Structural Engineering questions, answered by experts

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.

If your home's foundation was damaged due to shifting soil, the same problem will reoccur unless you stabilize the structure by adding posts in the bedrock.

Squeaky floors don’t always mean structural damage. Usually, it’s caused by friction somewhere inside your floor—whether it’s a loose floorboard or a gap between the subfloor and joists. If there is structural damage, you’ll notice other signs like soft or sagging floors, cracks that go from the wall to the ceiling, and horizontal cracks on your foundation.

A 4-inch-thick concrete slab can support around 4,000 pounds per square foot if a contractor reinforces the slab with rebar, while that same slab without reinforcements will support closer to 1,000 pounds. For the purposes of a patio, 4 inches in thickness without reinforcement should suffice unless you’re installing heavy kitchen equipment or a hot tub on it. In those cases, reinforcing your slab and sticking with 4 inches of thickness should provide plenty of strength.

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.
