Crawl spaces are humid, dark places where mold grows, wood rots, and bad air accumulates. The smells and humidity from a neglected crawl space will eventually make it into your house above. These problems contribute to energy inefficiency, unnecessary home repairs, and even health problems.

Fortunately, crawl space encapsulation is a cost-effective process that locks out unwanted moisture and keeps your crawl space from causing complications. The experienced team at United Structural Systems offers crawl space encapsulation services for houses all throughout Tennessee.

What is Crawl Space Encapsulation?

Crawl space encapsulation is one of the most effective ways of preventing damages caused by indoor moisture. The process involves using a thick plastic vapor barrier to completely cover the interior of your crawl space. This barrier will be laid out over floors, walls, and sometimes the ceiling of your crawl space. Once the area has been sealed, a dehumidifier is typically installed in the encapsulated crawl space to further prevent excess moisture.

What are the benefits of crawl space encapsulation?

Encapsulating your crawl space provides several benefits from lowering your utility bill to protecting the health of your family. Here are some of the ways encapsulating your crawl space can be beneficial:

  • Improve your home’s air quality and humidity levels
  • Reduce the cost of heating and cooling your home
  • Prevent the growth of mold and mildew
  • Protect the wooden structure of your home from rotting due to moisture damage

Crawl Space Insulation and Encapsulation

If you’re considering crawl space insulation, the best time to do so is during the encapsulation process. Along with encapsulation, insulating your crawl space will further improve your home’s energy efficiency. Using the correct kind of insulation material will provide further measures to ensuring your crawl space doesn’t accumulate excess moisture and permit mold growth.

How to Know if You Need Crawl Space Encapsulation

Some of the most common problems that signal crawl space moisture problems are mold and mildew. However, you might not consider that the following issues might be signs that it’s time to think about crawl space encapsulation:

  • Sweat on your windows
  • Issues with insects and rodents
  • Cracks in your foundation
  • High cooling costs
  • Bad smell around your home

By encapsulating your crawl space, you don’t just fix the symptoms, like smells and high utility bills, you also solve the problem at its cause.

Four Steps to Control Humidity

There are four steps to controlling the humidity that builds up in crawl spaces.

First, drain any groundwater by installing a proper interior drainage system, if needed.

Second, encapsulate the crawl space to isolate it from the soil underneath.

Third, block moist air from getting into the crawl space by closing vents, joints, and gaps.

Lastly, install a dehumidifier.

Real Crawl Space Waterproofing

Many companies offer crawl space waterproofing but don’t do it to our standard. When we encapsulate a crawl space, we use 12-millimeter-thick plastic and seal any cracks, seams, and vents with spray foam and caulk to lock out all moisture from the surrounding atmosphere and soil. Doing it any other way may help reduce moisture levels in a crawl space, but it won’t make it truly waterproof.
