Recently, I was faced with this very question. My neighbor was undergoing a flooring renovation, switching from carpet to laminate, and he asked me if he could skip the arduous task of removing the existing carpet underlay. Intrigued, I started researching this question, and I was surprised to find a range of opinions on the matter. It was clear that there are valid reasons both for and against leaving carpet underlay in place, and I’m here to share what I learned.
Understanding Carpet Underlay and Its Purpose
Carpet underlay, also known as padding, plays a crucial role in the comfort and longevity of carpet. It serves multiple purposes:
- Provides Cushion and Comfort: It acts as a shock absorber, softening the impact of foot traffic and providing a more comfortable walking surface.
- Improves Sound Insulation: Carpet underlay helps reduce noise transmission, minimizing the sound of footsteps and other disturbances.
- Increases Carpet Life: By cushioning the carpet fibers, it helps prevent premature wear and tear, prolonging the lifespan of the carpet.
- Improves the Carpet’s Appearance: A good underlay helps the carpet lay flat and distribute the weight evenly, leading to a more consistent and aesthetically pleasing appearance.
However, the benefits of carpet underlay don’t necessarily translate to laminate flooring. Laminate is already a more rigid and resilient flooring material than carpet, rendering some of the advantages of carpet underlay less relevant.
Leaving Carpet Underlay: Weighing the Pros and Cons
The decision of whether to leave old carpet underlay under laminate flooring is a multifaceted one that requires careful consideration of potential benefits and drawbacks.
Potential Advantages:
- Cost Savings: Removing existing carpet underlay can add both time and cost to a flooring installation project. Leaving it in place can save you money and effort.
- Reduced Debris: Removing and disposing of old carpet underlay can create a considerable amount of debris. Leaving it in place reduces the mess and cleanup.
- Potential for Noise Reduction: While less effective than with carpet, some level of sound insulation could be achieved by leaving the underlay in place.

Potential Disadvantages:
- Uneven Surface: Old carpet underlay often becomes compressed and uneven over time, leading to an uneven surface that can affect the stability and appearance of the laminate flooring.
- Moisture Trapping: Carpet underlay is porous and can trap moisture, potentially creating a favorable environment for mold and mildew growth under the laminate flooring.
- Reduced Underlay Effectiveness: The old underlay may be compressed and less effective than a new underlay in providing cushioning and sound insulation for the laminate flooring.
- Subfloor Damage: If the old carpet underlay is damaged or deteriorated, leaving it under laminate flooring could lead to problems with the subfloor over time.
Expert Advice: When to Leave the Underlay and When to Remove It
While the decision ultimately rests with you, here are some expert-approved guidelines to help you make the best choice:
Leave the carpet underlay in place:
- If it is in good condition: The underlay should be free of tears, rips, or excessive wear and tear. It should also be relatively flat and free of bumps or dips.
- If you are installing a layer of new underlay: Adding a new layer of underlay over the old one can help address unevenness and provide added cushioning and insulation.
- If your subfloor is in excellent condition: A sound subfloor will minimize the risks associated with leaving old carpet underlay in place.
Remove the carpet underlay:
- If it is damaged or deteriorated: Damaged carpet underlay can quickly lead to problems with the laminate flooring, including unevenness and moisture buildup.
- If you are concerned about moisture: If your subfloor is susceptible to moisture problems, it is best to remove the carpet underlay to prevent moisture accumulation.
- If you are not confident in its condition: If you are uncertain about the condition of the carpet underlay, it is always best to err on the side of caution and remove it.
