Crawlspace vents are often recommended by various home contractors and pest control companies. Vents are offered as a supplementary service to the homeowner. But, oftentimes, what sounds like a reasonable solution often causes more problems than what it fixes.
Your home’s structural stability and the air inside are greatly affected by moisture content. Excessive moisture weakens wood, facilitates mold growth and can contribute to allergies (and the growth of more and more allergens!).
Remember: Moisture Content in the Air is a function of Relative Humidity. The higher the humidity, the more moisture in the air and the more problems that ensue.
Not only does high moisture air contribute to structural issues, its also much harder to heat and cool, thus placing a strain on your home comfort system. While the soil around your home remains a relatively stable 55 degrees, when you vent:
- on cold days, you’re letting more cold air into yourhome
- on wet days, you’re letting more wet air into your home
- on hot days, you’re letting more hot air into your home
All of the large shifts in temperature mentioned above are related to condensation and humidity. Rather than helping air achieve a consistent, dry temperature, vents actually contribute to large humidity swings.
If you have a vented crawlspace and want to learn more, contact our office for a free inspection. We’ll review your property and help you understand the extent to which these issues are affecting your home.
