Home Heat Loss

Home Heat Loss infographic

Keeping your home warm during the winter is important here in the Portland area and MidCoast Maine. However, poorly insulated homes allow precious heat to escape, leading to hefty energy bills and unnecessary wear & tear on your HVAC system. In fact, homes with insufficient insulation can cause heat loss of up to 30%!

Where Home Heat Loss Occurs

Let’s take a look at common areas of heat loss in a home and how air sealing and insulation upgrades can help you get your comfort back.

Basements & Crawl Spaces

These areas are often left exposed to the elements, allowing both unwanted airflow and moisture to infiltrate a home’s living spaces. Basement encapsulation creates an added layer of protection.

Ceilings, Walls, & Floors

Poor insulation and air leaks in your home are leading contributors to heat loss. These leaks are often unseen but can amount to heat loss that’s like leaving a window open in your home all year long.

Attics

When an attic isn’t equipped with proper insulation, it can make your home prone to ice dams as heat rises. Attic insulation helps to combat heat loss by keeping it in your home, where it belongs.

Fireplaces

Does your fireplace have an open, missing, or broken damper? If so, it won’t keep your home comfortable, but actually contribute to heat loss.

Plumbing

If plumbing pipes and pipe connections are left uninsulated, the gaps they leave in your walls and foundation will allow unwanted airflow to increase your energy bills, but insulation can help.

Ducts & Vents

Unsealed ducts and poorly installed vents can create air leaks that cause significant heat loss of up to 40% of your HVAC’s output!

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.

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.

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.

From beginning to end – that is from the moment Justin McEdward stepped into our home to assess our energy conservation needs until the crew left – the Evergreen Home Performance process went absolutely smoothly. Justin made a thorough inspection and took pictures with an infrared camera. His proposal described the scope of work in detail, and he explained what we could expect the proposed work to accomplish. Our proposal was forthcoming within a couple of days, and Justin was available to discuss it and answer questions.

Adrienne Harkavy

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

We are so pleased with the work the team from Evergreen Home Performance did in our home. The project included encapsulation of our basement with a reinforced vapor barrier, installation of a sump pump, spray foam insulation on the walls and insulation of the heating duct work. Everyone at Evergreen was friendly and professional. The project was completed on time and in budget. Our home is much cozier and warmer since the project was completed.

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

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.

The folks at Evergreen did a great job fixing a rather major insulation problem in my house, which they helped identify with a great audit. When the work began, they were thorough, upbeat, and -- dare I say it -- efficient. I strongly recommend them.

Michael Williams

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.

Very easy process, start to finish. Friendly, professional, and really know their stuff. They made some improvements to our condo and we were very happy with how it played out. Would definitely recommend them.

Clayton Eames

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.

We are thrilled with the job Evergreen did to transform our 213 year old home into a warm, draft-free, cozy space. The entire team led by Bruce was prompt, courteous, knowledgeable, and hard working. If Evergreen could transform our home in this way, we are sure they would make a comparable difference in YOUR home!

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

Jacob Watson

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…
