Does My House Need Basement Encapsulation?

Many houses throughout Maine, especially older ones, suffer from various basement issues. If your home’s basement is unfinished and unencapsulated, you may be dealing with these problems regularly and not even know it.

Many houses throughout Maine, especially older ones, suffer from various basement issues. If your home’s basement is unfinished and unencapsulated, you may be dealing with these problems regularly and not even know it.

Most homeowners aren’t even aware of just how serious the issues can be if not properly addressed. Your basement has an influence over just how healthy, energy efficient and pleasant your entire home is, so if the basement in your house has problems with leaks, cracks, mold or pests, it needs to be encapsulated.

Common Basement Problems

From Bar Harbor down to Cape Elizabeth, many homes are suffering from the same concerning issues, including:

  • Leaks Causing Problems with Moisture & Mold

Basements that aren’t encapsulated tend to experience a buildup of moisture, particularly in the transition from winter to spring when leaks can easily appear due to the melting snow and influx of rain. The dark, damp environment fosters the growth of mildew and mold which can weaken the structural integrity of your home.

The moisture and mold also compromise indoor air quality. With mold spores and contaminated particulates floating around in your home’s excessively humid air, allergy and asthma symptoms are exacerbated.

  • Air Escaping & Entering

Air leaks contribute to poor indoor air quality. Radon, a colorless, odorless and radioactive gas that is the second leading cause of lung cancer, can more easily infiltrate and endanger your family.

With cracks and gaps constantly letting air in and out, your home’s energy efficiency begins to suffer. You’ll notice chronic discomfort with areas of your home that are never quite the right temperature. Your heating and cooling systems will work exceptionally hard to keep you comfortable, increasing your energy bills.

  • Breeding Grounds for Pests & Rodents

Basements with cracks and gaps are perfect homes for pests and rodents. Their presence affects indoor air quality and can even introduce other illnesses. Over time, these unwanted creatures can also make their way upstairs and infest your home.

Basement Encapsulation Process

At Evergreen Home Performance, we strive to address all the problems that can be plaguing your basement with a comprehensive encapsulation process. It will make your home healthier, more comfortable and energy efficient while also being the first step towards a finished basement, if that’s an upgrade you’re considering in the future.

1. Drainage for Bulk Water

Since moisture is one of the main issues affecting basements from the Midcoast down to Southern Maine, we begin by drawing away excess water. We build a trench and install a sump pump system to address bulk water. Our team also installs an effective water channeling system to draw water away.

2. Vapor Barrier Installation

Since water can also infiltrate through excess moisture in the air, our expert team will install an airtight, durable vapor barrier. The vapor barrier always runs under support posts and appliances, and up the foundation walls, where it’s fixed with spray foam insulation.

3. Concrete Slab

After the vapor barrier is in place, most homeowners have a new concrete slab installed. A durable, level surface will make it easier to convert the basement into living space in the future.

4. Radon Mitigation Preparation

We want your home to be safe and healthy for you and your family. That’s why our basement encapsulation process includes measures for radon mitigation preparation like helping with radon testing and making sure your project is fully compatible with a radon ventilation system.

I used to spend winters in the bathtub because my house was so cold. This was my first winter roaming around my whole house comfortably. This even led me to decorate a little. My heating oil usage has been reduced by over a quarter: I rarely have to boost the thermostat because the temp stays at a constant. The Efficiency Maine rebates, together with the energy savings, make it affordable for me to pay for the loan I took out to finance the project. I do not worry about my pipes freezing.

We absolutely loved our experience with Evergreen. The team was incredibly kind, professional and great to work with. We're very impressed with the quality of work of the Evergreen team and how easy they made everything! Our house had barely any insulation ahead of this project and the results are amazing. Insulating the attic, walls and basement with Evergreen allowed us to tear a 50-year-old furnace, ductwork and oil tank out of the basement and now heat the home with new heat pumps. Evergreen also added 100 sq ft of clean, new storage space to the attic!

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.

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.

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".

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.

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.

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

Highly recommended. Our heating usage is now less than half what it was before we had our roof insulated. Evergreen was knowledgeable, friendly, and left no trace they were ever in our house. Not only is our heating bill much lower now, but our home is generally more comfortable year-round with less temperature fluctuations. Money well spent.

Great job installing windows and insulation.

Evergreen is the "go-to" company for improving the efficiency of your home. There are others to choose from but none so effective, honest, and capable as Evergreen. They did a great quantity of dense packing cellulose to improve our home (both for energy efficiency and for sound insulation) and it was totally successful. They are on-time, helpful, and caring. They clean up to a level that can't be over emphasized. This was the second time we employed them and we'd use them again if the opportunity came. You'll not be sorry to select Evergreen.

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.

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 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

Led by Brian Robinson, the Evergreen Home Performance team just completed an insulation refit at my home. It was truly a great experience from start to finish, a period of time that was a fraction of the time that I originally anticipated due to the team's unbelievable work habits and professional knowledge of their tasks. As impressive were the communication skills and friendliness of each and every member of the team.
