Structural Engineering Questions and Answers

What does a residential structural engineer do?

A residential structural engineer inspects structural elements, calculates loads, designs beams, footings and framing, and prepares reports or stamped drawings that contractors and permit offices rely on.

Do I need a structural engineer to remove a wall?

If the wall is load-bearing, an engineer can size the beam and supports so loads are carried safely, and many jurisdictions require engineered plans for the permit. An engineer or experienced contractor can help determine whether a wall is load-bearing.

How do I choose a structural engineer?

Look for a licensed professional engineer with residential experience, ask what the visit and report include and whether drawings are stamped for permits. Independent engineers do not sell the repair work.

What affects the cost of a structural engineer?

Cost depends on the type of service, such as an inspection, letter or full design, the project's complexity, site visits, calculations and the number of drawings.

How should I prepare for a structural engineer's visit?

Clear access to the areas of concern, including the attic, basement or crawl space. Share photos, existing plans and a timeline of when you first noticed any cracks or changes.
