Crawlspace Vapor Barriers & Ventilation

While often forgotten, your crawl space is a critical part of your home. It can affect your home’s comfort, air quality, energy efficiency and structural health. Crawl spaces can be quite humid. This can lead to mold and mildew growth and damaged insulation. 

Crawlspaces can attract insects as well. Insect infestation can lead to damage to your crawlspace's wooden structures.  

Your crawl space may also suffer from other issues, including poor ventilation and worn vapor barriers. Not correcting these problems can lead to expensive damage over time. 

If you need crawlspace services, contact the local experts at JAFCO. We offer services across the Seattle Metro Area, including Northgate, Washington Park and Central District. 

What is a Crawlspace? 

Crawlspaces are often installed in place of basements. They are a more cost-effective solution than a full basement. They are designed to house plumbing, HVAC systems and ductwork. They can also be used for storage. 

Most crawlspaces have vents to allow air in and reduce moisture buildup. 

What is a Crawlspace Vapor Barrier? 

A vapor barrier is typically a thick sheet of plastic that is installed on the floor of the crawlspace. It is also sometimes added to the walls as well.  

What is the Purpose of Vapor Barriers? 

Vapor barriers are designed to eliminate moisture and reduce humidity in the crawl space. Adding a vapor barrier diminishes the chances of mold and mildew growth, musty odors and wood rot. It will also keep out insects.  

Moisture buildup in your crawlspace can actually affect your living spaces. Floors can warp when there’s too much moisture in this area. So, it’s best to take steps to eliminate this problem in your crawl space. 

What is Crawlspace Ventilation? 

Besides a moisture barrier, it’s important to have proper ventilation in your crawlspace. Vents allow air to move throughout this enclosed area. Like the vapor barrier, ventilation reduces the chances of mold and mildew growth, wood rot, increased humidity and moisture buildup. 

Vents that lead to the exterior of the home or fans are usually used in crawlspaces. If these systems are lacking or damaged, they can lead to problems in your home. 

What Are Signs of Poor Crawlspace Ventilation? 

Common signs of problems include: 

• Mold and mildew growth 

• Musty smells in home 

• Damaged insulation 

• Increased indoor humidity 

• Condensation on surfaces
