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  • Removal of outdated insulation materials where necessary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.

Evergreen Home Performance proudly serves homeowners in Belfast, Rockland, Portland, and communities across Maine with professional insulation, air sealing, and energy-efficiency upgrades.

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.

The Evergreen team was amazing from initial assessment and planning to the crew that came to complete the work. Our basement encapsulation is the best money we've spent on our house by far. The work was thorough and high quality. And what a wonderful group of people to work with. I highly recommend Evergreen!

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.

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 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!!

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 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.

The Evergreen crew from initial inception to installation were professional, on time, and left our place spotless. The end result was exceptional.

John Brown

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.

Evergreen removed and replaced the insulation in my attic. They did a great job!, Crew was excellent, and the whole thing went smoothly, and the attic was NOT easy to get into or work in, so kudos to some hard work done well!

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).

Evergreen has just completed Phase 2 of 2 at my home. They are professional, hard-working and courteous. They communicate well..no surprises. They've gone above and beyond to make my home comfortable and were very respectful of my home.I recommend them unequivocally!!!Many thanks to Brian, Brian, Rick, Eddie, Dawson and the rest of the Evergreen crew!!

David Henry Feldman

Working with Brian and with Nate and the rest of the crew was a pleasure. They made everything very easy and understandable. This was a major renovation and they were always at the ready with a lot of information. We had an extensive renovation on the basement which was a dirt basement and it came out beautifully. We can already tell from all of the insulation work what a difference it's made in sound and temperature. Brian worked with me on the rebates that are available when you do this kind of work. I would highly recommend this company to…

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 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.
