Mistake Number 1: Making Use Of The DIY Crawl Space

If you have decided to try out the DIY method, let us tell you that it comes with many risks. These dangers usually range from minor inconveniences to major repairs required. It includes:

  • Compromised structural integrity
  • Trapped moisture
  • Inadequate ventilation

So, instead of trying to do this work on your own, you should take the assistance of a professional expert who has the skills and expertise to carry out this work flawlessly.

Mistake Number 2: Utilizing Improperly Vented Dryers

A flooded or humid crawl space can attract many significant problems to your house. Ventilation in your crawl space aids in preventing moisture from being trapped in your crawl space. But, it would help if you never attempted to fix this issue by yourself. Many homeowners have thought that incorporating more fans or vents will help fix the problem of moisture and humidity in their crawl space.

But, the reality is the opposite of this. If you try to add additional vents by yourself, it can work to increase the humidity levels in your crawl space. Even worse, the added vents could compromise the foundation of your house.

Again, venting dryers or other applications into the crawl space can lead to significant humidity issues in your house. Improperly vented dryers can even pose a fire risk to your home. So, it would help if you never tried to vent your dryer into the crawl spaces. Instead of trying out a DIY crawl space ventilation, it is best to leave this work in the hands of experts.

Mistake Number 3: Not Insulating The Crawl Space

Another most common mistake that individuals often make while encapsulating their crawl space is that they choose not to insulate the crawl space. But, you should essentially refrain from making such kinds of mistakes. Whenever you decide to sell your house, and if it is not appropriately insulated, it can lead to many other issues.

So, you have to insulate it anyway to safeguard yourself from these issues. Again, by having an insulated crawl space, you would be able to save energy and enjoy comfort. Also, note that the building code does require insulation of the crawl spaces.

Mistake Number 4: Using Fiberglass Between Floor Joists

Many homeowners make the mistake of using fiberglass in between the floor joists. But, they should never do this unless they have chosen not to seal and dehumidify or condition their crawl space. It is a good idea to avoid utilizing fiberglass at all.

It is because the performance of this material is poor whenever it comes to crawl space insulation. Again, the results are minimal if this material is installed in an unconditioned vented space.

But why does this happens? Well, it’s because the material is responsible for soaking the moisture, thereby losing its R-value in the process. And ultimately, it turns out to be useless as encapsulation material. The weight of the water again causes sagging of the fiberglass and thereby opening holes in the encapsulation blanket.

Another essential thing to note in this aspect is that fiberglass batches are generally held together with the help of a urea-based adhesive. So, whenever adhesive, fiberglass, and moisture combine, they create a haven for mold. Due to this particular reason, you should avoid using fiberglass.
