I noticed this cracking sound when stepping on certain area of my laminate floor, I think it is the area where the planks are joint together.

What happened to my laminate floor?

 

It has gained moisture and is now locked in from lack of an expansion space somewhere.

Or the subfloor was not as flat as specifications require.

 

Thanks for your reply. Is it possible to fix this problem?

 

Not without removing the floor. And filling the low spots and grinding off the high spots.

 

If installed over concrete slab, vapor retarder should have been used. Whether concrete or wood subfloor, a flat surface is required.

 

Thank you both for your time.

 

DId you just install this floor? I had the same problem when my Pergo floor was first installed about a year ago, the floor made crackling and popping sounds all over the floor, I was really stress out at the time and was ready to throw the whole floor out the window!

When the weather got hotter and more humid the problem became even worst, Im guessing the wood was contracting and making the joints to tight causing them to click together, this continued through the whole summer of 2004, when winter finally came around the cracking and popping sounds totally dissapeared, when the summer of 2005 finally came around I thought for sure the floor would start acting up again, but to my surprise the cracking never came back.

Im not sure if this is your problem or not but if it is hang in there, when winter hits the wood will expand and it will release the joints, im not really sure why my floor doesnt have the problem anymore but I couldnt be happier, the cracking sound was driving me crazy.

 

Candy means the boards will shrink during the winter heating(drying out) season.

 

Thanks for sharing this for me
