Crawl Space Repair & Encapsulation in Greater St. Louis, Lake of the Ozarks, Springfield IL

The post-WW2 era saw a surge in the popularity of crawl space foundations for housing, as they offered speedier and more affordable construction than homes built with full basements. Unfortunately, builders at the time weren’t aware of some potential pitfalls associated with this type of structure—namely problems related to ventilation that could cause mold growth, structural decay, pest infestations and inefficient energy utilization. By understanding these issues now thanks to advancements in knowledge over time we can proactively take steps towards avoiding them going forward .

Midwest Basement Tech offers reliable solutions for all crawl space problems. Protect your home, your family’s health and lower your energy bills with our CrawlShield Encapsulation System and structural repair services.

Common Crawl Space Problems

Groundwater Intrusion

Effective crawl space drainage is crucial for a healthy and dry home. Unfortunately, many homeowners experience poor grading or lack of built-in drainage systems that pave the way for ground water puddles in their area—but Midwest Basement Tech can help with our state-of-the art solutions!

High Humidity

With no floor covering, crawl spaces are highly vulnerable to moisture issues. In addition, the vents initially put in place actually make matters worse by bringing humid air inside and blocking proper evaporation of water vapors. To combat this problem head-on, our experience team provides a comprehensive encapsulation system that create an environment impervious to any source of wetness.
