It is not always necessary to dismantle the entire parquet. Depending on the varnish used, it is possible to replace some of its parts. For example, if only part of the parquet is spoiled, and the other is still as a new one, you can simply replace its defective part without damage to the rest of the coating. One way or another, the repair will be cheaper than a complete replacement.
