Foundation Repair questions, answered by experts

Minor slab leaks normally take around three hours to access and fix, provided the leak is in an accessible location. However, a more extensive leak or a leak in a hard-to-reach location can take several days to fix, depending on the resulting damage. You might also want to consider the timeline for the build-back if the leak damages building materials like flooring or cabinets, which can take several weeks, including delivery of the materials.

Tree roots don’t necessarily break through concrete on their own, but they can certainly take advantage of existing cracks, even very small ones. As roots grow, they expand the cracks, making them larger and leading to serious and costly foundation damage. It’s a good idea to have repairs on any foundation cracks you’re concerned about.

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.

A slab-on-grade or slab foundation is a great option in many areas—usually in warm or moderate climates—and has been a successful foundation style for many decades. Slab foundations don’t require excavation or concrete block wall construction, so they’re the least expensive foundation type. They’re also the fastest to construct and don’t have many issues with moisture or water intrusion. However, they don’t give you extra storage space or potential living space like a crawl space or basement would, and they’re not ideal in colder areas where utility lines can freeze and frost heave can cause major damage.

Homeowner’s insurance doesn’t cover foundation cracks unless they’re a result of a natural disaster like an earthquake, vandalism, or a vehicle accident that causes sudden damage. Taking care of your foundation to prevent problems with expansive soil and drainage is considered ongoing maintenance, and your insurance company expects the homeowner to carry out that preventative maintenance.
