Why Your Crawl Space Needs a Dedicated Dehumidifier
When you seal a crawl space, you eliminate the airflow that previously carried moisture out. Without active humidity control, a sealed crawl space can actually become more humid than before. Commercial-grade crawl space dehumidifiers are built to operate in tight spaces, function in low temperatures, run continuously with automatic drainage, and maintain target humidity year-round — none of which a standard household unit can do.
Right-Sized for Your Crawl Space
Using an undersized unit is one of the most common mistakes — it runs constantly, wears out faster, and never reaches the target humidity level. We size units based on your crawl space square footage, current moisture conditions, and whether encapsulation is already in place. For most Chester County homes we install units in the 70–100 pint/day range.
What's Included in Installation
- Unit selection and sizing for your specific crawl space
- Professional mounting — wall or floor bracket
- Condensate drain line routed to appropriate drain point — no bucket to empty
- Electrical connection to dedicated circuit
- Humidistat set to your target humidity level
- Test run and full walkthrough before we leave
Maintenance and Longevity
Commercial crawl space dehumidifiers last 10–15 years with basic annual maintenance. We offer annual service visits to keep everything running efficiently — and handle replacement when the time comes.
