A creaking parquet floor can have several causes. Often the unpleasant noise occurs in places that are very often committed and stressed. Cracks in the wood are also possible, caused by the change between heating air in winter and heat-free periods. Infiltclassifyable moisture can also cause the parquet to crack. Often, however, the substrate is also to blame – when moisture forms here and dries again, the parquet creaks. In case of doubt, you should hire a specialist to take a close look at the soil.
