Helping Renovations Work Efficiently Together

The House
Marianne & Steve’s Cape Elizabeth home was “a bit of a mishmash” – a 1939 log cabin with additions completed in 1998 and 2011. The result was beautiful but drafty – and expensive to heat. “Our bedroom door would rattle when the wind blew,” reports Steve, and the upstairs office was “either stifling hot in the summer or freezing in the winter.”

There was no crisis, but they agreed that it was time to take action. “We called Evergreen because we wanted to be more comfortable and to use less oil.”

The Consult
Evergreen identified opportunities to make the multiple additions on Marianne & Steve’s work better together, and to make the whole house more livable year-round. “We asked questions, our Energy Advisor asked questions,” said Steve. “He saw some things we expected and some things that surprised us, and he was right on the money.”

The Audit
Blower-door testing revealed that Marianne & Steve’s home was twice as leaky as required by natural ventilation standards. This uncontrolled exchange of interior and exterior air meant that they had to heat the house from scratch every 80 minutes, driving up fuel costs and keeping the house uncomfortably cold. Infrared analysis traced much of the air leakage to the un-insulated basement foundation and the attics, especially in the side attic that wraps around the upstairs office.

The Project
Evergreen engineered a complete solution for Marianne & Steve’s energy efficiency challenges and recommended air sealing and insulating the attics, insulating the basement foundation, and installing a custom-built insulated bulkhead door. Evergreen’s trained, certified production team made the improvements.

Energy Efficiency Case Study | Evergreen Home Performance | Cape Elizabeth Maine “The project was a piece of cake,” says Steve. “We’ve lived through two home renovations in two different places, and Evergreen’s team was the neatest, most professional crew we’ve ever worked with. We were very impressed.”

The Results
Marianne & Steve’s Evergreen project reduced their home’s air leakage by 36% and transformed the house. “We set the temperature last winter and didn’t think about it again,” said Steve. “And we spent less than we ever had before,” added Marianne.

Wintertime comfort isn’t the only gain, though: the house is cooler in the summer and temperatures are more consistent year-round. “If you take the long view on heating, cooling, and overall comfort over time, energy efficiency is a no brainer.”

Evergreen came out 2 years ago to do an assessment and insulate our roof. This year we had them come back and do the basement as well. They are hands-down the best crew we've ever hired to work on our house. They are experts at what they do, and super meticulous in their work. After working in our house for a week with blown insulation, there was no trace they were ever here. We've seen a huge decrease in our energy bills while at the same time the house has become way more comfortable. Can't recommend them enough.

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.

"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.

Highly recommended. Our heating usage is now less than half what it was before we had our roof insulated. Evergreen was knowledgeable, friendly, and left no trace they were ever in our house. Not only is our heating bill much lower now, but our home is generally more comfortable year-round with less temperature fluctuations. Money well spent.

RC Lations

Great company. Very professional and thorough. They take the time to explain everything and offer options to fit your budget. Wonderful experience from start to finish.

I used to spend winters in the bathtub because my house was so cold. This was my first winter roaming around my whole house comfortably. This even led me to decorate a little. My heating oil usage has been reduced by over a quarter: I rarely have to boost the thermostat because the temp stays at a constant. The Efficiency Maine rebates, together with the energy savings, make it affordable for me to pay for the loan I took out to finance the project. I do not worry about my pipes freezing.

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.

We had a fantastic experience working with Evergreen to insulate our roof this winter. Everyone was extremely friendly throughout the process - the crew at our home worked hard, were approachable with questions, and the team leader even showed me around the project to point out specific areas they were working to improve.

Joel Wentz

My experience with Evergreen was excellent. From their thorough and thoughtful initial consultation to their detailed post-work visit, the team was professional, knowledgeable, and responsive. Their workmanship was top notch. Our home is now much warmer and more efficient. I highly recommend their services!

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.

We had Evergreen Home Performance of Rockland come in to make our home more energy efficient, and what a TOP notch crew. Brian and his crew did an amazing job from start to finish. Very knowledgeable and professional. We would Definitely highly recommend this crew to anyone who is looking for energy efficiency in their home with a company that truly is an expert and knows how to do a quality job and truly cares about their customer.

We had Evergreen come out to our tiny old (100+ year old) house to see what they would recommend for decreasing our carbon footprint, saving money, and increasing our comfort in the cold season. Richard and Bryan were great to work with, patiently answering our many questions and walking us through multiple options. We could only afford to tackle a few areas this year; we ended up replacing some windows and having them weatherize the entire house.

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 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!

Evergreen did a fantastic job replacing 28 windows in our house. They were friendly, courteous, and very detail oriented. Brian did a great job planning, estimating and executing the project. Our energy use has dropped significantly since the work was done.
