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 redo the insulation in our roof. The team handling our project did a great job. They left the house spotless. We've already noticed the difference in how much better our house is retaining heat. I would definitely recommend and will use them for future projects.

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!

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.

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.

Last week, my oil company asked if we were using some other kind of fuel because our usage was so much less than they had expected We are very happy with the results; the house is much more comfortable

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.

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.

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.

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.

The crew members from Evergreen Home Performance each made sure to greet us every day, while maintaining their distance in this time of the pandemic. Their work took a total of nine days, spread over three weeks. Even though they were working in multiple rooms of our house, as well as the basement and attic, they were unobtrusive and always cleaned up after themselves every day. The on-sight manager kept us informed of their daily schedule so we'd know which parts of the house they'd be working on.

We had Evergreen Home Performance of Rockland come in to make our home more energy efficient, and what a TOP notch crew. Brian and his crew did an amazing job from start to finish. Very knowledgeable and professional. We would Definitely highly recommend this crew to anyone who is looking for energy efficiency in their home with a company that truly is an expert and knows how to do a quality job and truly cares about their customer.

Professional, friendly and hard-working staff. The product/approach they use for insulation is top notch. We felt the difference immediately, both from added warmth and eliminating drafts. The team and management were easily available to answer our questions or coordinate meeting times. Highly recommended.

Kevin J.

Yarmouth

We had Evergreen come out to our tiny old (100+ year old) house to see what they would recommend for decreasing our carbon footprint, saving money, and increasing our comfort in the cold season. Richard and Bryan were great to work with, patiently answering our many questions and walking us through multiple options. We could only afford to tackle a few areas this year; we ended up replacing some windows and having them weatherize the entire house.
