09 Feb Foundation Issues
Hairline cracks in foundation walls might be the result of concrete curing or minor settling and aren’t automatically cause for alarm. Mark them with tape and check them again in a few months. If they’ve worsened, call a structural engineer. If they’re stable, fill them with a grout or spray foam in a can.
What you can do:
- Fill in holes in siding and foundation walls with expandable foam.
- Check that the ground around the foundation slopes away from the house (about 1 inch per foot).
- Clear the area of leaves, in which rodents can nest.
