When we closed on our new construction home two years ago, there were lots of hairline cracks in the slab. We had two inspectors come out, even had one come out right after the slab was poured, and they said it was fine, but that if we were ever concerned about shifting they could come out and do a more in depth future study. The cracks in our garage are what worry my husband most, as it seems to be expanding. I’ve attached pictures of how wide the crack is at the widest. It doesn’t seem thin enough to be hairline, but all the forums I’ve read say don’t worry until it’s 1/8th"+ wide. The crack runs along the entire length of the garage floor, turns along the corner where it stair steps up, and then a crack there looks like it goes into the house but it really just dead ends. There is another similar crack in another place in the garage.
Also, we have cracking tiles in our mudroom (off garage) and in our foyer (other side of the house).
All walls and windows and doors are fine.
Summer where we are located is usually very dry, and it was very dry for about two months, but we’ve received a lot of rain over the last month.
Is this something we should be concerned about?
