Hidden insulation problems in a newer Belfast home

How a Belfast homeowner uncovered attic insulation issues and saved $4,000 with Efficiency Maine rebates

The problem: A “newer” home that wasn’t performing the way it should

After years living in older homes with obvious insulation problems, Tom M. expected his 2008 Belfast home to be comfortable and efficient. Instead, he quickly discovered a major issue: the attached garage had no insulation – just bare studs.

Concerned about winter comfort and energy loss, Tom contacted Evergreen Home Performance for a Belfast insulation estimate. What began as a simple garage project soon revealed much larger hidden problems affecting the entire home.

A broader look: When an energy advisor sees the bigger picture

Tom originally reached out about insulating the garage, but Evergreen Energy Advisor Irene suggested stepping back and evaluating the entire home first.

Her comprehensive Belfast home energy audit examined the attic, basement, and building envelope, uncovering hidden insulation and air-sealing issues that were quietly affecting comfort and energy performance throughout the house.

Without that broader assessment, Tom would have fixed only the most visible problem while larger efficiency issues remained unresolved.

What the Belfast home energy audit uncovered

The audit revealed multiple performance issues that the family had never noticed, including inadequate attic insulation, significant air leakage, and evidence of rodent entry points.

Because the home had changed ownership several times during and after the 2009 housing downturn, insulation details had been installed inconsistently, leaving gaps that reduced comfort and increased heating costs.

These hidden issues are common even in newer homes, which is why Evergreen’s whole-home evaluation approach often identifies opportunities that homeowners don’t realize exist.

The solution: Professional Belfast attic insulation and air sealing

Phase I: Main house attic (August 2024)

Evergreen’s insulation team began by improving the attic’s thermal and air barrier systems:

  • Removal of outdated insulation materials where necessary
  • Air sealing around wiring, plumbing, and vent penetrations
  • Framing improvements to achieve proper insulation depth
  • Dense-pack cellulose installed in attic slopes (R-44)
  • Loose-fill cellulose installed across the ceiling plane (R-58)
  • Air-sealed attic hatch and improved attic access

After installation, blower-door testing showed a 15% reduction in air leakage, improving comfort and reducing energy loss.

Phase II: Garage insulation (September 2025)

About a year later, Evergreen returned to insulate the attached garage – the original concern that led Tom to call. Insulating the garage walls and roof slopes helped reduce cold-air transfer into adjacent living spaces, completing the home’s building-envelope improvements.

Making sense of Efficiency Maine rebates

Navigating available incentives was a key part of the project. Evergreen helped Tom identify qualifying upgrades and complete the rebate process, resulting in $4,000 in Efficiency Maine incentives for the attic improvements.

An educational experience, not a sales pitch

Throughout the project, Tom appreciated Evergreen’s advisory approach. Instead of feeling pressured to make quick decisions, he was given time to review recommendations, understand testing results, and plan improvements that made sense for his home and budget.

“I never got the sense she was really selling anything,” Tom said. “She was great, like giving advice.”

The results: A more comfortable Belfast home

Today, Tom and his family live in a home that feels noticeably more comfortable year-round:

  • Improved attic insulation levels and air sealing
  • Reduced drafts and cold spots
  • Sealed rodent entry points
  • Lower heating energy loss
  • Insulated garage reducing cold transfer into the home

Just as important, the family now has confidence that hidden building-performance problems were identified and solved before becoming costly repairs.

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 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.

Joel Wentz

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.

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.

Several years ago Brian Robinson evaluated the crawl space at my summer home on Islesboro where I knew moisture was becoming a problem. I had done quite a bit of work in the space many years prior with mixed results. When Brian offered some suggestions, they were ideas that incorporated work previously done, and would be a relatively low cost effort to improve the situation. He offered this advice over several phone conversations of some length, informally, and at no charge.

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

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.

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.

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

I used to spend winters in the bathtub because my house was so cold. This was my first winter roaming around my whole house comfortably. This even led me to decorate a little. My heating oil usage has been reduced by over a quarter: I rarely have to boost the thermostat because the temp stays at a constant. The Efficiency Maine rebates, together with the energy savings, make it affordable for me to pay for the loan I took out to finance the project. I do not worry about my pipes freezing.

They were highly recommended. I found them to be very knowledgeable and so helpful, with practical ideas. Despite my not living within their service area, they were generous with their knowledge, describing the usual solutions to correct leaks in my basement, and what the result is likely to be by following path A, B or C, and why. I was discouraged. Talking with Evergreen helped me see that my basement problems are far from insurmountable and really, fairly common in 100-year old homes. There are proven solutions.

Thanks Evergreen Home Performance for helping to make our home more efficient. Many thanks as well to Bryan for the initial walk through and recommendations to make our home more efficient and to Dave, Roland, and Jacob for a job that was done professionally and courteous.  We were amazed at the level of efficiency and everyday they made sure to protect our floors, carpets, and furniture. We had daily discussions with Dave about progress and what was being done and where they were at in the project.

Carol Fink

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!

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.
