New karndean floor not level

good point made above.
what was down before the karndean went down?

 

It could be an off cut trapped under the plywood (or the pet hamster!) but they really should have noticed that when they were glueing the Karndean down. Which therefore strengthens the possibility of delaminating plywood in that section. Also, with regard to the Karndean itself unless its make up layers have separated then it's not the products fault. As everyone on here will tell you, preparation is far more important than the flooring part. The rise at your doors could be the plywood having overlapped the concrete plinth at the doors (providing you have this) seen this quite a few times, I usually cut the plywood to the concrete and screed to level with the plywood thus giving a level surface. As quite a few of the guys have said on here, you really need to show us some pics perhaps with some straight edge beside the areas to give us a reference.
Just out of interest, what kind of wobble are we talking about? 2-3mm could be lost simply by using the felt pads that came with your maintainence kit under the legs. These should be used anyway to prevent any accidental scratching of you renew floor. Obviously I wouldn't expect you to be happy if the bump is large and unsightly especially if it's a walk line. Also a very good point made with regard to your previous flooring, carpet and underlay do hide a massive amount of unevenness in a floor whereas hard flooring disguises nothing.

 

I went to a job the other day someone else has fitted. They had a decent sized lump under the flood the felt horrible. Cut the ply back and basically the chip board butted up there and was about 3-4mm higher. Right in the doorway. Customer never noticed it before.


If bet that this is the problem ur having.

 

Another point is if they are old floorboards and cupped then if no screed has been put on them before the plywood was fitted the plywood will follow the voids and look bumpy

 

Is there any other building work being done at your home?

 

This is why I prefer to put a flexible levelling compound down after the plywood. Even then you can't always get the subfloor completely level. Surely that's one of the pros of having a lvt... You don't have to build the floor up 30mm to get it flat like you sometimes do with ceramics.
I've got 3 bathrooms to do in camaro next week and as its a old house and there is carpet/underlay down I've allowed to fill with screed after the ply.

 

I think it could be a piece of off cut ply or nail/screw under ply like jambo and matt have suggested . I'm sure the shop will find and resolve the problem ... Let us know the outcome

 

Hi just registered as I also have problem with new Karndean floor. I bought from a designated stockist and had floor laid by their Karndean fitter. Some planks are raised at the ends( not laid flush) and are catching on bare feet others are not stuck right down as you can push them down ,there are a couple of gaps ,one right in the centre of the floor and one joint has a lump under it .It was laid over a chipboard type floor on plywood with adhesive , there are also a couple of `lines` appearing over the joints in the plywood,the retailer came and has asked the fitter to come back , the thing is how many of these things are normal for this flooring ,how picky should I be ,it was expensive after all !

 

Hi thanks for reply they're knight tiles KP91 and its the short ends sticking up I'm worried they will chip off as some corners are vulnerable,the tiles were delivered 2 days before and I took them out the boxes and spread them over the floor (we didn't tread on them at all) I shuffled them as I put them down ,the planks were in perfect condition but the boxes were well battered!I also kept the heating on for 24hrs before and after in the temp range karndean reccomended ,not sure what adhesive was used in a big white tub but he took it away.Will it be easy to slide the tiles up and down to correct the gap and to flatten the others,the retailer said it would be no problem! The lump under the joint appears to be a big lump of glue but I'm not messing with it ,will try to get pics later ,some of the unstuck edges are white so they don't look very nice ,Im waiting for contact from the fitter ,the retailer came and looked last friday

 

Where do I start on this one. ? I've got a bee in my bonnet with karndean(LVT ) at the mo. I bet this karndean fitter is of very poor standards. It's ok with people going to a reg. retailer for LVT but its a gamble who you actually get as the fitter. If the shop is choc a block with work then they won't want to lose business and use Whoever to fit it. I mean in your circumstance it's not acceptable at all. Nothin worse than poorly laid LVT. Had it recently where I gave a price for a job then never heard for months , turned out I had a job to do two months later a few doors away. So me being cheeky I knocked at the house to see if they actually had any fitted. Turned out that they choose a shop over me which was only £100 cheaper than me but they where having terrible trouble with them coz the fitter totally cocked up the floor . It was one of worse planking jobs I've seen. I compared quotes and I prices for 9mm ply then flex. They fitted 6mm with no feather . I had priced for ht addy they used ps. All planks gapping and planks lifting. All that hassle over a hundred quid. Rant over....... For now......and breath.

 

Images uploaded here http://imgur.com/a/i2P7Y first picture is repeated 3 times for some reason ,I'm no good at technology, had to get help with pics,will try to get better ones in daylight , I had 3 quotes, picked the middle one as it was well established local department store and I didn't know anything about the other 2 so thought it would be safer !! The ply deffo isn't 9mm more like 5 to 6mm

 

Why 9mm and flex Ste? Was the floor that bad?

 

Nearly always price. People generally don't seem to look at the detail of the quote and not bothered about who does it as long as its cheaper. a job I quoted on recently I did the quote to make the job right, they did their quote just to get the job, what can you do.

 

Hi daz spoke to you b4 but didn't explain fully. Yep the timber boards were horrendous . I priced for 9mm ply 101 which is very expensive then allowed for flex just in case. I explained this to them and said I could knock about £200 off price if I where to use normal ply, but didn't reccomend it. As others have said it's all about the price. Mad tho, if only they knew.

 

The clients are paying a high price now for going the cheap route thou...all for the sake a a poxy £100.00...NK1 is right though, most clients don't look at the materials detail in the quote, just the price...

 

Yeah he is right most don't look at details, but in this case I made a point of telling them the material details and saying make sure if you get another quote it's like for like and they still went with cheapest. Suppose it's like everything , some people don't listen.
