Structural Engineering questions, answered by experts

Through proper drainage solutions and compacting the foundation soil.

Yes, water damage can affect your walls' structural integrity. If the water or moisture sits on the walls for an extended period, it can weaken the drywall, plaster, wood framing, and other materials supporting the wall. That's why it's critical to dry out the area as soon as you notice it.

If you’re building new construction or adding onto your existing home, hiring a structural engineer is not only worth it but it’s probably required by your local building department. Structural engineers will ensure you aren’t making your home unsafe in the building process, which is crucial from a safety perspective but also a legal one. It’s also worth hiring a structural engineer if you’re making changes to structural components, like removing a load-bearing wall.

Yes, you can put a doorway in a structural wall; in fact, most exterior doors are set into structural walls. The project is a little more challenging than installing a door in a non-load-bearing wall because you need a structural engineer to assess the wall and make sure it’s safe to create a wall opening. Your engineer’s report will include instructions for your contractor on how and where to install additional supports, like steel headers above the door, to distribute the weight above to the wall on either side of the door.

Yes, all states require structural engineers to carry the proper license, with specifics determined by each state. You can use Angi’s state licensing tool to confirm that the structural engineer you’re considering holds the required licensing to tackle your job. Hiring an unlicensed structural engineer will not only cause issues with permits but it could also lead to an unsafe building. The cost of a professional, licensed, and experienced engineer is well worth the investment.
