Basement moisture issue?

We just bought a house that was recently renovated. They painted the basement cinder blocks, however in the corner the paint is flaking at the bottom. Is this moisture? Is this a concern? It is on the side of the house that the septic is on.

It's tough to say, since it was recently renovated; but, it's definitely a possibility.

It could be that the blocks weren't prepared correctly, or the wrong paint was used. A moisture meter will answer the question. It's a little handheld scanner similar to a stud finder that will tell you the moisture content of virtually any material. They can be rented at most tool rental places, if you want to get to the bottom of it yourself. Lots of waterproofing contractors will have one, and may be able to save you some time in figuring out the problem.

Hi Julie,

Chances are pretty much 100% that it is moisture not allowing the paint to stay attached to the block. If your floor is exposed concrete you can tape a 2 X 2 piece of plastic down for 24 hours. If you see condensation then you have water issues. The biggest part is how to fix it.

Chances are pretty low that it is the septic system. It is more likely a grading issue or a downspout that needs to be extended away from your house. Also check any caulking and flashing around the area. If none of that works, call in a pro as David mentioned.

Good luck with it.

Hi, if the paint on the wall is flaking, means that there is moisture in it.

Moreover, mould will start to grow. An inspection on why the wall is wet needs to be done.

Hope this helps.
