Our Process

Evergreen Home Performance is committed to helping Mainers create healthy, efficient homes. Our home performance projects improve comfort and indoor air quality, and can cut your energy bills by 25% or more! 

We start every project by looking at the big picture so we can find the root cause of your home's comfort, health, safety, and energy efficiency problems, and provide comprehensive solutions.

Our process helps us serve our community, employ talented and committed local professionals, and reduce emissions one house at a time, and we think you’ll agree that our commitment shows in our results.

What to Expect When You Hire Evergreen

When you hire Evergreen Home Performance for your home improvement project, we’ll be there to walk you through every step of the process. We take a step-by-step approach to ensure the best results for your home and budget.

Step 1: Evaluating Your Home's Energy Efficiency

Our two-phase home evaluation allows us to diagnose the key issues in your home so that we can recommend the right solutions.

A. Free Energy Consult

If you’re curious about how a project with Evergreen could help your home, you can schedule a FREE one-hour consultation. We’ll ask you to describe:

  • Your home's current conditions

  • Your goals

  • Your priorities

From there, we’ll perform a preliminary infrared inspection throughout your home, looking for air leaks and insulation gaps to indicate which efficiency upgrades will provide the best lasting value.

B. Project Design with Energy Audit

Once you’ve decided to move forward with home improvements, we’ll gather more detailed data about your home to design a customized efficiency project with a concrete price and estimated energy savings.

Retrofit your home completely, or phase in improvements over several years—whatever works best for your family and budget.

Step 2: Completing Home Performance Services

Once we know what’s causing the problems in your home, we’ll implement lasting solutions. We offer comprehensive services to make your home more comfortable and energy efficient. Learn more about how these services can benefit your MidCoast home:

Basement Encapsulation

Even a small amount of moisture in your basement can leave the rest of your home battling mold growth, poor indoor air quality, and inconsistent temperatures. Adding basement encapsulation can improve your Bar Harbor home’s efficiency and overall health.

Many homeowners are surprised to learn that insulation can benefit your home year-round, but it’s true! Insulation is your home's best protection against exterior temperatures interfering with your home comfort and driving up your energy costs.

Protect your wallet from high HVAC costs by adding insulation!

Air Sealing

Air sealing is a lesser-known service that can make an enormous difference in the efficiency, comfort and indoor air quality of your home.

During construction or renovations, it’s common for builders to leave small gaps and holes in your home’s outer “shell”, impacting your home’s efficiency and even allowing pests easy access to your living areas. By adding air sealing, you can prevent air leakage and pest infestation, making your home healthier and more energy efficient.

Replacement Windows & Doors

Windows and doors are more than just cosmetic components of your home. With the wrong products or improper installation, they can become major points of inefficiency in your Portland home. 

Evergreen Home Performance is proud to offer quality windows and doors to help you maintain the quality of your home’s barrier against the outdoors.

Step 3: Measuring Your Results

The final step in our process demonstrates the value of your investment by measuring the results. 


 We don't just install a product and leave. Our post- production energy analysis measures the impact of your efficiency upgrades and verifies that our work meets safety and quality standards.


We love hearing from our customers! We check in after your project and encourage you to keep us posted on your results.

Our team has the training and experience to solve your home's unique challenges, and the courtesy to make your home improvement contracting experience top-notch.
