Each manufacturer independently sets the warranty period for its products and prescribes this period in the delivery contract. In most cases, this is much longer than required by the legislation of the Russian Federation (for example, for parquet boards of European manufacturers 25-30 years)
Please also note that when the buyer receives and pays for the product, the courier must check the packaging and appearance of the product for the absence of physical defects (scratches, cracks, chips, etc.) and the completeness of the kit. After the courier's departure, no claims will be accepted on these issues.
A detailed description of the warranty conditions can be found in the documentation for the purchased product and/or on the website of the relevant manufacturer.
