Solutions for Damp & Musty Basements

Does your house seem musty or unusually damp? If so, you’re not alone — many homes here in Midcoast and Southern Maine often have excess moisture issues.

Typically, these issues can be traced to a basement with excess moisture. Moisture from the basement diffuses throughout the home, fostering mold growth and compromising your indoor air quality. Fortunately, you can eliminate basement moisture issues and improve the overall health of your home with basement encapsulation.

The Dangers of Excess Indoor Moisture

Many homeowners from Rockland down to the Portland area underestimate the dangers of excess indoor moisture. When left unchecked, this excess moisture not only harms your home but also undermines the health of you and your family.

In your home, high humidity and excess moisture can lead to a number of structural issues such as peeling wall paint, crumbling drywall, wood swelling, and frame rotting. Moisture can also accumulate on insulation, rendering it ineffective and detracting from the overall comfort and efficiency of your home.

Then there are health-related effects to consider. Mold and dust mites thrive in environments where the humidity level is above 50%. This means that excess moisture can quickly lead to poor indoor air quality, along with allergy symptoms such as coughing, sneezing, itching, and asthma.

Basement Encapsulation for a Clean & Dry Home

Your basement has a major influence on how comfortable, healthy, and efficient your home is, so it’s important to address any moisture issues if they are present. At Evergreen, we transform damp and musty basements with professional basement encapsulation.

Basement encapsulation eliminates basement vapor intrusion and air leakage through a multi-step process. This includes draining excess water using trenches and/or a sump pump; installing a heavy duty vapor barrier to prevent moisture infiltration; and securing the vapor barrier with spray foam insulation. Encapsulation may also involve radon mitigation and pouring a concrete slab to ensure indoor air is safe and healthy.

  • Greater indoor moisture control
  • Fewer moisture-related issues
  • More usable space in your home
  • Better indoor air quality
  • Reduced allergy symptoms

We had Evergreen energy do blow-in cellulose. I was very happy with the result. They tested with blower-door before and after. House is now MUCH warmer. Also, in the time since when I've had to open walls for various access, I've been impressed with how they got the insulation packed in everywhere. I'd use them again.

From beginning to end – that is from the moment Justin McEdward stepped into our home to assess our energy conservation needs until the crew left – the Evergreen Home Performance process went absolutely smoothly. Justin made a thorough inspection and took pictures with an infrared camera. His proposal described the scope of work in detail, and he explained what we could expect the proposed work to accomplish. Our proposal was forthcoming within a couple of days, and Justin was available to discuss it and answer questions.

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!

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.

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.

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.

Evergreen is a terrific company to deal with. Polite and efficient crews, meeting deadlines and major reduction in our heat bills. They corrected a lot of issues we suffered from doing work with a shoddy building contractor. We would recommend them to anyone.

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.

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 are thrilled with the job Evergreen did to transform our 213 year old home into a warm, draft-free, cozy space. The entire team led by Bruce was prompt, courteous, knowledgeable, and hard working. If Evergreen could transform our home in this way, we are sure they would make a comparable difference in YOUR home!

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.

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

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.

Emily Gallant

Evergreen completed the work at my home thoroughly and professionally. An inspector from Efficiency Maine came to inspect afterwards and described it as "state of the art" and "outstanding". The crew was very pleasant and considerate during the project. Their cleanup each day was perfect. Communications with the office were easy and reliable. I am very satisfied.

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