Can You Install New Flooring Over Existing Flooring?

When it comes to home renovation, homeowners often ask if they can install new flooring over existing flooring. This approach is appealing because it can save time and reduce labour costs. However, not all types of flooring are suitable for this method. In this post, we will explore the options for installing new flooring over carpet, vinyl, laminate, and luxury vinyl tiles, while providing helpful insights and practical tips.

Benefits of Installing Over Existing Flooring

Installing new flooring over existing flooring has several advantages:

• Time and Labour Savings: Removing old flooring can be a heavy and messy job, often taking days to complete. When you install over existing flooring, you can skip much of this hassle, allowing you to focus on the fun parts of renovation, like decorating.

  
  

• Improved Insulation: If you lay new flooring over carpet or other cushioned materials, you could enhance sound and thermal insulation in your home. For example, homes with carpet underneath may experience a 15% reduction in noise levels, making your space cosier and more comfortable.

  
  

• Cost Efficiency: Removing flooring typically adds to your project budget. By leaving the old flooring in place, you cut down on waste disposal costs and can save between 15% and 25% on your total renovation expenses, especially if you have a limited budget.

  
  

Considerations for Specific Flooring Types

Carpet

Installing new flooring over carpet is a controversial choice.

Generally, it's best to avoid laying new flooring over broadloom carpet due to potential movement issues. This can lead to uneven surfaces and complications during the installation. However, if you have low-pile carpet that is clean, dry, and in good condition, it may be possible to install over it.

Keep in mind, though, that the extra height could affect the transition to other areas of your home. If you go this route, consider using a smoother surface beneath your new flooring to minimize any shifting.

Vinyl

If your existing vinyl flooring is in good shape, you can install new flooring over it.

Before proceeding, check for any damage or detachment that might impact the durability of the new layer. When using laminate or luxury vinyl tiles, it’s critical to ensure the old vinyl is adhered well and has a smooth surface. Any unevenness can cause unwanted problems later on.

Also, be aware of the thickness of the new flooring. If the combined layers are too thick, it could interfere with door clearance or create awkward transitions between rooms.

Laminate

You can install new laminate flooring over existing laminate, as long as the original surface is intact and well-maintained.

Before starting, check for uneven sections or damage that might affect your new flooring. If you’re in an area with changing humidity, be alert for moisture issues as well. Adding another layer will increase the floor's height, which can affect transitions to other flooring types in nearby rooms.

Luxury Vinyl Tiles

Luxury vinyl tile (LVT) offers excellent flexibility when it comes to installing over existing flooring. In fact, most flooring types can be laid over a suitable existing floor, provided the surface is sound, clean, and level.

With LVT, the installation method makes a difference. Click LVT, whether it requires a separate underlay or has a built-in one, can often be installed directly over existing floors, making it a convenient option for many renovation projects. However, glue-down LVT is a different story—it requires a perfectly flat and smooth subfloor, meaning it usually cannot be fitted over old flooring without proper preparation.

Thanks to its moisture resistance and durability, LVT is especially well-suited for kitchens, bathrooms, and other high-use areas. When properly maintained, it can last up to 25 years, offering long-term value and style.

Preparing for Installation

Before you begin installing, take a few steps to set yourself up for success:

1. Clean the Surface: Removing dust, dirt, and debris is crucial for ensuring that the new flooring adheres properly.

   
   

2. Inspect for Damage: Look for loose areas, major defects, and stains. Address any problems to ensure a smooth and lasting installation.

   
   

3. Consider Height: Think about the height increase and how it affects door clearance and transitions to adjacent rooms.

   
   

4. Moisture Testing: Conduct moisture tests to prevent future issues, especially in damp environments where mould could develop.

   
   

Final Thoughts for: Can You Install New Flooring Over Existing Flooring?

Installing new flooring over existing flooring can be a practical choice for many homeowners. However, the effectiveness of this method largely depends on the condition and type of the existing flooring and the new material you plan to use.

By assessing these factors carefully and following the necessary preparation steps, you can achieve a stunning new floor without the demanding work of tearing out the old one. Enjoy the ease of installation and the refreshed atmosphere of your space—no extensive removal required.

When in doubt, consulting a flooring professional can help you determine the best approach for your renovation project. Taking the time to ensure the process is done correctly will yield long-term benefits.
