How to level hybrid flooring?

fr97sk

Hi everyone!

We just got a new patio door installed and during the installation we realised our floor is not level hence the base of the door frame gap between the floor and base of the door frame is uneven.

Is there anything I can do to lift or fill the low areas beneath the flooring?

We have hybrid flooring.

Thanks.

Hi @fr97sk,

It looks like there is a noticeable fall in the floor in that section, and unfortunately problems like this need to be corrected before hybrid flooring is installed. The boards interlock, so to reach the low spot you would need to remove all boards back to a wall or starting point. Trying to lift only the boards near the door will simply move the height difference further along the floor and create another step where the boards meet the rest of the room.

To correct the issue properly, you would lift the flooring back to a wall, expose the subfloor, and use a self-levelling compound to bring the low areas up to the correct height. Once the subfloor is levelled and cured, the boards can be reinstalled so they sit flat against the new patio door. If the slope is confined to the doorway itself, there may be further investigation needed to understand why that section is dipping. But with the way hybrid flooring locks together, there is unfortunately no simple localised fix without pulling the boards back to the starting point. 

Let me tag @Nailbag to see if he has any thoughts.

Please let me know if you have any questions.
