Warm, humid air can enter a crawl space through open vents during summer, while cold air can enter during winter. These conditions can increase energy costs, create condensation, contribute to moisture damage, and make it easier for insects and other pests to enter the space.
A complete moisture-control plan may include a durable crawl space vapor barrier, airtight vent covers and doors, drainage where needed, and a properly sized dehumidifier. Together, these improvements help create a cleaner, drier, and more energy-efficient area beneath the home. Learn more about the installation steps below, or schedule a free crawl space inspection for your South Dakota, Wyoming, or Nebraska home.
Step 1: Install Airtight Crawl Space Doors and Vent Covers
Step 2: Remove any Standing Water in the South Dakota, Wyoming or Nebraska Crawl Space and Stop all Flooding
If a crawl space has experienced flooding, standing water and its source should be addressed before encapsulation begins. A drainage system can collect groundwater and direct it to a dependable crawl space sump pump, which then moves the water safely away from the home.
Plumbing failures can also introduce water into a crawl space. Because homeowners may not enter these areas regularly, leaks can go unnoticed for long periods. Repair active plumbing leaks before encapsulation and inspect the space periodically to help protect the finished system.
Step 3: Encapsulate the Crawl Space
Ground moisture can evaporate upward into a crawl space, raising humidity and contributing to odors, mold, and wood damage. Encapsulation helps block that moisture with a durable, tear-resistant vapor barrier installed across the exposed soil and foundation surfaces.
Blackburn’s system uses a seven-layer, 20-mil liner made with reinforced polyester cord and high- and low-density polyethylene. Its white surface reflects available light, making the crawl space brighter and easier to inspect. When termite-inspection clearance is needed along block walls, the installation can preserve a visible inspection area while sealing the remaining surfaces. Explore our crawl space products to learn more.
Step 4: Install a Dehumidifier in your Damp South Dakota, Wyoming or Nebraska Crawl Space
After a crawl space is sealed, a properly sized dehumidifier helps remove moisture remaining in wood and other materials while maintaining more consistent humidity. Blackburn installs Aprilaire dehumidifiers designed for automatic, energy-efficient moisture control. The system drains automatically and is selected to match the size and conditions of the crawl space. Learn more about our humidity-control and basement air solutions.

Crawl Space Encapsulation FAQs
What is crawl space encapsulation?
Encapsulation covers exposed soil and foundation walls with a durable vapor barrier to help separate the home from ground moisture.
What problems can encapsulation help address?
It can help control dampness, musty odors, condensation, and humidity that may affect the crawl space and the living areas above it.
Does a crawl space need drainage before it is encapsulated?
Standing water and active leaks should be addressed first. Depending on the home, drainage and a sump pump may be included before the vapor barrier is installed.
Is a dehumidifier still needed after encapsulation?
Some crawl spaces benefit from a properly sized dehumidification system to maintain healthy humidity after outside moisture sources are reduced.
How do I know what my crawl space needs?
An inspection can identify water, humidity, insulation, and structural concerns. Schedule a free crawl space inspection with Blackburn Foundation Repair.
