Question DetailsAsked on 9/25/2017

contractor is trying to say it may be a foundation problem because the grout on the tile floor they did is out

I had a full kitchen remodel and the grout in the tiles has been coming out since a month after the installation. The contractor gave me a warranty for 2 years, however he keeps asking me if I had the foundation checked on the house. Isn't this something they should have known to check prior to laying down new tile flooring? The previous floor was hardwood (real wood).. I think it's more of a bad tile installation job or grout that they didn't know how to work or mix?

I would say if he wants to hire (at his expense) a licensed/registered (phrasing varies by state) geotechnical (soils and foundations specialty civil engineer) or Structural Engineer to assess the possibility that it is being caused by a structural/foundation issue that would be a fair way to handle his claim - WITH the proviso that the scope of work for the engineer shall designate that he is to be providing an unbiased third-party professional opinion on whether the cracks are caused by a foundation movement or not - and that both parties (you and contractor) shall receive copies of the report directly from the engineer.

Be cautious that it should NOT potentially include structural bowing or movement of the subfloor due only to the weight of the tile as a fault beyond the contractor's responsibility unless it is due to structural "failure" or grossly inadequate supporting framing - slight bowing of the floor beams due to the weight of the tile floor will occur but should NOT cause this sort of cracking.

Otherwise, unless and until he can PROVE it is due to foundation settlement or movement, he should remove and replace the grout under the warranty - or if the tile is coming loose take it all up and redo the job. And BTW - just running a skim coat of new grout or even just cement paste or caulk over the tile to conceal the cracks in the grount does NOT cut it as a proper fix.

I also have a suspicion that this may well be because of the method used to lay the tile - if put down on one of the debonded mat type systems where the tile floor "floats" disconnected from the subflooring like the Schluter Kerdi Board system, that is a common cause of grout cracking - especially if there are a lot of cracks. In my opinion that is flat out a bad way to put down tile (or stone) and an invitation to failure.
