5 Benefits of Unvented Crawl Spaces

This past summer, we posted an article discussing the pros and cons of vented versus unvented crawl spaces. On Vancouver Island, unvented crawl spaces stand out as a clear winner, and today, we’re going to dive deeper into the benefits of unvented crawl spaces to explain why.

Benefits of Unvented Crawl Spaces

Here are just a few reasons why you should consider converting your vented crawl space to an unvented one:

1. Improved air quality

Vented crawl spaces allow outside air, pollutants, and allergens to enter the home. On the other hand, unvented crawl spaces prevent this air exchange and keep indoor air quality clean and healthy.

2. Moisture control

Vented crawl spaces are notorious for allowing moisture to enter and accumulate, which can lead to:

  • Mold growth
  • Wood rot
  • Other structural issues

Unvented crawl spaces use a vapor barrier and insulation to prevent moisture from entering, keeping your home dry and structurally sound.

3. Energy efficiency

Unvented crawl spaces reduce energy consumption by minimizing air leakage and preventing heat loss. This can mean lower energy bills and a more comfortable home.

4. Increased property value

With improved air quality, moisture control, and energy efficiency, it’s no surprise that unvented crawl spaces can increase your property value. Potential buyers will see the added benefits of an unvented crawl space and be willing to pay more for your home.

5. Environmentally-friendly

By reducing energy consumption, unvented crawl spaces positively impact the environment. They also eliminate the need for chemical pest control or mold remediation, making them a more eco-friendly option.


Did we mention that unvented crawl spaces can also be easier to maintain and provide additional storage space?
