New karndean floor not level

Hi

Hope someone can help please

We have had a new karndean floor from a registered karndean shop / installer and the floor is not level, to the extent that our coffee table is rocking and also it is raised higher by our french doors for some reason.

When we walk over the floor barefoot in places it feels as though there is something under the plank as you can feel it?

The floorboards before the ply was put down was flat and in good condition, and I thought the main reason of plying the floor was to ensure that the surface was level etc to apply the karndean.

What is the solution as we don't really want to have them rip the floor back up, we have not paid the full balance yet only a significant deposit

Why not address your concerns directly with the shop. Giving them chance to explain/rectify which im sure they would be keen to do as there is still an outstanding balance. It would be extremely difficult and unfair for anyone on here to comment without seeing the floor.

 

The company have been out multiple times already to sort issues, this tops it off, they are due to come around again to take a look

I just want to know what would cause a sub floor not to be put down level?

 

pictures would help

 

agree
If you could put a few pics up it would help us on here to help you

 

Pics please

 

Thanks but if I put up pics it you would not be able to see that the floor is not level? From a picture it looks ok but the problem is with the sub floor not being level, causing the furniture to wobble (and its not the furniture)

 

If the company has used 6mm ply then this would only follow undulations in the floorboards. Ideally 9mm ply should have been used or a 6mm and level compound. These options should normally discussed prior to installation taking into account cost for yourselves, condition of floorboards, direction of light source etc. Saying that I know a lot of shops use a 6mm plywood and feather edge joints as standard practice
as mjfi said pics would help.
Could you take a pic with a straight edge/level laid flat showing difference in level

 

Thanks Dan

We just went with what they recommended which was 6mm ply as they said the floorboards were in good condition and they put some grey mixture between each sheet of ply?

Not sure how this can be resolved, would they need to pull the floor back up and refit the ply?

 

It's not the flooring company's job to level your subfloor? That is a major job that takes a fair but if estimating. All they have done is raised your floor by 6mm unless they have left something under the plywood??

 

Was the floorboards level? They can't of been as the plywood would follow the level. 9mm won't make a difference to the level. Ply will make the floor flat. You say your coffee table is rocking? Are the legs all the same length ? Sounds weird that the table is rocking even if the floor wasn't level.

 

I thought that the sub floor preparation was very important for good karndean install. If you have karndean installed onto a solid floor I thought they used self levelling compound so that its level. Our sub floor is a suspended floor which was in good condition and level, as we had no problems before?

If using 6mm or 9mm ply does not make a difference in levelling a floor then why bother even doing the subfloor work if it offers no benefit over the existing floorboards. And why do some installers insist on using 9mm ply when again it offers no benefit to the quality of the subfloor

Yes legs are the same length

 

If your sub floor is level then how can going up 6mn make it in un-level

 

The term self leveling compound is misleading. Its actually a smoothing compound to make the floor smooth enough to fit on. If you've a gradient on your floor it won't level it up.

 

dazlight - no idea

So is the expert opinion its one of those things and there is nothing that can be done? If this is the case then its very disappointing especially as karndean places itself in the luxury end of the marketplace

 

How do you know the floorboards were level? Was it tested before hand. The only think I can think of is the ply has delaminated in the patch were your table is.

 

They did use different plywood for the section where we are having the problems as they ran out when fitting it, but the new ply was the same thickness but different colour?

 

Run your hands over the floor an if you feel a bump then push it and see if it moves. What plywood did they use? Does it say on the estimate or invoice.

 

May have used a lesser grade plywood in the patch you say and may have delaminated. Was it screwed, nailed or stapled?

 

I think everyone seams to be reading to much into this one !! I wonder if you had a carpet down previously , that wouldn't show that your floorboards were slightly wonky ( making your coffee table wobble ) if thats the only issue stick a peice of card , paper etc under the leg ...hey presto problem solved
