This is one of the downsides to laminate flooring. It may be impossible to repair/replace it.
You didn't say what you have for flooring nor did you say how it was installed, but DEPENDING on what you have, you MAY be able to replace it. I say this because, today, people are 'interchanging' the word laminate for the word engineered, and vice-versa. Still, you may not be able to do what you want to do.
My best advice is to contact the installer or manufacturer to see what they say. Depending on your type of flooring AND how it was installed will dictate your option(s), if any. My best to ya and hope this helps.
