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.

Melting the Dog’s Dish – and More

Bowers Mansion is a 3500 square foot historic home in Saco, Maine. Built in 1885, the balloon-framed home had long, uninsulated chases behind every wall. Even with a third of the house closed off and the thermostats low, heating to a livable temperature took a whopping 1800 gallons of oil.

Managing Moisture Problems for Good

1890’s Victorian in Rockland

This stately 1895 Victorian has been lovingly restored by its present owners with breathtaking historical sensitivity. Just as sensitive to environmental impacts, they installed a wood pellet boiler in the effort to reduce fossil fuel use. Having an energy audit and installing the recommended improvements was just the next step. All told, the energy upgrade helped reduce this home’s air leakage by 43%, dramatically reducing energy costs and creating a more efficient, more comfortable home.

Early 1800’s Cape

This 1800’s cape qualified for the first 50% energy reduction incentive of $3,000 from the Efficiency Maine Home Energy Savings Program. The home is beautifully renovated on the interior but the wet, drafty basement, lack of wall insulation, and leaky attic all caused the home to be very hard to keep heated. Despite burning 7 cords of wood and 350 gallons of oil every winter, the owners still had to wear coats and hats inside to stay comfortable.

1980’s Raised Ranch

In the last week of December 2009, this 1980’s raised ranch was the first home to qualify for an Efficiency Maine’s Home Energy Savings Program incentive of $1500 for completing an energy efficiency project estimated to save at least 25%. The home is heated with propane using a direct vent wall furnace which consumed 850 gallons the prior year.

From start to finish, our experience was incredible. Justin was extremely helpful. The crew was fast, friendly, and efficient. And most importantly, our home is WAY warmer and our heating is less costly. I'd highly recommend evergreen to anyone looking to upgrade their home!

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.

I would recommend Evergreen wholeheartedly because of their professionalism, their follow through, and thoughtful project planning.

Evergreen has insulated two homes that we've owned now and both times we experienced exceptional service and craftsmanship. Our rep, Justin, went above and beyond answering questions and the installation team was attentive to every detail, including pulling out old poorly installed insulation and redoing a bathroom fan that wasn't up to current code. They also left the place spotless every day! Our home is already so much warmer this fall and we are looking forward to using less oil this winter.

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.

The crew members from Evergreen Home Performance each made sure to greet us every day, while maintaining their distance in this time of the pandemic. Their work took a total of nine days, spread over three weeks. Even though they were working in multiple rooms of our house, as well as the basement and attic, they were unobtrusive and always cleaned up after themselves every day. The on-sight manager kept us informed of their daily schedule so we'd know which parts of the house they'd be working on.

Last week, my oil company asked if we were using some other kind of fuel because our usage was so much less than they had expected We are very happy with the results; the house is much more comfortable

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!

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

A thorough inspection of our (older) house and its energy needs. Competent and personable work crew.

Jacob Watson

Evergreen was so helpful in securing us Efficiency Maine funding for a big attic insulation project early this winter. They did all of the paperwork, and totally guided us through a vermiculite removal process that included a payment from a trust for the procedure. I could instantly feel the second floor being so much warmer than before. The boiler does not kick on nearly as frequently since they completed the job. It was worth every penny! Brian Robinson was so thorough throughout the whole process including a full walk through after the job had been completed.

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!!

Really great experience from start to finish with Evergreen. They helped us prioritize what needed to be completed first, and has made a significant difference in our hearing costs already. Plus they were really friendly and considerate to work with!

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.
