5 Signs you need a Structural Engineer

Written By Kamal Ahmed

1. Large or Growing Cracks in Walls or Foundation

Cracks are one of the most common indicators of structural problems. While small hairline cracks can be normal, large, widening, or recurring cracks may signal foundation movement or structural stress.

You should contact a structural engineer if you see:

  • Cracks wider than ¼ inch

  • Stair-step cracks in brick or masonry

  • Cracks that keep returning after repair

A structural engineer can determine whether the issue is cosmetic or a sign of deeper structural damage.

2. Sagging or Uneven Floors

Uneven, sloping, or bouncy floors often point to problems with load-bearing elements beneath the surface. These issues can worsen over time if left unaddressed.

Common causes include:

  • Weak or undersized floor joists

  • Foundation settlement

  • Damaged beams or supports

A structural engineer will assess the load distribution and recommend safe, code-compliant solutions.

3. Doors and Windows That Stick or Won’t Close Properly

If doors and windows suddenly stop opening or closing correctly, structural movement may be the cause. As a building shifts, frames can become misaligned.

Watch for:

  • Doors that swing open or shut on their own

  • Gaps around window frames

  • Cracks forming near door or window corners

These are often early warning signs of foundation or framing issues.

4. Structural Concerns After Water Damage or Flooding

Water exposure can significantly weaken structural components such as wood framing, steel beams, and foundations. Even after visible repairs, hidden damage may remain.

Call a structural engineer if you notice:

  • Rotting wood or rusted supports

  • New cracks after flooding or leaks

  • Ongoing moisture near structural elements

A professional evaluation ensures the building is still safe and structurally sound.

5. Planning a Renovation That Involves Load-Bearing Walls

If you’re planning a remodel—especially one that involves removing walls or adding weight—a structural engineer is essential.

You should hire a structural engineer when:

  • Removing or altering load-bearing walls

  • Adding a second story or heavy fixtures

  • Converting basements or attics into living space

This ensures your renovation meets building codes and doesn’t compromise structural integrity.

When in Doubt, Get a Structural Inspection

Structural problems rarely fix themselves, and delaying an inspection can lead to higher repair costs and safety risks. Hiring a structural engineer provides clarity, peace of mind, and expert guidance—before small issues turn into major failures.

If you’re unsure about your building’s condition, a professional assessment is always worth it. Please always reach out to us for any enquiry.
