You might be tempted to caulk any gaps that open in your home. However, this method fails to address the actual problem of foundation damage. Even if caulking or other DIY methods appear to close a gap for a time, it’s only on the surface level. Foundation damage is still occurring, and the gap will only get larger.
The only way to truly seal wall gaps is with foundation repair options like pier systems or wall anchors. Professional foundation repair can prevent gaps from opening in the future because they offer a permanent solution to foundation problems. So, you can’t close gaps on your own – the best thing to do is hire a professional.
