Air bubbles under laminate flooring
Six months ago a leading hardware store laid laminate flooring throughout my flat. Ever since it has felt bouncy & spoungey. In the last month a number of the floorboards have risen up as if major air bubbles underneath & shifted. Not sure what to do - have contacted hardware store to no avail - any suggestions welcome as I am considering putting flat on market. Thank you

Hi Sarah the diagnosis is very simple. the floor has expanded as all mdf based laminate floors do, but not enough expansion gap has been left at the perimeter. To rectify this you or a carpenter will need to remove the beading or skirting and possibly any threshold strips and cut back the flooring to allow a gap of at least 6-8 mm up to 12mm.Cutting back laminate floor in situ can be done using a multimaster tool or if you have the patience a chisel.
It should not be necessary to remove and relay the floor as when you have eased the edge the floor will settle down.
I have done this on a number of occasions, one is noted on my feedback comments. I would suggest that you go back to the store who arranged the fit, and explain what I have outlined. You would expect them to rectify the problem.

sorry to hear about your laminate flooring. I would say that whoever laid your flooring didn't leave enough room between the edge of the flooring and the skirting board/wall. This is a common error and can be easily rectified. According to the weather and temperature, wood expands and contracts periodically, needing room to do so.
Therefore, your tradesman should simply take up the flooring around the edge of your room, shave a few millimetres off of it (just enough to allow for movement) and relay it.
Hope this helps. Tom, westberksconstruction.

Hi hope this helps.
For starters the floor shouldn't feel bouncy or spoungey , that to me either says underlay hasn't been fitted correctly, overlapping bits missing etc or you're sub floor wasn't level when they fitted the laminate . More thank likely floor isn't level which is a normal problem, which would require the laminate uplifted , then if a concrete floor a self levelling product laid or if wooden subfloor a ply base, the laminate can then be relaid .
With the floor board raising this will in most case be from the fact the laminate hasn't been fitted with the correct expansion gap. As the floor expands if the gap inst the correct size the laminate will eventually touch the skirting board , if it carries on expanding and now its touching the skirting, it needs to go somewhere so at the weak point where the boards click together they will start to rise. The beading needs to be all removed and edge laminate boards recut , problems will be where it goes under door frames etc, but as you have other problems it might be advisable to remove all laminate sort all problems and then refit.
You probaly won't get any luck with the Store they have you're money already so won't be worried about losing one customer . Sorry to be the bearer of bad news.
