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.

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.

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.

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.

Nothing but good things to say. The guys that came and did the actual work were extremely nice and did a great job. The energy audit was thorough and I was presented with multiple improvement options, I was even given ideas for improvement that Evergreen didn't offer. I never felt like I was being "sold".

Ryan Adams

I waited a year to write this review. Evergreen finished our job late last winter. Terrific results!!! we've gone from 12-day propane deliveries to 30+ day propane deliveries. The house is noticeably warmer. The Evergreen crew was/is professional, prompt, thorough, scientific, gracious and immaculate with respect to keeping our house clean. Money well spent.

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.

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.

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.

Bonnie Eustace

Evergreen listened and produced a thoughtful evaluation, proposal and comprehensive plan for our attic and basement. They exhibited excellent workmanship, teamwork, and came back as planned after the completion of the job to test the outcomes. Their overall performance as insulation and home improvement contractors is truly outstanding and we highly recommend them.

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.

Our basement was the eyesore of the house. I wanted to make improvements, but first needed to make structural, insulating and moisture mitigation improvements. Evergreen was professional and competent in taking on a complex project of not only encapsulation and insulation of basement and crawlspace, but completed needed improvements to the structural integrity of the wood floor platform above a crawlspace and brought in a concrete contractor to pour where there was once a rotting, tiered wood platform - replacing that area with a more functional and tight tiered concrete area.

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.

Karen W.

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!

I cant say enough about this company and the benefits that it created for our family. They are very professional and have effectively re-insulated our home. The heating bill proves the point.

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!!
