Why You Need Vapor Barriers for Your Crawl Space

Why You Need Vapor Barriers for Your Crawl Space
Jun 25, 2019

Crawl space vapor barriers are tools used to prevent moisture evaporating from your crawl space’s floor and seeping into the rest of your home. Acting as a barrier against vapor, they help in keeping your home comfortably dry.

Here’s why you need vapor barriers for your home:

Reduced Dampness

With water and moisture seeping through the floor and walls of your crawl space, the area is prone to dampness. The high moisture-density in the air also makes for a humid and moist environment inside. This enables the growth of mildew and mold, which thrive in dark and damp environments. As a result, the structure of your house is adversely affected as mold attack the drywall and wooden surfaces in your home.

A crawl space vapor barrier can prevent this. By sealing the entrance, it keeps the area dry and moisture-free. This helps in keeping mold away from your home.

Temperature Regulation & Efficient Energy Consumption

The humidity level of your home determines the hotness and coolness of the place. The more humid your crawl space is because of moisture seepage, the hotter your home will be. This will ultimately lead you to keep your HVAC system switched on for longer in an attempt to bring down the temperature, which will use up a lot of fuel and energy.

Vapor barriers help your home remain energy-efficient. Since they’ll keep moisture out, your home’s temperature will be better regulated and won’t reach an exceedingly high level. Sealing off the crawl space using these will also bring down the energy costs by lowering the operating time of your HVAC system.

Reduced Risks of Electrical Hazards

Since vapor barriers keep the crawl space dry, they also reduce the chances of electrical shorts and related hazards. With your electrical wiring kept safe from moisture and dampness, you’re automatically lowering your risk of electrocution or a fire at your home.


Stable & Strengthened Foundations

Your house is as strong as the foundation holding it together; including the pillars, concrete slabs, and walls. If moisture seeps in, it can cause severe damage to the structural framework of your house, weakening your foundation and threatening your home’s safety.

Typically, this requires a lot of repair work which can create a dent in your budget. However, by having a vapor barrier in your crawl space, you can easily avoid this situation altogether. Vapor barriers protect your home from structural damage and keep its stability intact. Even if you’re situated in an area that receives rainfall all year round, you won’t have to worry about rotten wood and weakened concrete thanks to crawl space vapor barriers!
