A vapor barrier is a key component to defend your home from excessive levels of moisture, humidity and mold growth. Each day, groundwater evaporates and rises due to the stack effect. This rise of water vapor penetrates the wood structure within the crawlspace while raising the relative humidity within the crawlspace and throughout your home.
StarDucts Crawlspace Enhancement installs the highest quality of vapor barriers (also referred to as a moisture barrier) installation. Our vapor barriers options range from 12-20 mil in thickness and are all string reinforced, made from 100% Virgin material, right here in the United States
- Is your crawlspace floor uncovered, just showing sand or dirt?
- If you have a vapor barrier currently, is it torn, rumpled, or not completely covering the ground floor?

- Is your vapor barrier a thin or clear material?

Benefits of our Seattle Vapor Barrier Installation and Repair Services
Limiting Dampness
Moisture and any water that enters the crawl space can seep through the dirt floor and surrounding walls. Mildew and mold grow rapidly as moisture and humidity linger in your dark and damp crawl space. Installing a vapor barrier ensures the moisture is controlled and concealed, preventing damage to the structure of your home, usually seen through rotting wood, rusted metal, and damaged drywall. The installation of this barrier keeps your crawl space dry and keeps hazardous fumes away.
Moisture Barriers Improve The Value Of Your Home
Mold can quickly and harshly impact your home. Mold is a type of fungus that thrives in moisture-rich areas and is more than likely to cause illness among anyone living in your home. Not only is mold only able to be removed by qualified professionals, but it impacts the insurability of your home. Preventing this type of damage is essential to ensure your home keeps the value for every dollar it’s worth.
Reducing Hazards Involving Wiring And Electrical
Moisture does not pair well with electrical systems. Moisture found in the crawl space can cause electrical shorts, rusted wires, and even fires. Vapor barrier installation helps to ensure all electrical and wiring materials are free from moisture. This helps to prevent increased risks of fire and electrocution.
Some common signs to look for that indicate moisture in your crawl space:
- Standing water in the crawl space
- Infestations of insects or other animals
- Peeling exterior paint
- Mold and mildew present on main floor of your home
- Lingering odor in or around your home
- Rusted piping in crawl space
