You should decide by walking through the home whether the floor structure is a problem for you.
Floor not flat.
The question is is the floor flat.
You must check and control the flatness.
Flat means no significant high or low spots.
And don t forget to lay an underlay felt or a rubber composite type floor covering.
Here s how flat floor and level floor are different.
Also check for any damp areas this would swell the laminate if wood.
Slide the tongue of laminate being inserted into the laminate already on the floor.
No homes have perfectly flat level floors but many have floors in which the changes are so minor that they are not noticeable.
Near the door there is an empty space under the flooring so that the flooring bounces.
I would consult with nwfa the national wood flooring association for any additional symptomatic problems that may exist.
We have a new garage and 2nd floor above the garage.
The bulges probably mean that the floor is not flat which means starting over again i m afraid.
As you are moving the piece into the grooves on the flat piece lower the piece in your hand as you are pushing it together with the flat piece.
In the tile world the word flat means that the surface does not have any significant high or low spots and will yield a smooth tile installation with no lippage between tile edges.
Snap together the sides of the laminate pieces together by holding the piece you need to install upwards.
Before it was barely noticeable but now it bounces between 1 4 and 1 2.
Not being flat can cause problems with plank adherence to the floor hollow spots t g not fitting correctly etc.
