The Home Performance Upgrade You Will Notice Most? Basement Insulation.

Back to Blog

As a home performance contractor, we talk to many homeowners throughout Southern Maine and the Midcoast who want to know which home performance upgrades will make the biggest difference. With each home presenting its own challenges, and with so many upgrades to choose from, it can feel overwhelming to comb through the retrofits that will increase your home comfort and energy efficiency the most. But we hear it time and time again: Insulation for the basement and basement encapsulation makes the biggest difference for Maine homes! Here’s why.

Why Basement Insulation Works for Maine Homes

By trusting a local basement insulation contractor to insulate the area under your house, you are turning your basement into a conditioned space. The role of insulation is to prevent the transfer of heat between your home’s exterior surfaces —  like the foundation — and the outdoors. Once air sealed and insulated, your basement will no longer be at the whim of Maine’s sub-freezing winter temperatures and stuffy, humid summers. The more stable the temperatures are in the basement, the more stable the temperatures will be throughout your home! Some of the benefits of basement insulation include:

  • No more cold floors in the winter
  • Greater indoor temperature stability
  • Reduced “stack effect”
  • Lower heating & cooling costs
  • Fewer indoor drafts

The Best Way To Insulate a Basement

Some insulation contractors may tell you that insulating the basement ceiling is all you’ll need to do to insulate your basement — false! Insulating the ceiling may keep your floors less cold, but it will not do much for the actual temperature of your home, and could lead to frozen water pipes and cold heating system distribution networks (air ducts or hot water piping). We find that the best way is to insulate the basement walls. Why, you ask? Your basement walls are where your home is most vulnerable to the unpredictable New England weather, including moisture intrusion, cold air drafts, and the conduction of cold temperatures through your foundation’s stone, brick, or concrete wall surfaces.

By insulating the walls of your basement, you are preventing those unwanted temperatures from entering your living space in the first place, instead of just preventing them from reaching the floors of your home.

Spray Foam vs Rigid Foam Insulation? It Depends.

The second aspect of properly insulating a basement is sealing up any air leaks. For older homes with stone or brick foundations,  utilizing an expanding spray foam insulation product, air seals and insulates all at once. And for newer homes with uniform concrete basement walls,  taped and sealed rigid foam panels can be a great solution. These treatments are particularly beneficial for Midcoast Maine homes that experience basement air moisture throughout all four seasons. The less moisture in your home, the lower your risk of mold growth.

Wondering why your floors have been so cold this winter?

The answer is in your basement. 207-594-2244

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

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

The team members were very professional, worked very hard, paid very close attention to detail and cleaned up meticulously every day. I really appreciated the care they took knowing the smallest details were going to make a big difference to our heating bills. Thank you!

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.

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.

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.

We had Evergreen redo the insulation in our roof. The team handling our project did a great job. They left the house spotless. We've already noticed the difference in how much better our house is retaining heat. I would definitely recommend and will use them for future 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!

Loriel Van Dusen

The Evergreen Team did a fabulous job and was very tuned and responsive to the particular needs we had. The job was done right on budget and we are thrilled with the improved warmth and energy efficiency.

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 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!

Great job installing windows and insulation.

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.

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.

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.
