Can I install my new laminate floor on top of my exisiting one?

When updating your home with new laminate flooring, you may wonder if you can simply install it over your existing floor. The answer depends on the type of floor you currently have in place. In this article, we’ll explore which floors are suitable for laying laminate on top, when it’s better to remove the old floor, and why your subfloor plays a crucial role in the final result.

Can you install laminate flooring over an existing floor?

When choosing a laminate floor, it’s important to understand the wear class. This classification is printed on the packaging and detailed in the technical guide, helping you choose the most durable option for your space. Wear classes combine residential and commercial use to indicate the suitability of the floor for various areas. For example, a wear class of 23/32 means the floor is designed for both home and commercial settings.

1. Carpeted floors: A definite no

Unfortunately, laminate flooring cannot be installed over carpet. Carpets are too soft and unstable, which can cause damage to the laminate's locking system. The softness of the carpet can create uneven surfaces, leading to gaps, movement, or even breaking the joints between laminate planks. If your existing floor is carpet, it's best to remove it and start fresh with a solid, even subfloor.

2. Tiled floors: Suitable with some preparation

Laminate flooring can be installed over tiles, provided the tiled floor is level and free of any damage. If the tiles are uneven or there are gaps between them, this could cause problems during installation. An underlay can help even out minimal height differences, but it’s important to assess whether your tiled floor offers a stable, flat surface.

3. Vinyl floors: A solid option

If your existing vinyl floor is hard and flat, it’s generally fine to install laminate over it. However, avoid installing laminate over soft vinyl or cushioned flooring, as these can behave similarly to carpets and cause damage to the locking system. As always, make sure the vinyl floor is level, undamaged, and securely fixed to the subfloor.

4. Wooden floors: Works if they are flat

You can also install laminate flooring over an existing wooden floor, but only if the floor is completely level. If the wooden floor is warped, uneven, or has loose boards, these issues need to be addressed first. Minor imperfections can be resolved with an underlay, which will help reduce noise and create a smoother surface for installation. However, larger issues such as uneven boards or significant damage should be fixed before proceeding.

The importance of a level subfloor

A flat, level subfloor is essential to achieving a successful laminate floor installation. If the existing floor isn’t perfectly flat, you risk damaging your new laminate or experiencing issues like creaking, movement, or uneven gaps between the planks.

The quality of your subfloor directly impacts the longevity and appearance of your new flooring.

Should you remove your old floor?

While it’s possible to install laminate over some existing floors, in many cases, removing the old floor will provide better results.

By starting with a new, flat base, you ensure your subfloor is solid, even, and free from any hidden damage that could affect the final installation. This may be a more time-consuming process, but it often leads to a longer-lasting, more stable flooring solution.

The role of underlay in installation

Underlay plays a key role when installing laminate flooring, especially over existing floors. It can:

• Level minor imperfections: Underlay helps smooth out small height differences, creating a more even surface for your laminate.
• Reduce noise: A good-quality underlay can help minimise sound when walking on your laminate, especially when installed on top of harder surfaces like tiles.
• Provide moisture protection: In areas with high moisture levels, such as kitchens or bathrooms, underlay can offer a barrier to protect the laminate from moisture damage.

However, underlay won’t fix major issues like significant unevenness or soft flooring underneath. In these cases, removing the old floor is usually the better option.

Conclusion: What’s the best approach?

While laminate flooring can be installed over certain types of existing floors, like tile, hard vinyl, and level wooden floors, it's essential to ensure that the surface is even and stable.

Carpeted floors, soft vinyl, and uneven wooden floors are unsuitable, and in most cases, it’s best to remove them and start fresh.

Additionally, using an underlay can help with small imperfections and noise reduction, making the installation smoother.

When in doubt, remember that the quality of your subfloor is key to achieving a flawless installation.

If you're unsure, removing the old floor and creating a level base will give you the best long-term results, ensuring your new laminate floor stays beautiful and durable for years to come.
