Crawl Space Dehumidifiers: Control Humidity and Prevent Long-Term Damage
Moisture in your crawl space doesn’t just stay below your floorboards. It rises into your home, feeding mold growth, musty odors, and even wood rot. And because most crawl spaces go unchecked for years, high humidity often goes unnoticed. Until it’s caused real damage.
A properly installed crawl space dehumidifier keeps that hidden moisture under control. At Force Basements, we install professional-grade systems designed to work with your encapsulation or moisture barrier setup, keeping humidity in check and protecting the air, structure, and insulation inside your home.
How Force Basements Handles Crawl Space Dehumidifier Installation
We install commercial-grade dehumidifiers that are designed specifically for crawl spaces — compact, powerful, and built to run efficiently in damp, low-clearance areas.
1. Free Inspection & Moisture Assessment
We begin by inspecting your crawl space, identifying where water is entering, measuring moisture levels, and assessing any existing damage. We’ll also ask about your home’s water history.
2. Immediate Water Removal (if needed)
If your crawl space has standing water, we’ll use commercial-grade pumps and vacuums to safely and quickly remove it, minimizing further damage.
3. Identify the Cause
Once the crawl space is clear, we trace the source of the water — whether it’s foundation cracks, clogged gutters, poor exterior grading, or a failed sump pump system.
4. Install & Configure the System
We install the crawl space dehumidifier and set humidity targets — usually around 50–55%. The system runs automatically and includes continuous draining.
5. Optional Integration

FAQs About Crawl Space Dehumidifier Installation

In many cases, yes. A vapor barrier blocks ground moisture, but a dehumidifier controls airborne humidity that can still enter from walls or ductwork.
What type of dehumidifier do you install?
We install professional-grade crawl space dehumidifiers with automatic drainage, high-capacity filtration, and low-clearance profiles.
Will a crawl space dehumidifier affect my entire house?
Yes — by lowering humidity at the source, it improves overall indoor air quality and comfort throughout the home.
