Newer home owner here. I have these cracks on the foundation of the house. Behind them is a crawl space open to dirt. How should I fix or address these? Do they need to be fixed? I try and DIY as much as I can so don't be afraid to suggest a DIY solution. I'm also not above getting professional help, I just haven't had to thus far.
When you bought the home, what did your home inspector say about the foundation cracks?
Call a professional to do a foundation inspection. Your cracks might be nothing or they could be serious. Only a foundation expert can tell you for sure.
