Fixing vinyl floorboards that are cracked or separating

We would need to see a photo of the existing situation to make a judgement. Depending on the severity and extent of the “cracking” there could be an underlying cause that would need to be corrected first, such as an unlevel substrate or other site conditions causing the issue.

Hello Anonymous, Answers are never easy or straight forward, especially if ALL of the necessary information isn't known, because everything depends on the specific circumstances. There is no such thing as one answer fits all. Having written that, in most cases a qualified and great mechanic should be able to replace individual boards in such a way that you cannot tell it was done when (likely) he is finished. BUT, all of this depends on the exact details of what the problem is in the first place, what is the cause and in some cases full replacement may be the only useful or possible remedy. For example, IF the problem that developed is not installation or even vinyl plank (material) related. In most cases it is likely that the issue developed because the subfloor under the flooring is not close to the flatness(!, not "levelness") that is required for any expected performance. This usually takes a good professional (estimator or installer but never the "company") to bring to the attention of the owner of the place (home) AND for that owner to be willing to pay for whatever it takes to get the subfloor to comply with the (physical) warranty requirements, otherwise known as "proper or acceptable conditions". Not necessarily an inexpensive proposition, AGAIN depending on the local conditions and circumstances, type of subfloor, etc. Without an acceptable base one shouldn't expect the flooring to perform properly regardless of the dollar amount spent. The answer is yes to the question, but largely depending on the specifics!!

If you have the exact match for size and tongue and groove it's possible to change the damage pieces

Short answer: yes, it can be fixed one panel at a time — but only if the cause is right. Otherwise it’ll keep happening and you’ll wish you’d gone bigger. Make sure sub floor is flat and strong.
