Q: For which type of foundation cracking should a structural engineer be recommended?

• <div><p>The <a href="https://www.nahb.org/">National Association of Home Builders</a> requires repair of any foundation crack of more than one quarter of an inch, although local regulations may vary. In general, any visible crack that is growing in size, allowing water through, or that you have just noticed, is a good reason to call a structural engineer. Cracks can be a sign of a <a href="https://www.angi.com/articles/sinking-foundation.htm">sinking foundation</a>, so an inspection is a good idea for your peace of mind.</p></div>

Q: Is a pier and beam the same as a crawl space?

• <div><p>Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as &ldquo;crawl space foundations,&rdquo; but the crawl space itself is separate from the foundation. </p></div>

Q: Can a one-story house have a load-bearing wall?

• <div><p>Yes, a one-story house can have a load-bearing wall. The load-bearing walls in a single-story home are usually the exterior walls. If the house has a basement with exposed walls, the arrangement of the beams can help indicate what walls are load-bearing.</p></div>

Q: Can I cut or drill LVL beams?

• <div><p>It is not recommended to cut or drill into LVL (laminated veneer lumber) beams. As major structural components of a home, their composite structure can be compromised by alterations, which can weaken them and lead to cracking over time. If you must make modifications to an LVL beam, it is crucial to consult a structural engineer or general contractor first. A professional can advise on whether it's safe and provide specifics on the appropriate bit size, depth, and directionality for any necessary drilling.</p></div>

Q: Are all exterior walls load-bearing?

• <div><p>It's safe to assume that all exterior walls are load-bearing, or at least have load-bearing characteristics. Some older homes feature porches or bump-outs that don't rest on the home's foundation. However, they still must carry the weight of the roof section they support. Walls containing floor-to-ceiling glass or other non-structural elements must use post and beam configurations to meet load-bearing criteria. </p></div>
