Moisture Control Process

We start with a free, thorough inspection to pinpoint exactly where and why moisture is collecting under your home. This allows us to recommend the precise Elizabeth City pest control and moisture solutions you need.

  • Musty odors inside the home

  • High indoor humidity
  • Condensation on pipes or ductwork
  • Mold growth
  • Wood rot
  • Increased pest activity

Why is crawl space moisture a problem?
Excess moisture can damage wooden floor joists, promote mold growth, reduce energy efficiency, attract termites and other pests, and negatively affect indoor air quality throughout the home.
Can crawl space moisture attract termites?
Yes. Subterranean termites are attracted to damp wood and moist soil conditions. A wet crawl space can significantly increase the likelihood of termite activity around your home's foundation.
What is a crawl space vapor barrier?
A vapor barrier is a heavy-duty plastic liner installed over the crawl space floor and sometimes walls to help prevent moisture from evaporating from the soil into the crawl space air.
Does a crawl space vapor barrier really work?
Yes. A properly installed vapor barrier can substantially reduce moisture coming from the ground and is one of the most important components of a crawl space moisture control system.
How long does a vapor barrier last?
High-quality vapor barriers can last 15 to 25 years or longer when properly installed and maintained. The lifespan depends on the thickness and quality of the material.
Can I install a vapor barrier myself?
While DIY installation is possible, professional installation ensures proper coverage, seam sealing, attachment to foundation walls, and integration with other moisture-control measures.
Is a vapor barrier enough to solve crawl space moisture problems?
Not always. While a vapor barrier blocks ground moisture, homes with high humidity, drainage issues, or water intrusion may also require drainage improvements, sump pumps, or dehumidification.
Why would I need a dehumidifier in my crawl space?
Even after installing a vapor barrier, humidity levels can remain high due to outdoor air infiltration or residual moisture. A crawl space dehumidifier helps maintain optimal humidity levels year-round.
