I recently redid my kitchen, which included removing the back splash and putting in new tile, but when I went to remove the old tile, I found that the tile is only attached to drywall. Knowing this was weird, I cut a small hole in the drywall and on the other side was only insulation which led directly to the plastic siding on the outside of my kitchen wall!? I could push the insulation and my brother could see the plastic siding move on the outside.
I know that my neighborhood was build by a cheap contractor, but no plywood or anything? I pulled out all the sheet rock on the wall below the hanging cabinets (above the counter) and found nothing but the occasional stud, which weren't even properly spaced, (they were too far apart.) The summary is this, the only thing keeping the outside for getting in, is plastic siding, insulation, and drywall with tile on it. And the plastic siding isn't water proof.
What do I do? I have owned this house going on four years and I haven't noticed any problems, and the heating bill isn't outrageous. Am I okay or disillusioned. Do I have walls put in before a major incident occurs or do I do nothing?
Edit My concern is with what I need to do, if I need to do anything. Do I put in walls myself because I have been lucky thus far because the water hasn't made it past the siding, or is this system going to hold. I relaize the obvious nature of the question, but has anyone encountered a similar problem, and if so what was the outcome of either side?
