Your crawl space is an important part of your home, yet it is often overlooked or forgotten. Maintaining a clean and dry crawl space is essential to avoiding wood damage. An excess of moisture or humidity eats away at wood and eventually causes it to wear down. Thrasher Foundation Repair takes pride in being able to uncover the root of the problem and ensure that it will never happen again. Contact us today to schedule your free estimate.

Expert Crawl Space Insulation Services in Kansas City

Sealing off your crawl space to the outside elements will give you a clean and healthy home. Moisture in the crawl space allows for mold growth, dust mites, insects and other pests. Thrasher Foundation Repair offers crawl space encapsulation, vapor barriers, structural support and dehumidification.

Crawl space encapsulation

Protecting your crawl space from outside elements is a breeze with the crawl space encapsulation system from Thrasher Foundation Repair. Our system uses durable and proven techniques to give you back your crawl space for storage and keep your space clean and dry.

Vapor barriers

Vapor barriers stops the evaporation of moisture from the ground from entering the crawl space air. Since the vapor barrier prevents the passing of air, it can also turn your crawl space into a semi-conditioned space. This semi-conditioned space actually comes close to the temperature of your entire home, which makes your floors feel warmer and casue your energy bills to go down.

Structural support

Our Supportworks SmartJack System at Thrasher Foundation Repair is used as an additional structural support within your crawl space. It is used to lift up sagging joists and beams to be used alongside an existing column. The SmartJack System is a durable and permanent solution to your sagging floors above your crawl space.


Poor air quality decreases the value of your home. Thrasher Foundation Repair offers an energy-efficient crawl space dehumidifier to regulate air quality. This solution ensures that your home will have clean, dry air and protects against mold growth.
