Making Home Quiet, Comfortable, and Enjoyable

Tom & Jennifer never meant to live here. They bought the 1850s cape as a landing pad while they figured out where they really wanted to be. They didn’t paint the walls, and they didn’t worry about the drafts that kept the house cold and uncomfortable no matter how much oil and wood they burned. But after nearly a decade, “we came to the realization that the best thing for us was to try to make this house work.”

Helping Renovations Work Efficiently Together

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.”

Insulating a Summer Cottage for Year-Round Comfort

This lakeside cottage was the first of three identical summer camps built in Camden in 1909. It took 2.5 cords of wood and almost 800 gallons of propane to make the mostly uninsulated home livable year-round.

Creating Even Temperatures – and a Toasty Toilet Seat

As Lee showed Evergreen’s President, Richard Burbank, around the house she’s lived in for twelve years, she realized how much energy efficiency has shaped the way she uses her home. “The consult revealed issues I hadn’t anticipated… I thought Evergreen would come in and tell me things, but they asked questions other people wouldn’t have known to ask, and they really listened to my experiences. I got to express my preconceptions, and my misconceptions, and to make sense of my home.”

Managing Costs with Energy Efficiency

Beth and Jon knew their energy bills would go up when they moved to a larger house, but “the amount of oil we used in a mild winter was really concerning.” To learn where their money was going, they scheduled a free one-hour consult with an Evergreen Energy Advisor.

One Old House, Two Efficiency Maine Loans, and Three Local Companies

This 1830s farmhouse in Rockport, Maine came with period charm and an overwhelming fuel bill: 750 gallons of oil, plus 6 cords of wood, plus all the electricity it took to power an inefficient old water heater. Even worse, all that didn’t even keep the house warm.

Making the Educated Choice

This lovingly maintained 1840s home in Belfast, Maine was cold – even when the homeowners spent a fortune trying to heat it – and complicated – especially in the cellar, where many of the comfort and efficiency problems originated.

Combatting the Elements for Comfort & Savings

John had been living with a cold house and high energy bills for so long that it felt normal, but when he heard about Efficiency Maine’s rebate program, he decided to call. “In Maine, anything we can do to combat the elements is worthwhile,” says John, “so I figured it would be worth looking into.”

Cutting Costs and Improving Health

This Greek Revival home in Belfast, Maine was built in 1842. Even with the thermostat set at a moderate level, it took 1500 gallons of oil, 150 gallons of propane, and “a whole lot of money” to heat the place. There were shallow puddles in the basement whenever it rained hard, which of course encouraged black mold.

Financing Comfort and Efficiency

This 1900 Gable-front home in sits on an acre of land in the middle of Camden, Maine. Burning 3 cords of wood and 550 gallons of propane kept the 1430 sq ft mostly warm, though some rooms were freezing while others boiled. Plus, “a furnace that ran all the time to heat the water” wasted much of that energy.

Treating a Tricky Gambrel Roof

When Diane and her father built this house in the 1970s, they used state-of-the-art materials for that time and built with efficiency in mind. But over time, things that had been tight weren’t so tight anymore. It took four cords of wood to keep the house warm, and they often had to stoke the fire in the middle of the night.

Turning a Full-time Project into a Cozy Home

The basement of this 1835 Rockland, Maine home was something else. There was the 70 year-old woodstove – “it heated the cellar really well, and eventually some of that heat filtered upstairs” – and the coal boiler fueling a DIY radiant heat system. There was also water – almost a foot of it several times a year, soaking the five cords of wood that had to be lugged inside in the fall. The furnace had to be stoked six times a day.

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)

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.

Our house still the most efficient home we’ve ever lived in. And we have you folks to thank for that! A special howdy to Brian Robinson please!

Bruce O’Donal and Eva Butler

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.

The Evergreen Team did a fabulous job and was very tuned and responsive to the particular needs we had. The job was done right on budget and we are thrilled with the improved warmth and energy efficiency.

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.

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.

I cannot say enough great things about working with Evergreen Home Performance. Everything including the initial consultation, the fabulous work crew, the office support and the final resolution was handled in a caring and professional manner. My only regret is that I did not know about them earlier. I enthusiastically recommend Evergreen to anyone with concerns about home energy use.

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.

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.

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.

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 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.

Evergreen did an amazing job insulating our historic home. Their professional staff worked hard to ensure the tough areas in the attic were covered, and clearly communicated their progress. We are seeing the results with our discounted heating bills. Thank you, Evergreen!
