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!

Awesome company. It was a few years ago that they did the audit and then we commissioned them to do the work. We subsequently sold our house and moved to South Africa, but their level of service and expertise will live on.

Update 12/2018: Evergreen has completed Phase II of my house (insulating and installing air/moisture barrier on exterior walls, replacing old windows) and now that heating season is upon us, the difference is astonishing. The house is tight as a drum and so easy to keep warm. Worth every penny. Thank you all! Working with Evergreen was a positive experience from start (no charge energy audit) to finish (a MUCH more comfortable home). Brian Robinson spent a lot of time with me on the audit, explaining clearly what he was finding in my ca.

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.

Very Satisfied with the work performed by Evergreen. Professional employees, high quality work done in a timely manner. My sales rep was Justin, and he was phenomenal During the initial walk around my house, he gave me great ideas for how to improve the efficiency of our home. We will consult with Evergreen for our future home projects.

Evergreen did everything they said they would and more. I actually don't mind going into the basement now since they sealed it. The air quality in the house is noticeably better and it's warmer in the winter. We can even store clothing down there where before, whatever was in there would mildew. Even the spider population declined! I used to vacuum so many of them from the corners of the ceilings in the house. Not any more!

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.

Professional, friendly and hard-working staff. The product/approach they use for insulation is top notch. We felt the difference immediately, both from added warmth and eliminating drafts. The team and management were easily available to answer our questions or coordinate meeting times. Highly recommended.

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 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.

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

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

I was extremely pleased with the professionalism and quality of service that I received from the Evergreen team. I met Richard to discuss options for insulation. I knew immediately that I wanted to do business with them because he did not try to over-sell extra services that I did not need. Dave was the project manager. He was not only kind, but very respectful of my home. I would highly recommend this company.

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.

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.
