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

Evergreen did a fantastic job replacing 28 windows in our house. They were friendly, courteous, and very detail oriented. Brian did a great job planning, estimating and executing the project. Our energy use has dropped significantly since the work was done.

Our house still the most efficient home we’ve ever lived in. And we have you folks to thank for that! A special howdy to Brian Robinson please!

Bruce O’Donal and Eva Butler

The Evergreen team was amazing from initial assessment and planning to the crew that came to complete the work. Our basement encapsulation is the best money we've spent on our house by far. The work was thorough and high quality. And what a wonderful group of people to work with. I highly recommend Evergreen!

Martha Bracy

My experience with Evergreen was excellent. From their thorough and thoughtful initial consultation to their detailed post-work visit, the team was professional, knowledgeable, and responsive. Their workmanship was top notch. Our home is now much warmer and more efficient. I highly recommend their services!

Awesome company. It was a few years ago that they did the audit and then we commissioned them to do the work. We subsequently sold our house and moved to South Africa, but their level of service and expertise will live on.

Odette Brown

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.

I would recommend Evergreen wholeheartedly because of their professionalism, their follow through, and thoughtful project planning.

We couldn't be more pleased with the easy, professional, high-value service from Evergreen. Having purchased an older home that had been in our family for generations, we needed multiple upgrades, including insulation throughout. Evergreen insulated our attic with blown-in cellulose, built a new, super-insulated attic hatch, sealed off the old one (which was just a piece of plywood in a closet ceiling), and also talked us through our best options to upgrade our heating system given the plans we have to add onto the house.

Evergreen has just completed Phase 2 of 2 at my home. They are professional, hard-working and courteous. They communicate well..no surprises. They've gone above and beyond to make my home comfortable and were very respectful of my home.I recommend them unequivocally!!!Many thanks to Brian, Brian, Rick, Eddie, Dawson and the rest of the Evergreen crew!!

David Henry Feldman

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.

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

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 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!!

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.

Adrienne Harkavy

Great company. Very professional and thorough. They take the time to explain everything and offer options to fit your budget. Wonderful experience from start to finish.
