Structural Engineering questions, answered by experts

Most structural engineers offer free quotes, regardless of the size of the job. For simple inspections when buying or selling a home, engineers typically charge a flat fee that may be based solely on your home’s foundation type and square footage. For larger projects, like new construction and major home renovations, an engineer will either perform an analysis of your project and site and provide you with a formal estimate, or they will do a more in-depth assessment and in-person site inspection before coming up with a per-hour or per-project cost estimate. In most cases, the estimate is free.

According to the Earthquake Country Alliance—a public and private alliance in California that works to improve earthquake and tsunami readiness—reports that unreinforced masonry, such as stone, bricks, and hollow clay tiles, is more susceptible to earthquake damage. The mortar between bricks isn’t as stable as other building materials and methods.

Costs depend on furniture type, size, complexity, and whether additional modifications are needed.

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.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.
