I have a new home built a year ago. I noticed that there are various cracks on my basement wall and floor. What concerns me most is the diagonal cracks at both of the basement windows. Also the cracks on the floor is "Y" shaped and about 1/16'' in width. I noticed the two sides are not level. It's toward the end of one-year warranty period. The builder came in yesterday and said he didn't think there was problem or there would be a problem, so no repair was necessary. I am not so sure. I think if I don't say a thing now, they are off the hook. Because there are so many cracks I am afraid it's going to affect the resale value, not mention the potential of high repair expense.
Does any one has any suggestion? What's builder's responsibility here?
