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

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.

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.

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.

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!

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.

I was very impressed by the professionalism of this company and the workers. Brian R. was very prompt in replying to my questions; the crew was meticulous in all parts of the work and attentive to the safety aspects concerning Covid; and Brian was extremely thorough in the final inspection. My attic is now snug and warm and I've noticed that the second floor is warmer as well.

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.

Great team!

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 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

Evergreen did a fantastic job insulating our 1930's home. The onsite team was professional, clean, and really just a joy to interact with throughout the process. A blower test at the end showed a significant decrease in air leakage. I highly recommend Evergreen.

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.

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.

Really great experience from start to finish with Evergreen. They helped us prioritize what needed to be completed first, and has made a significant difference in our hearing costs already. Plus they were really friendly and considerate to work with!

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.
