At Standard Exterminating Company, Inc., we know dirt floor crawl spaces aren’t just unpleasant—they can also threaten your home’s health and structure. Up to 60% of the air in your home comes from the crawl space, and excess moisture from exposed soil can lead to mold, pests, odors, and even rotting wood. That’s why crawl space encapsulation is essential for homeowners who want to protect their property, improve air quality, and reduce energy costs.
Crawl space encapsulation is the process of sealing your crawl space with a thick, durable vapor barrier that covers the floor, walls, and other exposed areas. This barrier prevents water vapor from rising into your home, stops pest infestations, and creates a dry, controlled environment.


We assess your crawl space to determine its condition and the best encapsulation strategy.
If needed, we install a sump pump to manage water and ensure proper floor drainage.
We seal the crawl space floor and walls with heavy-duty plastic, covering seams and obstacles with specialized tape and fasteners.
We close vents and gaps around pipes, sill plates, and hatch doors using caulk, spray foam, and WallCap molding to prevent unconditioned air infiltration.
To maintain humidity below 55% year-round, we install a dehumidifier, ensuring your crawl space remains dry and healthy.
