I closed on my newly built house last Jan. The warranty has now expired, and conveniently enough, there are vertical cracks in the grout of my stand up shower.
I spoke with someone at Lowes about it (he said he had built new homes up north for a while before coming to Florida). He asked how the tile was laid - ie, was it laid over standard sheetrock, or did they use cement backerboard.
I really was not sure, to be honest - however it seems that it may be laid over general sheetrock. He said that if the shower was tiled over standard sheetrock that the sheetrock may deteriorate quickly over time, resulting in a lot of expensive damage.
Considering that the wall does not sound very dense when you knock on it, I am wondering if the builder cheaped out and just used standard sheetrock.
Is there any sort of building code that requires the use of concrete backerboard for new constructions (in the bath areas)??
I am really worried now, as I know that the grout already has to be redone in those areas, but I really didn't want to worry about this other crap now.
Does anyone have any knowledge of this?? By the way, I'm located in Orlando Florida.
