Thanks for the response.

I guess what my question was - should I be worried about anything else like the shell of the pool? Its 10+ years old and both inspectors didn't see anything other than it needing a re plastering in a few years.

I'm also wondering roughly how long it could take for water going down in those cracks behind the coping to be a problem. I'm relatively new to the area - but I do know this isn't the area of central texas where there is a lot of clay in the ground.
