Crawl Space Dehumidification
Commercial-grade dehumidifiers keep humidity below 55%, preventing mold and protecting your home year-round.
What is Crawl Space Dehumidification?
Crawl space dehumidifiers are commercial-grade units designed specifically for the unique conditions of crawl spaces — tight spaces, temperature extremes, and continuous operation. Unlike residential dehumidifiers, crawl space models feature condensate pumps, automatic drainage, MERV-rated filtration, and are built to operate in low temperatures. Dehumidification is a critical component of any encapsulation system and can also be installed as a standalone solution.
Key Benefits
- Maintains humidity below 55% — the threshold for mold growth
- Improves indoor air quality throughout the home
- Prevents wood rot, rust, and moisture damage
- Reduces musty odors
- Energy-efficient continuous operation
- Self-draining — minimal maintenance required
Our Process
Humidity Assessment
Current humidity levels are measured to determine dehumidifier sizing needs.
Unit Sizing
Based on crawl space volume, moisture load, and climate, the right capacity unit is selected (typically 70-100+ pint/day).
Installation
The dehumidifier is installed on a stable platform with proper clearance for airflow.
Drainage Setup
A condensate line is routed to a sump pump, gravity drain, or condensate pump.
Monitoring
A hygrometer or smart controller is set up to monitor humidity levels and adjust operation.
Typical Cost
$1,500–$3,500

Crawl Space Dehumidification FAQ
For most crawl spaces, a 70-pint commercial unit handles up to 1,800 sq ft. Larger spaces or extremely humid climates may need a 90-100+ pint unit. Undersizing is the #1 mistake — always size up.
