Crawl Space Repair Northern VA

Expert crawl space solutions rid your home of mold, moisture, and humidity while improving your home’s health and energy efficiency. Foundation Medix has several methods of resolving crawl space issues. Until problems exist, many homeowners give their crawl space very little thought, which is why it's important to call the experts. 


A crawl space, as the name implies, is limited in height and serves as the foundation for many homes. The crawl space foundation, rather than a slab foundation or full basement, is for easy access to plumbing and wiring when a repair may be needed. Often crawl spaces are bare dirt with no vapor barrier existing between the ground and the floor of your home. When water or moisture develop in a crawl space, serious problems begin.


Water or moisture inside of a crawl space can cause many different structural problems. Moisture will eventually evaporate, rise, and spread throughout the rest of the house. This can cause wood rot, mold, and other poor structural conditions. Moisture is able to enter into a crawl space through open crawl space vents. Any exposed dirt residing in the crawl space easily absorbs the moisture entering through an open vent. A number of issues contribute to crawl space moisture, including:

  • Humid or rainy weather
  • Poor drainage systems
  • Plumbing leaks


We are here to advise and educate you on all available crawl space solutions. Our crawl space experts will keep you informed throughout the entire process. We offer a number of solutions to your home's specific problems, including:

  • Install a concrete floor – Installing a concrete floor is one way to isolate your home from increased mold, radon, and humidity levels associated with an exposed dirt or gravel crawl space.
  • Crawl space drainage – We will drain unwanted water from your crawl space with a sump pump.
  • Conditioned crawl space – We can connect a vent from your HVAC system to the crawl space. Fresh air will constantly be entering your crawl space, which will create healthy air flow.
  • Crawl space dehumidification – We will remove moist, damp air from your crawl space with the installation of a dehumidifier specifically designed for this purpose.
  • EZ Breathe (crawl space) – We can install an EZ Breathe (Crawl Space) device to remove moist, damp air from your crawl space.
  • Crawl space insulation – We will treat crawl space walls by installing a specialized radiant reflective insulation which lowers energy costs and retards future mold growth.

To cover the dirt/gravel floor in the case of insulation, we install a 20 mil. reinforced polyethylene vapor barrier. It is extremely durable and puncture resistant, as it is 300-600% thicker than a standard plastic vapor barrier a typical builder would install. All seams are sealed air tight with our specialized high strength tape.
