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.”

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.

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.

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.

Evergreen did a fantastic job insulating our 1930's home. The onsite team was professional, clean, and really just a joy to interact with throughout the process. A blower test at the end showed a significant decrease in air leakage. I highly recommend Evergreen.

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.

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!

We had Evergreen energy do blow-in cellulose. I was very happy with the result. They tested with blower-door before and after. House is now MUCH warmer. Also, in the time since when I've had to open walls for various access, I've been impressed with how they got the insulation packed in everywhere. I'd use them again.

We just finished a large project of air sealing and reinsulating our 1890s basement and attic which 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.

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.

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!!

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.

"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.

Evergreen is the "go-to" company for improving the efficiency of your home. There are others to choose from but none so effective, honest, and capable as Evergreen. They did a great quantity of dense packing cellulose to improve our home (both for energy efficiency and for sound insulation) and it was totally successful. They are on-time, helpful, and caring. They clean up to a level that can't be over emphasized. This was the second time we employed them and we'd use them again if the opportunity came. You'll not be sorry to select Evergreen.

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.

In the final stages of selling our home, and with a closing date set, an inspection came across an unanticipated issue in our attic. We quickly called in contractors, but nobody was able to identify the source of the problem. Then we thought of Evergreen. Brian Robinson was on site the next morning and immediately identified the source (a faulty roofing job completed three years earlier which had effectively sealed up portions of the ridge vent and restricted air flow - not easily visible with a quick inspection).
