Wooden Floor swell up

You must to locate and inspect the area where the floor is swelled up. 1. The most common reason is lack or not enough big expansion gap around an edge of wooden floor ( that gap which has been covered by skirting or beading etc.) The common size is 10mm but best is to check floor manufacturer recommendation. 2.If en expansion gap is enough big to allow wooden floor expand freely other reason can be a heavy furniture which is stopping a wooden floor from expanding (that can be a piano , heavy cabinet , even sofa etc...) Wrongly installed flooring is fostering for such a symptoms. You can observe that type of swelling for example between legs of particular furniture or heavy item . 3.Another reason can be an excessive damp or water leakage under a wooden floor making a floor swelling up. How to avoid and react on above examples : 1. Cut an expansion gap around an edge of wooden floor 2. Not really much you can do for but to check if the flooring been installed within manufacturer recommendation and apply that ( or remove furniture somewhere else ;) 3. Disassemble the flooring where the problem occured and allow the subfloor to dry, reassemble wooden floor back to it normality but replace the broken planks with new one. I hope this helped.

hi there if the floor has swelled due to damp you can't just remove the planks and dry the floor out you will need to locate leak or a DPM " damp proof membrane " was not used in the first place, if this is the case the entire floor will need to be lifted and DPM will need doing slight bumps in the floor is due to no expansion gap, road humps are down to leaks or damp rising through the boards kind regards JD Flooring
