I am getting really close, like next week, of contacting a realitor to put my house on the market. Today, i was cleaning out the garage and see a 1/4 inch crack right up the center of my garage leading straight into the middle of my house which is my laundry room, We have had tons of rain in Mississippi this year and I noticed 2 tiles in my laundry room busted so I had them replaced last week and cant say I remember there being a crack under the tiles.

What am i to do with the crack should I try to seal it or just leave it as it. My house is 25 years old.

Should I try to put a coat of something on the garage floor..

Please help
