"Hired them for a basic residential addition foundation job and they completely screwed up every step of the process. They don’t know how to read plans or pour straight out flat foundations. They don’t pay their subs which is coming back on us now. They won't respond to any communications. A lien has now been filed on the project because of their lack of payment. Shocked at their ineptitude. Very friendly people, but they should not be construction business owners."

Foundation Repair questions, answered by experts

In most cases, yes, homeowners insurance will cover burst pipes, even if they run through your foundation. Not only that, but most home insurance companies will also cover any foundation repair you need done that resulted from the plumbing leak because your insurer will view the leak as an unforeseen and non-preventable issue.

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.

You'll find a slurry of natural and synthetic polymers, rubbers, epoxies, and resins used to bond old concrete to new concrete. The right bonding agent depends on the method of concrete pouring you choose and whether you're adhering concrete over concrete or concrete over sand and gravel. Some concrete resurfacing mixtures contain bonding chemicals as well.

You could DIY the work, but unless you have plumber’s knowledge for identifying and fixing a slab leak and specialized equipment in your tool shed, attempting to DIY your slab leak repair isn’t a good idea. It’s simply not something that the average homeowner can take on themselves, regardless of how many successful DIY projects they’ve got under their belt. You could, however, do something simple like foundation waterproofing yourself to save some money on the post-repair work.

The best way to determine if ceiling cracks are structural is to hire a ceiling contractor to inspect the cracks and provide a professional opinion. That said, you might be able to make an educated guess based on the size and appearance of the crack. Larger cracks, cracks accompanied by sagging or discoloration, and cracks that travel from the ceiling down the walls are all signs of structural issues.
