"So I originally had an appointment for March of 2026 because of weather and they are booked. I understand now why. Monday morning I received a call from Forman Carter S and he said looks like he can get me done before winter. I was pleased and excited to get my porch fixed. So he came out the next day he had available. That morning he called me let me know he was on the way and made sure the timing would work because I had an appointment to go to. Since he called me that Monday communication was perfect had no issue getting a hold of him. They showed up we went over what he is going to do and how it was. He also took steps make sure that the lifting foam was going mess up my basement so he ensured that the foam would stay outside. He treated my house like his own. Before I left my 30 min appointment he texted me saying they were wrapping it up. It looked amazing. I want to thank Carter and Riley for their great work. They clean my porch and picked up everything before leaving."

Construction company and consulting engineering firm for residential, industrial, commercial, institutional, and retail clients.

"Had Betts Structural Engineering come and look at the foundation of a house we were in contract on. Josh came out and was professional and informative. He informed us the foundation was failing and explained what needed to be done. He throughly explained everything and told us how we could do it ourselves for much cheaper than a contractor could do it. In the end he saved us from a long and expensive process if we proceeded with the house."

Structural Engineering questions, answered by experts

Yes, floor joists are essential structural components. They support the weight of floors and everything on them, transferring loads to the foundation and walls. Properly installed joists are necessary for maintaining strength, stability, and structural integrity.

While concrete walls do not need to "breathe" in the traditional sense of the word, they do require waterproofing and dehumidifying methods, particularly in basements below the water table. Concrete both contains moisture from its initial installation and can absorb water when exposed. Ensuring proper basement ventilation , installing a vapor barrier, and controlling water exposure are all important tasks.

In many areas, advice from a structural engineer or an architect will be required by your building department before you can remove a wall, but even if it’s not necessary, it’s a good idea. Accidentally removing a load-bearing wall—even if a general contractor advises that it’s safe—can cause major structural damage, putting you and your family at risk and potentially costing thousands or tens of thousands of dollars in property damage.

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.

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.
