Structural Engineering questions, answered by experts

It’s possible to drill into an LVL beam, but you should always avoid it. LVL beams are major structural components of your home, and drilling into them can weaken them and lead to cracking over time. If you need to drill into an LVL beam, consult a structural engineer. They’ll know the bit size, depth, and directionality that’s safe to use when drilling.

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.

Cathedral ceilings make a statement in your home, but at the cost of your attic space. Normal attics are wide open, which allows warm air to move around and exit your home. Because of this, cathedral ceilings make your home less energy efficient and put your ceiling at risk of venting issues if you’re not careful. They also reduce your attic storage space, potentially cause an echo, and even make it harder to change a light bulb.

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.

The depth of any foundation style depends on your climate and how deep the frost line is, as building code requires that the footers of a foundation—which are built into a monolithic slab—sit at least a foot below the frost line. At the southern tip of Florida, for example, a monolithic slab foundation would only need to sit 12 inches under the soil at the widest parts. On some parts of the Canadian border, the frost line is 100 inches, which would mean a minimum of 112 inches, which is prohibitively deep for a monolithic slab.
