Dehumidifiers

A Drier Basement — and Peace of Mind That Lasts

Even after drains, sump pumps, and vapor barriers are in place, humidity can still sneak in—and that can mean mold, musty smells, and moisture problems that linger.

That’s where professionally installed basement dehumidifiers come in. At Evergreen, we include dehumidification as part of our larger basement waterproofing systems—giving you lasting peace of mind and a space that stays dry, clean, and healthy long after the rain stops.

Even a Waterproofed Basement Needs Help Managing Humidity

Basement waterproofing and crawlspace encapsulation can address or mitigate the biggest sources of indoor water and moisture issues, but you’ll never completely be rid of humidity in Maine’s climate.

That’s where ongoing active control measures can help.

By pairing a dehumidifier with your sump pump, vapor barrier, or drainage system, we help you create a basement or crawlspace that stays dry, stable, and healthy—even when the weather changes.

Why We Install AprilAire Dehumidifiers

Portable dehumidifier units you can buy at big-box stores might help in a pinch—but they’re no match for the AprilAire professional-grade models we use:

  • High-capacity performance removes up to 100 pints of moisture per day
  • Designed to cover entire basements or crawlspaces
  • Can be paired with ducting for extended coverage
  • Improves air quality by reducing mold, allergens, and airborne viruses
  • Made in the USA and backed by a strong warranty

Keeping Your Basement—and Home—Healthy for the Long Haul

Basement moisture doesn’t just affect the basement. It impacts the air your family breathes, the comfort of the rooms above, and even the lifespan of your heating and cooling systems.

Dehumidifiers help:

  • Stabilize humidity and prevent mold
  • Protect finishes, furniture, and flooring
  • Improve air quality throughout your home
  • Ensure proper humidity levels are maintained after basement waterproofing upgrades

Ready to Make Sure Your Basement Stays Dry—for Good?

Humidity doesn’t always go away just because the water stops, as anyone who has spent an August in Maine knows. That’s why dehumidification is often part of the waterproofing and encapsulation strategies we design for your home—and why we recommend every Maine home has a dehumidifier to help with evaporation on open dirt floors in basements and crawlspaces, especially in summer!

During your free basement consult, we’ll assess humidity levels in your space and determine whether professional basement dehumidifier installation is the right fit for your Maine home.

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 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.

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.

Clayton Eames

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.

Bob O.

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.

RC Lations

We absolutely loved our experience with Evergreen. The team was incredibly kind, professional and great to work with. We're very impressed with the quality of work of the Evergreen team and how easy they made everything! Our house had barely any insulation ahead of this project and the results are amazing. Insulating the attic, walls and basement with Evergreen allowed us to tear a 50-year-old furnace, ductwork and oil tank out of the basement and now heat the home with new heat pumps. Evergreen also added 100 sq ft of clean, new storage space to the attic!

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

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

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.

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!

Loriel Van Dusen

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.

John E.

Boothbay

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

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!

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.

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.
