Should You Lay Underlayment on Original Flooring? The Surprising Answer

When embarking on a home renovation journey, one question that often arises is whether to lay underlayment on original flooring. This query can lead to considerable debate among homeowners, contractors, and flooring experts alike. In this article, we’ll explore the intricacies of underlayment, its benefits, and whether it’s necessary to install it over existing flooring during a remodeling project. By the end, you’ll have a clearer understanding of how to proceed with your flooring installation.

Understanding Underlayment

Underlayment serves as a critical layer between your original flooring and the new flooring material. Designed to enhance comfort, improve soundproofing, and provide a moisture barrier, underlayment can significantly affect the longevity and performance of your flooring choices.

• Soundproofing: Underlayment helps absorb sound, reducing noise transmission between floors.
• Moisture Barrier: Certain types of underlayment act as a barrier against moisture, which is particularly important in areas prone to dampness.
• Comfort: It provides a softer feel underfoot, enhancing the overall comfort of your flooring.

Now, let’s dive deeper into whether laying underlayment on original flooring is a wise choice for your remodeling project.

Assessing Your Original Flooring

Before you decide to lay underlayment, it’s crucial to assess the condition of your original flooring. Here are a few factors to consider:

• Condition: If your original flooring is damaged or uneven, laying underlayment may not solve underlying problems. In such cases, repair or leveling might be necessary first.
• Material: The type of original flooring significantly influences your decision. Hardwood, tile, and carpet each have different requirements and benefits from underlayment.
• Height: Adding underlayment increases the overall height of your flooring. Ensure this won’t cause issues with doorways, cabinets, or transitions to other flooring types.

When to Consider Underlayment

There are several scenarios where laying underlayment on original flooring is not only beneficial but may also be necessary:

• Installing Floating Floors: If you’re installing a floating floor, such as laminate or engineered wood, underlayment is often required to ensure proper installation.
• Soundproofing Needs: If you live in a multi-story home or an apartment, soundproofing can be a significant concern. Underlayment can help reduce noise transfer between floors.
• Moisture Control: For basements or areas with high humidity, a moisture barrier underlayment can protect your new flooring from water damage.

Types of Underlayment

Understanding the different types of underlayment available can help you make an informed decision. Here are the most common types:

• Foam Underlayment: Typically used for laminate and engineered wood floors, foam underlayment is lightweight, provides sound absorption, and is moisture resistant.
• Cork Underlayment: Cork is a natural insulator and is effective for soundproofing. It’s eco-friendly but can be more expensive than foam.
• Rubber Underlayment: This type offers excellent sound absorption and moisture resistance, making it suitable for various flooring types.
• Plywood or Particleboard: Sometimes used in specific applications, these materials add stability but may not offer the same benefits as other underlayment types.

Pros and Cons of Laying Underlayment on Original Flooring

As with any aspect of home renovation, there are pros and cons to consider:

Pros:

• Enhanced comfort underfoot.
• Improved soundproofing, particularly beneficial in multi-family homes.
• Moisture protection, extending the life of your new flooring.
• Improved thermal insulation, making your home more energy-efficient.

Cons:

• Increased height, which may necessitate adjustments to doorways or transitions.
• Additional cost to the overall flooring installation.
• Potential for trapping moisture if not chosen wisely, particularly with incompatible materials.

Personal Experience: A Case Study

In one of my recent home renovation projects, I encountered a classic dilemma: Should I lay underlayment on the existing tile flooring before installing laminate? The original tile was in excellent condition, but I was concerned about sound and comfort. We opted for a quality foam underlayment to address soundproofing while preserving the height of the floor. The result? A significant reduction in noise, and the new laminate felt much more comfortable underfoot. This experience reinforced my belief in the value of underlayment in the right circumstances.

Conclusion: Make an Informed Decision

In conclusion, whether you should lay underlayment on your original flooring depends on several factors, including the condition and type of your existing flooring, your specific needs for comfort and soundproofing, and the flooring material you choose for your renovation. While underlayment can enhance your flooring experience, it’s essential to assess your unique situation before making a decision. With a little research and careful consideration, you can achieve the perfect blend of aesthetics and functionality in your home renovation.
