Q: Is a structural engineer the same as a builder?

• <div><p>No, a structural engineer is not the same as a builder. A structural engineer is an expert in all things related to the structural integrity of a building. The structural engineer is responsible for calculating the correct materials in terms of load-bearing capacity and overall structural safety. Structural engineers do not perform the actual building of the house or other structures. Rather, the builder executes the plans and designs specified by the structural engineer.</p></div>

Q: Do structural engineers do free quotes?

• <div><p>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&rsquo;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.</p></div>

Q: Is a structural engineer the same as a foundation engineer?

• <div><p>Structural engineers specialize in all aspects of a building&rsquo;s structural integrity, including the foundation. Foundation engineering is a critical part of structural engineering, so structural engineers are experts in foundation design. Many foundation repair companies either have a structural engineer on staff or one they work closely with, so be sure you look for that when deciding <a href="https://www.angi.com/articles/who-do-i-hire-foundation-repair.htm">who to hire for foundation repair</a>.</p></div>

Q: What are the signs of structural damage?

• <div><p><a href="https://www.angi.com/articles/signs-of-structural-damage.htm">Signs of structural damage</a> include foundation cracks, roof leaks, bouncy floors, crumbling concrete, and cracked or leaning chimneys. Structural damage can make itself apparent in various ways, and sometimes, there may not be obvious signs. Inspect your foundation and roof annually to stay ahead of potentially serious structural problems. </p></div>
