floor tiles have several hairline cracks and chipped corners. The house is just 2 years old?

Sounds like a stress crack and not a faulty tile.Faulty tile won t just appear, it shows up in the box and is seen right away or a "craze" will appear when grouting and those type lines will be random and all over. I need more info or pictures to help determine just what the cause may be. Need to know about the substrate that the tile is on. Cement? You on a wood subfloor and did they add another subflooring atop the regular subfloor? Any answers to these questions you can e mail me through my avatar and check my qualifications there. GL

hi andi

i'm not the expert on floor tile, most my experience is with vinyl. it sounds like you may have 1 of 2 problems, or both. the sub floor my not be properly installed, not strong enough or not secured right (of course this is only if the floor is wood). the other is when the glue was applied they didn't use enough glue. the glue acts as a leveling agent. if there is not enough you have pockets of air under the tile or the tile is in contact with the sub floor. both of which will cause the tiles to crack.

getting a flooring expert to look at it is a good idea. then send a certified receipt letter to the builder stating his findings. this might help with his lack of response.

good luck.

If you know the brand name of the tile you may want to contact them and see if there is a recall on these tiles. It could be the tiles fault and not the contractors.

sound like you might have a settlement or shrinkage problem and possibly poor installation. you should call in an independent to verify which or both before having it repaired or redone.If it's repaired over an inferior substrate it will just happen again

They have to re-do the tile
