My gun is ready to caulk

I have this mysterious water leak in my basement laundry room and just when I think I have found the source and fixed it, I find water on the floor again.  The exterior wall where the water seems to be coming in is on the side of the house where the rain usually hits.  It is also the wall with the electric meter, dryer vent, a window and other entry points for wiring.  We have already caulked around the dryer vent and around the electric meter where the concrete had crumbled and was no longer doing its job.  I took a good look at that wall and noticed a gap in the window sill mortar joint.

To fix the gap, I bought some silicone caulking that is for concrete.  The kind I bought has a 30 minute rain ready time, which was good because we have been having a lot of rain.  I checked all the window sills and found a couple more that needed repair that I took care of as well.

This caulking does not clean up nice with water and I found my hands were covered in a sticky film.  I rubbed some sand on my hands and that got rid of the stickiness.

I also have a crack in the garage floor where moisture seeps up into the garage.  Since I have almost a full tube of caulking left, I will use it to fill that crack too.

Have checked your window sills lately to see if there are any cracks and gaps?
