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.
I’m not an engineer.
If the crack is moving then you need to address it pronto. If it’s not moving and has been there for years then it’s probably fine.
