Excessive moisture in a conventionally vented crawl space is one of the biggest crawl space concerns. As moisture increases in or under a structure, this increases the possibility of attracting and creating an environment that supports wood destroying insects (like termites), creates a space that encourages mold growth, and makes the structure susceptible to wood rot. Additionally, the effects of the excessive moisture can negatively impact indoor air quality.

The crawl space in a home may be out of sight but the effects of excessive moisture in a crawl space should never be overlooked.

Clint Miller Exterminating protects your crawlspace. We provide moisture control by using a high quality, tear resistant 6mil vapor liner to cover the ground. This system, along with proper drainage and a form of mechanical drying will provide great moisture control protection.

Additionally, CME can seal your vents and set up a dehumidifier.

With a moisture barrier, your home is healthier and dryer.

  • Condensational moisture
  • High levels of humidity
  • Ground moisture vapors
  • Moisture intrusion from outside of the foundation walls

If you are having problems with moisture in your home, having CME install a moisture barrier can help mitigate this problem. You may need water management also to get the full moisture issue under control.

  • Dry crawl space surfaces
Factors affecting your estimate
  • Size of crawl space (square footage)

  • # of piers (including random placement vs. in rows)
  • Make sure crawl door is good, charge for repair if not sealed tightly.
  • Any trash in crawl? Must be removed!
  • HVAC ductwork locations
  • Piping
  • Cable lines and other wires
  • Any standing water?
