"After calling StructuralMD and confirming that this service was what we needed, an appointment was quickly set up and George (Chief Engineer) showed up on time. He closely inspected the area in question and provided a great deal of detail regarding his findings. George answered every question we had and spent whatever time required to provide additional guidance, suggestions and tips. His inspection confirmed that there were no structural issues, and helped us prepare to hire a contractor to complete the (non-structural) work that we originally sought. He also urged us to contact him again to ask any other questions that might have. A professional outfit with excellent customer service!"

"Mina is extremely knowledgeable, clear, patient, and upfront. I never hired a structural engineer before and was feeling intimidated by the process. Kiro Engineering understood my issues and home renovation desires and provided me several solutions to make sure the result was safe and properly executed. Through conversation it was clear that Kiro is equally at home dealing with a homeowner like myself as well as very high end extensive and commercial projects. I can’t recommend Kiro enough for any structural engineering projects."

"Very professional experience with Mina, the engineer who thoroughly explained his findings and suggested remedies. He confirmed house settlement suspicions and causes in a lengthy, detailed report complete with photos. I trust Kiro Engineering and would highly recommend them for structural engineering consultation and peace of mind."

"We contacted Cowan's during the busy season, he responded by text only. We explained what we needed. It took about 2 weeks of texting and trying to getting responses to final set a time for him to come out. One of his workers came and did the cleaning. He did not cover anything around the stove, he left hand and foot (soot) prints everywhere he touched and walked. He left my fromt door open the whole time he was here (35* degrees outside) He did a partial job of cleaning up after himself. When I mentioned to him about the marks he left, all he could say was I don't have rags to clean. I spoke to Mr. Cowen about how unhappy I was with the way things were left and he said he would talk his worker and just use soap and water to clean everything. I should not have to clean up after Cowan's job. When I offer to pay him he told me to keep my money and Goodbye."

"Brian from Concrete & Masonry Pros LLC partnered with me the entire way; he made suggestions and helped me select the right design for a walkway, patio, and landscaping wall and the work came out great!  When a section of it didn't come out as planned, he came back on the weekend to fix it.  Top job!"

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. 

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

Structural engineers specialize in all aspects of a building’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 who to hire for foundation repair.

Yes, ceiling joists are typically load-bearing. However, their primary function is to support the weight of the ceiling and loads applied to it, like lighting fixtures and ceiling fans. They can also help support the roof, especially if they’re part of truss systems. Remember, the load-bearing capacity of ceiling joists depends on the material, size, and space between them. 

The depth of any foundation style depends on your climate and how deep the frost line is, as building code requires that the footers of a foundation—which are built into a monolithic slab—sit at least a foot below the frost line. At the southern tip of Florida, for example, a monolithic slab foundation would only need to sit 12 inches under the soil at the widest parts. On some parts of the Canadian border, the frost line is 100 inches, which would mean a minimum of 112 inches, which is prohibitively deep for a monolithic slab.
