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

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!

I cant say enough about this company and the benefits that it created for our family. They are very professional and have effectively re-insulated our home. The heating bill proves the point.

From start to finish, our experience was incredible. Justin was extremely helpful. The crew was fast, friendly, and efficient. And most importantly, our home is WAY warmer and our heating is less costly. I'd highly recommend evergreen to anyone looking to upgrade their home!

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…

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.

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.

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.

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.

The Evergreen Team did a fabulous job, well exceeding our expectations, In just over a week they transformed our very drafty, noisy 213 year old house into a snug, draft-free, quiet haven with warm floors! The team was prompt, did everything they said they'd do and more. We are thrilled!

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.

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!

I highly recommend Evergreen! 1st, I had a home efficiency inspection (that was free) & Bryan P. was great! He took the time needed, asked & listened to what I thought were priorities, explained clearly what he thought were priorities & why, then gave me numerous options. No pressure whatsoever. Then I had my attic sealed & insulated as the 1st step & Bryan came along on day 1 to introduce everyone & make sure we were all on the same page. Bruce's team (inc. Kelsey & Roland) did the work - they were exceptional!!

Melissa M.

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.

Thorough, smart, informative, integrated, and communicative -- that's how my experience was with Evergreen even with the covid interruption midstream. The team picked up where they left off, insulated basement and air sealed attic and knee wall in 100' temps under the eaves! This business group was a pleasure to work with.
