August 30th 2023

Are you thinking of installing new flooring in your home or office? If you are, then you might be wondering the following: Is it OK to lay new flooring over old flooring?

It’s a common question, but the answer isn’t as straightforward as you might think.

When considering laying new flooring over old flooring, there are certain things that you need to take into account. Let’s explore the pros and cons of installing new flooring over old flooring and whether it’s a good idea or a bad one.

1. Understanding the Existing Flooring Condition

Before you decide to install new flooring over the old one, it’s crucial to understand the condition of the existing floor. If the old flooring is damaged or has become uneven over time, you should consider removing it completely to avoid further problems. Installing new flooring over a damaged or uneven surface can cause the new flooring to become unstable, leading to an expensive disaster down the line. However, if the existing floor is sound and level, then you can consider laying the new flooring over it.

2. Height Variations

Another significant consideration when laying new flooring over old flooring is the height variation. If you install new flooring over old flooring, it can cause a height variation, which can be dangerous and can lead to accidents. Therefore, it is essential to measure the thickness of both the old and new flooring before making a decision. If the height variation is significant, it might be better to remove the old flooring entirely.

3. Type of Flooring

The type of flooring you are considering installing will also impact whether or not you can lay it over the existing floor. If you plan to install carpet or vinyl flooring, then it’s possible to install it over the existing flooring. In contrast, other types of floors, such as hardwood, laminate, or tile, may require removing the existing floor to install the new flooring. It’s essential to understand the type of flooring you are planning to install before making a decision.

4. Moisture Levels

Moisture is a critical consideration when laying new flooring over old flooring. If the existing flooring has moisture issues, it can cause problems with the new floorings such as cupping, warping or swelling. Installing your new flooring over the old one can trap moisture, causing significant problems in the long run. It is advisable to get a professional opinion on moisture levels before proceeding with new flooring installation.

5. Cost and Time

Finally, installing new flooring over existing flooring can save a lot of money and time. Removing the old floor can be time-consuming and expensive, especially if you have concrete floors. By installing new flooring over the existing floor, you can save both time and money. Moreover, it’s also an eco-friendly and energy-efficient option since less energy and resources are used.
