Even if it was "properly" abandoned years ago, the possibility remains of soil contamination below the tank.

As you clean the walls, you won't have to worry about peeling off the latex to expose lead paint underneath.

I pulled up the carpet and look and behold: the floor underneath was perpetually damp from a leak.

Underneath everyone's avatar (the picture) in each post is a "xx posts".

What's underneath the tile?

The first thing is to make sure the soil slopes away from the home and gutter/downspouts are in working order.Other than having a good working sump pump, other methods I know can be hit or miss in effectiveness.Some people have had good luck installing a french drain system in the yard to carry away excess water to the low point of the lot.

So the land underneath those buildings don't have maintenance costs.

I'm trying to say there's more motivation underneath than just money even though money is a big part.

So instead of knocking holes, patching them, which was not the problem, I instead had a new vanity installed, not made with particle board, but wood, and with rubber underneath to raise it slightly above the floor.

Are there parts of the city or zip codes that are (generally) more or less likely to have foundation problems due to the type of soil/clay/stone houses are built on?
