Prioritizing Projects for a 19th Century Deering Center Home

Matt and Christa knew that the home they had just purchased in the neighborhood they loved — for the price they could afford — was going to need a lot of work. Their new home was a three-bedroom, one-and-a-half bath, 2,200-square-foot single family structure, built circa 1895 and last updated in the mid-1960s. It still had original plumbing, knob and tube wiring, lath and plaster walls, and a mix of hardwood and pumpkin pine flooring. The original wood stove heating system had been converted to an oil boiler with single pipe steam radiators. The house had no insulation to speak of — unless you count the many layers of wallpaper covering the walls.

Making a 2005 Palermo, ME Home Comfortable with Insulation & Air Sealing

After purchasing a home in Palermo, ME, the homeowner, Denise, quickly realized there were some serious issues. During the winter, the boiler was running for over 20 hours a day, and the master bedroom was still cold, despite having a dedicated baseboard radiator and thermostat (the previous homeowners used the boiler, an LP Fireplace insert, and two wood stoves to stay warm). The final straw was when an upstairs baseboard radiator froze and then burst, sending water flooding into the main floor and basement.

A Profound Difference Worth Every Penny

When Nancy fell in love with this 24-year-young gambrel-style house, she threw herself into personalizing it with cosmetic upgrades that made it hers. But worrying about heating bills and uneven temperatures kept her from fully enjoying her home. “When my pipes froze, I knew I needed to do something,” says Nancy. “I’d seen the Evergreen signs around, so I knew exactly who to call.”

Eliminating Basement Moisture – and Anxiety

Wyatt and Emily hadn’t lived in their 1930s bungalow very long before they called Evergreen. From “crazy ice dams” to basement moisture, they had a list of concerns that weren’t going away – or allowing them to fully enjoy their home. “It didn’t seem like the house was about to fall down, but it didn’t seem sustainable either,” says Wyatt.

Planning for Sustainable Comfort

When Hans & Jen bought this beautiful gambrel in the heart of Brooks, they aimed to turn the “beautiful – but drafty as all get-out” house into a cozy, dry home. They scheduled an energy audit and got right to work on efficiency upgrades, and like many homeowners, they’re working in phases.

Being Environmentally Responsible – and Financially Savvy

When Matt & Patsy bought their first house, they knew the 1890 New Englander needed work. “The bones were solid, but there were a lot of issues,” Matt reports, including a wet basement, drafty rooms, and high energy usage that worried their budget and their consciences.

Investing in Comfort – and Savings

Jen grew up spending summers down the road from this Cushing, Maine cottage, so she snapped it up when it went on the market in 1985. But transforming it into a cozy home took years. She moved walls, reconfigured rooms, and renovated the living space, but didn’t know where to start on energy efficiency. “I was afraid that if I did something myself, I’d do the wrong thing and make it worse.”

Aging in Place, Warm & Cozy

Vera and her husband built this log cabin in Cushing, Maine 30 years ago and had always heated with wood they cut on their own land. But when her husband passed away, Vera couldn’t keep up with the chopping and hauling. She began relying on the oil furnace – and noticing all the drafts. “It’s been such a cold home, and I knew I couldn’t keep living there if I couldn’t get it warm,” says Vera.

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 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.

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!

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!

We are so pleased with the work the team from Evergreen Home Performance did in our home. The project included encapsulation of our basement with a reinforced vapor barrier, installation of a sump pump, spray foam insulation on the walls and insulation of the heating duct work. Everyone at Evergreen was friendly and professional. The project was completed on time and in budget. Our home is much cozier and warmer since the project was completed.

I had gotten estimates from several other companies, but Evergreen was in another league entirely with their professionalism. If you want the job done correctly, I couldn't recommend this company enough.

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.

I made the mistake of NOT hiring this company last year when I bought and renovated my home. I have brought them in now and what a difference. This group knows what they are doing. They take a complete look at everything and believe they can make your home more energy efficient. They are very professional in the way they approach problems and solutions. And they find ways to save me money. Don't bother with anyone else. Bring Evergreen in before you do anything. Let them assess your issues and give you the right solutions.

I highly recommend Evergreen! 1st, I had a home efficiency inspection (that was free) & Bryan P. was great! He took the time needed, asked & listened to what I thought were priorities, explained clearly what he thought were priorities & why, then gave me numerous options. No pressure whatsoever. Then I had my attic sealed & insulated as the 1st step & Bryan came along on day 1 to introduce everyone & make sure we were all on the same page. Bruce's team (inc. Kelsey & Roland) did the work - they were exceptional!!

The Evergreen crew who installed insulation in my attic were fantastic! They were very professional, worked exceedingly hard, and they did an excellent job. They were very pleasant and friendly to be around. They cleaned up beautifully after each work day, and left my home in great shape on when they walked out the door for the last time. I can't believe they were able to accomplish all that they did with heat soaring into the 80s and 90s. It was pretty unbearable up there! They have my highest praise and my gratitude.

I was extremely pleased with the professionalism and quality of service that I received from the Evergreen team. I met Richard to discuss options for insulation. I knew immediately that I wanted to do business with them because he did not try to over-sell extra services that I did not need. Dave was the project manager. He was not only kind, but very respectful of my home. I would highly recommend this company.

I never leave reviews, but had a great experience with Evergreen and wanted to spread the word! In short, we worked with them to insulate our roof this winter and have noticed surprising immediate results. The constant ice dams I have wrestled with are completely gone, and the home is noticeably more comfortable. It's a little too early to tell if our oil bill is going to reduce, but I imagine we will see an impact there as well.

Bryan, Dave and the entire Evergreen team are wonderfully professional, prompt and thorough. I enjoyed working with them and look forward to continued work as we upgrade our home! Thank you so much for your professionalism, fairness, time and diligence.

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

The team members were very professional, worked very hard, paid very close attention to detail and cleaned up meticulously every day. I really appreciated the care they took knowing the smallest details were going to make a big difference to our heating bills. Thank you!
