Can You Lay Laminate Flooring Over Carpet Underlay?

Laminate flooring has become increasingly popular due to its durability, ease of installation, and affordability. However, one common question homeowners face when considering laminate flooring is whether they can install it over existing carpet underlay.

In general, it is not recommended to install laminate flooring directly over carpet underlay. Here are a few reasons why:

Uneven Surface: Carpet underlay is designed to provide cushioning and support for carpets, resulting in an uneven surface. Installing laminate flooring over an uneven surface can cause the planks to buckle or warp, compromising their integrity.
Moisture Trapping: Carpet underlay can absorb and retain moisture, which can damage laminate flooring. Laminate flooring is not waterproof and can be susceptible to warping or swelling if exposed to excessive moisture.
Reduced Lifespan: Installing laminate flooring over carpet underlay can reduce its lifespan. The uneven surface and potential moisture problems can prematurely deteriorate the laminate flooring, leading to costly repairs or replacements.

Alternative Options

If you are considering installing laminate flooring, it is best to remove the existing carpet underlay and install a suitable underlayment specifically designed for laminate flooring. Underlayment for laminate flooring provides moisture protection, sound insulation, and a stable base for the laminate planks.

Here are some alternative options to consider:

Remove Carpet Underlay: Remove the existing carpet underlay and install an underlayment suitable for laminate flooring. This is the recommended method for achieving a durable and long-lasting laminate flooring installation.
Level the Surface: If it is not possible to remove the carpet underlay, you can level the surface by filling in any depressions or dips with a self-leveling compound. Once the surface is level, you can install an underlayment and then the laminate flooring.

Conclusion

While it may be tempting to save time and effort by installing laminate flooring over carpet underlay, it is not advisable due to the potential problems it can cause. By removing the existing carpet underlay and installing a suitable underlayment for laminate flooring, you can ensure a professional and long-lasting installation.
