"I called five different companies from the Angi list before finding Colonna Consulting. When I called and I explained my situation to Nick (the owner), I immediately knew he was the one. Despite his tight schedule, he managed to fit me in on the same day. We hired Colonna and Nick to inspect our residential structural foundation. Nick responded promptly to my requests and explained everything clearly during the inspection. He completed the report within the same day. Working with him was a pleasure, and his professionalism made the process smooth and stress-free. Thank you very much Nick, for your fast response."

"Cigano identified a number of important changes to my architectural drawings to strengthen my structure (a car port). The changes recommended and implemented to my plans ensured my Town would issue a building permit. The Town had rejected my initial drawings and required its review and approval by a structural engineer or architect. Cigano really came through and its owner was easy to work with and highly professional. I would highly recommend Cigano."

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. 

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.

Any issue that affects the structural integrity or soundness of a home is considered a structural issue. In addition to foundation cracks, other signs of structural issues include roof leaks, bowing walls, sloping floors, gaps around windows and doors, and more.

No, it’s not legal for unlicensed individuals to conduct structural calculations for buildings or building repairs. Not only do licensing requirements prevent DIYers from tackling this project, but mistakes can also be extremely dangerous and put your property and anyone inside or near it at risk of severe injury or even death. You should always hire a licensed and certified local structural engineer to make structural calculations.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation.
