Common Problems with Vented Crawl Spaces

The alternative to an encapsulated crawl space is a vented crawl space. Vented crawl spaces purport to eliminate moisture, but they come with some risks. During the summer, vented crawl spaces draw warm, humid air, which can create mold. If you have a vented crawl space, this mold and its spores will circulate throughout your house. The same goes for moisture. But even when the temperatures begin to drop, you have cause for concern. Cold air can infiltrate vented crawl spaces, ultimately resulting in elevated heating and energy costs. For these reasons, among others, the U.S. Department of Energy has asserted that vented crawl spaces are inferior to their encapsulated counterparts. To avoid substantial issues, consider crawl space encapsulation via First Class HVAC.

Understanding Why You Need Crawl Space Encapsulation

Mold, moisture, and high utility bills may seem like issues that you can address at a later date. But you run the risk of more significant problems if you do not opt for crawl space encapsulation sooner than later. Your crawl space provides access to water mains, pipes, and electrical wiring for your home. It is critical to your regular routine that each of these elements remains in proper working order. By hoping for the best with a vented crawl space, you leave them vulnerable to breakdowns, mold, and other problems that will cost you money in the long run.

Professional Crawl Space Encapsulation Via First Class HVAC

When you are ready to take action to protect your home and its air quality, rely on the professionals at First Class HVAC for crawl space encapsulation services. We will efficiently close the foundation, walls, and floor of your crawl space to the outside, ensuring there are no wall openings. In the process, we will leave any existing insulation in your exterior walls or that which is level with the floor. We will remove all other insulation. The resulting crawl space will use a combination of mechanical drying techniques and air-sealing to control moisture.

Benefits of Crawl Space Encapsulation

There are a host of benefits associated with crawl space encapsulation. First and foremost, it protects the long-term dependability of your house and can improve the quality of air that you and your family breathe. Additionally, crawl space encapsulation can:

  • Eliminate moisture – An accumulation of moisture can cause structural concerns and weaken your foundation, but crawl space encapsulation prevents this.
  • Increase energy efficiency – With an abundance of vents in a crawl space, your HVAC system needs to work harder. Closing your crawl space to the exterior helps improve efficiency and lower your energy bills.
  • Prevent mold – Without vents, your HVAC system cannot circulate mold spores throughout your home.
  • Improve comfort – In addition to improving air quality by eliminating moisture, encapsulated crawl spaces can reduce humidity and improve comfort.
  • Keep unwanted pests away – When cold air sweeps through Delaware, critters and pests may invade vented crawl spaces. But they have no access points following encapsulation.
  • Increase home value – As a result of the benefits of crawl space encapsulation, your home’s value will increase as soon as First Class HVAC completes the process.
