Work with a Second Generation Family Owned Nashville Crawlspace Company That’s Been Around Since 1975 and Will Continue To Be Around In The Future.

Crawlspace Vapor Barrier

Greg Lewis, the owner and founder of Crawlspace Makeover, started in his late father’s (Ken Lewis) janitorial business back in 1975 during high school. He worked for him during the summer seasons during college, and then went on to work for him full time after graduating. After graduating college (UTC), Greg moved on to work a few years for the Boy Scouts of America.

Greg and his father bought the Sears Carpet Cleaning franchise servicing the Nashville area in 1987, and successfully operated it until 1999 when they sold the company. It was while operating the carpet cleaning franchise, which utilized gasoline-powered super sucker trucks, that they began to learn about and service the extraction of water in water damaged homes and businesses. This led them to other related services in the industry such as mold remediation, and then on into managing indoor air quality by adding on an air duct cleaning division.

Since most air ducts in the Nashville and surrounding areas are in the crawlspace, which is usually a mess, a crawlspace renovation division was created. Check the homepage for more information about crawlspace vapor barrier near me.

The Definitive Guide to Installing Vapor Barriers in Crawlspace: Protecting Nashville Homes One Barrier at a Time

Welcome to the world of home maintenance, Nashville homeowner!

Ensuring your home remains a fortress against elements, especially moisture, is crucial in a place like Nashville, TN. One of the most effective ways to keep unwanted dampness at bay is to install a vapor barrier in your crawlspace. Confused about the process? Crawlspace Makeover is here to guide you through every step!

Why a Vapor Barrier? The Nashville Context

Before we dive into the ‘how-to,’ it’s essential to understand the ‘why.’ Nashville’s unique blend of warm summers and its location means humidity is a constant companion. And where does that moisture love to settle? Right in your crawlspace. Installing a vapor barrier can be the frontline defense against this.

Step-by-Step Guide to Install Vapor Barrier in Your Crawlspace

1. Gear Up: Safety first! Ensure you’re wearing protective gloves, a mask, and durable clothing to shield against potential irritants in the crawlspace.

2. Assessment and Measurement: Calculate the area of your crawlspace. This will help determine the amount of vapor barrier material you’ll need. Tip: It’s always better to have a little extra than to fall short.

3. Picking the Right Vapor Barrier: With several options in the market, ensure you select a durable, high-quality barrier, preferably a 6-mil polyethylene sheet, which is apt for most crawlspaces.

4. Prepping the Ground: A smooth installation starts with a clean surface. Remove any debris, sharp objects, or standing water from the crawlspace. 

5. Rolling Out the Barrier: Begin by rolling the vapor barrier over the crawlspace floor. The sheets should overlap each other by a minimum of 12 inches to prevent moisture seepage between them.

6. Seal and Secure: Adhere the vapor barrier to the crawlspace walls, using either an adhesive or mechanical fasteners. Ensure there are no gaps or bubbles.

7. Inspection: Once installed, check for any missed spots or potential vulnerabilities. Regularly inspecting your vapor barrier will ensure longevity and maximum effectiveness.

Local Touch, Global Standards: Why Nashville Homes Need Special Care

Every region has its peculiarities, and Nashville, TN, is no exception. Given our unique weather patterns and humidity levels, installing a vapor barrier in your crawlspace isn’t just an optional add-on; it’s a necessity.

With our in-depth knowledge of the local environment, Crawlspace Makeover ensures your barrier installation meets both local needs and global standards.

When to Use a Vapor Barrier With Insulation?

When to Use a Vapor Barrier With Insulation

The Comprehensive Guide to Using Vapor Barrier with Insulation: Elevating Crawlspace Protection in Nashville, TN

Your home is your haven, and ensuring its comfort and longevity is paramount. Among the numerous tools at your disposal, one combination stands out for its efficacy in both comfort and protection: using a vapor barrier with insulation. At Crawlspace Makeover, we believe in arming our community with the best knowledge. Dive in to discover when and why this powerful duo is essential, especially for homes in Nashville, TN.

Understanding the Duo: Vapor Barrier & Insulation

First off, let’s break down the basics:

Vapor Barrier: A material primarily used to resist the migration of moisture.

Insulation: A material designed to resist the flow of heat.

When combined, these two ensure your crawlspace remains dry and maintains an energy-efficient temperature, preventing heat loss and mold growth.

When to Use a Vapor Barrier with Insulation in Your Crawlspace

1. High Humidity Levels: Nashville’s unique geographical position means it experiences elevated humidity levels. If your crawlspace tends to be damp or if your home is built in a location with high-ground moisture, combining insulation with a vapor barrier becomes a necessity.

2. When Installing Fiberglass or Cellulose Insulation: These insulation types don’t resist moisture. Therefore, if you’re using them in your crawlspace, pairing them with a vapor barrier will prevent potential moisture damage.

3. Homes with HVAC Systems in the Crawlspace: For homes in Nashville, TN, where HVAC systems or ductwork run through the crawlspace, this combination prevents condensation build-up, ensuring the efficient running of your heating or cooling system.

4. Energy Efficiency Goals: Aim for those low energy bills? The combination of a vapor barrier with insulation can significantly increase the energy efficiency of your home, especially during those chilly Nashville winters or sizzling summers.

Benefits of Merging Vapor Barrier with Insulation

1. Mold and Mildew Prevention: By keeping the moisture out, this dynamic duo ensures that your crawlspace isn’t a breeding ground for mold or mildew.

2. Enhanced Comfort: Proper insulation, coupled with a vapor barrier, ensures consistent temperatures throughout your home.

3. Increased Home Value: A well-maintained crawlspace can significantly boost the value of your home in the Nashville real estate market.


4. Energy Savings: By preventing heat loss or gain in your crawlspace, you’re looking at considerable savings on your energy bills.

Why Nashville Homes Need This Dual Protection

With Nashville’s fluctuating temperatures and humidity levels, ensuring that your crawlspace is both insulated and protected from moisture is non-negotiable. The synergy of a vapor barrier with insulation caters precisely to Nashville, TN’s unique climate challenges.

What You Need to Know About Using a Vapor Barrier with Insulation

If you’re a Nashville, TN homeowner, knowing the ins and outs of crawlspace maintenance can make all the difference.  Using a vapor barrier with insulation is more than a protective measure; it’s a commitment to the longevity and health of your beloved home.

The Ultimate Guide to Installing Vapor Barrier on Concrete Floors: Mastering the Art with Crawlspace Makeover in Nashville, TN

A concrete floor, while being sturdy and long-lasting, can sometimes be the entry point for unwanted moisture, especially in spaces like a crawlspace. The solution? Installing a vapor barrier. Crawlspace Makeover is thrilled to offer you a comprehensive guide on why and how to install a vapor barrier on your concrete floor, tailored for our beloved Nashville, TN homes.

Why Install a Vapor Barrier on Concrete Floors?

Before we delve into the installation process, understanding the ‘why’ is crucial:

Moisture Control: Concrete, though seemingly impervious, can wick moisture. A vapor barrier prevents this, ensuring a dry floor above.

Mold Prevention: With moisture control comes a decreased risk of mold growth, a potential health hazard.

Enhanced Floor Lifespan: By keeping moisture at bay, you’re essentially prolonging the life of any flooring installed above the concrete.

Energy Efficiency: Believe it or not, a vapor barrier can contribute to a consistent internal temperature, thus aiding energy efficiency.

Step-By-Step: How to Install Vapor Barrier on Concrete Floor in Your Crawlspace

1. Preparing the Surface: Start by cleaning your concrete floor thoroughly. Remove any debris, dust, or protruding bits that could puncture your vapor barrier.

2. Measure and Cut: Based on your crawlspace dimensions, measure and cut the vapor barrier material, keeping some extra for overlaps and wall attachment.

3. Lay it Down: Begin unrolling the vapor barrier, ensuring it’s flat against the concrete floor. The goal is a snug fit without any air bubbles.

4. Overlapping: If your crawl space requires multiple sheets, ensure they overlap by at least 6-12 inches. This ensures no moisture seepage between sheets.

5. Secure the Barrier: Using adhesive tape or other securing mechanisms, attach the barrier to the crawlspace walls, ensuring it’s tight and leaves no gaps for moisture infiltration.

6. Inspect: Once done, do a thorough check for any potential weak points or areas that might be susceptible to damage.

What Mil Plastic for Vapor Barrier?

What Mil Plastic for Vapor Barrier in Nashville, TN

Choosing the Right Thickness: What Mil Plastic is Best for Vapor Barrier in Your Crawl Space? A Nashville, TN Insight

When diving into the world of vapor barriers for crawlspaces, one question often emerges above the rest: What mil plastic should you choose? At Crawlspace Makeover, we aim to provide clarity, specially tailored to the unique needs of homes in Nashville, TN.

Deciphering ‘Mil’ in Vapor Barriers

Firstly, let’s demystify the term. ‘Mil’ refers to the thickness of the plastic sheet and is equivalent to one-thousandth of an inch. Hence, a 6-mil vapor barrier is 0.006 inches thick.

Why the Thickness Matters

The thickness of your vapor barrier affects

Durability: A thicker barrier tends to be more resilient against punctures, tears, and general wear.

Moisture Resistance: The primary function of a vapor barrier is to resist moisture. A thicker barrier offers heightened protection.

Lifespan: Simply put, thicker barriers tend to last longer, offering better value for your investment.

Selecting the Best Vapor Barrier for Your Crawlspace

In general, a thicker vapor barrier is more beneficial. However, the optimal thickness for your crawlspace can be influenced by:

Ground Conditions: Rough and uneven terrains may require a thicker barrier for added durability.

Expected Traffic: If you anticipate frequent access or movement within your crawlspace, a thicker barrier can withstand more wear and tear.

Climate: Homes in areas with high humidity, like Nashville, TN, might benefit from a thicker barrier to ensure maximum moisture protection.

The Appropriate Thickness (Measured in Mil) Of a Plastic Vapor Barrier

What Mil Plastic for Vapor Barrier in Nashville, TN

For crawlspaces, choosing the right thickness of a vapor barrier is crucial to ensure moisture protection, durability, and longevity. The thickness of the vapor barrier is measured in mils (1 mil = 0.001 inch).

Here’s a breakdown:

Minimum Standard: The minimum recommended thickness for a crawlspace vapor barrier is 6-mil. This is often the basic standard in building codes.

Better Protection: For homeowners looking for better durability and longer life, 10-mil is a common choice. This thickness provides a good balance between performance and cost.

Premium Protection: If you’re looking for top-tier protection, especially in environments with high moisture levels or where there’s more foot traffic in the crawlspace, 12-mil to 20-mil barriers are often recommended. These barriers are more resistant to tears, punctures, and general wear and tear.

Reinforced Vapor Barriers: Some vapor barriers in the 12-mil to 20-mil range also come with reinforcement layers, making them even more durable.

Why Consider 13-20 Mil Vapor Barriers?

Crawlspace Makeover is utilizing 13-20 mil Vapor Barriers as the optimal choice for mil plastic in crawlspaces.

1. Strength and Durability
Firstly, let’s delve into the pros. The 13-20 mil vapor barriers are particularly known for their strength and robustness. This thickness ensures that they stand strong against common threats in a crawlspace environment. If you’ve ever had to deal with the frustration of a torn or punctured barrier, you’ll appreciate the resilience of these barriers. They can withstand a lot, making them perfect for crawlspaces that see a lot of activity or are more exposed to potential hazards.

2. The Cost Factor
On the downside, quality often comes at a price. These thicker vapor barriers are an investment. They typically come with a higher price tag compared to thinner options. However, while the initial investment might be more, it’s crucial to weigh this against the potential long-term savings. A more durable barrier can mean fewer replacements and less damage to manage in the long run.

The Nashville, TN Perspective

Given Nashville’s distinctive climate, combining warm, humid summers with wet seasons, ensuring optimal moisture protection for crawlspaces is paramount. Choosing the best vapor barrier for crawl space areas can prevent mold growth, structural damage, and even pest infestations. Thus, investing in a quality, thicker vapor barrier aligns perfectly with Nashville’s climatic demands.

The Impact of Mil Plastic on Vapor Barrier Safety

Deciphering the best mil for your vapor barrier might seem daunting, but with the right knowledge, the choice becomes clear. Nashville homeowners, by choosing the right thickness, you’re not just installing a protective layer; you’re ensuring the longevity and health of your entire home.

Where Does Vapor Barrier Go?

A Nashville Homeowner’s Guide

The concept of a vapor barrier, while technical, is pivotal in home maintenance, especially in the climatic conditions of Nashville, TN. Many homeowners, especially those new to crawlspace maintenance, often ask us at Crawlspace Makeover, “Exactly where does the vapor barrier go?” Well, consider this your comprehensive guide.

Understanding Vapor Barriers

First things first: a vapor barrier, as the name suggests, restricts the passage of water vapor. It’s a protective layer that prevents moisture from causing potential harm to your home’s structure and can help avoid mold growth.

The Right Places for Vapor Barrier Installation

Where Does Vapor Barrier Go in Nashville, TN

Crawlspaces: This is probably the first place you’d think of, especially given Nashville’s humidity. Moisture from the ground can seep into your home, making the crawlspace a prime area for a vapor barrier. The barrier typically lies directly on the crawlspace floor, covering the entire ground and extending up the foundation walls.

Walls: Particularly in climates like Nashville’s, where the balance of indoor and outdoor humidity varies greatly, vapor barriers can be used within walls. They’re typically positioned on the warm side (the interior in colder climates, the exterior in warmer ones) of insulation material.

Ceilings & Attics: For homes with unheated attics, placing a vapor barrier between the attic’s insulation and the home’s ceiling can be beneficial.

Floors: Especially when installed over concrete or in basements, vapor barriers can help prevent moisture from seeping up into your home.

Nashville, TN: A Special Case

Given our local climate, moisture issues can be prominent. While in some places vapor barriers in walls might be optional, many Nashville homes could benefit from them due to the unique humidity and temperature fluctuations. This makes understanding where the vapor barrier goes particularly vital for Nashville residents.

Ensuring Proper Overlap

It’s not just about the main placement. When laying down a vapor barrier in large spaces like crawlspaces, ensure that sheets of vapor barriers overlap. This ensures there are no gaps for moisture to penetrate. The overlapping sheets are then typically sealed with a specific tape for a watertight finish.

Vapor Barriers are Essential

Knowing where a vapor barrier should go is only the start.  Whether it’s safeguarding your crawlspace or other areas of your Nashville home, a well-placed vapor barrier is a boon.

The Nashville Guide: How to Put Down a Vapor Barrier in a Crawlspace

Taking care of your home in Nashville, TN comes with its fair share of challenges. Among these, the task of ensuring our homes remain moisture-free stands out, particularly when dealing with crawlspaces. At Crawlspace Makeover, we’ve been inundated with questions on how to effectively put down a vapor barrier in a crawlspace. So, let’s unravel the process step by step for our Nashville community.

Understanding the Importance

Before diving into the ‘how’, it’s essential to understand the ‘why’. A vapor barrier serves as a moisture-proof layer, preventing ground moisture from permeating your home. Especially in humid climates like ours in Nashville, this is pivotal in preventing mold growth and structural damage.

Step-by-Step: Laying Down a Vapor Barrier in Your Crawlspace


Clear the crawlspace of any debris, ensuring a smooth surface.
Measure the crawlspace area to determine the amount of barrier material needed.

Choose the Right Barrier:

For most crawlspaces, a thickness of 6 to 12 mil is sufficient. However, for better longevity, consider barriers that are 12 to 20 mil thick.

Start with the Walls: Attach the vapor barrier to the top of the crawlspace wall. Depending on the material of your walls, you can use furring strips, mechanical fasteners, or special adhesives.

Ensure the barrier extends a few inches above the ground level.


How to Put Down a Vapor Barrier in a Crawl Space in Nashville, TN

Lay the Barrier on the Floor: Roll out the vapor barrier across the crawlspace floor. Make sure it’s flat and smooth, removing any air bubbles.

When laying down subsequent sheets, overlap them by at least 12 inches. This ensures complete coverage without any gaps.

Seal the Seams: Use moisture-resistant tape to seal the overlaps. This creates a continuous barrier against moisture.

Secure the Edges: Where the barrier on the walls meets the floor barrier, ensure a good overlap. Seal this overlap with the same moisture-resistant tape.

Regular Maintenance: Periodically check the vapor barrier for any damages or tears. Quick repairs will ensure the barrier remains effective.

A Few Nashville-Specific Tips

Due to our specific climate conditions in Nashville, TN, consider investing in a high-quality, thicker vapor barrier that can withstand humidity fluctuations.

Whether you’re building a new home or considering upgrades to your existing one, you’ve likely come across the term ‘vapor barrier’. This component, especially in humid climates like Nashville’s, can be a real game-changer. But the question remains: Is a vapor barrier necessary? Let’s dive deep into this with insights tailored for the Nashville community and homeowners like you.

Understanding Vapor Barriers


Before we address the ‘necessity’, it’s crucial to understand what we’re discussing. In layman’s terms, a vapor barrier is a material designed to resist the passage of moisture. When installed in the right places, such as a crawlspace, it can protect your home from potential moisture-related damage.

Why Nashville Homes Should Consider Vapor Barriers

High Humidity: Nashville, TN is known for its warm and humid climate, especially during certain times of the year. This moisture, when left unchecked, can seep into your crawlspace and further into your home.

Mold and Mildew Prevention: Excess moisture is the primary catalyst for mold and mildew growth. A vapor barrier effectively blocks this moisture, ensuring your home remains mold-free.

Structural Integrity: Consistent moisture can weaken the foundational components of your home. 

So, Is a Vapor Barrier Necessary in Nashville?

Given our specific climatic conditions in Nashville, the answer leans toward a resounding ‘yes’. However, while many homes will benefit from it, the necessity varies:

Older Homes: If your Nashville home is decades old and you’ve been experiencing moisture-related issues or haven’t ventured into your crawlspace in a while, it’s wise to inspect and consider a vapor barrier.

New Builds: Modern homes in Nashville, TN, are often constructed keeping the local climate in mind. However, adding a vapor barrier can provide that extra layer of protection.

Location-Specific: Homes located near water bodies or in low-lying areas of Nashville may have a higher propensity for moisture intrusion, making vapor barriers almost essential.

Beyond the Necessity: Other Benefits

Energy Efficiency: Vapor barriers can enhance the efficiency of your insulation, potentially lowering energy bills.

Improved Air Quality: By keeping out mold and mildew, the air quality inside your home improves, promoting better health.

The Necessity of a Vapor Barrier: What You Need to Know

While the necessity of a vapor barrier hinges on various factors, for many Nashville homes, it’s a proactive measure that ensures longevity and health.

Structural Integrity: Moisture, over time, can erode the very bones of your residence. The vapor barrier acts as armor, safeguarding your home’s structural components and preventing potential damage.

Dynamics of Insulation and Vapor Barriers

When it comes to managing crawlspace conditions, especially in areas like Nashville, TN. As homeowners, we’re often confronted with several questions: Does the vapor barrier go over the insulation? We will now delve deeper into the subject of your home’s health and longevity.

Why Insulation Matters in a Crawlspace

Crawlspaces, especially in regions like Nashville, TN, can become susceptible to temperature fluctuations. Insulation acts as a shield, preventing heat loss during winters and keeping the space cooler during the summers. Proper insulation ensures energy efficiency and a comfortable living environment above.

Positioning the Vapor Barrier: Above or Below the Insulation?

Now, to the central query: should the vapor barrier go over the insulation? In most scenarios, especially in crawlspaces, the vapor barrier is typically placed directly on the ground and underneath the insulation. The primary reason is to prevent ground moisture from reaching the insulation. Wet insulation can lose its effectiveness and also become a breeding ground for mold and pests.

However, there are instances in wall constructions, especially in colder climates, where a vapor barrier might be installed on the warm side (interior side) of the wall, which means it goes over the insulation. This placement ensures that warm, moist indoor air doesn’t condense within the insulation during cold weather.

Pros of Placing Vapor Barrier Over the Insulation:

Robust Protection: One of the most significant advantages of this method is the barrier’s strength and durability. Placed over insulation, it is notably resistant to tears and punctures, ensuring maximum protection against moisture intrusion.

Enhanced Moisture Control: When the vapor barrier is positioned over the insulation, it acts as the final defense line against external moisture, especially in spaces like crawlspaces that are in direct contact with the ground. This can help reduce the likelihood of mold and mildew formation safeguarding the structural integrity of the home in this positioning.

Improved Energy Efficiency: With a vapor barrier over the insulation, there is an added layer that works to prevent temperature fluctuations. This can lead to more stable indoor temperatures and potentially reduce heating and cooling costs.

Cons of Placing Vapor Barrier Over the Insulation:

Higher Costs: Premium vapor barriers, especially those resistant to tears and punctures, can be more expensive than their thinner counterparts. When deciding on such an option, homeowners should weigh the benefits against the initial investment.

Potential for Trapped Moisture: If any moisture does make its way past the barrier, having it placed over the insulation can sometimes make it challenging for that moisture to evaporate, potentially leading to issues down the road.

Installation Complexity: Installing a vapor barrier over insulation may require more effort and expertise than placing it beneath. Homeowners should ensure they’re working with professionals familiar with the process.

Potential Risks of Incorrect Placement

Incorrect placement of a vapor barrier in relation to insulation can have several repercussions:

Moisture Accumulation: If the vapor barrier is positioned over insulation in a crawlspace, moisture from the ground can make the insulation damp, leading to decreased R-value (insulating power) and potential mold growth.

Compromised Structural Integrity: Damp insulation can cause wood rot, which might affect the structural integrity of your home over time.

Health Concerns: A moisture-rich environment is an invitation to mold and pests, both of which can lead to health concerns for the residents.

Does the Vapor Barrier Go Over the Insulation in Nashville, TN?

Uncovering the Mystery of the Vapor Barrier Over the Insulation

The correct location of your vapor barrier relative to insulation, particularly in critical areas such as crawlspaces, plays a critical role in the long-term and environmental health of your home. For Nashville, TN residents, considering the local climate and moisture patterns, the vapor barrier should ideally be placed beneath the insulation in a crawlspace. 

Always seek professional advice, such as the expertise offered by Crawl Space Makeover, to ensure your home remains a safe and comfortable sanctuary.

Answers to Your Questions

Subfloor Insulation: To Replace or Not Replace

Most of our Crawlspace Makeover projects will not include replacing subfloor insulation when it is removed for mold remediation purposes. There are several reasons for this. We have found it can create more problems than it purports to solve. In the Southeast, our climate is warm and humid most of the year. The only time subfloor insulation would be of any benefit would be in the winter, and even then, only a few days would make a noticeable difference in the temperature of the floor. The rest of the year, the insulation acts like a sponge to trap the humidity in the crawlspace. This creates several problems.

Why is mold growing in my crawl space?

Mold cannot grow without moisture or high humidity, so a thorough investigation is necessary to determine the cause of elevated moisture and water in the crawl space. In most cases, several minor conditions have contributed to creating a major problem:
  • Gutter and downspout extensions (a concrete splash block does not count). Here are the numbers: for every 1500 square feet of roof and inch of rain, 1000 gallons of water are channeled off of the roof. If the gutters do not catch the water, or the downspout extensions do not carry the water at least 6 to 10 feet away, all of that rain can make its way into the crawlspace
  • The drainage of the yard can slope toward the house and allow rain water to run into the crawlspace
  • Condensation on the ductwork, as described here, can contribute to high humidity and water puddles in the crawlspace
