Crawl space moisture is a foundation problem waiting to happen
Water rises from the ground
Sandy fill and high water tables in coastal Georgia push moisture upward through the soil under your crawl space. This is not a problem you can "dry out" — it's a constant force that requires professional-grade waterproofing.
Moisture weakens wood support
Damp crawl spaces breed mold and rot in floor joists and support posts. This sagging transfers uneven loads to the foundation, causing the same cracking and settling problems that require pier repairs.
Energy costs and health risks
A damp crawl space forces your HVAC to work harder and can push musty air (and mold spores) into your living spaces. Encapsulation improves efficiency and indoor air quality.
How we encapsulate and waterproof crawl spaces
Inspection & moisture assessment
We measure soil moisture, relative humidity, and water pooling. Photos document the current state. This assessment tells us exactly what system you need — basic encapsulation, dehumidification, or interior drainage.
Install vapor barrier & insulation
We lay high-quality vapor barrier (6mil polyethylene or better) across the crawl space floor and seal all seams. We also insulate rim joists and band board to improve energy efficiency and prevent thermal bridging.
Seal foundation cracks & rim
Any cracks in the foundation wall or rim board are sealed with appropriate sealant. We address all air leakage points so the system remains effective year-round.
Install dehumidification if needed
For severely damp crawl spaces, we install a basement dehumidifier or crawl space-specific dehumidifier to maintain humidity levels below 60% — the threshold where mold and rot stop growing.
Frequently asked questions
Frequently asked questions
What is crawl space encapsulation?
Crawl space encapsulation is the process of sealing the crawl space with a vapor barrier and insulation to prevent moisture, mold, and pest infiltration. In coastal Georgia, this is critical because our sandy soils and high water tables constantly push moisture upward into the crawl space and foundation.
Why is crawl space waterproofing important in Savannah?
Savannah's sandy soils, high water table, and seasonal humidity create a perfect storm for crawl space moisture problems. Uncontrolled moisture leads to mold, wood rot, pest damage, and structural issues that spread to the foundation above. Waterproofing prevents these cascading failures.
How does crawl space moisture damage the foundation?
Moisture-laden air from the crawl space rises into the home, weakening wood support posts and floor joists. This sagging transfers loads unevenly to the foundation, causing settling, cracking, and the same repair problems we solve with piers and leveling. Prevention is cheaper than repair.
What does crawl space encapsulation include?
Our encapsulation includes vapor barrier installation (6mil polyethylene or better), insulation on band board and rim joists, dehumidification if needed, and sealing of rim board/foundation cracks. We also install interior drainage if water pooling is present. The goal is a dry, stable crawl space that protects the entire structure.
How long does crawl space waterproofing last?
A properly installed encapsulation system typically lasts 20+ years. We use durable materials and seal all seams and penetrations to prevent air leakage. Regular inspection of the vapor barrier and dehumidifier maintenance keep the system effective long-term.
Do you offer free crawl space inspections?
Absolutely. We provide free crawl space inspections with moisture readings, photographic documentation, and an honest written estimate. No obligation, and most inspections can be scheduled within the same week. Call 912-642-3890 to book.
