So I agree with the earlier post. In situations like this eliminate the easy stuff first and work towards bigger issues. So check that downspouts are not clogged, that splash blocks are installed below them, and that water is directed away from the foundation. All soil around the house, including flowerbeds needs to slope away from the house. If all that checks out OK, then it's probably a foundation drainage issue. Have you had a lot of rain recently? The water table could be elevated if you have, and then imagine all that water (hydro-static) pressure pressing in on the foundation. If you have the proper drain tile/ gravel around the perimeter of the foundation then that pressure is relieved and the water gets drained away, if not, well you can get water in your house. Water can also force its way up through the floor as your photos show. As you can imagine, if the foundation drainage is not adequate or there to begin with it could be costly to fix, but definitely work on all means to divert water away from the house first as this can make a huge, and sometimes all, the difference.
