Crawl Space Vapor Barrier Nashville TN

Don’t let Music City become Mold City. Protect your home with a crawl space water vapor.

Walking along the Cumberland River makes for a peaceful walk on a nice day, whether alone or with family and friends. It provides an attractive backdrop for Nashville’s Country Music Hall of Fame and Museum and demonstrates the beauty of nature in the middle of city life.

But the river also brings water vapors into the air.

With an average daily humidity of 70%, Nashville, TN has a lot of water in the air. The 615 is no desert. The humidity can make it feel sticky outside, but can also keep the skin from feeling too dry.

Inside our homes, most of us have A/C (this is the South after all) which dries out the air and keeps the inside from that sticky feeling. But the A/C only dries out the air inside the house. About 17% of newly constructed homes have crawl spaces in the Nashville area. The water vapors in the air can make their way into the crawl space and cause long-term damage.

Damage in the crawl space from water vapors can range from mold growth to pest infestation to more severe water damage to the subfloor.

Zipcodes affected by water vapors in the Nashville area include:  37201, 37204, 37205, 37215, 37220, 37221, 37011, 37014, 37015, 37027, 37040, 38401, 37055, 37062, 37067, 37066, 37072, 37075, 37076, 37082, 37087, 37115, 37122, 37127, 37135, 37138, 37146, 37167, 37174, 37179, 37388

Crawl Space Vapor Barrier Nashville TN

Most homeowners worry about mold growth when a flood occurs or if they are directly on the water, but mold can grow even from the humidity getting trapped underneath your home. Mold especially loves a dark, moist crawl space. The water vapors in the air turn your crawl space into a tropical getaway for mold.

But who cares if mold is growing outside your home?

The crawl space may not be contained within the walls of your home, but it does affect the health and safety of the inside of your house. The air in the crawl space can make its way into your home through the floor and subfloor if no crawl space vapor barrier exists. Just like the moisture from a wet towel will seep through a shirt and onto your skin, the moisture in the crawl space air seeps through the floor and into the air you breathe.

This means any mold, fungus, or even viruses growing in the crawl space air can get into the air you breathe inside the home.

These microorganisms can then cause issues such as difficulty breathing, sneezing, coughing, headaches, or illness. For children and adults with allergies and asthma, these symptoms can be even worse or possibly life-threatening.

Since the issue is coming from beneath, changing the air filter won’t solve this problem. Your home needs a crawl space vapor barrier to stop harmful organisms from entering your home uninvited.

What is a Crawl Space Vapor Barrier?

Crawl Space vapor barriers are thick plastic sheets that protect your crawl space from water vapors that may try to enter your crawl space.

Vapor barrier sheets are impermeable, meaning they do not allow any moisture, mold spores, or other small organisms into the crawl space.

Mold needs moisture and nutrients to grow. Installing a crawl space vapor barrier not only reduces the moisture but also takes away the nutrients mold needs.

At Crawl Space Vets, we use 14 mil 100% woven reinforced vapor barriers. Extremely strong and long-lasting!

Mold can still grow on plastic if there is dirt, food particles, or other substances it can use for nutrition. That is why you may see mold grow on plastic containers in the kitchen if you leave food in it too long. When you get a crawl space vapor barrier installed with Crawl Space Vets, we will ensure you start with a clean vapor barrier so that mold cannot grow.

And it’s not just mold that we’re keeping out. Pests also love moist, dark environments.
Nashville is home to a wide variety of creatures including spiders, mice, cockroaches, and more. While these animals have important roles in the environment, they are not pleasant to have in or underneath your home. From the crawl space, these pests can enter your home through existing cracks or openings they make themselves.

How Do I Know If I Need a Crawl Space Vapor Barrier?


Protecting your crawl space from moisture, mold, and pests is essential to the health of your household. Protection measures might include complete waterproofing, encapsulation, vapor barriers, or crawl space dehumidifiers.

In the Nashville area, homes with signs of mold growth, pest infestation, or excessive moisture will benefit from a vapor barrier. Additionally, if you are in a flood zone, the rising river could enter your crawl space and cause significant and long-term water damage.

A crawl space vapor barrier protects against water damage from both humidity and flooding underneath your home.

The crawl space was designed so that flooding is less likely to enter your home. However, water that makes its way underneath your home can start to attract mold, pests, and even viruses. Yes, even viruses. Droplet or airborne viruses (including the coronavirus) can grow in the humid environment underneath your home.

We want to help protect you and your family from these viruses with a crawl space vapor barrier that keeps the space under your home so dry it’s deadly to these dangerous viruses.
