Structural Engineering questions, answered by experts

First, most contractors will have a structural engineer create a report and plan for your project to ensure it’s safe to cut into the load-bearing wall. The contractor will then excavate around the wall, if necessary, measure the opening—allowing for additional space to fit and level the door, and then cut the doorway out. They will likely install a steel lintel as a header over the door for support. Once the doorway is cut out, they’ll demolish the concrete using sledge hammers and masonry chisels, clean up the surrounding concrete, and seal around the door with masonry mortar. 

A structural engineer’s report is almost always worth it, as it can help you avoid buying or overpaying for a home with structural issues. The most important thing the report does for you is provide peace of mind that you won’t have to pay thousands of dollars for structural repairs right after closing on a property.

The costs depend on the type of wood, labor, roofing material, permits, and whether additional storage or enclosed walls are included.

Yes, you can put a doorway in a structural wall; in fact, most exterior doors are set into structural walls. The project is a little more challenging than installing a door in a non-load-bearing wall because you need a structural engineer to assess the wall and make sure it’s safe to create a wall opening. Your engineer’s report will include instructions for your contractor on how and where to install additional supports, like steel headers above the door, to distribute the weight above to the wall on either side of the door.

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.
