Do I need underlayment for luxury vinyl flooring?

When you’re installing luxury vinyl flooring, you’re probably asking yourself, “Do I really need underlayment?” It’s a common question, and the answer isn’t as straightforward as you might think. In this blog, we go into the details so you can make the best decision for your home and budget. Whether you're looking for durability, comfort, or sound reduction, there’s a lot to consider.

 

What is underlayment, and why does it matter?

 

Underlayment is a thin layer of material installed between your subfloor and your flooring. It’s like a cushion, offering extra support and protection. Think of it as a buffer that helps smooth out imperfections on the subfloor.

 

Why does this matter? A poorly prepared surface can lead to problems later—like cracks, squeaks, or even shifting planks. The underlayment can also improve your floor's comfort, reduce noise, and sometimes even add insulation. But do all luxury vinyl floors need it? Well, not exactly. Let’s break it down.

 

Does your luxury vinyl flooring come with attached padding?

 

Here’s where things get interesting. Many modern luxury vinyl planks (LVP) or tiles (LVT) already have a pre-attached underlayment layer. If your flooring comes with this built-in cushion, you might not need a separate underlayment.

 

But here’s the catch: not all attached padding is created equal. Some provide excellent soundproofing and comfort, while others are simply there to help with installation. If you’re unsure, check the product specs or ask your flooring retailer for advice.

 

What type of subfloor are you working with?

 

Your subfloor plays a huge role in whether you need underlayment or not. Let’s look at the most common scenarios:

 
  • Concrete subfloors: Concrete is hard and unforgiving. If you’re installing luxury vinyl flooring over concrete, underlayment can provide a layer of comfort and help with minor imperfections. It can also act as a moisture barrier, which is crucial in basements or other areas prone to dampness.

  • Wood subfloors: Wood subfloors are softer than concrete but can still benefit from underlayment. It adds a soundproofing element, especially if you’re dealing with squeaky boards or an older home.

  • Existing flooring: Planning to install your luxury vinyl tile or luxury vinyl plank over existing flooring? Underlayment might not be necessary if the surface is smooth and even. However, if the current flooring has imperfections, underlayment can help create a better base.

 

The role of underlayment in soundproofing

 

Have you ever walked into a room with hard flooring and noticed the echo? That’s where underlayment can make a big difference. If you live in an apartment or a multi-story home, soundproofing might be a priority. Underlayment can help absorb sound, making your home quieter and more comfortable for everyone.

 

For instance, if your luxury vinyl flooring doesn’t have attached padding, adding an underlayment with soundproofing properties can be a game-changer. Products like cork or high-density foam are excellent options for reducing noise.

 

Moisture barriers: are they necessary?

 

If you’re installing luxury vinyl tile or luxury vinyl plank in areas prone to moisture—like kitchens, bathrooms, or basements—you might need underlayment with a moisture barrier. Luxury vinyl flooring is waterproof, but it’s not invincible. A layer of protection between your subfloor and flooring can prevent issues like mold or warping down the line.

 

Here’s the rule of thumb: A moisture barrier is non-negotiable if your subfloor is concrete or in a damp environment. Many underlayments come with built-in moisture barriers, so look for one that suits your needs.

 

Cost vs. benefit: is underlayment worth the extra expense?

 

Let’s talk money. Adding underlayment to your project increases the cost, no doubt. But is it worth it? That depends on your priorities.

 

The added expense could be worth every penny if comfort and sound reduction are high on your list. On the flip side, if you’re installing luxury vinyl in a low-traffic area or over an existing floor in good condition, skipping underlayment might be a smart way to save.

 

Keep in mind that not using underlayment when it’s needed can cost you more in repairs later. So, think of it as an investment in the longevity and performance of your flooring.

 

What happens if you skip underlayment?

 

Skipping underlayment isn’t the end of the world, but it can lead to a few headaches. Without it, you might notice:

 
  1. Increased noise: Your floor could feel hollow or noisy, especially if installed over concrete.

  2. Discomfort: Hard surfaces can be tough on your feet, especially in high-traffic areas.

  3. Durability issues: A lack of support could cause your luxury vinyl planks to shift or wear unevenly.

 

In short, underlayment isn’t always required, but it often enhances the overall experience of your luxury vinyl flooring.

 

Tips for choosing the right underlayment

 

Not all underlayments are created equal. Here are a few tips to ensure you pick the right one for your project:

 
  • Check manufacturer guidelines: Some luxury vinyl flooring warranties require specific types of underlayment. Always read the fine print.

  • Consider your needs: Are you prioritizing soundproofing, moisture protection, or comfort? Look for an underlayment that matches your goals.

  • Evaluate thickness: Thicker isn’t always better. Luxury vinyl flooring works best with underlayment specifically designed for its thin profile.

 

Do floating floors need underlayment?

 

Most luxury vinyl flooring is installed as a floating floor, meaning it isn’t glued or nailed down. Floating floors often benefit from underlayment, especially for soundproofing and minor subfloor imperfections. However, if your flooring comes with attached padding, adding another layer of underlayment could create instability.

 

Always double-check the manufacturer’s recommendations to avoid issues during installation.

The decision to use underlayment with luxury vinyl flooring depends on several factors: your subfloor, the type of vinyl flooring, and your specific needs. If your flooring has attached padding and your subfloor is smooth and dry, you might not need it. But for added comfort, soundproofing, or moisture protection, underlayment can be a valuable addition.
