Twice this year we have had water in basement. It seems to only come from cracks in floor. Only lived here a year. Water has come in latter part of summer and fall. We have a very cracked cement drive that I know has to come up. But the water is coming in the other side of the basement thru the floor. Do I need a sump pump or might this be a "city" problem. How do I tell, who do I call? A plumber or a pump guy or the city? Any advice welcome!!
