Crawl Space Waterproofing
Stop water intrusion at the source. Comprehensive waterproofing keeps your crawl space dry year-round.
What is Crawl Space Waterproofing?
Crawl space waterproofing addresses water intrusion from multiple sources — groundwater, surface runoff, plumbing leaks, and condensation. A comprehensive waterproofing system may include interior perimeter drainage, sump pump installation, exterior grading corrections, downspout management, and wall treatments. The goal is to manage water before it becomes a problem, keeping your crawl space dry under all conditions.
Key Benefits
- Eliminates standing water and flooding
- Prevents structural damage from water exposure
- Stops mold growth at the source
- Protects against foundation erosion
- Works in conjunction with encapsulation for complete protection
- Addresses both groundwater and surface water intrusion
Our Process
Water Source Identification
Professionals identify all sources of water intrusion — groundwater, surface runoff, plumbing leaks, condensation — to design the right solution.
Interior Drainage
A perimeter drainage system (French drain) is installed along the interior foundation wall to capture and redirect water.
Sump Pump Installation
A sump pit and pump are installed at the lowest point to remove collected water and discharge it away from the foundation.
Exterior Solutions
Grading corrections, downspout extensions, and exterior drainage improvements prevent surface water from reaching the foundation.
Vapor Barrier & Sealing
A vapor barrier is installed to prevent ground moisture evaporation, and any gaps or cracks in walls are sealed.
Typical Cost
$3,000–$12,000

Crawl Space Waterproofing FAQ
If you have active water intrusion (standing water, visible leaks), you need waterproofing first. Encapsulation addresses moisture vapor and humidity. Many homes benefit from both — waterproofing to manage liquid water, then encapsulation to control moisture vapor.
