I noticed a crack on our basement wall or foundation wall (not sure what to call it). Our house is fairly new, built on mid 2017. We have a finished basement so there's no way to check the crack from inside unless I remove the basement interior wall. Is this something we should be worried about? Should we get a professional to check this or at least patch it if it's not a serious damage? Thanks in advance for any inputs!
That is not a problem and quite common. I would put a tape measure in the photo and take a photo then check it in a year, no change no big deal. Large change then con aging the builder may be a good idea. Also keep an eye on the earth below if the ground is going away (sink hole or settling) their may be a larger issue but small cracks are quite common.
