Crawl Space Sealing - Encapsulation Frequently Asked Questions

It is not uncommon for homes in Peach Tree Corners and Johns Creek to have damp crawl spaces and it may even have pooling water after it rains. The process of waterproofing or sealing a crawl space is called encapsulation. Sealing the crawl space waterproofs the surface area between the ground and your floor of the crawl space with a thick, durable, and airtight synthetic sheeting that's proven to seal out the excess crawl space moisture seeping into the underside of your structure.

In Peach Tree Corners and Johns Creek, crawl spaces may be neglected and don't receive the proper maintenance. They are usually thought of as in-home spaces or buildings where old Christmas ornaments and things are stored away. Because of this, the crawl space can become a feeding ground for distressing activities, including mold, bugs, standing water, damaged vents, and moisture.

Now, let’s answer some frequent questions about sealing a crawl space

How to know if you have a crawl space moisture problem

Typical crawl space dampness issues include rotting wood, damp insulation, and termites. One may be able to see mold growth in the crawl space or dampness on ductwork.

What is the cause of a damp crawl space?

Many crawl spaces have exposed dirt or clay floors, which allows ground moisture to evaporate into the area under the property, increasing the crawl space moisture levels. These issues can cause high moisture levels in the air and other parts of the home if it does not have a vapor barrier.

Sloped ground, foundation cracks, and lack of rain gutters can also contribute to crawl space humidity control issues by leaking rain or groundwater into the crawl space.

Lack of ventilation in a crawl space compounds the problem by producing a mixture of warm and cool air, causing surface condensation, which increases the amount of crawl space dampness under the property.

Does crawl space encapsulation increase the Home's value?

Sealing off the crawl space helps control wetness and ultimately increases the property's worth. While it is not as elaborate as other property improvements, crawl space encapsulation is essential for your property.

How long does the sealed crawl space protect against moisture?

Generally, most waterproofing companies will offer a warranty of between 15 and 20 years for a standard crawl space encapsulation project. However, if the humidity levels are decent and no catastrophic events such as flooding occur, a correctly encapsulated crawl space can last for more than 20 years.

Does encapsulation require a dehumidifier?

Crawl space encapsulation does not address the dew point. Even if the crawl space plastic was a barrier to ground moisture, dew point could still be a problem, and the dehumidifier is needed to control dew point.
