I'm not an expert...but I have owned a few houses with natural stone finishes and with Acme brick facades. If your materials are natural stone and if they have not been sealed, then they can absorb some water and even transfer water to the stone next door. I'm not saying that this is what is happening, I'm just saying that this looks exactly like my last house when the rains would over flow my gutters occasionally.
Thank you Jay.
So if there is no water contact, there should be no transfer, right?
The spill over falls directly to the pool step. I just don't know how that area get that wet if its not from water behind the wall (from the spa, or a back up from the skimmer).
This is a new wet spot I notice today.....pretty sure it wasn't like this before :uhh:
