Crawlspace Moisture Control Tips
A damp crawlspace can quickly lead to major problems like mold growth, wood rot, poor air quality, and even structural instability. Controlling moisture in your crawlspace is not only essential for your home’s longevity, but also for your family’s health. In humid regions like Chatham County and coastal Georgia, moisture control should be a year-round priority for homeowners.
Step-by-Step Guide to Moisture Control in Your Crawlspace:
1. Inspect for Signs of Moisture
Look for damp insulation, condensation on ductwork, visible mold, standing water, or musty odors. These are all red flags that water is entering or staying in the crawlspace.
2. Grade the Landscape Away from the Foundation
Ensure soil slopes away from the house to prevent rain from pooling at the foundation. Extend downspouts at least 4 feet away from the home.
3. Install a Vapor Barrier
Lay down a high-quality plastic vapor barrier over the entire crawlspace floor. Overlap seams by at least 12 inches and tape them down. This blocks ground moisture from rising.
4. Seal Foundation Vents During Humid Months
Open vents can allow humid air in. Consider sealing vents and using a crawlspace door that fits tightly.
5. Check Plumbing and HVAC Lines for Leaks
Dripping pipes or sweating ducts can increase crawlspace moisture. Repair or insulate these lines to reduce condensation.
6. Use a Dehumidifier
If humidity levels remain high, install a crawlspace-rated dehumidifier. Aim for a humidity level below 60 percent year-round.
7. Schedule Regular Inspections
Seasonal inspections help catch issues early. Look for torn vapor barriers, new moisture buildup, or rodent activity.
Maintenance Tip:
Install a wireless humidity sensor to monitor crawlspace conditions from inside your home.
