Does My House Need Basement Encapsulation?

Back to Blog
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.

Several years ago Brian Robinson evaluated the crawl space at my summer home on Islesboro where I knew moisture was becoming a problem. I had done quite a bit of work in the space many years prior with mixed results. When Brian offered some suggestions, they were ideas that incorporated work previously done, and would be a relatively low cost effort to improve the situation. He offered this advice over several phone conversations of some length, informally, and at no charge.

I had gotten estimates from several other companies, but Evergreen was in another league entirely with their professionalism. If you want the job done correctly, I couldn't recommend this company enough.

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!

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.

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.

Thanks Evergreen Home Performance for helping to make our home more efficient. Many thanks as well to Bryan for the initial walk through and recommendations to make our home more efficient and to Dave, Roland, and Jacob for a job that was done professionally and courteous.  We were amazed at the level of efficiency and everyday they made sure to protect our floors, carpets, and furniture. We had daily discussions with Dave about progress and what was being done and where they were at in the project.

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.

Evergreen has a professional and reliable team of people who do excellent work. If you want the best of the best in the area, select Evergreen to accomplish your insulation needs.

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.

I was extremely pleased with the professionalism and quality of service that I received from the Evergreen team. I met Richard to discuss options for insulation. I knew immediately that I wanted to do business with them because he did not try to over-sell extra services that I did not need. Dave was the project manager. He was not only kind, but very respectful of my home. I would highly recommend this company.

A thorough inspection of our (older) house and its energy needs. Competent and personable work crew.

Jacob Watson

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.

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!

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

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).
