If your wood floor is already down this might mean you have to pull up the section that squeaks to repair the subfloor and then put down a new section of flooring.
Tile floor cracking sound.
Because you say that the tile floor in question is on the second floor i am going to assume that the tile is installed over a wood sub floor.
Sometimes you might walk across your floors and hear a popping or creaking noise.
Grout hugs the edges of floor tiles and sometimes seamlessly blends with the tiles exposed surface.
In far more instances the crack was caused by anomalies under or around the tile.
Floors that make a popping sound.
Occasionally a crack along the joint between grout and tile appears to be a crack in the tile s surface.
This can occur when a mortar bed method is used and the mortar has delaminated from the supporting layer or when the subfloor itself is not sufficiently thick or well attached.
In many cases the crack is not the result of an inferior tile.
Depending on what s happening underneath the flooring these kinds of problems may be caused by among other things structure settlement or weak underlayment.
If the floor has too much deflection that grout can crack among other things.
The snapping sounds are almost always traced to an uneven subfloor.
Cracked tiles on floors and walls is a problem because it can be difficult to track down the source of the crack.
Perhaps the tiles are still partially attached at the corners or somewhere in the middle but it s just a matter of time before a hollow tile begins to crack.
If your tile s crack seems to run along the tile s outer edge closely inspect the crack to determine if it s really on the tile or just.
Subfloors need to be quite flat.
On the other hand if tiles are not bonded well then tiles and grout can crack and make a noise as they crack.
Laminate flooring materials don t tolerate humpy and bumpy subfloors.
Occasionally a floor will sound hollow even when the tile is well bonded.
If the paint is blistering then that could be a symptom of a water leak.
