"I am having a full master bath and kitchen remodel done with new layouts in both rooms and knocking out a wall. Evolution worked with me to quickly get a drawing done of the new layouts so that the contractor could get started on the project. They made sure to include me in the process so that the design would be done exactly as my wife and I envisioned. They communicated effectively throughout the process and were always courteous and professional. I recommend them to anyone with drafting needs."

Structural Engineering questions, answered by experts

Building codes for spiral staircases will vary by your location. Most local codes will specify minimum tread width, riser height, handrail requirements, and headroom. These standards help ensure safety and accessibility for all users. Always check local codes before you begin the installation to ensure compliance and avoid costly modifications or fines.

Costs depend on material choices, labor, and the extent of structural modifications.

Proper licensing and experience in residential and commercial structural projects.

Yes, you can build over a stump if the roots are no longer alive. Living roots will continue to grow and may damage your new construction over time. Similarly, you should also remove rotting stumps because they may continue to attract pests and even cause new structures (especially those made from wood) to decompose as well.

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
