Concrete floor risen, too high meeting existing floorboards


We have had an extension built and the new area's floor is a few mm too high with the existing floorboards in the house. The person we got to do it was a total amateur and didn't have a clue what he was doing.

What can we do to fix it? The new room is quite large so I'm only concerned with taking some of the edge off where the two areas met.

Walking on the underlay you can notice the difference.

What is going to be the finished floor ? There are many economical ways to grind concrete if the concrete is to be the finished floor.

Your underlay seems fairly thick. It may compensate some for the difference, but it is hard to tell from the photos. I would think 2mm would be ok but not more!

I agree with Mike about taking down the height. Try a 4 ft straight-edge across the concrete to the wood floor. This will tell you how much concrete you need to grind off.

But there may be more! From what I see in your photo, it looks like the concrete is a bull-float finish. I would be concerned that you could have dips or bumps in the concrete. Try the same 4 ft straightedge across various areas of the concrete as well.

Another option may be to top off the wood floor to match the concrete level and feather it down over two feet or so.

Shooooey! That's a rough one, looks like it was finished with a chain saw.

I would be concerned about the overall irregularities. Agreeing with handy andy that a straightedge should be used to survey the entire floor. I'm betting there is plenty of grinding that needs to be done.

Laminate requires a "plane" surface. It doesn't have to be level but is should be flat. If that floor rocks and rolls out-of-plane I doubt your laminate will last. I would expect it to crack and break along the tongues over a time. The underlayment won't be much help.

Thanks for the replies. I passed on your advice to step father but he didn't take any warning. The floor has been laid despite my protest. It was his mistake for hiring someone who admitted to having little experience and in the end wanted to ignore the problem.

You actually feel seasick walking on it. One part creeks. It's embarrassing that it's been rushed through. Guests won't fail to notice. I'll have to learn to live with it.
