Basement Insulation or Encapsulation: Which do you need?

Back to Blog

Most Maine homeowners don’t spend much time in their basements—using them mostly for storage, and maybe laundry if space is tight upstairs. As a result, it can be easy to miss the signs that your basement is contributing to poor home performance, unhealthy air, and high energy costs.

Evergreen Home Performance is here to help Mainers in Rockland, Belfast, and Bath improve their home health, comfort, and efficiency with basement services. But which service will best suit the needs of your home? Learn more about what signs could indicate that you’d be best served by basement insulation, or exploring basement encapsulation.

Top Signs Your Basement Needs Attention

Between the moisture in seacoast air and Maine’s temperature fluctuations throughout the year, our basements need to put up with a lot. Often, these spaces are under-cared for because homeowners underestimate a basement’s impact on whole-home comfort and health.

Common signs of home performance problems caused by your basement can include:

  • Mold growth in your basement

  • High humidity

  • Musty smell in your basement and even on the first floor

  • High heating and cooling costs

  • Uneven temperatures in your home

How to Know if You Need Basement Encapsulation or Insulation?

Encapsulation

An un-encapsulated basement is a common cause of allergy symptoms in a home, and can lead to more comfort issues than homeowners often realize. 

Signs that your basement would benefit from encapsulation include:

  • High moisture at home, leading to mold growth

  • Presence of pests & rodents

  • A drafty basement

Evergreen wants to be sure that our services create a comfortable, healthy environment for you and your loved ones. Our 4-step basement encapsulation process includes solutions for draining excess moisture, installing a vapor barrier, improving the durability of your basement, and helping you prepare to eliminate radon,, a common problem in Maine basements and homes, . 

Insulation

Adding wall insulation and more to the basement of your MidCoast home is the best way to keep the heat you pay for from escaping. This can help regulate your heating and cooling costs year-round and reduce strain on your HVAC systems—which saves you money on system maintenance costs too. Since the rise in popularity for heat pump installation in Maine, adding insulation to your basement ceiling can also help increase your ground floor comfort.

Signs that your basement would benefit from insulation include:

  • Cold floors in the winter months

  • High energy bills

  • Inconsistent temperatures on your first floor

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

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.

Evergreen Home Performance shows its expertise from start to finish. Evergreen did three house projects in winter/spring/summer 2020 for me, attic insulation, crawl space under a porch insulation, and basement foam/vapor barrier. From my initial discussion with Bryan, I understood the reasons for choosing different types of insulation, the associated costs, and time estimates. Evergreen scheduled in advance, came when they said they would, and the crews were highly professional in their work and demeanor.

I waited a year to write this review. Evergreen finished our job late last winter. Terrific results!!! we've gone from 12-day propane deliveries to 30+ day propane deliveries. The house is noticeably warmer. The Evergreen crew was/is professional, prompt, thorough, scientific, gracious and immaculate with respect to keeping our house clean. Money well spent.

The Evergreen crew who installed insulation in my attic were fantastic! They were very professional, worked exceedingly hard, and they did an excellent job. They were very pleasant and friendly to be around. They cleaned up beautifully after each work day, and left my home in great shape on when they walked out the door for the last time. I can't believe they were able to accomplish all that they did with heat soaring into the 80s and 90s. It was pretty unbearable up there! They have my highest praise and my gratitude.

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.

Bryan, Dave and the entire Evergreen team are wonderfully professional, prompt and thorough. I enjoyed working with them and look forward to continued work as we upgrade our home! Thank you so much for your professionalism, fairness, time and diligence.

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

I am very pleased with my experience with Evergreen Home Performance. I met several times with Richard Burbank and he was very detailed in his explanations to all of my questions. He provided me with several options for improving the insulation to our home. The team of installers were very professional and respectful of our home. They did a great job of cleaning up every day after the days work and they were also very responsive to all my questions as well as we collaborated to get our home better insulated. It was a pleasure to work with Richard and…

First we have Evergreen do a BIG project worth about $20K (windows, basement, insulate & rebuild an entire wall, a door, attics, and air sealing). They were so great we had them come back later when we decided we did want to do our other door. They are professional and do great work. They take care of your home and are trustworthy, and on top of all that friendly! I highly recommend you call them!

Garreth C Debiegun

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.

Nothing but good things to say. The guys that came and did the actual work were extremely nice and did a great job. The energy audit was thorough and I was presented with multiple improvement options, I was even given ideas for improvement that Evergreen didn't offer. I never felt like I was being "sold".

Ryan Adams

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.

Kennebunk

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.
