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.
