Problems caused by a vented crawl space

Builders have always loved crawl spaces because they’re easier, faster and less expensive to build than full basement foundations. The traditional, “old-school” crawl space has openings or vents in crawl space walls that allow outside air to circulate below your living space. If insulation is installed, it’s usually in the form of fiberglass batts that are placed between crawl space joists. The crawl space floor will be soil or poured concrete.

Over time, a vented crawl space can lead to a variety of problems in the home:

  • High humidity and condensation on crawl space surfaces.
  • Damp, sagging fiberglass insulation.
  • Visible mold stains on crawl space surfaces.
  • Musty, moldy smells.
  • Rotted wood.
  • Cold floors upstairs during winter months.
  • High heating and cooling costs.
Crawl Space after encapsulation
From bad to beautiful. A vented crawl space with appearance and performance problems can be transformed by encapsulation using the CrawlSealâ„¢ System.

The solution: Seal the crawl space

If your crawl space has any of the problems mentioned above, don’t worry. Building scientists (the engineers who study how buildings perform) now recommend that a vented crawl space be sealed or “encapsulated” to isolate this under-house area from exterior temperature and humidity conditions. Crawl space encapsulation is a proven method for ending all the problems that plague vented crawl spaces. Ohio Basement Systems has the training, tools, and expertise to encapsulate any crawl space – no matter what size or condition.
