hi, could anyone tell me what might have caused the damage in the attached picture? The flooring has been down for years and there is no sign of water damage. Thanks!
Definitely moisture problem,nothing else is going to make a floor react like that, need to get some one with a meter to check sub floor out
Sometimes the entire surface of a swollen Parquet floor will expand and will severely rise up (see pic: www.floorfixer.co.uk/flood) as it becomes detached from the subfloor it was originally secured to. When each Parquet block swells by only a few millimetres due to dampness, it is very likely to create an overall expansion in this way throughout the entire floor. However, the drying-out process of swollen Parquet can be actually speeded up by removing the top layer of existing finish with coarse sandpaper on a belt-sanding machine. A commercial dehumidifier will then penetrate the bare wood far more rapidly if it is constantly left switched on in the room for a couple of weeks after our team has sanded the floor down to the bare wood.
You have to contact a company to fix it, it's probably a moisture prob like everyone here has mentioned.
Looks like your dpm has failed or a burst pipe underneath, needs a proper testing and at least a portion of the flooring removed for a Rh% test. Sent from my iPhone using Tapatalk
