Laminate flooring edges are the most vulnerable parts of the plank. When moisture penetrates the surface, it typically seeks the path of least resistance: the seams. Because the core of laminate is made of compressed wood fibers, it acts like a sponge when exposed to liquid. Once water enters the joint, the fibers absorb the moisture and expand, a phenomenon commonly known as 'peaking' or edge swelling. This results in the characteristic raised seams that define a damaged laminate floor, which can never be sanded down or repaired like solid wood. Common sources of this damage include improper cleaning techniques, such as using an excessively wet mop. Water can also seep in from appliance leaks, pet accidents, or even high humidity if the home is not properly ventilated. Additionally, if the perimeter expansion gap was not left correctly or was filled with a rigid material, the floor cannot expand naturally, which can tighten the joints and make them more susceptible to moisture entry. To prevent swelling, strictly follow the manufacturer's cleaning guidelines—generally using a barely damp microfiber mop—and ensure that any spilled liquids are wiped up immediately. Never steam-clean a laminate floor, as the heat and moisture combination is a guaranteed recipe for core expansion.
