Common Causes of Hardwood Floor Buckling
Various factors can contribute to hardwood floor buckling. Understanding these factors allows for accurate diagnosis and targeted solutions. Moisture intrusion, problematic subfloors, and structural settling are key contributors to this issue.
Moisture Intrusion
Moisture is a significant culprit behind hardwood floor buckling. Excess moisture, whether from leaks, humidity fluctuations, or improper installation, can cause wood to swell and expand, leading to warping and buckling. This is especially prevalent in basements, bathrooms, or areas prone to water damage. The severity of the problem depends on the amount of moisture and the duration of exposure.
