Structural Engineering questions, answered by experts

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.

Most load-bearing walls are exterior, though they can also be interior.

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.

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.

Structural engineers can perform various inspections on different structures in your home. These inspections usually include a report detailing the engineer’s findings and recommendations for repairs so you can determine your next course of action for repairs, replacements, or new builds. Some of the most common structural engineering reports include:

  • Full home inspection: $350–$1,000

  • Foundation: $300–$800

  • Load-bearing walls: $300–$1,000

  • Roof: $150–$600

  • Chimney: $200–$500
