Laminate flooring is a popular choice for homeowners due to its affordability and durability. However, like any flooring material, laminate flooring can develop gaps between the planks. Understanding why these gaps occur can help homeowners prevent them from happening in the first place.

One common reason for gaps in laminate flooring is improper installation. If the planks are not installed tightly enough, gaps can form as the planks expand and contract with changes in temperature and humidity. Additionally, if the subfloor is not level, it can cause the planks to shift and create gaps.

Another reason for gaps in laminate flooring is a lack of expansion gap. An expansion gap is a small space left between the edge of the flooring and the wall to allow for expansion and contraction. If this gap is not present or is not large enough, the planks can buckle or warp, leading to gaps.

Lastly, frequent spills or exposure to moisture can cause the planks to swell and create gaps. It is important to clean up spills promptly and avoid exposing the flooring to excessive moisture.

By understanding the common causes of gaps in laminate flooring, homeowners can take steps to prevent them from occurring. This can include hiring a professional installer, ensuring the subfloor is level, leaving an adequate expansion gap, and avoiding exposure to moisture.
