"I would (and almost certainly will) work with AGGO again! We are buying a house and something came up where we needed a structural engineer to inspect something on very short notice. I reached out though Angi's to any company that might possibly employ structural engineers and Linda, a Structural Engineer with AGGO got back to me right away, first thing in the morning and was able to squeeze us in that very night. Linda was thoughtful and thorough. She careful looked over everything and even brought a large, bright light since it was after dark. She took her time, answered all of our questions, and gave us advice on other concerns and things to watch out for as well as reassuring us about things we didn't need to worry about in this situation. Even though she was probably working past her normal work hours to squeeze us in, nothing felt rushed or hasty."

"I am having a full master bath and kitchen remodel done with new layouts in both rooms and knocking out a wall. Evolution worked with me to quickly get a drawing done of the new layouts so that the contractor could get started on the project. They made sure to include me in the process so that the design would be done exactly as my wife and I envisioned. They communicated effectively throughout the process and were always courteous and professional. I recommend them to anyone with drafting needs."

"I had a fantastic experience working with this drafting firm. From the very first phone call, Kirsten?our drafting consultant? was clear, professional, and incredibly helpful. She explained the entire process in detail and made sure all of my questions were answered up front, which gave me immediate confidence in the team. This firm partnered with engineers and architects to get the best quote for me on a stamp for my plans after they did an exceptional job on drawing the prints that met all the requirements for permitting. Their coordination and attention to detail made the process very simple on my end. If you are looking for a highly capable drafting firm that knows how to get things done right, I highly recommend them!"

Structural Engineering questions, answered by experts

The best way to determine if ceiling cracks are structural is to hire a ceiling contractor to inspect the cracks and provide a professional opinion. That said, you might be able to make an educated guess based on the size and appearance of the crack. Larger cracks, cracks accompanied by sagging or discoloration, and cracks that travel from the ceiling down the walls are all signs of structural issues.

Yes. Foundation walls are always load-bearing.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

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. 

A 4-inch-thick concrete slab can support around 4,000 pounds per square foot if a contractor reinforces the slab with rebar, while that same slab without reinforcements will support closer to 1,000 pounds. For the purposes of a patio, 4 inches in thickness without reinforcement should suffice unless you’re installing heavy kitchen equipment or a hot tub on it. In those cases, reinforcing your slab and sticking with 4 inches of thickness should provide plenty of strength.
