Concrete Repair questions, answered by experts

It’s usually not an immediate safety risk to live in a house with foundation problems, but you don’t want to let those problems persist. Most foundation issues don’t lead to a house’s sudden collapse, but they can lead to health issues like mold growth and pest intrusion, as well as problems like uneven floors or rotten beams and joists, which can pose injury risks and be costly to fix.

Foundation problems will likely get worse over time if they aren’t repaired. As foundation problems progress, your home may experience signs of structural damage, water damage, and health and safety risks—all of which will only get more expensive to fix the longer you wait. Repair foundation problems as soon as you’re aware of them to avoid complex and expensive remediation in the future.

Most building departments will require that a certified and licensed foundation repair professional or a structural engineer pull permits for foundation repair, so homeowners usually cannot pull them themselves. This helps ensure that an experienced professional completes all structural work on your home. Minor repairs that are technically DIYable often won’t require permits, but it’s still a good idea to hire a professional to carry out foundation repairs.

No, hairline cracks in concrete are generally not a problem as they do not impact the strength and longevity of the concrete. Generally, cracks less than 0.3 millimeter wide don’t impact the structure. Hairline cracks can grow over time and weaken the structure, such as in a home foundation. Some hairline cracks can also cause leaks in a foundation. It’s important to watch the cracks to see if they grow. Contact a concrete contractor if you notice cracks exceeding 0.3 millimeter wide.

Yes. Water can penetrate through a concrete foundation wall. This can happen whether or not you have cracks, as concrete is a porous material. You’ll want to take steps to waterproof your basement or crawl space.
