How Crawl Space Encapsulation Improves Indoor Air Quality?

Posted on May 10, 2023

Do you know what’s lurking in your crawl space? Many homeowners are unaware of the potential hazards in this often-overlooked area of their homes. Poor indoor air quality is a primary concern that most of them deal with. And the main reason behind this is inadequately encapsulated crawl space. This comprehensive blog post will discuss how you can boost indoor air quality by opting for a crawl space encapsulation service.

So, keep reading this from the start to the end if you are ready to breathe healthier and cleaner air in your house.

How Crawl Space Encapsulation Works?


Crawl space encapsulation is the procedure that involves sealing off the area beneath a building from the outside environment. 

Creating a barrier between the crawl space and the external environment helps prevent the entry of mold, moisture, and other contaminants. It is done by sealing off any vents, installing a vapor barrier on the floor and walls, along with adding insulation.

During the crawl space encapsulation procedure, a dehumidifier is often installed to maintain the desired humidity level effectively. It plays a crucial role in preventing moisture buildup, which can result in mildew and mold growth and cause damage to the structural integrity of the house. It also aids in effectively controlling humidity levels in the crawl space.

However, to ensure the maximum effectiveness of this procedure, one should ensure that the installation process is carried out correctly. And it is where a professional crawl space encapsulation company can help you. 

Some of the approaches they are most likely to adopt are ensuring that the barrier is airtight and does not contain any holes or gaps, as that could allow moisture to seep in. They are also focused on addressing existing water damage and removing any debris or insulation, if present, to prepare the space beforehand effectively.

Now, let’s move on to talking about the critical benefits of crawl space encapsulation as follows:
