Please advice me as I am thinking of buying a house which has two crack s in the basement floor almost 1 cm wide all over the floor & there are also cracks in the Garrage floor & also cracks in the driveway but the house is well priced & good .I am just worrying about these cracks . What will be the results of these cracks . May it result in the roof & walls cracks too.as house was built in 2008.
