisfied with our work, we’ll do what we can to make it right.

That starts with listening. It means revisiting the work, addressing concerns, and standing behind what we install. Our goal isn’t just to complete a project. It’s to deliver results that align with what we promised and what you expected.

This approach reflects how we’ve operated since 2006 and why thousands of Maine homeowners continue to trust Evergreen with their homes.

Built on trust, not pressure

These commitments aren’t marketing gimmicks. They’re extensions of how we approach every project: clear communication, careful assessments, and respect for your goals.

If you’re considering an energy audit, insulation, or basement waterproofing and want to work with a team that values fairness and accountability, we’re here for you.

A thorough inspection of our (older) house and its energy needs. Competent and personable work crew.

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…

This team of individuals was professional at all times. They set up barriers that kept the dust at a minimum. They conducted an air flow audit and cut the draft circulation from the outside in half by sealing cracks. They hauled out the old insulation and replaced it with blown in insulation with an R - 60 Value. They also did the rebate paperwork so that I could get my $1500.00 rebate from the state of Maine. I highly recommend Evergreen Home Performance!

Evergreen completed the work at my home thoroughly and professionally. An inspector from Efficiency Maine came to inspect afterwards and described it as "state of the art" and "outstanding". The crew was very pleasant and considerate during the project. Their cleanup each day was perfect. Communications with the office were easy and reliable. I am very satisfied.

Thanks Evergreen Home Performance for helping to make our home more efficient. Many thanks as well to Bryan for the initial walk through and recommendations to make our home more efficient and to Dave, Roland, and Jacob for a job that was done professionally and courteous.  We were amazed at the level of efficiency and everyday they made sure to protect our floors, carpets, and furniture. We had daily discussions with Dave about progress and what was being done and where they were at in the project.

Update 12/2018: Evergreen has completed Phase II of my house (insulating and installing air/moisture barrier on exterior walls, replacing old windows) and now that heating season is upon us, the difference is astonishing. The house is tight as a drum and so easy to keep warm. Worth every penny. Thank you all! Working with Evergreen was a positive experience from start (no charge energy audit) to finish (a MUCH more comfortable home). Brian Robinson spent a lot of time with me on the audit, explaining clearly what he was finding in my ca.

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!

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.

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.

Great job installing windows and insulation.

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.

Great team!

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 was a dream! Professional, knowledgeable, and super clean work. Communication was fast and service impeccable. The bedroom floors in our 1960's split ranch will be warm with the new insulation between them and the garage. Bring on the snow! (not really, but sort of)

Working with Brian and with Nate and the rest of the crew was a pleasure. They made everything very easy and understandable. This was a major renovation and they were always at the ready with a lot of information. We had an extensive renovation on the basement which was a dirt basement and it came out beautifully. We can already tell from all of the insulation work what a difference it's made in sound and temperature. Brian worked with me on the rebates that are available when you do this kind of work. I would highly recommend this company to…
