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

We initially contacted Evergreen through Efficiency Maine for an energy audit, which was conducted promptly and professionally by Justin McEdward, one of their Energy Advisors who is BPI-certified. After a thorough inspection of our newly purchased home, Justin explained in great detail what we needed and did not need. It was agreed that Evergreen would remove all of the existing attic insulation, which was not adequate, and replace it with blown in cellulose, to a rating of R-60.

Great job installing windows and insulation.

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.

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…

This team of individuals was professional at all times. They set up barriers that kept the dust at a minimum. They conducted an air flow audit and cut the draft circulation from the outside in half by sealing cracks. They hauled out the old insulation and replaced it with blown in insulation with an R - 60 Value. They also did the rebate paperwork so that I could get my $1500.00 rebate from the state of Maine. I highly recommend Evergreen Home Performance!

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.

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 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.

Evergreen came out 2 years ago to do an assessment and insulate our roof. This year we had them come back and do the basement as well. They are hands-down the best crew we've ever hired to work on our house. They are experts at what they do, and super meticulous in their work. After working in our house for a week with blown insulation, there was no trace they were ever here. We've seen a huge decrease in our energy bills while at the same time the house has become way more comfortable. Can't recommend them enough.

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 did a fantastic job insulating our 1930's home. The onsite team was professional, clean, and really just a joy to interact with throughout the process. A blower test at the end showed a significant decrease in air leakage. I highly recommend Evergreen.

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.

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

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 of air sealing and reinsulating our 1890s basement and attic which 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.
