Dehumidifier
Crawlspace Dehumidifier Installation
Even after your crawlspace has been drained and encapsulated, moisture in the air remains a serious threat. Atlanta’s humidity levels are among the highest in the country — and that humid air finds its way into your crawlspace year-round. Without active humidity control, moisture buildup continues to fuel mold growth, wood rot, and poor air quality throughout your entire home. A professionally installed crawlspace dehumidifier solves this problem permanently by continuously monitoring and controlling the moisture level in your crawlspace air — 24 hours a day, every single day.
How Does a Crawlspace Dehumidifier Work?
A crawlspace dehumidifier works by pulling humid air from your crawlspace, extracting the moisture from it, and releasing dry, clean air back into the space. Unlike portable consumer dehumidifiers, our commercial-grade units are specifically designed for the demands of crawlspace environments — they operate continuously, handle large volumes of air, and are built to withstand the conditions found beneath your home. The extracted water is discharged through a drain line, so there are no buckets to empty and no maintenance interruptions.
- Controls humidity 24/7 — fully automatic, no manual operation needed
- Prevents mold & mildew from growing in your crawlspace and spreading upward
- Protects floor joists & wood structures from moisture-related decay
- Improves air quality throughout your entire home from the ground up
Every dehumidifier we install is sized specifically for your crawlspace’s square footage and humidity conditions. We set the unit to maintain the ideal humidity level — typically between 50% and 55% relative humidity — ensuring your crawlspace stays dry and healthy regardless of the season. Our team handles the full installation including drainage line routing, electrical connection, and system testing before we leave your property.
Where Can I Get Some?
Do I need a dehumidifier if I already have encapsulation?
Yes. Encapsulation stops moisture from rising through the ground, but humid air can still enter your crawlspace through vents, gaps, and air movement. A dehumidifier actively removes that airborne moisture and maintains the ideal humidity level inside your crawlspace — making it the essential final layer of your complete moisture protection system.
How is a crawlspace dehumidifier different from a regular home dehumidifier?
Consumer dehumidifiers sold in stores are not built for crawlspace conditions. They lack the capacity, durability, and continuous drainage capability needed to operate effectively in a crawlspace environment. Our commercial-grade crawlspace dehumidifiers are specifically engineered for constant operation, higher moisture extraction capacity, and long-term performance in tight, confined spaces — giving you reliable protection that a store-bought unit simply cannot provide.
How much does it cost to run a crawlspace dehumidifier?
A properly sized crawlspace dehumidifier operates efficiently and typically adds a modest amount to your monthly energy bill. However, the cost of running a dehumidifier is far less than the cost of mold remediation, wood rot repair, or structural damage caused by uncontrolled moisture. It is a small ongoing investment that protects you from very large repair bills down the road.
